I don't know, actually. I've never read any of the comics, so I cannot say...the cartoons though, aren't that violent at all. I'm only familiar with Prime and the latest series, and I know I watched the OG version growing up, so it can't have been that bad. Prime especially is just an excellent show. Living metal aliens come from a dying war-torn world to earth, because their ship--the last colony ship of their world, called the Ark--crashes. One the one hand, you've go the Autobots; honest, heroic, compassionate, honorable heroes.
On the other, Decepticons; power-hungry megalomaniacal killing machines who sought to rule Cybertron by force and, in the process, destroyed it.
Avoid the movies like the plague, however. Just...seriously, they are blank-faced stupid. O_o I love Transformers, and I refuse to watch the movies. XD
Tater tots or french fries?
