Jotar Kuj

"'you know what else is a massive L, my cock' - Jotar Kuj" Jotar Kuj is a major ally in the fourth season of the series, World War.

Jotar Kuj is the second universe counterpart to Larry Butz. He is also based on the fictional character Jotaro Kujo. He appears as the cellmate of Not Racist, who he befriends. He then reveals that he is the Penis Man and breaks the two out of prison using Star Platinum. He meets and befriends Keller and Giles, and kills Sal Manella for them. He accompanies them on their journey to defeat Gamin, and infiltrates Gamin's Time Dilation Field, killing him. However, Gamin's Anthropic Principle revives him. Jotar, Keller, Atmey, and Giles eventually triumph over Gamin.

Star Platinum
As the Penis Man, Jotar is able to summon a humanoid figure he calls Star Platinum. Its primary ability is to initiate an incredibly strong barrage of punches, which he uses to kill Manella, his stans, and Gamin, and to break out of prison. However, Jotar also eventually figures out that Star Platinum allows him to be unaffected by Gamin's ability to stop time, though Jotar can't stop time himself.
