Probably because he embodies that over-run, yet still popular archetype: Badass with a katana.

It doesn't help that Black Trailer left that question in the air and was never adressed ever again. It's not the same with Junior, Miltia and Melanie because their appearance had a full and simple cycle: Villains show up, fight happens, and Villains are defeated. Also, Adam has more impact in the splot than just a villain/antihero/antagonist/whatever he'll be, he's a character that is present in one of the main charatcers background(Blake) and is most likely yo be at the core of a subplot(White Fangs shenanigans).
