Taught never to rely on any one thing, he keeps a number of tools on hand at all times.

Grenades: Never keeping more than two on him at any time in uniform after hearing the story of his grandfather pulling the pins of a dozen soldiers at once. Chaff-nonmagnetic metal flakes meant to scramble electronic measures, Knocker-compressed microfine Metal powder used to blow open door with high kinetic output or stun multiple organic opponents
[url=http://youtu.be/vVngZM_MU4M]throwing irons[/url] As designed, but his are hollow and fluted with multiple tiny holes to ensure a sucking wound to let an opponent bleed out if organic or hydraulic if he can land the right shot. Kept on his person on a thigh holster even out of uniform.
Sling: Simple kevlar thong used to hurl a simple fiberglass sphere with enough force to break bone, When he slips a thread through the ring of a grenade, it becomes a twofold weapon to launch the five pound weapon to impact before exploding. This he also keeps on a pocket with a hard rubber ball in civilian attire.
[url=http://www.blackarmor.com/index.php?category=casual-jackets-body-armor&p=47]Uniform[/url]: A class A-III fabric armor in the make of a body suit with impact plastics Velcro atop. Can withstand up to .357 at point blank with only broken bones. He also has the same material available as a denim jacket and blue jeans for undercover/civilian wear

[b]Powers:[/b] 
Physical mutation: His physiology is unique in several different ways. His bone structure allows him great flexibility. His spine is more flexible than an ordinary human, enabling him to remain in a crouched position for a long time and perform contortionist-type feats without causing any damage to his spine. Bamf's balance and bodily coordination are all enhanced to superhuman levels. He also possesses superhuman dexterity, being able to manipulate items and fence with either hand and his tail. He lacks his fathers prehensile feet but does have five fingers and toes that let him pass for human easier. He has a prehensile tail, allowing him to grab onto objects with relative ease. His tail is strong enough to not only support his body weight, but also lift an adult man completely off the ground at the same time, and is deft enough to fight with while holding a sword or blunt object. His eyes (which are constantly washed in black) grant him a marked degree of heightened night vision.

Wall crawling: Where his father could blend into the shadows by warping light, he can stick to shadows by an instinctive connection to the home dimension of his father and grandfather. This allows him to fight in a third dimension most others lack but also means he can not cling to an activated ceiling light for example beyond his physical strength.
SKILLS
Trained in the formal art of Ninjutsu by psylocke, he puts his mutant physiology to best use as an infiltrator. He has been taught how to consciously filter out the lightest levels of psychic invasion. 

Magic(k): While a weak skill now, it is to note he keeps a store of occult books and the like, some real, some just to piss his dad off. His superhuman dexterity makes the sleight of hand as easy as breathing but he does also practice a few practical incantations like sewing glyphs into all of his clothes so they will put themselves away.
[b]Personality:[/b]
For the most part he is happy go lucky to hide his pain of loosing all the life he had ever known. He has always had a fascination with sleight of hand and stage magic, On quiet nights he loves to curl up with horrible kung-fu movies and a plate of sushi to pass the time away whenever a girl isn't available. Even being the prodigal son of two great mutants and the grandson of even greater mutants he is still a physical mutant, he can never pass in normal society. As such he has a deep seeded hate for 'pretty' mutants who can pass by unseen and will bend over backwards, literally, for those who cant hide themselves. Where his father was a devout Catholic, Magnus has always carried a despise for the church's position on mutants to the point he is a vocal follower of Loki, a 'real god' of Asgard that has put many a hero of earth on their heels.
[b]History:[/b]
In another time and another place the mutants lost at Alcatraz. It became a campaign of slaughter on a planet wide level, In that reality, Kurt wagner and wanda maximoff had a child who was born in bloodshed and forced to fight from the time of a child, in time it became evident that they wouldn't survive so they went to the oldest and most powerful enemy they knew, Apocalypse. They agreed to become his newest horsemen if he got their son to safety, The first mutant agreed and sent the teenager to a reality whose other Aubin-sur matched his own temperament and psychic harmonics. The new Apocalypse understood what had been done with a simple letter tattooed int the boys chest, and handed the boy over to Xaviers school anonymously. This Xavier knew the boys past and did all he could to try and help heal a lifetime of war, but healing can't be done if it is unwanted. For years he studied at the academy and learned his lessons to master his powers so they didn't master him but there was too much ill will in his heart to be a member of the x-men so he jumed at the chance to become an avenger.

Note: Magnus has a fear of heights/falling from a failed attempt to teleport that broke his spine, resulting in two of his bones to have to be fused to let him walk again.
