Alright my math is a little off, with SW wave 3 giving us a villian explosion it is just easier to see them now. I agree we need more villians. Thankfully marvel is a lot more interconnected then DC you get a lot of bad guys who fight more than one hero but some heros rogues gallery aren't present at all.
Also I counted 15 diffrent villians, 16 with the double hand ninja.
Your right! I wonder who I missed the first time I counted.

So that's more like 1 for 3.

A little better.
It seems there were alot more one on one nemesis in DC comics, where as Marvel was either whole teams versus one villain. The Avengers were always having problems with one enemy at a time it seemed.

Ultron, Doom, Magneto, Task Master, Absorbing Man, etc. The X-Men seemed to battle groups of other characters as well as one on one battles. Thinking about it, I can see why Hasbro might be torn when deciding who to release next. Marvel fans love full team rosters, and lets face it, they are the best teams ever made in comic history, but they also love the villains. I have to say. I think although I'd like to see more core villains introduced early on, I would much prefer to see a full team roster built. With the way things look for the waves this year, it would seem Hasbro is thinking of isolating particular groups per wave. The X-men wave is awesome. Then we have the next wave due out, which is more of a loner wave. Hopefully Hasbro will do a few team waves then give us a pure villain wave. I think folks would eat them up quicker and more easily that way.
X-men wave, Avengers wave, Sinister Six, New Warriors, Inhumans, X villains, etc....
