Titus is a Pokémon Trainer that qualified for the Kalos League and was matched up against
Ash Ketchum in the first round. He almost won the match by default as
Ash Ketchum almost didn't arrive on time before the referee called the match.
Most of the battle was not showcased but
Ash Ketchum defeated
Titus to eliminate him from the competition. As the first round was a 3-on-3 battle, he has at least 2 other Pokémon that were in the match but were not shown at all.
