In ULTRAMAN, after Ultraman left from his death by Zetton, the Science Patrol continued to fight various monsters and aliens until the so-named Star Cluster Alliance, an intergalactic alliance of various aliens from around the universe came to Earth. The alliance wanted humanity as part of their organization, even volunteering to get rid of all the kaiju on the planet. They (supposedly) got rid of all of Earth's monsters through various methods; however, it is possible that one monster went to deep into the Earth for them to capture/destroy properly.

Really the only "kaiju" who has appeared is Golden Fortress (basically King Joe) in the manga controlled by an Alien Pedan. It is speculated that near the end of the series, Zetton or a pretty strong monster may appear.
