If someone says they want to play an ape, I make up a 20-level ape progression. (Extra Attack is renamed to Going Bananas.) I'd just let the ranger take the other ranger subclass instead and just roleplay it as the ranger's companion. I'd do the same thing if someone wanted to play a wizard's familiar, too. Why not encourage out-of-the-box thinking?
So basically Winston from Overwatch. Just build it off a totem barbarian.
