Name - Sebastian Thorne 
Alias - Last Bastion of Virtue, Bastion
Age - 24
Power[s] - Tactile Telekinesis: Bastion's psychic aura serves as focus to his telekinetic abilities. Thus, he must touch an object in order to affect it. Tactile Telekinesis includes the following abilities:
(1) Lifting Capacity of ten tons and climbing, including the ability to lift fluids as if they were solid by touch
(2) Personal Force Field, extendable by touch allowing Bastion to ignore small arms fire
(3) Subsonic Flight
(4) Clinging (also known as Wall Crawling)

Weapons: Sebastian carries a buster sword straight out of anime. He uses it to expand his reach and cut through walls and vehicles. He would never consider using the edge of the blade against living beings and uses only the flat. The blade is also hollow and inside is a first aid kit.
Equipment: X-Badge Communicator
 
Weaknesses - Standard Human Weaknesses. His personal force field, while potent does not protect against non-concussive forms of energy (electricity, exotic radiation, sonic strikes...) that many other seemingly invulnerable people like Colossus or the Thing can shrug off. He also has a desire to prove himself as a hero that gets him into trouble.

How long at the Institute - Sebastian has been at the institute only about eight months and he has never been happier.

Favorite subject - The Xavier Institute does not have classes as in traditional schools. Each student had a custom crafted study platform and is assigned tutors. Currently his favourite field is Aeronautics which also includes time in the Blackbird simulator. He hasn't yet been authorized to fly the plane. 
Favorite teacher - Shadowcat. Sebastian has a tremendous crush upon Katherine Pryde
Appearance - Sebastian is a lanky tall male with chestnut hair with red highlights. When he first arrived at the mansion he had poor posture and had little in the way of self confidence. Thanks to training by Cyclops and Shadowcat in various martial skills he found his confidence has risen. His posture greatly has improved and as a result he is looking much more handsome.

The Last Bastion of Virtue has modeled his costume off of his favourite comic book superhero, Captain Marvel. He possesses a black uniform, a double breasted jacket with buttons rising up with the right shoulder. A half cape over his left shoulder, the clasp at his collar being a communicator in the shape of a traditional X-Symbol.

BRIEF Bio - Most mutants discover their abilities during puberty. The problem with Sebastian's was that, until he got into a horrible car accident, he had no idea he was a mutant. Stepping out into traffic to rescue a young girl, a semi-truck plowed into him before he could escape the street. Completely unharmed he was introduced to the Canadian way of dealing with mutants. Canada had no charter of rights, no amendments protecting free speech or laws against manipulating the press. CSIS, the Canadian Security Intelligence Service, dumped him in a small cell, imprisoned on trumped up murder charges for the unfortunate truck driver. They would let him out if he would submit to joining Beta Flight, otherwise it was Department X.

There being no laws against using torture in Canada, nor using information derived from torture, Sebastian's time in prison was abysmal. Weeks went by, he was scarcely lucid from malnutrition, dehydration and sensory deprivation before he was rescued. A young woman's head emerged from the ceiling, then the rest of her, floating down. In his wretched state he saw only an angel.

Since then, he has been training in Xavier's school to become worthy of that goddess 

Notes - Sebastian is a wanted criminal in Canada and eligible for extradition. He often has to make use of false identities.
