is a Pokémon Trainer that traveled in the Kalos region with his older brother Nico
. He had been training with his brother in preparation for his first battle at the Battle Chateau. They are a hip hop duo and speak with a hip-hop dialect which seems to annoy Serena
who thought they were rappers.
In his debut Battle Chateau match, he faced Ash Ketchum
. Unfortuantely for him, Pikachu
had a super effective type advantage over Chester's Fletchling
and also had a lot more battle experience so it wasn't long until Pikachu
was able to defeat it. Ash Ketchum
was awarded the title of Baron for winning the match. Chester
was polite and little frustrated but he congratulated Ash Ketchum
and looked forward to his next match by vowing to train harder with his brother.
