Boo Jack

Boo Jack
Appears in the second movie, one of the Trump Siblings Pirates. He fights with a weapon called the Toge Toge Armor/Spike Spike Armor, in which he can emit spikes on his coat and launch them at people as well as become a giant rolling spiked ball himself.

Once Sanji gets his shoes back however, he easily beats Boo Jack into submission.
