Bede

Bede is a character who appears in one of the player's rivals in Pokémon Sword and Shield. He is one of the people who once received endorsement from Chairman Rose but later had his Gym Challenger status revoked. Opal recruited him to be her successor soon after. He mostly specializes in Psychic types, but changed to Fairy types after successing Opal's position.

Bede is extremely prideful about his ability as a skilled Pokémon Trainer and his endorsement from Chairman Rose, always wanting to prove himself to be worthy. However, he also tends to keep to himself and acts very rude on occasion. This might be due to how he was sent to an orphanage at a young age and lacked socialization skills.

After succeeding Opal's position, he seems to have been mellowed out and no longer refuses to give out autographs.
