From another thread:
Pizarro is Blackbeard's number three.
Is not mentioned here.
Was notably the only prisoner alongside Shiryu without the striped uniform.
Pizarro has less hype than Shiryu but more than the other prison recruits. Add to his former North Blue royalty, that's as far as a Sanji opponent gets.
To contrast with Sanji fighting with legs only, Pizarro's metal arms imply he fights with his arms.
