Quick Notes - Heavy
Heavy's name is Mihail (generally romanized Mikhail), commonly shortened to Misha. He is the tallest mercenary, has a strong, fat torso and arms, and comparatively thin legs.
In-game, he has a bald head and tanned pink-orange-toned skin, slightly darker and duller than Scout's. He uses the same blue eye model as most of the mercenaries. He has a wide, square, prominent jaw, and very little shaved hair around the ears, with a heavy browline, and a large, hooked nose.
In the comics, he is drawn with lighter skintone reminiscent of Scout's model (though slightly more orange/yellow toned).

Notes on Writing Heavy by Rayclubs
This is technically just every post the blog owner has tagged "tf2 heavy", but quite a lot of those posts are pretty useful in terms of either linguistics or just general characterisation. I /could/ go through and only link posts that don't include headcanons or memeing or whatever but where's the fun in that. Also I'm lazy.
He also has a linguistics tag. Which technically covers every mercenary, but a lot of it is Heavy bc they are a Russian speaker.
