He was originally a Mahi shepherd in Po-Koro. He is kind and cheerful, but down-to-earth. Since he's a Po-Matoran, he also is the physically strongest member of his team. He was chosen by Turaga Seihu when he fought Draku's minions as they invaded Po-Koro. He uses a pair of side-handled clubs called the Rock Tonfas.
His fighting style is described as forceful and impactful. He uses hard punches, kicks, smashes and takedowns (Similar to Muay Thai kickboxing and wrestling).

Looks kinda cute;) nice idea to make him muay thai boxer!
Thanks. I thought it would fit too considering that in the actual Bionicle storyline, the Po-Matoran were among the physically strongest and most athletic, and Muay Thai was a fighting style with hard hitting techniques.
