* FriendToAllChildren: Has dressed up as anything from Colonel Sanders and Santa Claus for advertisements, to getting fully painted to look like [[ComicBook/TheIncredibleHulk the Hulk]] when going to visit an indoor playground, all to entertain Islandic kids.
* HugeGuyTinyGirl: Is inevitably this with any woman put next to him in his works, but it's especially apparent with his wife, who's 5'2. [[https://www.thisisinsider.com/the-mountains-height-difference-between-wife-2018-10 This gallery should give perspective]].
* TheOtherDarrin: He is the third actor to play Gregor Clegane after Conan Stevens (Season 1) and Ian Whyte (Season 2). Interestingly, he's actually the ''shortest'' of all three (Stevens and Whyte are both 7'1"), while still being a giant. This is helped by the fact that he's the most powerfully-built of the three by a significant margin, making him seem bigger.

* VocalDissonance: He tends to put on a deeper and darker voice when playing characters like Gregor Clegane, mostly because many find it hard to believe how light and welcoming his voice sounds in reality for someone of his size.
* WorldsStrongestMan: His most famous character, Gregor Clegane, is the strongest man in all Westeros. Hafþór himself won the RealLife WSM title in 2018, and finished in the top three of that competition six times before finally cashing in. He even became the first man to accomplish a legendary feat and then surpass it, as according to legend, Orm Storulfsson carried a ship's mast for three steps, broke his back, and was never the same; Thor carried a heavier mast for ''five'' steps, [[NoSell was completely fine]], and was utterly ecstatic when he finished.
** In May 2020 he set a new world record by being able to ''[[https://www.youtube.com/watch?v=2kEC7X1FUIg deadlift a weight of 501kg!]]''

* GentleGiant: Hafthor is extremely pleasant to fans, friends and fellow actors alike despite his utterly intimidating size and having one hell of a GameFace when he was still doing Strongman.
* HugeGuyTinyGirl: Is inevitably this with any woman put next to him, but it's especially apparent with his wife, who's 5'2. [[https://www.thisisinsider.com/the-mountains-height-difference-between-wife-2018-10 This gallery should give perspective]].

* StoutStrength: In his strongman days he consumed a lot of food and maintained a high body weight in order to maximize his strength, giving him a husky but still muscular appearance. After he retired from strongman and slimmed down for boxing his agility and endurance markedly improved, at the expense of some of the sheer strength he had before.

* WorldsStrongestMan: His most famous character, Gregor Clegane, is the strongest man in all Westeros.

* TheRival: To Eddie "The Beast" Hall, fellow winner of WSM. Wile it started out as a pleasant FriendlyRivalry between the two, it sadly turned more hostile in time over accusations of ego, cheating and attitude issues being thrown between both sides, eventually leading to them deciding to settle it in a boxing match scheduled in March 2022 (Hafþór knocked Eddie down twice and won by unanimous decision). This escalated even further upon his controversial world record deadlift of 501 kg.
* StoutStrength: As you can see in the picture, he sometimes has a bit of overhang to his belly, and his muscles are not sharply defined, but there is no doubt as to his strength.
