examples: prototype, megaton rainfall, asura's wrath, metal gear rising: revengeance, bayonetta and maybe kinda saints row 4.

p.s. I prefer games that are available on GOG, but will go for other stores if GOG doesn't have them.
p.s.2. Is there any hope GOG will ever sell [PROTOTYPE] ?

EDIT: I am not talking about games that feel like the Arnold Schwarzenegger movie commando (where he runs around gunning down a small army by himself).
What I was talking about was more like ridiculously powerful super being.

[PROTOTYPE]: player character glides around turning his arms into giant mace, smashing tanks with them and shrugs off getting shot hundreds of times.

Megaton Rainfall: megaton rainfall player character is a semi transparent purple guy that flies around like superman shooting purple fireballs out of his hands.

Asura's Wrath: player character is a super strong angry guy fighting monsters the size of mountains with his bare hands.

Metal Gear Rising Revengeance: player character is a cyborg ninja/samurai that can slice robot dinosaurs in half with one swing of his sword.

EDIT2: player character needs to be shown to do at least one of the next things; strong enough to at least throw cars for a distance of at least 10 meters, run faster than 50 kilometer per hour, jump higher than at least 4 times its height or fly without needing a plane, helicopter or jetpack, create blasts strong enough to at least blow up a car, tough enough to shrug off at least small arms fire.

Just Cause 2 & 3

id games are well known for popularizing the release of their developer codes (e.g. clipping off, instant ammo/health, and GOD-mode, to name just a few of the most popular ones), which were originally meant to be just used in pre-release as testing aides.

'not sure if that's what you're looking for, though.

Darksiders ? (I'm just beginning the game, but you play War, one of the 4 Horsemen of Apocalypse.

Ain't that the whole point of Doom (2016) and Doom Eternal?

"There is only one dominant life form in this universe and it carries a steel-barreled sword of vengeance."

First Prototype was DRM free on Amazon forever ago. Not sure if it still is, or if they still even sell downloads.

I'm not really sure what you're asking for to be honest, but off the top of my head I'll say the newer Wolfenstein games. They are very centered on the idea that BJ is an unstoppable Nazi killing machine who cannot die, even when decapitated.

Alien Shooter
DOOM
DOOM II
Painkiller Black Edition
Serious Sam: The First Encounter
Serious Sam: The Second Encounter
Zombie Shooter

Star wars the force unleashed 1 and 2

Second this.

The far cry games (except 2) gives the feel of being powerful, but nothing like Jedi strong.

I didn't play Metal Wolf Chaos XD but I think it is something you are looking for.

Wizard Mode in any Roguelike. Demigod mode in DF, creative mode in MC, and probably other things like that.

Any SNK fighting game, such as King of Fighters. Several of them are on GOG.

Based on the games you listed, you would probably love the Devil May Cry series. DMC3 and DMC5 are much better than Bayonetta in my opinion.

Mercenaries games, though the only one on PC is a dubious port of a somewhat janky game, and is not on GOG. But play them on console if you can.

Basically every action game?
