Tyrannosaurus rex
The Tyrannosaurus is by far the strongest creature in game yet. With a bite attack that does 575 damage, it can kill all but the largest animals in a few hits. However, its power is curtailed by having an extremely small pool of stamina. This makes the Tyrannosaurus an ambush hunter. Unlike the Acrocanthosaurus, which is a persistence hunter, the Tyrannosaurus rex is forced to lie in wait, hidden among the foliage, until a prey item passes by. If its attack does not connect and do the necessary injury damage to cripple its prey's movement, it will be left in the dust.
Unique Ability: Upon release, the Tyrannosaurus rex will be the largest predator on the islands. However, due to its large size, Tyrannosaurus is also the slowest predator on the island. The element of surprise is paramount for success with this creature, as it's ability is still being determined and might not even have one, depending on its gameplay once added.
Other Facts: The Tyrannosaurus will have a feathered and scaly variant upon release.
