KABOOOMMMMM!
Major Lawrence evaporated, dying a swift and violent death!
The powerful D Rank Gene Augur was one of the main reasons why the team of D Rank Lieutenants were able to survive against the Federation General for so long.
Unlike the other paper classes, alongside Major Mendez, he took the most risks, taking the C Rank Reality Sculptor head-on over and over again just so he wouldn't get a clear angle to attack his physically weaker comrades.
The overpowered regeneration ability of Gene Augurs and his endless reserves of ADE meant he could sustain such a reckless battle tactic.
But high ranking Gene Augurs are not truly unkillable.
The reason why they seem unkillable is because a combination of different abilities make their defense abnormally high, making it extremely hard for an enemy, even a high-ranking enemy to overwhelm their defenses and kill them in a single attack.
