Character from Invincible by Robert Kirkman
An aging government operative who is completely invulnerable — you can't hurt him, but you can exhaust him, and he's getting too old for this.
Brit's power is total invulnerability — nothing can penetrate his skin. The catch is that he's otherwise human: no super-strength, no speed, no flight. He's an indestructible man with the stamina of a sixty-year-old. This makes him useful as an immovable object in combat but increasingly limited as the threats he faces get stronger. He's Cecil's reliable old guard — the agent who shows up when you need someone who absolutely cannot die.
Older man with grey hair and a weather-beaten face. Built like a retired boxer. Wears GDA tactical gear. Looks like someone's tough uncle, which he basically is.
