Gelsi is a member of the Gorilla Tribe.
Gelsi only appears in the game Legends of Chima Online. She is the only female Gorilla besides G'loona, which also makes the Gorilla Tribe one of only three tribes to have two known female characters. Nothing is really known about Gelsi or her personality. She seems to have been friends with Elida, since she asks her how she's been. She comes to Elida seeking help with "bummer plants", wanting them to be destroyed.
Gelsi has a band around her head and flowery clothing like G'loona. Her voice is somewhat low for a girl.
