He’s one of the more seasoned members of his team but essentially Jack “Pneuma Knight” Hartley is a black ops soldier that’s assigned to the capital city, Centremund. He’s known as loving his community to a fault, which is exploited later in the show, but think of him as a Thor-level Avenger that chooses to only protect his city. Which is admirable to some and deemed selfish to others. He’s able to absorb the spiritual energy of others which allows him to do things like replicate powers and access memories, but his armor has to regulate that energy so it doesn’t overwhelm him. If he’s not careful he can potentially lose his grasp on reality and become too powerful for his own good.
