Monster Island S.O.S (怪獣島SOS Kaijū-jima S.O.S) is the 9th episode of Return of Ultraman.


Intending to spend time with Aki and her little brother Jiro on his birthday, Go is assigned to fly to New York to pick up a new weapon created by the MAT branch there, a Monster Sonar Scanner. MAT member Minami disobeys orders and secretly takes Go's place. Flying back from New York, Minami encounters a typhoon, causing his MAT Arrow to crash on an island where he's rescued by some scientific researchers. The team of scientists explain they've been there investigating possible monster activity and this new sonar device will prove useful. A search of the island reveals a hibernating rock creature living within a cave. Minami suddenly falls ill so Go, feeling responsible, must get a serum to him in time before he expires from any one of three possible fates - tetanus, an unstable island, or a giant, rampaging monster.
