As Hurstcon said, Encore would be the way to go Bidoofdude, plus you'll get a face for him.
Genesis is only a couple of inches taller measuring head to head, less so if you count the wings. It's just the sheer size of those forearms that impresses me the most.

just had to add one or two more pics in the "come at me bro" stance just for size comparison.
(plus i found out he has 6 little rotating turrets, 4 on the hips, 2 on the wings.
a nice touch)
