Far from the greatest in No More Heroes history, Mr. Black Hole is a decent boss.
We learn that his service to Fu is mostly out of fear. He is afraid of Travis Touchdown far less, so they start to battle anyway.
Since it’s the first boss battle of the game, things are rather simple.
Just hit him with the laser sword while avoiding black holes on the ground.
Phase 2 of the battle takes you to space.
You get to have fun being the pilot of a Gundam-like space battle machine.
And you get the satisfying kill. He’s a bit too easy.
