Which 5* should i take to r4?!

All champs are unduped. I currently have duped r4 Red Hulk, Starlord and Drax. Almost ready for my next champ. Would like a good AW defender.

Voted for Ultron because he is one of the most annoying def in AW.
But, Hype is very good at both roles.
IMIW is the worst, but, dupped. Undupped he 's manageable.
The others, I don't mind facing them.
