id bet money this guys pattern would be:
1. rotate wheel body and slash and shoot in various angles x 4
2. rush towards you fast but retreat slowly X 1 (this is when its most vulnerable to attacks)
3. the throwing of spinning knives in an arc
I could beat it. These things always ahve a pattern, you let it run around and dodge the attacks and wait til you figure out the pattern and then you'll know when it's most vulnerable, when it turns it's back etc.
That's when you use your special moves, bombs, whatehaveyou. Just don't get too excited.
