Extendo-legs are over-rated. Jump jets are where it's at.
Bunnie has used the mighty claw much earlier in the comic, way, way back in Page 31. Another inspiration from a BattleTech video game product, the Battle Armor from MechAssault 2: Lone Wolf was one of the coolest things I had seen that wasn't a 'Mech from a BattleTech product. Along with a powerful mortar and jump jets, there was the badass claw that not only punched a hole in the wall (or building), but allowed you to recharge your jets and get a HIGH vantage point. Or, in this page's case, sidestep out of the way.
