From the top of my head i'd play him like this I think. Someone else come up with a point score
Tony "Can build it in a cave with just a screwdriver" Stark
WS BS S T W I A Morale AS/IS 4 4 4 4 3 4 2 10 2+/4+
-counts as Jump--infantry -equipped with 2 powerfists that double his strength but don't count as unyieldy and don't reduce I to 1 -equipped with a Plasmagun (his usual blasts) -equipped with a one use conversion-beam (the fancy red beam cutter from the end of II ) -May be taken as a HQ choice -all repair vehicle rolls might be rerolled
"I played with your toys a bit" Throw a D6 - on 5+ upgrade all Dreadnoughts to venerable Dreadnoughts for free. That's what happens if you leave him alone with a screwdriver.
"Red unz go fasta" This suit was an Ork trakk in it's former life - or at least the paintjob was. Add +1 to the maximum range in the movement phase.
I was thinking about this crossover the other day... Other Marvel characters in the grim dark millenia : Deadpool as a heretic Evesor assassin Black Widow as a Dark Eldar whych Thor as a Space Wolf priest Doctor Doom as a Necron overlord Nick Fury as an Inquisitor Lord
Yeah, So I was thinkin´on it too. My idea was to use just imperial agents, 2 imperial assassins, a surviving astartes from the time of the Heresy, with an modified DNA to be more almost as strong as a primarch, a young space wolf with psychic powers who claims to be the incarnation of Russ... even an space marine modified with ork DNA to create something like Hulk. (maybe with an ogryn body as base)
