The Gaston act was brilliant, esp. with their surprisingly similar appearances/builds, along with the similarity personalities/personas.
Plus, I'll go out on a limb and guess I'm not the only person (esp. not the only gay male) ever who found myself a little bit attracted to Gaston when i first saw "Beauty and the Beast". Which was even more awkward & confusing than most childhood crushes on cartoon characters (already plenty awkward/confusing,haha). O/c i think MMK had hypothesized--correctly-- that a significant segment of his own audience must share this secret & embarrassing formative experience. I strongly suspect that he was consciously trying to evoke it, to trigger or heighten various psychological effects in viewers who resonated with the awkward dé ja vù.
Which gets to a point made already by several ppl: one quality (of many) that enthrones Muscle Master Kevin in the very highest tier of this genre (which he pioneered to a great extent**) way way above many later batches of "muscle masters"/findoms, etc. Is that the man is seriously intelligent. You kinda see it in his porny videos themselves; he is far more articulate & eloquent in his speech than most pornstars.
But yes, I've also glimpsed posts put out by other, more cotidian personae of his, in other venues, and his apparent level of education, cultural literacy, self-awareness, & even fashion sense are in line with what you'd see among young professionals generally working in the creative/entertainment fields. He also still (i think?) is involved with whatever kind of "indie" pro-wrestling, which of course overlaps with the pornier muscle + domination stuff. He seems to be involved in various milieux and projects, which overlap here and there, but also diverge wildly. But he doesn't act like any particular one (even the gay porn one) is like some dark, shameful secret identity that he's terrified that people will find out, and then all his ventures are doomed or something ridiculous like that. The fact that he can pursue such diverse endeavors, but reconcile them into one coherent and successful life, just demonstrates further what an intelligent man he is. He has obviously the confidence you'd expect of such an extremely alpha male, but has also gone about his work and the associated empire-building so that he is operating independently of any external authorities to appease. His character/attitude/persona exempt him from worrying or really giving a damn if his output as a whole "makes sense" or is "socially acceptable" to anybody other than him and his many fans, supporters, worshippers. And it seems that he has also done it all without ending up dependent or subordinate or vulnerable to anybody else who could potentially use whatever leverage to coerce him into giving that damn.
