John Stone is Battlestone, a Nu-Gene and founding member of Brigade.
Discovering as a kid to be Nu-Gene positive like his father John followed him to New Heaven, a refuge for Nu-Genes built to keep them safe from hateful humans.
Years later his father's enemies killed his mother in revenge and young John, considering his father responsible for such tragedy, began to harbor a great deal of hate for him.
During the forties he was invited in the Allies by Roman.
Some time later he was assassinated and brought back to life through Project: Born Again.
To make things worse John furtherly strained his relationship with his brother by bringing him back to life through Project: Born Again against his will.
After being expelled from Youngblood following the accidental death of one of his subordinates during the Persian Gulf War John started to work as a mercenary until he founded the first version of Brigade with Lethal, Kayo and Boone.
Superhuman Strength: John possesses great physical strength, his punches can throw an opponent a dozen of meters in the air and during one of his first missions with Brigade he was seen lifting 500 kg of marble with one hand and using it as a weapon in close combat. He was able to keep up in a battle against Roman.
Superhuman Stamina: Thanks to Project: Born Again Battlestone can keep fighting even after sustaining incredible damage, like being repeatedly shot, stabbed or even having a limb ripped off.
Superhuman Durability: In addition to being resistant to damage Battlestone also possesses an incredibly high pain threshold given to him by Project: Born Again. Some of his greatest displays of durability have been surviving close range explosions and building collapsing on him, although he was gravely injured both times.
