The Sha'lythe Sect
He set things on fire if he thought it was necessary (which he always did), while shouting his catchphrase "FLAMMATION!".
He participated in the Battle of Mata Nui II by trying to set everything on fire. He was subsequently beaten up and sent back to whence he came.
At one point, he travelled to the year 150,084 (many years after his death) to fulfil a request by Quolas. He implanted a temporal displacement device on Tievie, just above the planet's core, which caused it to reverse back to how it was before the Borg invaded it.
He was eventually killed by Genetoes in a battle between the two.
