Onua is the main character of the show and has a few screws loose. However, he is loyal to his friends and can create excellent puns.
Gali
She's lean. She's not green. She's a blue Toa machine! Gali is highly intelligent and has a knack for thwarting evil schemes.
Gahlok
Gahlok is just a regular guy.
Tahu
Tahu is a no-nonsense guy who wonders about Onua's mental stability. He finds Gali appealing, but wouldn't dare say it aloud for fear of Onua making a pun about bananas.
Pohatu
Pohatu is a Toa who wears the Great Mask of Open Sesame, allowing him to open any closed item by saying, "Open sesame". He is sometimes confused for YouTube celebrity EDICTARTS.
