Well, I know some are actually Autobots, but you get my drift. Duo Battletrap Flywheels Sky-lynx (am I right in thinking he is?) Overlord Trio Magnatron Tidal Wave Are there any more that I've missed?
Sky Lynx sort of is? he's kinda weird, because each half can do its own thing, as himself. i think the definition of a duo/triocon/bot would be a bot that separates into multiple alt modes that they themselves do not have a robot mode.
Omega Supreme sure is something. Tank, missile and...a whole lotta track...and some yellow clips. I wonder if he fits into the "duocon" category or the "I'm a mess o' parts robot" category.
