Gaz all that work you made me do for the achievement, and he's the worst Team-up in the game. His wimpy melee strikes do no damage. Neither does that chunk of concrete he (very rarely) throws. And his tankiness? He's so squishy he might as well be non-existent. And you can't even use his away benefits! +1% power range? That's like nothing.
This guy's even worse than the S.H.I.E.L.D. Agent. I wish I could get a refund on all the time I spent unlocking him (took me like 8 hours!) but instead I'm just going to pretend he never existed.
I mean look, even his model is terrible!:

April Fools! The joke is that it's a day late! =))
