Kalmah was one of the antagonists in the BIONICLE series and was a tertiary antagonist in the 2007 storyline alongside Pridak and Takadox. He was also one of the Barraki, warlords whose goal was to overthrow the Great Spirit before he and the others as well as their armies were crushed by the alliance between the Order of Mata Nui, the Brotherhood of Makuta and the band of Toa.
He later along with the other Barraki were transformed into their monstrous forms following their release from the Pit when the Great Cataclysm struck Mata Nui who have became the Great Spirit.
Not much was known about Kalmah's past but he was one of the six warlords of the League of Six Kingdoms and ruled the northeastern region of the empire. Initially, Kalmah refuse to join the League as he doesn't want them to dictate his actions. However, he was then forced to join the empire when Takadox allied with Pridak
Kalmah was very cold and ruthless and excels at nothing
