Why do so many of these 'muscle men in drag' characters keep showing up in isekais? It was intersting and a little funny a few times, but its gotten old. Besides, Bisky did it best
I have the theory its something like the (I googled the term, because its called different in my language, so I dunno if its correct) black token guy. Pretty popular especially in the 90s with movies like Scary Movie, where they joked about this. Its basically playing pretend, that you care about diversity. And I guess it happens here too. The first appearance of such a char was in One Piece as far as I remember. Mr 2 as a skinny version and later on Ivankov (yea had to google that too, because I tried to forget^^)
I guess some people in Japan just find it funny, so why its implemented and in most cases its minor chars anyway, that rarely appear again.
