Al the Sloth
Oh definite one of the best. He's probably one of my favorites so far and the only one as ruthless as him was Arlong and Croc would demolish Arlong. I thought the same thing if you though in Ace. He'd turn Croc into glass for Luffy to shatter. I wish we saw more of him before he died. He was one of the coolest characters. Also I forgot about the explosion. Did it ever say how he got away?
Yea, Arlong wouldn't realize that water is Crocodile's weakness and he'd have the water sucked out of him in no time flat. Plus Crocodile is so tall. He's 8'4. I'd be intimidated just standing near him. xD
Ace would've made the arc way to easy for Luffy.
Nope. It's never really explained how Pell magically survived it. I wish it would though, it kills me to this day, to think he could survive a bomb meant to kill thousands at once.
