My personal headcanon version of the Engineer who leads...or tries to lead...the Chaos Insurgency. This particular Engineer has actually tried to return the CI to its original principles and has gotten some to follow him. He's done away with the gratuitous brutality in his group and gotten them to fight in a more honorable manner...
...but there are other, major elements also calling themselves the true Chaos Insurgency that do not answer to him and would rather see him dead and one of them in his place...
(I am genuinely shocked how close SDXL got to what I see in my head for what my Engineer looks like. I don't know why but Bing was not as close with him.)
