Biography
When MakutaKlak was beaten by Blackout and thrown into a portal, he was captured by the robot army, who took him to Meca One, who asked MK how he got there. MK then explained what happened to him, told him all about Blackout, and offered him a "wager": if M1 released him, and helped him fight Blackout and his supposed ally, Uterio di Armechio, MK would show him to a dimension where he could win his war against the humans. He didn't accept, and instead had MK tortured. He then demanded that MK tell him where he was before he got to the EF universe, and how to get there. After MK answered that again, M1 demanded the exact coordinates of his previous location. MK guessed he was planning to invade, and laughed at him. M1 responded that he could get in "because it was written", and asked him if he was familiar with the initials "ZFT". MK said yes, and M1 then told him that the acronym had two meanings: the name of a book, and the name of an organization, and demanded the coordinates again. Finally, MK gave in and told him the coordinates. Having told him that, MK was no longer necessary, and M1 ordered his robots to dispose of him by putting him in an incinerator. MK said he'd come up with a way to get out, since he was a User. M1 told him that his title was meaningless.

MK then told him that somehow, he had informed the human army of Meca's location. M1 then left, and so did MK.

M1's base was then invaded by four human mechas, which were countered by the robots' Striking Venom.

Much later, Meca One was among the many people summoned by Blackout and Overlord Blackout to help the Rebel invasion of Mordor. He appeared driving a huge heavily armed vehicle and leading a robot army.
