Umbrasaurus

Umbrasaurus (called Umbrasaurs in the UK and Canada) are hybrids of Renegade Shadows and Dinosaurs. They are strange creatures that lived in a sliver of prehistoric times.

Physical Appearance
Umbrasaurus did not have definite physical forms. They wandered around in a gauseous state, mimicing someone's shadow. They dominantly related to Renegade Shadows rather than dinosaurs. They could minorly shapeshift into the appearance of a random dinosaur species but couldn't hold the form for long.

Behavior
Umbrasaurus lived in deep forests in the prehistoric era. They would find a weaker dinosaur individual and become its "second shadow". When nighttime comes, they'd eat the dinosaur while they were sleeping. Being as hostile as they are, it is likely that, if brought into modern times via advanced technology, they would do the same thing to any living creature around them. Though mortal creatures, it is not known if they could devour a creature of a higher tier than them. They hiss and roar when exposed to daylight and will flee to the darkest place around. When under daylight, they become solid and attackable.

In nighttime, being a gas, they are not affected by poisonous substances, but can be burned, electrocuted, or frozen. Burning the gas of the Umbrasaurus instantly kills it.
