He appeared to be one of the more welcoming members of the council. When Phineas Phage joins the council to replace Councilman 4, he insists they have a form of celebration to commemorate the new event.
Little is known about Steppenwolf's past and background. He is a werewolf-themed supervillain and appears to be one of the older members of the group alongside Dr. Z, Boggles the Clue Clown, Dragoon, and Red Mantle. He owns a car similar to that owned by the family in The Munsters. After Councilman 4 (Boggles the Clue Clown) passes away, he's replaced by Dr. Phineas Phage. Steppenwolf seemed excited over the new event, stating it was the first time in 15 years since the group had a new member. He insisted, along with Dr. Z, that they celebrate the moment and welcome the new member to the team. Though the Sovereign rebuffs the idea as he insisted that the councilmen keep their identities hidden, the group decided to do it anyway.
He then drove 10, Dr. Z, 4/Phineas Phage, Dragoon, and Red Mantle to Don Hell's nightclub. He and Councilman 10 may have a friendship, as he drives him to the meetings, as it was shown in All This and Gargantua-2.
He would appear for the last time in "All This and Gargantua-2", getting called by the Sovereign for an important meeting. Reluctantly he was late, because Councilman 10 wanted some Chinese food. Unknown to them, a car bomb had been placed in Steppenwolf's car. The two were killed instantly when the bomb went off.
- Given his age, it is possible he's one of the older villians who probably arched in Jonas Venture Sr.’s time.
