Alien Mysteler (ミステラー星人 Misuterā Seijin?), also known as Alien Mystellar, were a pair of alien brothers, one good and one evil, that appeared in episode 49 of The Return of Ultraman. The two could be told apart by their torsos and size - the good was slightly smaller and had stripes, while the evil was larger and had "Dalek bumps." Subtitle: Galaxy Alien (銀河星人 Ginga Seijin?)
