Part 7: Names Hasbro had to find a substitute for because someone else had claimed them in the meantime, or holds a "confusingly similar" trademark

Over the years, quite a few names which Hasbro originally used for Transformers toys were claimed as trademarks by other companies. As a consequence, Hasbro can no longer use them. In most cases, the competing company doesn't have the exact term that was used as a Transformers toy's name once, but merely a very similar term, so Hasbro's lawyers fear their competitor might file a lawsuit for copyright infringement because they would deem the Transformers toy's name "confusingly similar" to their own trademark. In both cases, Hasbro prefer to come up with substitute names to avoid any legal trouble in the first place.
In particular, the names Hasbro currently have to use substitutes for are:

[ Hot Rod | Bluestreak | Trailbreaker | Overdrive | Mixmaster | Powerglide | Slingshot | Outback | Shrapnel | Runabout | Motormaster | Hook | HiQ ]

Hot Rod. Following the release of the original Autobot Car toy in 1986 came a Targetmaster version of the toy (still called simply "Hot Rod") that was available one year later, in 1987. After that came a large gap in the release of new "Hot Rod" toys. The first time the name "Hot Rod" actually became relevant to Hasbro again following that was in 2002, when Hasbro released a Super-Con toy as part of the Armada line that was loosely based on the original 1986 Hot Rod character (although one might argue whether it was actually a cross between the original 1986 Hot Rod character and the original 1984 Bumblebee character), with Takara's Micron Densetsu version of the toy actually being called "Hot Rod" in Japan.
However, in 1995, Mattel registered the term "Ho! Ho! Hot Rod", to be used for "toy vehicle and accessories", followed in 1999 by "Hot Rods", to be used for "activity toys, namely, snap together construction toys". Even though Mattel have since abandoned the registration for "Hot Rods" in 2004 and the one for "Ho! Ho! Hot Rod" in 2006, they have since registered the term "Hott Rodd", to be used for "toys, games and playthings, namely, toy action figures; parlor games", in 2006, and are currently attempting to register the term "Holiday Hot Rods", to be used for "toys, games and playthings, namely, toy vehicles and accessories therefor", as well. As a consequence, Hasbro chose to release the Armada toy under the name "Hot Shot" instead, a name that had been originally used for a Spychanger (a redeco of Generation 2 Go-Bot Blowout) that was available in various decos as part of the Robots in Disguise line starting in 2001. Aside from the Spychangers, the name would also be used for a McDonald's Happy Meal toy representation of the Armada toy, a "Powerlinx" redeco of the Armada toy, a "Built to Rule" representation of the Armada toy, an Energon Combat Class toy, a Cybertron Deluxe Class toy (which was later also available as a Wal*Mart exclusive repackage with a "Tiny Tins" redeco of the Armada Mini-Con Mirage and as a Target exclusive two-pack with Cybertron Override, called the "Drag Race Pack!"), a Legends of Cybertron version of the Cybertron Deluxe toy and a redeco of the Legends of Cybertron toy.
Meanwhile, a Commemorative Series I reissue of the original 1986 Hot Rod toy released by Hasbro in 2002 ended up being named "Rodimus Major", a name which would ultimately never be used again afterwards. Following that, the next opportunity for Hasbro to release a toy based on the original 1986 Hot Rod character would have been a redeco of the Heroes of Cybertron Rodimus Prime PVC from 2003, which was released by Takara as part of their SCF version of the line in Japan; however, Hasbro chose not to release the redeco in the USA, and thus avoided having to use a substitute name again for the time being.
Eventually, in 2006, Hasbro released a Classic Deluxe toy that was based on the original 1986 Hot Rod toy, this time simply named "Rodimus", a name originally used for an Energon Combat Class toy from 2004 that was loosely based on the original Hot Rod/Rodimus Prime character (named "Rodimus Convoy" in Japan, Takara's name for the original 1986 Rodimus Prime toy). Interestingly enough, however, the name "Rodimus" had previously already been used for a "matured" version of the Hot Rod character that appeared in the Wreckers comics from 3H Enterprises, with a mock-up catalog even depicting the original 1986 Hot Rod toy, referred to as "Rodimus" rather than "Rodimus Major". The name "Rodimus" would later also be used for a 3" Titanium figure, a Robot Heroes figure (available as a two-pack with Insecticon) and a redeco of the Alternators Mirage toy that was exclusively available at San Diego Comic-Con 2007 and the Hasbro Toy Shop website, even though the instructions for the latter toy featured the name as "Rodimus Prime®" for whatever reason.
Hasbro trademarked the name "Hot Shot" prior to the release of the Armada Super-Con toy from 2002, which was the first toy to sport a ™ after that name. Hasbro successfully registered "Hot Shot" in 2003, with the first toy to sport an ® after the name being the Cybertron Deluxe Class toy from 2005. Hasbro trademarked the name "Rodimus Major" prior to the release of the Commemorative Series reissue from 2002, which was the first and only toy thus far to sport a ™ after that name. Thus far, Hasbro have not attempted to register the name "Rodimus Major". Hasbro trademarked the name "Rodimus" prior to the release of the Energon Combat Class toy from 2004, which was the first toy to sport a ™ after that name. Hasbro successfully registered "Rodimus" in 2005, with the first toy to sport an ® after the name being the Classic Deluxe toy from 2006.
Compound trademarks that included the name "Hot Shot" were "Energon Hot Shot", the Combat Class Hot Shot redeco from the Energon toyline, and "Cybertron Defense Hot Shot", a Deluxe Class toy from the Cybertron toyline, with the names being featured as "Energon Hot Shot™" and "Cybertron Defense Hot Shot™", respectively. Meanwhile, the "Powerlinx" redeco of the Armada Super-Con was referred to on the packaging as "Powerlinx™ Hot Shot™", hence making it a sequence of two separate trademarks rather than a compound term.

Bluestreak. Following the release of the original Autobot Car toy in 1984 came a large gap in the release of new Transformers toys using the name "Bluestreak", although there was a vehicle from Hasbro's "C.O.P.S." line using the name "Blue Streak" which was available in 1989. The first time the name "Bluestreak" actually became relevant to Hasbro again following that was in 2003, when Hasbro released a Commemorative Series III reissue of the original 1984 Bluestreak toy. However, in 2002, a company named Gendron, Inc. had registered the name "Toledo 'Blue Streak'", to be used for "toy vehicles and miniature collectible vehicles", so Hasbro chose to release the Commemorative Series reissue under the susbtitute name "Silverstreak" instead. The same name was later also used for a KB Toys exclusive redeco of the Robots in Disguise Spychanger Side Swipe toy in a deco based on the originally intended color scheme for the original 1984 Bluestreak toy (which was later also available at Dollar General and Family Dollar stores in "Universe" packaging) and the Alternators toy (a redeco of the Alternators Smokescreen toy, although in terms of development, Silverstreak was the original design and Smokescreen the redeco). A redeco of the 3" Titanium Smokescreen figure was also planned, but would ultimately never be released.
Curously enough, in 2006, Hasbro intended to use the name "Bluestreak" for a redeco of the Alternators Prowl toy, with the deco being based on the originally intended color scheme for the original 1984 Bluestreak toy. However, even though the vehicle mode's license plate of packaged samples still sported an abbreviated form of the originally intended name, "BLU STRK", the toy's name was ultimately changed to "Autobot Camshaft", with the vehicle mode's license plate of the version actually available at retail sporting an abbreviated form of that name, "CAM SHFT", instead.
Hasbro trademarked the name "Blue Streak" prior to the release of the C.O.P.S. vehicle from 1989, which was the first and only toy to sport a ™ after that name. Hasbro trademarked the name "Silverstreak" prior to the release of the Commemorative Series reissue from 2003, which was the first toy to sport a ™ after that name. Hasbro successfully registered "Silverstreak" in 2006, but since no new toys sporting that name have been released thus far, there has been no toy that sported an ® after the name yet.

Trailbreaker. Following the release of the original Autobot Car toy in 1984 came a large gap in the release of new "Trailbreaker" toys. The first time the name "Trailbreaker" actually became relevant to Hasbro again was in 2003, when 3H Enterprises reportedly intended to release a redeco of the Robots in Disguise Deluxe X-Brawn toy in a deco based on the original 1984 Trailbreaker toy, that was supposed to be exclusively available at BotCon Europe 2003. However, BotCon Europe 2003 ultimately never happened, and in addition, Hasbro reportedly told 3H Enterprises that they couldn't release a "Trailbreaker" redeco of the RiD X-Brawn toy, as Hasbro themselves were already planning to release such a toy as part of their Universe line. Eventually, however, Hasbro apparently realized that the name "Trailbreaker" was unavailable to them, and thus the toy would ultimately sport an entirely different color scheme than originally intended and was released under the name "Autobot Ratchet" instead.
The next attempt by Hasbro to release a new "Trailbreaker" toy was a redeco of the Robots in Disguise Spychanger Ironhide that would be available as part of a Wal*Mart exclusive Universe two-pack with Ultra Magnus in 2004, sporting a deco directly based on the original 1984 Trailbreaker toy; however, ultimately, the toy was released under the name "Ironhide" again. Following that came a redeco of the Alternators Autobot Hound toy that sported an updated version of the original 1984 Trailbreaker toy's head sculpt; however, ultimately, the toy was given an entirely new color scheme and released as a Decepticon named "Swindle" instead. Another redeco of the Alternators Swindle toy released in 2006 wasn't named "Trailbreaker" either, instead sporting yet another entirely different color scheme and the name "Rollbar". Lastly, a Scout Class toy from the Cybertron line was originally also intended to be named "Trailbreaker", and would have even sported a head sculpt loosely based on the original 1984 Trailbreaker toy; however, the toy would ultimately be released under the name "Overhaul" instead, sporting an entirely different head sculpt than originally planned. A Cybertron Voyager Class toy that is intended to represent an upgraded form of the Overhaul character still sports a name that hints a connection to the originally intended name of the character's original form, namely "Leobreaker".
It's not entirely clear which trademark held by another company actually prevents Hasbro from using the name "Trailbreaker". The primary suspects are "Trailblazer Wagon", registered by a company named Radio Flyer Inc. in 2002, to be used for "Children's wagons", and "Trailbuster", registered by Mattel in 1998 but later cancelled in 2004, to be used for a "toy vehicle". Another theory suggests that it might be the "breaker" part in the name "Trailbreaker" that clashes with other companies' "-breaker" trademarks. However, since Hasbro have since released a Cybertron Voyager Class toy and a Legends of Cybertron toy both named "Leobreaker" in 2005, and a redeco of the Voyager Class toy named "Nemesis Breaker" in 2006, that theory appears to be debunked.
Hasbro trademarked the name "Overhaul" prior to the release of the Cybertron Scout Class toy from 2005, which was the first toy to sport a ™ after that name. Hasbro successfully registered "Overhaul" in 2006, but since no new toys sporting that name have been released thus far, there has been no toy that sported an ® after the name yet.

Overdrive. Following the release of the original Omnibot toy in 1985 came a large gap in the release of new "Overdrive" toys. However, in 1994, Tiger Electronics registered the name "Overdrivers", to be used for "toy vehicles". Tiger would later be bought up by Hasbro in 1998, but ultimately abandoned the "Overdrivers" registration in 2001.
The first and only time thus far the name "Overdrive" became relevant to Hasbro again was in 2004, when Hasbro released an Alternators toy that sported a head sculpt based on the original 1985 Overdrive toy (and which was actually named "Overdrive" in Takara's Binaltech version of the line in Japan). Eventually, however, Hasbro apparently realized that the name "Overdrive" was unavailable to them, and thus the toy was ultimately released under the substitute name "Windcharger", a name originally used for a Mini-Car toy from 1984, instead.
The primary suspect for preventing Hasbro from using the name "Overdrive" is "Overdrive Arena", registered by a company named The Testor Corporation in 2005 (originally filed in 2001), to be used for "Tabletop strategy games incorporating scale models of automobiles".

Mixmaster. Following the release of the original Constructicon toy in 1985 came a large gap in the release of new "Mixmaster" toys. The first new toy after eight years to use the name "Mixmaster" was the Generation 2 re-release of the original 1985 toy released in 1993, which was available in two different color variations. After that came yet another large gap. However, in 1999, Hasbro's new subsidiary Tiger Electronics used the name "Mixmaster" for one of the modes in their "Beat It! Repeat It!" handheld game.
The first and only time thus far the name "Mixmaster" became relevant to Hasbro again in the context of Transformers toys was in 2004, when Hasbro released a set of six KB Toys exclusive Micromaster Constructicons. One of them, whose vehicle mode resembled the original 1985 Mixmaster toy, would have probably been named "Mixmaster". However, Hasbro apparently realized that the name "Mixmaster" was unavailable to them, and thus the Micromaster was ultimately released under the substitute name "Quickmix", a name originally used for a Targetmaster toy from 1988, instead.
The primary suspects for preventing Hasbro from using the name "Mixmaster" are "Mix Master Muttz", which a company named Gary Goddard Entertainment, Inc. attempted to register in 2002 but ultimately abandoned in 2006, to be used for "Toy action figures and playsets, toy vehicles, toy musical instruments, toy recording equipment and board games", and "The Mix Masta' Beatz", which a company named Jakks Pacific, Inc. attempted to register in 2004 but ultimately abandoned in 2006, to be used for "synthetic rubber toys that climb down walls or glass". Gary Goddard Entertainment later successfully registered the term "Mix Master Muttz" in 2007, but this time only to be used for "entertainment services, namely production of a television program for children, and production of motion pictures". If these two were indeed the primary culprits, this could actually mean that the name "Mixmaster" might be currently available to Hasbro again.
Hasbro originally trademarked the name "Mixmaster" prior to the release of the Generation 2 toy from 1993, which was the first and only Transformers toy released by Hasbro to sport a ™ after that name. Hasbro's subsidiary Tiger Electronics attempted to register the name "Mixmaster" in 1999, to be used for a "musical toy", but ultimately abandoned the attempt in 2000.

Powerglide. Following the release of the original Autobot Mini-Vehicle toy in 1985 came a large gap in the release of new "Powerglide" toys. The first time the name "Powerglide" actually became relevant to Hasbro again was in 2006, when Hasbro released a "Classics" redeco of the Legends of Cybertron Jetfire toy in a deco that was originally based on the original 1985 Powerglide toy. However, in 1998, a company named the Regent Sports Corporation had registered the name "Power Glide", to be used for "table top games, namely, air hockey", so Hasbro chose to release the "Classics" Legends toy under the susbtitute name "Fireflight", a name originally used for an Aerialbot toy from 1986, instead.

Slingshot. Following the release of the original Aerialbot toy in 1986 came a large gap in the release of new "Slingshot" toys, although there was a "Classic Aerialbots" reissue of the original 1986 toy which was exclusively available in Europe in 1990, but since the toy wasn't released in the USA, it had no implications on the US trademark.
The first time the name "Slingshot" actually became relevant to Hasbro again following that was in 2005, when Hasbro intended to release a set of six KB Toys exclusive Micromaster Aerialbots (who ultimately wouldn't come out until 2006). Four of the toys sported the names of the other four original 1986 Aerialbots, namely "Air Raid", "Skydive", "Fireflight" and Silverbolt". However, in 2003, Mattel had registered the name "Slingshotz", to be used for "toy vehicles and airplanes, and accessories therefor", so Hasbro chose to release the other two Micromaster Aerialbots under the names "Ro-tor", a name originally used for a redeco of the original 1986 Combaticon Vortex toy released as part of the Robots in Disguise line (later also available in different decos as part of two different Wal*Mart exclusive Ruination giftsets), and "Storm Jet", a name originally used for a redeco of the Beast Machines Deluxe Jetstorm toy released as part of the Robots in Disguise line, and later for an Energon Combat Class toy from 2004 (a Powerlinx Combiner that was part of the Superion Maximus team, later also sold in "Universe" packaging in 2005, this time exclusively available at Big Lots and Tuesday Morning stores), instead.
Hasbro originally trademarked the name "Slingshot" prior to the release of the Generation 2 toy from 1994, which was the first and only toy to sport a ™ after the name.

Outback. Following the release of the original Autobot Mini-Vehicle toy in 1986 came a large gap in the release of new Transformers toys using the name "Outback", although there was a figure from Hasbro's "G.I. Joe" line using the name which was available in 1987, followed by several variations of that figure, with the last one being released in 1993.
The first time the name "Outback" became relevant to Hasbro again in the context of Transformers toys was in 2005, when Fun Publications released a "Timelines" redeco of the Energon Strongarm toy that was exclusively available at BotCon 2005, in a deco that was based on the original 1986 Outback toy. However, by that time, several companies had already registered names that included the term "Outback" in the "toys" category, including the term "Outback Steakhouse" that was registered by a company named OS Asset, Inc. in 2004, to be used for "Toys, namely, toy trucks", and the term "Outback Wildlife", registered by a UK-based individual named John Hanwell in 2001, with a very broad definition of possible uses in the "toys" category, so Hasbro's legal department refused to allow Fun Publications to use that name for a Transformers toy. As a result, the BotCon 2005 exclusive used the substitute name "Fallback" instead.
Hasbro originally trademarked the name "Outback" prior to the release of the second G.I. Joe figure using that name from 1988, which was the first toy to sport a ™ after that name. Hasbro trademarked the name "Fallback" prior to the release of the BotCon 2005 exclusive toy, which was the first and only toy thus far to sport a ™ after that name.

Shrapnel. Following the release of the original Insecticon toy in 1985 came a large gap in the release of new "Shrapnel" toys. The first time the name "Shrapnel" actually became relevant to Hasbro again was in 2007, when Hasbro released a Robot Heroes figure (available as a two-pack with Rodimus) that was based on the original 1985 Shrapnel toy. However, in 2006, a company named Pursuit Marketing, Inc. had registered the name "Shrapnel", to be used for "Products used in the sport of Paintball, namely, paintballs", so Hasbro chose to release the Robot Heroes figure under the former group name "Insecticon", which had first been used as a single toy's name for a Terrorcon toy from the Enegron line in 2004 (later also sold in "Universe" packaging in 2005, this time exclusively available at Family Dollar, Dollar General and Ocean State Job Lot stores), instead.

Runabout. Following the release of the original Battlecharger toy in 1986 came a large gap in the release of new "Runabout" toys. The first and only time thus far the name "Runabout" actually became relevant to Hasbro again was in 2005, when Hasbro released a redeco of the Armada Super-Con Side Swipe toy as part of the Cybertron line, using a head sculpt and a deco both based on the original 1986 Runabout toy (and which was actually named "Runabout" in Takara's Galaxy Force version of the line in Japan). However, in 1998, an individual named Melvin L. Hermsmeyer had registered the name "Runabout", to be used for "hoop and stick sporting equipment, namely a playing hoop and guide stick for guiding the hoop in play", so Hasbro chose to release the Cybertron Deluxe toy under name "Runamuck", previously the name of the original 1986 Runabout toy's fellow Battlecharger, instead.
Even though Melvin Hermsmeyer has since abandoned the registration for "Runabout" in 2005, a company named Morgan Motor Company Limited registered the name "Morgan Runabout" in 2006, with a very broad definition of possible uses in the "Games and toys" category, so this could very well mean that Hasbro's legal department might still consider the name unavailable.

Motormaster. Following the release of the original Stunticon toy in 1986 came a large gap in the release of new "Motormaster" toys, although there was a "Classic Stunticons" reissue of the original 1986 toy which was exclusively available in Europe in 1990, but since the toy was not released in the USA, it had no implications on the US trademark. On the US side of things, a Generation 2 re-release of the original toy was supposed to be released in 1994, but ultimately never came out (and unlike the four Stunticon limbs, G2 Motormaster apparently never even made it to the sample packaging stage).
The first time the name "Motormaster" actually became relevant to Hasbro again following that was in 2006, when Hasbro intended to release a "Classics" redeco of the Legends of Cybertron Optimus Prime toy in a deco based on the original 1986 Motormaster toy (which has thus far only been available from online retailers and specialty stores in 2007). However, in 2004, a company named the Elastic Media Corporation attempted to register the name "Moto Masters", to be used for "toys, namely, scale model toy vehicles and accessories therefore, toy vehicle launchers, track sets, toy aircraft; board games", and even though the registration attempt has not been successful yet, Elastic is already developing a television show using the same name, so Hasbro chose to release the "Classics" Legends toy under name "Menasor", previously the name of the combined form of the original 1986 Stunticon toys, instead. Furthermore, Hasbro also released a redeco of the 6" Titanium Rodimus Prime figure named "Menasor" that was exclusively available at San Diego Comic-Con 2007 and the Hasbro Toy Shop website, with the name "Motormaster" actually being used in the official bio for the toy.
Hasbro originally trademarked the name "Motormaster" prior to the intended release of the Generation 2 toy in 1994 (referred to as "Motormaster™" on the packaging for the four G2 Stunticon limbs Dead End, Breakdown, Drag Strip and Wildrider), which ultimately never came out.

Hook. Following the release of the original Constructicon toy in 1985 came a large gap in the release of new "Hook" toys. The first new toy after eight years to use the name "Hook" was the Generation 2 re-release of the original 1985 toy released in 1993, which was available in two different color variations. After that came yet another large gap.
The first time the name "Hook" actually became relevant to Hasbro again following that was in 2004, when Hasbro released a set of six KB Toys exclusive Micromaster Constructicons. One of them, whose vehicle mode resembled the original 1985 Hook toy, would have probably been named "Hook". However, by that time, the name "Hook" had already been registered by other companies in a large number of combinations and in a large variety of fields, including the term "Hook-Ups", originally registered by a company named the Shadowdance Corporation in 2002, to be used for "Dolls, namely, action figures", with the onwership of the term later being transferred to a company named Blitz Distribution, Inc., so Hasbro's legal department considered the name unavailable. Thus, the Micromaster was ultimately released under the substitute name "Hightower", a name originally used for a Robots in Disguise Deluxe toy (a member of the Construction Team that could merge to form Landfill, which was later also available in a different deco as a Wal*Mart exclusive Landfill giftset), instead. The same name was later also used for a Universe redeco of the Robots in Disguise Hightower toy that was available as a Target exclusive two-pack with Long Haul and a redeco of the Energon Duststorm/Wideload sculpt that was available as part of the Wal*Mart exclusive "Classics" Constructicon Devastator giftset.
Curiously enough, Fun Fublications released redecos of the Cybertron Giant Planet Mini-Con Team (Deepdive, Longarm and Overcast) that were available with the Official Transformers Collectors' Club exclusive "Timelines" Astrotrain toy from 2007 (a redeco of the Armada Giga-Con Jetfire toy), with the three Mini-Cons being named "Astro-Hook", "Astro-Line" and "Astro-Sinker", each of them sporting a ™ after the name on the packaging. It's unclear how Fun Publications could get the name "Astro-Hook" when the name "Hook" had previously been unavailable to Hasbro in any form whatsoever.
Hasbro originally trademarked the name "Hook" prior to the release of the Generation 2 toy from 1993, which was the first and only Transformers toy released by Hasbro to sport a ™ after that name. Hasbro trademarked the name "Hightower" prior to the release of the Robots in Disguise Deluxe from 2001, which was the first toy to sport a ™ after that name. Hasbro attempted to register the name "Hightower" in 2004, but ultimately abandoned the attempt in 2005. Hasbro apparently trademarked the name "Astro-Hook" prior to the release of the Collectors' Club exclusive Astrotrain toy form 2007, which was the first and only toy thus far to sport a ™ after that name on the packaging.

HiQ. Following the release of the original toy in 1988 (the Nebulan companion of the Powermaster Optimus Prime toy) came a large gap in the release of new "HiQ" toys. The first and only time thus far the name "HiQ" actually became relevant to Hasbro again was in 2003, when Hasbro released a Commemorative Series II reissue of the Powermaster Optimus Prime toy. However, in 2001, a Taiwan-based company named Dah Yang Toy Industrial Co., Ltd. had registered the name "Hi-Q the Inteli-Bot", to be used for "toys, namely, battery operated robots", so Hasbro chose to release the companion figure for the Powermaster Optimus Prime under the substitute name "Ginrai", originally Takara's name for the HiQ figure as well as for the Powermaster Optimus Prime toy itself in Japan, instead, referred to as "Ginrai™" both on the packaging and in the instructions. Oddly enough, Ginrai was the only substitute name for an existing Transformers character actually used by Dreamwave Productions for their More Than Meets the Eye guide books, which otherwise favored the respective toys' original names.
Hasbro trademarked the name "Ginrai" prior to the release of the Commemorative Series reissue of the Powermaster Optimus Prime toy, which was the first and only toy thus far to sport a ™ after that name. Thus far, Hasbro have not attempted to register the name.
