"Otis is a latecomer to the Pokémon TCG, but after joining up with Daniel and Rika, he's become a force to be reckoned with. He's a man of few words, but he regularly attends football games and his backpack is usually loaded with books on popular science and the statistical analysis of sports."
In City Championships
Officially, Otis uses a Darkness and Grass deck in the City Championships. However at the moment a glitch in the system causes him to use a Fighting and Grass deck during gameplay.
