These dudes are not that hard if you put some levels in melee at the very start of your game. I recommend at least 145 or something higher

You can knock them out even the high level ones using just your fist

If you have atleast 180 in melee then you won't have problems facing 200+ leveled dilo (still using fist)

I tamed one that way

His name is dwayne and he is very green
