Ultraman Mebius
This Monster reappeared in the series Ultraman Mebius (Urutoraman Mebiusu, 2006) as Zoa Muruchi.
Zoa Muruchi was created by the son of the original Alien Mates (from The Return of Ultraman,) but this time as a means of vengeance against the humans for killing his father. While Zoa Muruchi and Ultraman Mebius fought, Alien Mates met the principal of the boy his father adopted. After learning of a tragic story about his efforts to find the original Mates's UFO, Mates realized he had not only made a grave mistake, but he also sealed the fate of an innocent, undeserving monster. Overcome with grief, but wanted to believe in human kindness again. He then called out to Mebius to end it. Mebius used the Mebium beam, and destroyed Zoa Muruchi, after it let out one last anguish-filled cry, ending the suffering Alien Mates had gone through.
