Tim is the owner of the dojo. He is often nervous, and even though he owns a place of training, the marowak prefers peace over fighting.
Tim had gotten into a fight with a dusknoir on the team's second day at Treasure Town. Although he was trying to settle things peacefully, the dusknoir apparently felt lied to. He attacked, yet the team fended him off, along with the sudden aide of the strange grovyle.
After the team helped Tim, he explained what the dusknoir was after. A secret the town vowed to keep hidden, about the incident years ago.
