Just for whatever you want to talk about for this version.

I'm in the mood to talk about what was reused from MUA1. Now some might complain that they expected new models and anims, but I'm guessing MUA2 only came to these systems because they saw development would be fairly inexpensive. Remember MUA1 reused lots of anims and models from XML2, which in turn reused lots of stuff from XML1.
1. SHIELD soldier is definitely from MUA1
2. Torch's animation is reused from MUA1, and it looks like Songbird may be built off of a female MUA1 character
3. Hulk anim and effect reused
4. Deadpool's idle stance reused, Thor's menu exit anim now used for a power
5. Psylocke looks to be built from a MUA1 female as well
6. Cap and Storm's anims reused
7. Cyclops' animation and effect reused, and possibly a reused XML2 Astonishing Cyclops model
On a different note, I still don't understand why Blade looks like a white American biker...
