Did a quick swap of Cyke's stubby lower arms with some Deadpool lowers (gotta love that $5.99 sale at Target a while back.) Makes all the difference. I can even overlook his lack of ankles now.

Mine stands just fine on his own - even with the eye-beam inserted. Nova's made out of a Johnny Storm for a size comparison:

Cyke's got pretty much the best superhero torso I've seen yet - I plan on getting a few and using the torso for customs (The Flash comes to mind). The mid-torso joint is nearly invisible and really well sculpted.
Still haven't been successful elongating Iceman, though -- his problem is his lower torso - it's WAY tiny. If I can find a replacement (Deadpool's is a little too big), I can fix Bobby's height issue and have him wearing a surfer-style "onesie" so he can still have clear arms & legs.
