Bitil

Bitil, like all Makuta, once worked solely on creating new Rahi. More recently, he and several other Makuta have been assigned to invade the Swamp of Secrets in order to control Mata Nui's situation and prevent the creation of any more Toa of Light by turning Av-Matoran into Shadow Matoran.

Bitil and Gorast where the first to side with Teridax when he took over the Brotherhood of Makuta. Bitil was also the first Makuta to notice the changes that came with their evolution into pure energy.

Abilities and traits
Most of the 42 Kraata/Rahkshi powers. Like Krika and Gorast, an unknown force took away his access to some of the 42 Kraata powers, including his shapeshifting abilities. This means he is currently trapped in his insectoid form, perhaps permanently.

Mask and weapons
He has an unknown Kanohi, and two twin Vahki-like staffs. He also has wings, though bulkier than Gorast's, and a Nynrah Ghostblaster with green ammo.

Trivia

 * The most remarkable, easy to spot feature in Bitil is his scarab shaped head.
 * His name is based on beetle, because of the shape of his Kanohi.
