Rook appears as he does in Omniverse. His Proto-Tech armor is the same, though its origins can vary.
Dimension 1 (John Smith 10)
This Rook appears in Ancient Greece, being a son of Hephaestus and a Revonnahgander. As of alien origin, he is shunned from all society. He stays in his lab, building advance tech, including an automaton lion named Leo. When John Smith meets him, he instantly accepts him, allowing him to travel with him. Because of this, he becomes loyal to John, following him everywhere.
When following John into the Sea of Monsters to save Eirene, he is thrown off the ship. He finds his way into Daedalus' labyrinth, thanks to help from his father. He rescues John and Eirene by using the tunnels, and meets Daedalus, who had made himself immortal. Rook joins the army of Athens as they fight Kronos' army as they attack Mt. Olympus. Despite discrimination against him, he still fights. He is upset upon John leaving back to his own time.
After John left, Rook made his way back to the Labyrinth and finds Daedalus. He turns himself into an automaton, allowing him to live for another 2000 years. He's recruited by Professor Paradox to fight against Gaia, who has been fighting to awaken for millennia. Rook fights alone underground for all that time. He is reunited with John as they come together to fight, and defeats Ssserpent. He stays down in the caves as John fights Gaia above the surface. However, he goes up and sacrifices himself to save John.
With the universe being shattered, he is revived along with many other characters, including the Greek gods. He joins his father Hephaestus in his workshop, when John finds them. He joins up with John without a second thought.
