I've been to my fair share of Comi-cons. I understand that not everybody can blow ten grand on a fully-functional Patlabor costume, and that's cool. I dont expect you to. I do, however, expect more than whatever the hell this is.
I'm not really sure how he could get bitten through all that armour, but it appears Tony Stark is the newest member of the gory undead. Zombie costume: boring. Iron Man costume: boring. Zombie Iron Man costume: sure!
