Ripjak is a fictional comic book character from an alternate future Marvel Comics universe and appears in the Guardians of the Galaxy comic book series.

Dubbed the Interplanetary Serial Killer by the media, Ripjak was a Martian antagonist, and later ally, of the Guardians of the Galaxy in the Earth-691 timeline of the Marvel Universe. It was later revealed that Ripjak was not the killer he was believed to be but rather an agent of mercy. He came to planets that had already been infected by the being known as Bubonicus and then wiped them out to prevent the contagions from spreading and end the suffering of those living there

Ripjak wore an artificial exoskeleton and had enhanced abilities from a blood transfusion with Spider-Man.

Ripjak has not been a contender in any CBUB matches.
