One of The Six Stats, abbreviated as STR.
This is the stat that determines how strong a character is. This is usually broken down into two levels: how much a character can lift/carry/push/pull, and how damaging a blow from this character is. Of all the stats, this is the most historically blown-way-outta-proportion of all of the stats, and is usually the choice stat of an action or martial arts hero, and especially comic book characters - Strength is one of the defining characteristics of the Flying Brick.
Here's a guide for Examples:
12-15: The character is reasonably in-shape to athletic. The high-end stat-wielders are your typical good high-school athlete.
16-19: Professional athletes, fighters, etc. Expect most Olympian athletes to be pushing 18 or 19
20-23: These are the beginning of your super-heroes. Expect car-lifters to be common in this group, if not guys that make their own doors... through brick walls. Also expect a fight against a typical muggle to end with one punch - in that their skull will probably be a fine mist.
24+: So you've upgraded from lifting cars to juggling Abrams tanks, eh? These are some of the morepowerful superheroes, a LOT of mythical figures, and typically anyone who can wrestle a dragon.
30+: Dragons themselves, obviously. Plus superheroes whose main power is strength.
40+: As the strength scale is pretty easy to expand with bigger and bigger lifting capacities, it should be no surprise that some superheroes or monsters get a 40 or much higher.
50+: cosmic-scale or Eldritch Abomination monsters tend to have 50 to immeasureble strength scores.
- Batman, being a badass normal, pushes the upper-levels of this tier, shying just short of being able to regularly lift a car. This means he's still able to lift more and fight harder than Olympic-level weightlifters and grand-master martial-artists. Not surprising, though, since he is the poster-child for Badass Normal.
- The typical level of power for fighters in Baki the Grappler. As the comic goes on, it becomes more and more common for the fighters to kill mooks or bystanders with little effort, and sometimes even each other. At one point, Baki is thrown - not in one go, mind you, but through successive hits - through a series of concrete walls.
- Guts of Berserk has this simply by dint of being able to swing around a huge frigging slab of iron with one hand as if it were a more normal sword.
- Young dragons have strength up to 30.
- Lesser giants still have way superhuman strength in D&D: Hill giants have 25, Stone giants get 27, and Frost giants have 29
- In The Order of the Stick, protagonist Roy Greenhilt has 29 strength. Evil Counterpart Thog has at least a 22.
- Any Mario character with Super Strength will generally be able to plow through six-foot walls and crush meteors with little effort. That applies to Mario, Luigi, Wario, and Bowser.
- Adult dragons have strength between 30 and 40.
- The Balrog from Lord Of The Rings has strength 35.
- Greater giants fall in this area: Fire giants have 31 strength, Cloud giants have 35, and Storm giants cap out at 39.
- The Goku of Dragon Ball can break the freakin' SUN with a single punch.
- Saitama of One-Punch Man. It's right there in the title: he kills everything with a single punch.
- Superman. Earth-2 Superman especially. He killed the Anti-Monitor with one punch for crissake!
- Captain Marvel. He has, on at least 2 occasions, gone toe-to-toe with Superman, with the Big Blue Boyscout pulling absolutely no punches. He is the only non-New-God, non-Kryptonian, non-Daxamite, other than Doomsday, to do this, by the way.
- The Incredible Hulk is probably the ultimate example of a strength-based superhero. He's stronger than nearly any other character you could name when he's calm, and when he gets angry his strength increases. Theoretically without any upper limits: some of his canonical feats of strength when sufficiently pissed off have included lifting an entire mountain and shattering tectonic plates just by walking.
- Of the Six Stats, Strength is possibly the most common subject of Chuck Norris Facts - his roundhouse kick would key off of this stat.
- Elder dragons have strength up to 45.
- The Tarrasque has strength 45.
- In The Order of the Stick, the Monster In The Darkness appears to be at this level, as his softest/lightest attack sends a human character flying through a brick wall, landing hundreds of meters away.
