Captain Carrot

Captain Carrot, an analog of Superman, was in charge of collecting superheroes from across the Multiverse after Thunderer activated the alarm in the House of Heroes.

He greeted Superman of Earth 23, saying that they had met before, and led him to the central room of the House of Heroes. He embarked on a mission, alongside other multiversal heroes, to rescue Nix Uotan, the Last Monitor.
