I made Fedor using boxing and judo. I decided to go with boxing over kickboxing because Fedor just doesn't throw kicks. I wanted access to the overhand right and at probing range you can have a lunging overhand punch as opposed to a superman punch.
I was torn between Judo and BJJ but I decided that Fedor uses more trips and tends to engage enemies in the clinch when grappling as opposed to pulling guard. So I went with Judo in the end.
I gave him excellent clinch and ground grappling (offense and defense), excellent ground striking (more offense than defense, both are above average) average clinch striking, average standing striking, low kick offense and average kick defense. With the stats I focused more on cardio and strength than speed, but it's average across the board. (About 65-70 on each stat)
