Antonio Castillo Jr. has over 30 professional mixed martial arts fights to his name and a few boxing matches as well.

He has faced high level opponents like the UFC’s David Onama and the former XFC champ, Nick Newall among others.

Castillo brings a well-rounded game when he toes the line and his willingness to go out on his shield makes for an entertaining performance win or lose. The Ohio native knuckles up for the first time in the BKFC against Mike Hernandez at BKFC Fight Night Michigan on November 1, 2025.
