The Wraiths are an alien race, which are extremely legendary. They have been known to only exist as folklore, and only one person has actually seen one. The person has been dead for about a hundred years now.

Their skin is consisted of rock-hard, flexible skin. Their head has long 'blades' of this rock-material protruding across their head (pointy at the back). Their noses are slightly higher than a human being. Their eyes are beady, and always black with varying pupil colours as either light brown, yellow, red, blue, and green. Their mouth is mildly large, with sharp teeth. Their upper lips look like a beak extending down, but flat.

Their body is normally large. Their chest cavity is standard - that is, if you call muscled and wide standard. The average Wraith has a very muscular body, and large, muscular legs for bashing down doors with feet, and other uses, such as running if in light armour. They have talons on the front and heel of their feet.

The Wraiths are normally considered extremely strong. They always carry an assortment of weapons. They are always the elite of the elite in any situation.
(Relevant to the Turian in Mass Effect, but very muscular, and they have bold voices. Some people find their voices very smart-sounding and intelligent.)

Workout - The Wraith has exponentially worked out, increasing size by a few feet, and developing large muscular systems.
Mass Command - Due to the sheer legendary and epic appearences of the Wraiths, almost anyone will obey the Wraith, depending on the task.
Persuasion - With your epic status, you can EASILY convince others.
Dual Wield All - You are able to dual wield any weapon whatsoever. Rocket launchers, however, are more problematic. But it is possible.
Aggression - When in the heat of the battle, your brain will be absolutely determined to get the job done.
Rage - When close to death, or K.O., you enter a rage, increasing your size and muscular mass significantly.
Determination - You will not tolerate failure of any kind. You are more feared as a commander, and you can easily do the most dangerous of tasks with confidence.
Overlord Commander - You are very legendary. Everyone will notice you with high amounts of respect. Even braindead zombies would have the common sense to not fool around with you. You are also free to enter and leave the quarantine zone as you please, without any resistance from the quarantine guards. You also have developed a new technology of radioelectrons. You are gifted with a pistol that charges itself with an electromagnetic shell, from the oxygen, and fires a devastating shot to an enemy. It will go right through the enemy, but this gun is at very close range. It is antimatter, and therefore dissipates quickly. There is a huge amount of recoil and it takes a long time to cooldown after a shot. After a shot, the gun will instantly warm up incredulously.
