Maxilos

Maxilos robots are large robotic guards that served the Order of Mata Nui prior to the destruction of the Matoran Universe.

Biography
Each Maxilos is made from a combination of protosteel and stands at around twelve feet tall. They are intensely loyal to recognized Order members, and will follow through their orders without question unless they are given an order that violates their programming. Due to their inability to think for themselves beyond following simple commands, they are not considered sentient.

The energy source that the Maxilos run on is some kind of "black fire", which they can also channel through their swords and use to attack enemies. In addition to these swords, they are equipped with shoulder-mounted Cordak Blasters. Their armor is airtight and protects their internal systems from water and gases. They are also extremely strong.

History
The Maxilos were created by Artakha on his island and given to the Order of Mata Nui. The Order decided to use the Maxilos to guard The Pit and their headquarters on Daxia.

During the Battle of Zev's HQ, Kakamu threw a Makuta named Jerok down to the battlefield, where his armor was crushed by a Gnoll captain. Jerok wandered the Matoran Universe in antidermis form, looking for a new body to occupy. He eventually came across a Maxilos robot and inhabited it. He decided to track down Kakamu to get revenge, but when he found him, Kakamu destroyed the Maxilos with a Jetrax T6. Jerok's antidermis escaped from the destroyed Maxilos but evaporated before he could find a new body.

The Maxilos were presumably destroyed along with the rest of the Matoran Universe.
