Spacer was 6th Kaiju by order of Appearance in the Fireman TV series, featured along with Gomerus in Ep.6, The Secret of Planet Gomerus.

Spacer was a Space Dinosaur Kaiju and sole resident held by Gomerus that appears half way in the episode and fought when Fireman came to the rescue of SAF, though the battle was kick, as Gomerus was the Greater threat.

Spacer had an oval like shape reddish brown color body; its head was located in the stomach rather than on top of the torso and adorn by two horns and long sharp fangs in its mouth; a toxic gas would be release from its mouth; Had tentacles for arms and tail which he would use as whips; it had dark legs with rough skin and hooks for toes. Its screech is akin to that of bats in the Gamera series.

Spacer made an appearance along other Ultraman Kaiju in the Ultraman Ace Manga – this would not be the sole instance of an indication of possible connection between the two properties sharing the same universe as we will see down the roster. Also, Spacer in other media seems to have 4 Tentacles rather than two as seeing in the Episode, however this was in the early concept designs.

In the Episode Spacer is seen roaming Gomerus early, but when SAF and Fireman arrived, Gomerus sends the Monster out to Stop them - in the end, Spacer is frozen with FireStop, then blown apart with FireFlash.
