Litra, scientific name Littlalia or Litolaria, is a giant bird monster who resembles the phoenix of legend. Litra first appeared in the TV series, Ultra Q, and alongside Gomess - Litra's natural enemy - is one of the first monsters to appear in the Ultraman Series as a whole.

This prehistoric bird is the ancient enemy of Gomess according to myth. After coming across a stone egg deep in the Earth, a set of miners decide to dig down even deeper, and awake the underground monster of legend, Gomess, by mistake. The Kaiju follows them to the surface, and starts to rampage.

Soon, a young boy made the stone egg hatch into Litra; the ancient bird-like creature was supposed to stop the kaiju's rampage. Litra emerged from the egg and set forth to Gomess. As the bird-like Kaiju approached, Gomess bellowed, and the fight was on. The two battled to a standstill until Litra released Citronela acid, quickly eating through Gomess' body and killing him, the dinosaur-like beast collapsed, and so did Litra, the deity's destiny was done. Litra would later be put to rest on its own funeral, built by the survivors of Gomess' attack.
