There have been characters of various ethicities incorporated into Transformers over the years: Spanish (G1 Cosmos), Australian (AEC Jetfire), Afro-American (Jazz and Blaster), Italian (Dino), British (the DOTM Wreckers), Russian (TFA Jetstorm), French (AEC Mudflap), German (TFA Blitzwing), Japanese (Drift) and even Chinese (the video-game fembots in TF PRIME). So it should be okay to feature an Indian Transformer. We've had Apu from THE SIMPSONS, Raj from THE BIG BANG THEORY and other such Indian characters appearing in TV shows recently, so it can work. The question is would it be acceptable? Is there a character (either previously done before, or an original one) for which the Indian ethnicity would fit, and in a manner that Indians would not find perhaps insulting?
