I personally don't care for the Mini-Cons... it's the main 'bots that interest me.

Speaking of Mini-Cons, the Autobots' Mini-Cons' names are transliterated in this thread (and possibly other Anglophone sources) as:
Ōpī, Bītsū, Shieru and Arue. These names are actually kinda like "codes" for the names of their Autobot partners, and should be transliterated thusly:

Ōpī = OP
Bītsū = B2 (because Bumblebee is AM02)
Shieru = CL
Arue = RA

The Decepticon Mini-Cons' names seem to be play-on-words based on their bestial robot modes.
e.g. Megatron's is Gora, and the Japanese word for gorilla is "Gorira." Soundwave's Mini-Con is Zori and the Japanese word for scorpion is "Sasori". I'm not sure about Baro (Skywarp's MiniCon) or Jita (Terrorcon Cliffjumper's Mini-Con) cos I have no idea what Baro's robot mode is mean to be, and Jita's robot mode resembles ROTF Ravage's robot mode... but the Japanese word for jaguar is "Jagaa" (which was G1 Ravage's JP name). <shrug>

Is it just me, or does OP resemble G1 Shockwave?
