AlenaGoji (also known as Antarctic Godzilla during the late-1950s) is a female Godzillasaurus kaiju and also the current owner of Alena Island, she is currently used by ShodaiMeesmothLarva.


The name "AlenaGoji" comes from Alena, and Goji, which comes from Godzilla's Japanese name, Gojira (ゴジラ).


AlenaGoji looks like a gigantic dinosaur-like creature with rough, bumpy, charcoal gray scales, a long powerful tail, and bone-white dorsal plates, shaped like maple leaves.


AlenaGoji is portrayed as a kind and benevolent creature, causing destruction only when acting as protector to Earth from a greater threat.

She is not aspiring to become the Queen of Kaiju like Godzilla (which currently holds the title King of Kaiju), but rather find her true love and build a family.


AlenaGoji is an ancient life form known as the Gojirans from the Permian period, having survived various extinction events by consuming geothermal radiation in a hibernation-like state at the bottom of the sea.


Permian-Cretaceous Period


The Permian-Triassic extinction event happened, AlenaGoji retreated to the ocean depths as the Earth's surface radiation levels declined, instead feeding on the planet's natural geothermal radiation. She remained dormant underwater for hundreds of millions of years until she was awakened by Meesmoth and CenturyBato's battle 12,000 years ago, surviving various extinction events such as the Cretaceous–Paleogene extinction event 66 million years ago.
