History
Ungramon wanted to invade the Earth for nutrient reasons. He used the chouju Gitagitanga to destroy industrial areas. TAC was quick to respond to the situation and Alien Ungramon explained himself that he wants to use nutrients for his own species. The next day, Alien Ungramon summoned Gitagitanga to destroy more industrial areas. He trapped the sixth Ultra brother and proceeded to join the chouju. He grew to enormous size are downed TAC's planes. Hokuto summoned Ultraman Ace and Ace fought against the duo. The two chouju overpowered Ace and the sixth Ultra brother called the Ultra star to encourage Ultraman Ace. Ace destroyed Gitagitanga with the Ace Lifter. Enraged, Alien Ungramon fired his lazer but Ace set him on fire with an Ultra beam. Groaning, Ungramon collapsed then exploded.
