Which people played a pivotal part in the creation of the Transformers as we know them today? Let's see: Kouzin Ohno (name sometimes misinterpreted as "Mitsuhito Oono") was by far the most prolific of the Diaclone designers, being primarily responsible for most of the original designs that became the Autobot Cars (Sunstreaker, Hound, Bluestreak, Skids, Ironhide, Jazz, Inferno, Mirage, Sideswipe, Trailbreaker), the Omnibots, the Decepticon Jets (the original Starscream/Thundercracker/Skywarp mold; the Dirge/Ramjet/Thrust redesigns were done by Takayoshi Doi), the Dinobots, the Trainbots, the Constructicons and the Decepticon Triple Changers. He also continued to design original Transformers for Hasbro and Takara such as Galvatron, Metroplex and Fortress Maximus. He's also listed in the Transformer Station section of the opening credits for Victory, so it would seem that he did designs for that series as well. An interview with him can be found in the the Japanese "Transformers: Generations" book. Hideaki Yoke was a Diaclone and Microman designer (Perceptor, Gears, Swerve, Hubcap, Tailgate, Outback, Pipes, the Battlechargers) and also acted as Hasbro's Takara liaison in the first months of the Hasbro/Takara partnership. BotCon 2005 panel report Other toy designers were: Hiroyuki Obara (Optimus Prime, Ultra Magnus, Wheeljack, Blaster, Tracks), Akio Kitamura (Beachcomber, Cosmos, Seaspray, Warpath), Masaki Maruyama (Powerglide), Takashi Matsuda (Megatron, Topspin, the Insecticons, all the initial Autobot and Decepticon cassettes except for the combiners), Satoshi Koizumi (Soundwave) and, for the non-Takara molds, Yukimitsu Matsushiro (Jetfire, Roadbuster). The patent pages, Transformers patent via the European patent office Nobuyuki Okude (Takara's later vice president, and eventually president and CEO as of 2005) was also part of Takara's Diaclone design team and overseeing the changes done to the toys for their release on the Western market. Interview Henry Orenstein convinced Hasbro to release the toys to the US market and coined the name "Transformers". Link 1, Link 2, BotCon 2004 panel (name misremembered as "Normanstein") Was this before or after Hasbro discovered the toys at Tokyo Toy Fair 1983? Hasbro's then marketing vice president Bob Prupis assigned Marvel to come up with a backstory. BotCon 2004 panel Marvel Comics' Jim Shooter came up with a rough story concept, which was then expanded by Dennis O'Neil, who also coined a few names, including "Optimus Prime". Bob Budiansky then came up with characterizations and names for the rest of the characters, including "Megatron". Interview 1, interview 2 Syouhei Kohara (presumably an artist at Toei) created at least some of the the animation models for the cartoon characters; Floro Dery then simplified them (such as removing Optimus Prime's wheels in robot mode, and changing Megatron's head to more closely match his toy). Interview 1, interview 2 Thanks to JonT for Hideaki Yoke and Kouzin Ohno, and to Buster Darkwings for the correct spelling of some Japanese names, and other additional information.
