First spotted by Go who was patrolling in the mountains, he told his story to MAT, who were very skeptical about it. When the captain went searching the area though, Sadola appeared and attacked him. Go found him after Sadola disappeared, but Detton appeared from out of a mountainside to menace them. Sadola reappeared to fight Detton viciously, as Hideki Go transformed into Ultraman Jack. Facing two monsters simultaneously, Jack had a tough time fighting them both at first, but in the end, he destroyed Detton using the Spacium Beam and beheaded Sadola shortly afterwards using the Ultra Slash.
