An unknown life form that came to Earth from a space between zero-gravity fields.

A blue and a red meteorite that were found in the Balone Desert merged and became giant. Antenna-like four-dimensional fibers emerge from the holes on the protrusions, and it attacks using the fibers to take people to a fourth dimension.
When there were two separate meteorites, they were taken to the SSSP base.
There, they merged and took the entire base to a fourth dimension, trapping and disillusioning the members within. It fought the Defense Force by sending its tanks flying and putting its fighter jets on the ground, overwhelming them with mysterious phenomena.
When Ultraman showed up, it used its antennae to attack him, but it was eventually defeated by a series of Spacium Beams.
