Two Giant Monsters Attack Tokyo
Operation Rainbow Monster!
Continuing from the previous episode, Ultraman briefly battles Gudon and Twin Tail before he is forced out of the fight after his color timer indicator expires. Thankfully, the two creatures -- one the natural predator of the other -- begin fighting one another, and end up taking their differences out to sea. The trapped civilians are rescued, but Aki is seriously injured. Goh, angering his teammates once more, decides to stay at her side till she's well again. Meanwhile Gudon and Twin Tail surface once more and Tokyo is ordered to be evacuated.
