4-pack Mr. Fantastic Handswap
 

It was bugging me. Mr.Fantastic's greatest strength is his brain. dude needs two "open" hands to work computerpanels and fix stuff/hold macguffins he builds.

The 4-pack Mr. Fantastic is a wonderful figure, but his right hand is balled up into a fist!

thankfully, I've found a suitable replacement. The right hand from a Tron: Legacy "Quorra" figure. now the man can get shit done properly. Here he is holding a GI Joe suitcase full of some nanomachine thing.

The peg on Quorra's hand is kinda short, but it's thick enough that it holds in place as long as you don't have him holding something 3x his weight.
