You might have seen this coming for a mile or so but I go with Juggy's power of being virtually unstoppable once he decides to move in a certain direction.
You have many superhumanly strong characters in the MU but Juggy is the only one who is near unstoppable if he wishes to be so.
I have always been fascinated by that and I love that power!
