Idk if this makes any sense but one thing I like a lot about w.bg is how Mike Walters (species) is simultaneously a force that affects and shapes so many others without really having a concrete 'identity' of his own. He's often the literal reason why 80% of the acting characters in the show are even involved at all. He's the reason Anne, Edgar, Chance and Shadow, Matt, Sly, and so many others got involved with the time travel shenanigans.
At the same time, despite the whole world seemingly revolving around him, he barely had control over himself. Every tiny action he takes shapes the fabric of the universe, but he himself literally cannot stay whole. He's so easily shaped by everyone wround him to the point that his identity is literally determined by his relationships.
Michael lost Edgar, but gained Mike, and hardened as a result (to protect him and the younger mikes) . Mike has Edgar, but he's constantly surrounded by the chaos of Michael, and he is the 'reasonable' one in their dynamic, the one in control, so he leans into it and basically becomes a control freak.
MDawg lives peacefully with Edgar, so he leans into it, too. MW is more complicated, but he's often sidelined and ignored, or told to follow others, so i think this is reflected in the way he seems eager to copy other people. I also don't think that the way he blends into the background is a coincidence. He's like a milder, more digestible version of Michael, which is literally his entire goal. He's trying to make himself more 'appealing' so that he won't be pushed away.
Lieutenant is obvious, he saw violence and had violence inflicted on him so he copied it. Stinky is the same situation but in the opposite direction. Tex is essentially the most extreme version of an outlaw, literally the general Michael archetype pushed as far as it can possibly go, with specific things emphasised (which makes sense as he's literally spending all his time around other cowboys).
I think the only one who doesn't really fall into one specific category is Mikey, but even he leans into the whole whiny, annoying kid at some points, because that's what his relationship to the older Mikes is like.
Anyway, in short, I've thought too much about something that nobody cares about (?), and the Mike Walters are a very impressionable species.
