...you're serious?
Sorry but I'm not gonna sit here and pretend Ryu being without his shirt on showing off his ripped chest with a full beard isn't going to appeal to a certain demographic in a sexual nature.
I might as well just make this suggestion.
Men more often find sexuality in a lot of things that women just don't. I see men old and young, hot and not walking downtown shirtless in Toronto all the time. It isn't a thing, at all. Yes, hot men look good shirtless, but being shirtless isn't really the part that makes any of it sexy.
Having said that. There are people who have fetishes for balloons, but we don't usually say "well there are balloons in the background, which also appeal to certain demographics." Because we know, and you know, that isn't the intent.
When people are saying "power fantasy" what they're talking about is intent and assumptions about primary demographic. Male characters can sometimes come off as sexy, sure. But you have to be able to establish that there is an intent to make them sexually appealing to the point where a game runs up against it's release date trying to make sure they're coming across sexy enough
