Relating to their resemblance to Godzilla Junior, the Jigoras' name is a simple anagram of Gojira.
The Toho Special Effects All Monster Encyclopedia give the Jigora a different name, instead listing them as Ancient Organisms of Torendiru (トレンディル星の古代生物. Torendiru-boshi no Kodai Seibutsu, lit. Ancient Organisms of Torendiru Star)
Visually, the kaiju closely resemble Godzilla Junior, having a similar skin tone and the same pattern of dorsal fins on their backs. However, they have small differences to their Earth-based counterparts - namely, the presence of two yellow stripes, one on either side of their dorsal fins.

In a flashback, Torema is shown regretfully shooting a rocket launcher at one of these creatures. Before she passes out due to her fight with Zagres a short while ago along with trying to help Godzilla against King Ghidorah, she gives Besuke Jinguji a video.
The monsters are shown to inhabit Torema's planet in the video Torema gave Besuke Jinguji. After Zagres and King Ghidorah attack the planet, then head for Earth, Torema vows to protect the threatened planet, as another one of the monsters comes to watch.
The Jigoras' roar is a reversed Showa Godzilla roar.
