I wouldn't say that I've followed the Avengers a whole lot. I really started picking it up with the whole Avengers Disassembled event but then started picking up the trades of the older storylines soon after.
I'm still think that Ultron is an A-Lister. How bout this though IL, name a villain that's a true Avengers foe. Someone who isn't really pinned down to one certain hero/heroes as an arch-enemy.
Ok, cats got my tongue and you win, can't think of anyone believe me I'm trying.
