Zhu the Emboar is a quiet, peaceful-natured Pokemon. You could consider him a hermit save for the fact that Tam the Plusle and Aya the Minun won't leave him be. He carries around a fireproof bag made from the scales of his late master, a shiny Charizard who lived in a volcanic region to the north of Tao Village.
Zhu has an admiration for fireworks and likes to craft them when he can. He caries around a big rake as a weapon for when fire is not appropriate.
His (and Tam and Aya's) home is in Snowy Village, a small area out in the mountains where Chill originates.
Tam and Aya love to cheer him on in whatever he's doing, using sparks as pom-poms when they're feeling really energetic. Despite him not asking for their attention and companionship, he does appreciate the sisters' company.
