Ooh, interesting idea. Does he still use his legs to walk, or does he walk or swing around with his arms?

He still uses them to walk. There are special gyros implanted in what used to be his ankles. These allow him balance and flexibility. Essentially allowing him to balance on any fine point like a stilt-walker. The blades themselves are interchangeable as well, So depending on his mood he can balance on Katanas, Bastard swords, broad swords, Daggers, Bamboo poles, spears, anything. After having the legs replaced he learned how to use 4 swords. One in each arm..and both 'feet'. So if he wants to show off an "axe kick"...well...he can use actual battle-axes to accomplish this :p
