Mecha

Mecha are large humanoid machines used on the planet Adrax for multiple purposes, though primarily for combat. Mecha operate by establishing a direct connection to the operators brain using chakra.

Mecha come in three classes. The smallest is Android, which is only just able to fit a human operator inside. Almost anyone can operate an Android. The middle size which is from just over 7 feet tall to 50 feet is the Axis. Chakra development and special schooling is usually needed to operate an Axis. The largest is the Titan. Titans are anything over 50 feet tall and are rarely used. Very rarely is someone able to produce the chakra required to move a Titan, and any user able to operate a Titan would be better to have the maneuverability of the Axis.

Weaponry associated with Mecha are the meha wave, a destructive blast of chakra energy.
