From Bulbapedia, the community-driven Pokémon encyclopedia.
Sylvester (Japanese: サンシロー Sanshirō) is a character of the day in Reunion Battles In Nimbasa!. He participated in the Club Battle tournament but lost in a battle against Georgia and got knocked out in the very first round.
He reappeared in a flashback in A Unova League Evolution!.
Sylvester has at least two other Pokémon as those who entered the Club Battle were required to enter with three Pokémon.
- Sylvester's character design resembles that of Joltik's color scheme.
