When one of MAT's officers crashed on Dangar's island while delivering a Monster Sonar, MAT came to rescue their friend, but had accidentally disturbed Dangar's sleep while he was in a cave. Awakened, Dangar proceeded to attack MAT and shrug off all their assaults. Hideki Go began attacking, but his craft ran out of fuel and crashed. As Dangar closed in on the crash, Goh was transformed into Ultraman Jack to battle Dangar instead. The two fought a lengthy battle until volcanic eruptions surrounded them. Jack finally managed to tear Dangar’s dreadlocks off and threw him to the ground before firing the Specium Ray into Dangar’s head, killing him.
