[Nemesis*Prime]

The Marvel Universe stuff is great and the fact that Hasbro is even adding giant sized figures (like a SENTINEL) is awesome. Blade, Moon Knight, Fury, and Firestar are my favorites from the selection shown.
As for voting for the next 5 MU characters, from the 70 Marvel is giving us, there are just so many great choices it's hard to pick. But here are my 5 anyway:

Silver Sable
Psylocke
Mystique
Madame Hydra
Lady Bullseye

I voted for all female characters since there's never enough made.
