Infinity Mijinion (インフィニティー・ミジニオン) is a Maverick from the X era, appearing as one of the main bosses in Mega Man X6.

In the Games

Mega Man X6

Sprite from Mega Man X6.

Infinity Mijinion debuts in Mega Man X6 as one of the eight Mavericks on the Stage Select screen. He was built by Gate as a test pilot for manned weapons, possessing incredible data processing capacity. He proved arrogant and reckless when testing weaponry, causing a rift between himself and his staff, which eventually led to him being disposed of in a staged accident. However, he was later resurrected by Gate to serve as a Nightmare Investigator.[2]

Infinity Mijinion serves as the boss of the Weapon Center, observing the Nightmare-awoken Illumina. He floats around firing lasers, and splits into clones of himself when attacked. Defeating Infinity Mijinion grants Ray Arrow to X and Rekkoha to Zero. His weakness is the Guard Shell from Shield Sheldon, which sends him flying. A boss attack rematch with Infinity Mijinion later occurs in the ?????? stage.

Other Game Appearances

  • In the Archie Mega Man comic, Infinity Mijinion appears in the "Worlds Unite" arc as one of the Mavericks resurrected in Sigma's army.

Originally designed as a test pilot for giant-sized piloted war machines, the optic fiber material built into Mijinion's body gives him the processing power of several supercomputers. Within moments of climbing into a vehicle, he can scan and analyze its capabilities and be ready to pilot it into battle.

Behind the Scenes

Developer Commentary

"I guess it's because we had made it to the sixth title in the series, but we got into some pretty unusual themes for our boss characters, like scarabs and water fleas. From a designer's perspective, it seemed like a fun idea." - (Haruki Suetsugu)[1]


Language Name Origin
Japanese Infinity Mijinion (インフィニティー・ミジニオン) "Infinity" refers to his ability to split into seemingly infinite copies of himself. "Mijinion" is derived from the Japanese "mijinko" (みじんこ), meaning daphnia, a type of water flea.
