TMS Entertainment

TMS Entertainment, Ltd. (株式会社トムス エンタテインメント, Kabushiki-gaisha Tomusu Entateinmento), formerly known as Tokyo Movie Shinsha (東京ムービー新社, Tōkyō Mūbī Shinsha), is a Japanese animation studio currently owned by Sega Holdings Co., Ltd. Some of their domestic productions include nearly every Lupin III series and movie since the '70s, Sonic X, The New Adventures of Gigantor, Bakugan, Detective Conan, Space Cobra and five decades worth of other stuff.
As both TMS and their sub-studio Telecom, they have done a LOT of work for foreign animation, including the Hasbro series Visionaries, Inspector Gadget, The Real Ghostbusters, Bionic Six, Mighty Orbots, Tiny Toon Adventures, Animaniacs, Batman the Animated Series, Justice League: Doom, the 1994 Spider-Man cartoon, and you wouldn't believe how much more.
It is widely believed in the Transformers fandom that TMS animated the episode "Call of the Primitives", although there is no evidence to support this beyond the fact that TMS was occasionally outsourced by Sunbow Productions in the mid-80s. Part of the theory could be due to an interview with a staff member from the Sega Saturn game Burning Rangers, who mentions TMS's invovlement with the original series[1].
In terms of cited work on Transformers, TMS provided background artwork for two episodes of Transformers: Cybertron through the Telecom unit.
