Kon Kujira is one of the main protagonists of the show. He is Kin's younger twin brother and the drummer of Grojband. He is Twice as big and half as smart as his older twin. Kon provides some much needed muscle and despite his massive girth he has a surprising gentle giant disposition. Kon has a 'thing' for Trina and at times we get a glimpse that Kon is more intelligent than he appears and that his dim-witted person is merely an act. He is voiced by Tim Beresford.
Kon is a fat 13 year old kid with black hair and a red haed-band. He wears a white shirt with black sleeves and he has blue jeans. On his shirt is a black flame with a white letter B in it.
Kon is a dumb and stupid kid who loves having fun almost as much as he loves eating food. He is a big and lovable guy who has a heart almost as big as he is.

- Kin Kujira - Kin is Kon's best friend and brother.
- Laney Penn - Kon may possibly be afraid of Laney by how she treats him and his brother. Other then that, they are good friends.
- Trina Riffin - Trina thinks Kon is gross and want's the band he's in to get destroyed but Kon is in love with her. Despite his feelings for her, Kon is still okay with he and his band doing mean things to Trina and tends to hate her more than he loves her.
- Kin and Kon's names are "King Kong" without the "g's" at the end which is where the creator came up with their names.
