Research Hybrid Monster

Character

A nameless Mysterious Being locked away by Tsukuyomi for research, this so-called hybrid monster tore loose years ago and rampaged until Blast cut it down. Its final act was smashing into the cell of a ten-year-old Tatsumaki, moments before the S-Class hero arrived.

Appearance

Six eyes studded the face of this enormous beast, above a mouth crowded with pointed teeth and limbs tipped in claws. It moved on four legs in the manner of an animal, and a tangle of spiky black hair ran from its head down along its spine. Observers noted a resemblance to Overgrown Rover.

Personality

Whatever restraint it may once have had was gone by the time it broke free. The creature lashed out at anything nearby, savaging all who crossed its path as it tore through the facility.

History

Researchers believed the monster to be a crossbreed of two others, which earned it the hybrid label. After slipping its confinement it went on a violent tear, and its path eventually led to a holding cell where a ten-year-old Tatsumaki had been left abandoned. It battered the door open meaning to eat her, but Blast reached the room in time to kill it and spare the young esper. Its strength was never rated, though breaking out of a sealed cell and shattering a locked door marked it as no small threat, and Blast still dispatched it with apparent ease.
