*whimper*
i can't narrow it down. Flint and Footloose were the first two i got*. and i loved Flint in the UK comics, he was so badass and not the cocky snot the US version was.
Snake Eyes v2 however is my favourite version of one of my favourite characters...
then there's Airtight. for some reason i really loved that figure as a kid.
and then we've got Ace, who flies my favourite vehicle, the Skystriker....
and on the Cobra side, the Crimson Guard is just fragging cool as ice...
but, since buying them, i've grown to love the v1 Alley and Night Vipers...
*not including the O-ring articulated AF figures or the Grunt figure who was a mail-away in AF series 3 and i got instead of the Commander figure i applied for, because i applied at the end of the Commander offer and got Grunt instead, and he was supposed to be a generic AF infantryman... i never even knew who he was until i got on the net, as he was sent in a bag, with no bio card or anything and for whatever reason, i never bought any of AF S3 as a kid.
