Magus- this was created by 'the-dreamer4' all the credit goes to him/her
A Magus is an extremely powerful wizard, they are actually Overlords. As such magi are immune to age, disease and poison. They also stop ageing after they reach their powers and after they gain their power they automatically de-age back to their prime (normally somewhere around the age of 25). A magi is so powerful that if they are hit with a spell, they spell will rebound at the caster twice as strong as it was before, this includes the killing curse. Actually a magi can only be killed by beheading or by magical exhaustion.
Also the earlier a magus comes into their powers the more powerful they are, for example if a magus gained his powers at the age of 20 he would be more powerful than a magus who gained his powers at the age of 30. However the most powerful magus so far, Darius Magus, came into his powers at the age of 25. The other magi come into their powers later on. Tsien Shi Magus came into his at the age of 37, Merlin came into his at the age of 31, Morgana le Fey came into hers at the age of 32 and finally the weakest magi of them all, Liam Magus came into his at the age of 50.
However it is ridiculous to call any magus weak, they can all perform wandless, wordless magic and can change their appearance (shapeshift). Also all magi have at least two animagus forms. Magi can also read minds and they have extreme physical strength, they can easily lift 800lbs without breaking a sweat. Magi also have perfect senses (vision, hearing etc.). Some magi can also activate all hidden abilities a person has just by being near them (an activator) and magi can also tell weather a person is good or evil (a soul reader). Also if a magus loses an arm or a leg it will grow back within 8 minutes. Magi can also control the elements (fire, water, earth and air, however the most powerful ones can also control lightning). Magi also have a perfect memory and can read a 1000 page book in 10 minutes and remember it word for word. All magi are also beast-speakers, this means that they can speak to all animals, both magical and non-magical. Magi are also telepathic and can project thoughts to people. They can also create a mind-speech link between people, this means that they can allow other people to be telepathic to others that they are connected to. However it is impossible for anyone to read a magi's mind, it they tried they would be probably killed from the backlash of energy. Magi can also 'see' and 'read' magic, meaning that they can tell who cast a specific spell when and where and what the spell did, this makes them a scanner. However one of the most useful powers a magus has is the ability to 'slide' around defensive wards, this means that anti-apparition wards have no effect on them (or any wards for that matter). Magi can also fly with out a broom and levitate. A magi's aura is purple and when a magus is mad or using their powers their eyes are florescent purple or have specks/flecks of purple in them.
However all of this power comes at a price, after a magi's 'awakening' or coming into their powers, they are unable to have children. However the only thing that could remotely challenge a magus would be an avatar, and that would have to be a very weak magus for even an avatar to have a chance. No, really the only thing that could challenge a magus would be another magus.
The currently recorded magi are:
Darius Magus
Merlin
Morgana le Fey
Tsien Shi Magus

This is a description of Darius Magus: Darius had shoulder-length wavy black hair and midnight-blue eyes. His face was more angular than Harry's was and he was a couple of inches taller, around 6 feet 3 inches. He wore a mostly black outfit: a simply designed black tunic with loose sleeves and loose black trousers. The tunic and trousers had a Celtic-like border embroidered in a florescent purple around the collar and cuffs, and a wide black belt with a silver buckle. The buckle had a round onyx set into it, surrounded by a circle of small amethysts.
