Episode 5: The Giant and Terrible-Monster vs. The Ultra Brothers
(featuring Great Ant Terrible-Monster Aribunta)
Seiji decides that Ultraman Ace needs to save the Duckbill crew but Minami doesn't think Ultraman Ace would know how to get himself underground so Seiji comes up with the crazy scheme of letting the monster go after Minami and this time he'd jump into the sand trap with her so they would transform under ground. The plan works but after ace uses his Metallium Ray on the monster he hears laughter. An alien Gironman, which has been controling the monster Aribunta, appears and catches Ace in a trap while the monster Aribunta appears on the surface, now spraying fire instead of spiting acid. Ultraman Ace sends a Ultra Sign into space, an SOS to the Ultra Brothers. The SOS is answered by Zoffy who flies to Earth and right into the ground to rescue Ultraman Ace. Zoffy gives Ace a braclet which reenergises him so he can fight Aribunta while Zoffy rescues the Duckbill and its crew.
Once on the surface Ultraman Ace finds himself being double teamed by Aribunta and Gironman, but Zoffy soon surfaces and after seeing Duckbill is safe, joins the battle. The two ultras kill Aribunta and Gironman by grabbing them and slamming their heads together, no need for energy weapons. Seij and watch the sunset. >Preview of next episode<. See you next week".
