The robot known as Meta-Form is a robot that Colette had to make for her father as an addition to the army. It was build only for combat purposes and was intended to only be used as such. Many soldiers in the army disagree with the addition of a robotic soldier, as some say it might trigger a very dangerous event.
Meta-Form is completely devoid of any emotion. It has no own will, but somehow manages to develop one when interacting with another robot Cura. When this happens, Colette sees it as a more dangerous being, as emotions are lethal. Meta-Form doesn't quite get emotions but finds them rather interesting.
Designed as a combat ready robot, Meta-Form has various weapons in its arsenal. It has guns stored in his armor, a flamethrower and can shift its arm into that of a sword. It of course has enhanced strength as well. Its core on its belly is its weak spot, exposed due to danger of overheating.
