Harlan Alvarez

Harlan Alvarez is an Awakened Sage and Master Sergeant of Sentry. Being the lone survivor of a previous generation of awakened children kidnapped and bred for combat by the Alvarez Orphanage, his decisive results and clear potential led to him being scouted for recruitment into Sentry's S-Zero, with him eventually taking up a role among the Four Horseman of Sentry under the moniker of Pain.

History
Harlan was taken by the Alvarez Orphanage at a young age, forced to kill his parents as part of the induction ritual and immediately thrown into a life of ceaseless training and combat. The inescapable pain of a life built off of beating and killing other children his age for the sake of his own life caused Harlan to slowly detach himself completely from his emotions, turning himself into an unfeeling weapon of mass destruction to cope with the path he was being forced down to survive. This change within him resulted in a much more efficient and destructive combatant, with Harlan being the stand-out fighter among his group and slaughtering any remaining members with no qualms whatsoever upon being asked to by his captors, as is tradition. Having demonstrated fantastic control over his abilities, an immense degree of potential, and a seemingly unshakeable willingness to follow whatever orders were given, Harlan was quickly recruited into Sentry, with his skills and abilities being refined through further training and experience, eventually being granted the title of Pain as a member of the Four Horseman of Sentry.

Abilities

 * Monster-level Physicals, Almighty-level Endurance
 * Aura Manipulation

Osteokinesis
Harlan is able to utilize his Aura to manipulate his body's osteoclast and osteoblast cells, which grants him absolute control over his body's skeletal structure and calcium production and concentration. He uses this to generate bones as his primary means of attack, being able to manipulate them to various shapes and sizes for a wide array of techniques. In addition to offense, his defensive abilities are also heavily strengthened by this ability, with him not only being able to apply his bones as types of shields for protection, but his very skeleton having extra concentrated multi-layers of bones that make his body much more durable than he appears. His ability to instantaneously create new bones also gives him a form of regeneration, rendering any kind of break or fracture moot and making it nigh-impossible for him to suffer an internal injury.
