Baseball Cap is a character in Go, Battle Monster! who joins the game when there's an extra card.  He doesn't win first, as he is beaten by Chocolatey because she believed in her card.

He likes being called "ExtremeBattleMonsterLord_66.7".


  • "Oh, ooh!  I wanna join!"
  • "I'm Baseball Cap, but you can call me ExtremeBattleMonsterLord_66.7 and I'm the master of this card game!"
  • "ExtremeBattleMonsterLord_66.7!!"
  • "Yaees... YAAAEEES..."
  • "What?!  How did you defeat me?"


At some point in the video his mouth is gone.
