Okay, so I'm watching Dressrosa. I'm at the part where Bartolomeo and Bellamy are fighting in the Colosseum. Is it me or did Luffy come up with Boundman right there because of Bellamy's springs? The compression on Boundman's attacks look so much like Bellamy's spring attacks.
If so then I wonder what his base form for Gear Fourth is. Is it Tankman or another third form we've yet to see?
