From Bulbapedia, the community-driven Pokémon encyclopedia.
Glenn (Japanese: グレン Glenn) is one of the characters of the day in Battling the Bully!. He is a friend of both Mick and Sean. Glenn loves to have Pokémon battles despite not owning any Pokémon of his own and having little knowledge about them. He could be described as both bossy and intimidating. When Sean brought over his father's Pokémon to show off, Glenn immediately would snatch them from him. He believed that the most important thing about battling was winning and sometimes forced Sean to purposely lose battles with him.
Once Mick had shown Glenn the Pikachu he claimed he got from his father, he wanted to have a battle with it and told Sean to get stronger Pokémon from his father, while he searched for Mick and Pikachu, who had run off. Once he found them, he brought them back to the yard, where Sean gave him his father's Scolipede and Seismitoad. He planned on using both of them against Pikachu, but Sean stated that it would not be fair and told Mick to use two as well. A Krokorok wearing sunglasses volunteered to be Pikachu's partner, and the battle commenced. During the entire battle, Sean would try to give Glenn advice, which he did not follow out of annoyance. Because of that, he lost the battle to Mick. Angered by this, he accused Mick of purposely trying to humiliate him and nearly punched him when Ash intervened. Sean then said that he did not want to be Glenn's friend anymore, which helped him realize that his behavior was less than favorable.
Feeling bad that Scolipede and Seismitoad got hurt, he fed them some of Cilan's special food to help them heal. He later apologized to Mick and Sean and realized that having a fun battle was more important than winning.
| Glenn borrowed Patrat from Sean's father and used it in a battle against Sean. Though it had won the battle, according to Glenn, it was still too tired to move.
Patrat's only known move is Tackle.
