Red Rex

"These powered-up Rexes are... still not very strong. Try wielding one in each hand as dual weapons."

- Description of the Little Rexes in Sonic Unleashed (PS3/Xbox360)

The Red Rex (レッドレックス) is one of Dark Gaia's minions that appear in Sonic Unleashed. They are a powered-up version of the regular Little Rex. The Red Rexes are less numerous than their Little Rex relatives, but are much more aggressive. They only appear during the game's nighttime stages.

Overview
The Red Rexes and the rest of Dark Gaia's minions came into being when their origin source Dark Gaia fell apart due to its premature awakening in the beginning of Sonic Unleashed, with many of its fragments becoming Red Rexes afterwards. They first appear in Jungle Joyride Night Act I: Starry Night on the PS2/Wii version and Windmill Isle Night Act 1 on the PS3/Xbox360 version.

While faster and deals more damage than the Little Rexes, the Red Rexes are still some of the most weakest of Dark Gaia's minions as their attacks do little damage and they can be defeated relatively easily. However, they have much more health than the Little Rexes, which makes them surprisingly difficult to take out quickly. To compensate for their lack of power, the Rexes focuses on overwhelming the player with sheer numbers. The Red Rexes commonly appears alongside the Little Rexes, but they have also been known to appear in groups of their own.

The Little Rexes can easily be picked up by Sonic the Werehog on the PS3/Xbox360 version, making them ideal weapons melee weapons and throwing objects.

The Red Rexes and the rest of their kind were later refused with Dark Gaia to complete the beast. After transforming into Perfect Dark Gaia, the beast was sealed inside the planet's core following its defeat.

Physical Appearance
The Red Rexes are basically identical to the Little Rexes, meaning they look like a cross between a bulldog and a Tyrannosaurus rex, complete with stubby legs, tiny arms, and a rather large head with big jaws in comparison to their bodies. On their backs they have small spikes and emit purple smoke. They have neon red-colored skin with cyan body markings.

Powers and Abilities
The Red Rexes are able to move around by either teleporting into an area in a puff of purple smoke, or emerging from black puddles in the ground. As a Dark Gaia minion, the Red Rexes can possess people by latching onto the deepest, darkest part of the heart, and generate despair, negative emotions or even erratic behavior that are completely opposite to the person's personality.

As an empowered version of the Little Rexes, the Red Rexes are faster, stronger and more durable than their weaker counterparts. Despite their size, the Red Rexes are rather fast on their feet, capable of moving over several meters in a matter of a split second. They also have strong jaws, giving them a powerful bite, and though their bite has more strength than the Little Rexes, it hardly does any damage to opponents such as Sonic the Werehog.

Attack Patterns
The Red Rexes share the Little Rexes attack patterns, but they are far more aggressive and attack more frequently. When they first appear, they will shake their head from side-to-side, similar to looking for prey. When they see the player, they squeal, jump upwards and run towards the player. When chasing the player, the Little Rexes will pursue the player everywhere on the field, and will not stop until they catch up to the player or the player leaves the area. They usually attack their foes straight-on by flinging their jaws straight open at them in a swift motion.
