I like TC. Shame his corpse got mutated into Scourge by Unicron.
If he did come out of the influence of the 'Cons, I hope he wouldn't end up as an Autobot. They are too goody-goody for my tastes. Mostly the spoiledge comes from the some of the humans they hang around with.
I would like to think he starts his own faction, neither Autobot nor Decepticon but in a grey area. This faction would be composed of either mostly 'bots who are not in total agreement with their respective factions' ideals and left, or mostly of Seekers, the numerous 'drones' or grunts that have defected from Meg's army but are not Autobots.
Thundercracker is sexy. I love his name especially.
