Powers and Abilities
Rook uses various Plumber weapons and technology, such as the Proto-Tool to battle. It has also been shown that he has some acrobatic skills. He also has very durable armor called Proto-Tech Armor.

Personality
When Rook first met Ben in The More Things Change: Part 1, he was respectful of Ben, mentioning that he heard all about him in the Plumbers Academy. Unlike Ben, Rook is more stoic and prefers to think before acting. He seems to treat Ben more like a superior instead of a friend/partner as he usually adresses him as 'sir'. While he is very intelligent, his lack of experience can make him somewhat naive and immune to most of Ben's jokes.

Ben 10: Omniverse
He is a co-op partner in the game who travels in time to help both Bens.
