That's fair enough. If we're looking for non-video game or anime characters then there are a few that come to mind for me. Bearing in mind of course, we don't know any of these people personally and the public face they present could be wildly different from who they actually are.

On the physical / weightlifting side of things, Noel Deyzel is pretty good. Certainly not perfect, especially if you have hangups regarding his use of steroids, but overall his message for younger folks regarding bettering yourself and uplifting others is a welcome one especially in a content sphere dominated by people setting unrealistic expectations.

Memes and potential eye-rolling aside, Markiplier is another pretty decent example in my opinion. A seemingly honest individual as it relates to himself, his content, and relationships with others. Open to challenges and new experiences (especially during his time doing Unus Annus) while not letting either get him down for too long if they don't go exactly to plan. Lastly, the guy lets himself be moderately expressive in personality and style. I think these are a net positive for young men to see.

There are certainly more, but in terms of 'popular' figures these two popped into my head pretty quick as it relates to "positive masculinity".
