If I'm not wrong, most if not all the Dinobots have been KO-ed. Definitely something to watch out for because sometimes, even the sellers themselves believe them to be the real thing.

A seller was trying to sell me a KO MIB Prime for $250 at CSC. I said, you do know that is a bootleg yes? And he looked and sounded like he had no idea it was fake (or maybe he's faking, who knows).
