Sham
From Bulbapedia, the community-driven Pokémon encyclopedia.
Charmaine (Japanese: シャム Siam), along with Karen, Will, Blue, Silver, and Keane, is one of the children kidnapped by the Mask of Ice and raised to be his servants. Charmaine was one of the sub-leaders of the new Team Rocket formed in Johto.
Her proper English name from Chuang Yi's Singaporean English Pokémon manga translations is Charmaine. However, Coronis who is known of coining fannames for manga characters who lack American names coined the name Shum based on her Japanese name. That caused many fans to call her Shum.
