The Gargantosaurus is the hybrid member of a race of alien shapeshifters that arrived on Earth, at the age of dinosaurs.
Biology
The Gargantosaurus is a cuadrupedal reptile of enormous dimensions, with red scaly skin, clawed feet, a long tail and a lipless mouth full of sharp teeth.
History
It is descended from a species of shapeshfiting-extraterrestrial creatures that arrived on Earth, during the Cretaceous.
Many members of the species take the form of dinosaurs and mammals, in order to camouflage with the animals. When dinosaurs got extinct, the aliens lose their shapeshifting abilities and got stuck in their changed forms, while some of his hybrid offspring retained the shapeshifting abilities.
A member of their race, got frozen in a giant ice block, until it was unfrozed and free from his ice prison in the modern era. This beast would called "Gargantosaurus" by humans, who he blended by taking the identity of "Gareth Bronmore".
