A monster that was created when Air Force Lieutenant Jamila Miller encountered a mysterious life form whilst aboard humanity’s first manned Jupiter research vessel.
The life form mutated Jamila and took over his consciousness, causing him to attack indiscriminately.

Jamila eventually returned to Earth out of a deep desire to reunite with his daughter, Karen.
He initially was able to remain himself and in human form, but when he saw government agents trying to kidnap Karen, he transformed into a monster right before Kenichi Kai and Julie Young.
In monster form, he trampled cars and then disappeared.

Later, the government took Karen hostage in a plan to weaponize Jamila.
Captain Essex used Karen to lure Jamila out, but he went on a monster rampage after being shot with a tranquilizer dart.
The captain and his agents tried to escape by car, but Jamila crushed them, car and all, before continuing his rampage.

Ultraman Powered arrived to fight, so Jamila used his powerful arms to pin the Ultra down.
Karen was able to convince Jamila to regain his sense of humanity and resist the monster’s instincts. In a final moment of strength, Jamila allowed Powered to end his misery with a Mega Spacium Beam.
