Gomess, scientific name Gometius, is the very first Kaiju to appear in the Ultra Q TV series, which makes it also the very first Kaiju to appear in the Ultraman Series. As a result of this, as well as the interesting nature of the creation of his first suit (having been built by modifying a Godzilla suit), Gomess is one of the most popular monsters to have appeared in Ultra Q, and has gone on to become a recurring monster in the Ultraman Series.

Gomess was a Kaiju who, in ancient times, was the predator of the Kaiju Litra. In the present day, he was disturbed from his hibernation by a group of miners. He attacks the mining site where he was awakened. However, a Litra was hatching from her egg and engaged Gomess in battle. Gomess is killed by Litra's Citronella Acid attack. However, this cost Litra her life as well and both monsters died together.
