Frederick DeLamb is the son of a Markovian government official who acted as a puppet ruler by the Nazis during World War II and was killed by a mob.

Years later, Frederick, taking the name Baron Bedlam, kills Markovian king Viktor and seizes the throne.

Prince Brion Markov works with Helga Jace to give himself superpowers and battle Bedlam.

He temporarily possessed earth-manipulating abilities similar to Geo-Force, but lost them due to not being Markovian royalty.

[5] Baron Bedlam appears in Young Justice: Outsiders, voiced by Nolan North.
