Characters who are defined by some sort of traumatic event from their past, often related to who they are now, and tied to how they got their powers (if they have any).
A general subversion of the "I have superpowers and it's amazing" theme found in most comics. Their powers are treated like a medical condition, instead of a gift, and realistically cope with such a bizarre situation.
The Mary Sue angle is obvious. What annoyed me the most is just how boring her character and character arc was. I saw more emotion in my childhood toaster from the 1970's than I saw in Daisy's performance. Any time she DID show emotion, it was completely out of place and out of nowhere.
Hell, even Ford gave more of a damn, and he was phoning it in big time with that one.
-Dion avoids working with Meta Humans. Not due to any sort of prejudice, but because any crime involving a Meta Human is handled by special forces, which is far too much heat to deal with. Not only that, but Metas and their powers are far more traceable and recognizable than any kind of evidence.
-Buys all of his suits and heist outfits with cash, from secondhand stores.
-His infamous "Patriot Mask" may look like a rubber mask, but underneath is a state of the art military ballistic mask. While not durable enough to take any round bigger than a 9MM, it's still a useful deception.
-Has spent so much time wearing latex gloves, that his hands feel strange without them on.
