When this character shows up in RPGs, it will often overlap with The Big Guy trope, but as far as fighters go, this character will usually be the odd looking guy with increased strength/agility and animal-based or generally very melee-based attacks, probably The Berserker.
As this trope is rather redundant to Nature Hero, one is looking to merge this into it.
- The classic fighting game version is Blanka from Street Fighter II, almost more animal than man.
- Tam Tam from Samurai Shodown; note that he comes complete with Cute Monster Girl kid sister Cham Cham, who's playable in the second game. As well as being one of the few Catgirls who actually has some feline behaviour.
- Ayla of Chrono Trigger is a Wild Woman from the prehistoric past. Leah from Chrono Cross is much the same, and has a few of Ayla's special attacks too.
- Tends to show up in Professional Wrestling, too. Typically this one's big, bulky, and not the most technical guy out there.
- Gau in Final Fantasy VI
- King Rasta Mon in Saturday Night Slam Masters.
- The eponymous hero of Tomba!!
- El Cabaillo Blanco, the reclusive Real Life ultrarunner from Born to Run who is rumored to be a former boxer who killed his opponent in a bout.
- Yamawaro from Onmyōji who provides the page image.
- Akihiko Sanada in Persona 4: Arena is built off of this archetype. He was originally going to be a Man in Black-type character inspired by Jason Statham in The Transporter, but developers wanted a Wild Man so he was tweaked.
- A non-video game (but most likely inspired) example is Burk from A Path to Greater Good and its reboot Hero Oh Hero (the latter of which also gives him a better dressed Aristocrat as a foil). He wears nothing but trousers (or Goofy Print Underwear after he lost them) and a shaggy head of hair while fighting with Good Old Fisticuffs.
