Plumeria is a member of Team Skull, a villanious and criminal gang on which she serves the occupation of admin. She is known as the big sister of Team Skull because she treats her grunts in a strict, but caring way. She particularly dislikes disobedient or reckless Grunts, tending to think of them as "idiots", "numbskulls", or "dummies", but fighting for them whenever's necessary. She also has a reassuring relationship with Guzma (leader of Team Skull) caring for him and his success.
