Max was designed as an expert field surgeon, and despite some… issues, he truly is a wonder in the med-bay. To many the handsomest X-dog, and certainly the best-dressed, he possesses perhaps the sharpest overall mind.
It’s true Hugo is cleverer in a straight line, and Dexus more generally able across a vast array of fields, but neither is as socially adept or quick-witted as Maximus, who can ever be relied upon to immediately see the flaws in his brothers’ logic and deflate their egos with a swift correction, and possibly an insult. He enjoys verbally sparring with others, though usually picking someone’s arguments apart is like squashing a bug. Martially speaking he’s a good shot, but his physical cowardice holds him back from any real fighting.
