Kurt Ryder was born a metamutant. The details of his parentage and early life are thus far unknown, up until his short stint as a circus acrobat. He was soon kicked out of the circus for looking and smelling too "freakish". When the "new blood" members of the JLA headed to New Jersey to investigate reports of a strange creature living in the wild, they discovered Kurt Ryder. He took the name of Nightcreeper as he joined the New Blood of the Judgment League Avengers.[1]

Like the rest of the New Blood members, who were actually brought together secretly by Mister X, Nightcreeper joined the Justice League X-Men as a founding member.[2]

A love triangle developed between Nightcreeper, Angelhawk and Kokoro. Nightcreeper and Angelhawk had both fallen in love with Kokoro, which was causing problems amongst the team.[3]

When the Armageddon Agenda arrived, Nightcreeper was among the metamutants who were imprisoned by the JLA. He also was one of the original members of the new JLX team, which was assembled by Wonder Woman when Fin Fang Flame attacked the JLA.[3]


Nightcreeper can teleport, regenerate from severe injuries, and has superhuman strength, speed, agility & stamina.
