Iron Maiden was an original member of Coon and Friends. He made his debut appearance in the Season Fourteen episode, "Coon 2: Hindsight". He has retired after the conclusion of the superhero arc, the reason is unknown.
In the superhero arc, Timmy is shown to be a part of Coon and Friends under the name Iron Maiden. In the episode "Coon vs. Coon & Friends", it is revealed that his (imaginary) super power is indestructibility. Iron Maiden can only say "Timmy!" and introduces himself as such in "Mysterion Rises". The name Iron Maiden comes from the medieval torture device that resembles a sarcophagus filled with spikes.
