- Thresh was designed by CertainlyT.
- To "thresh" means to separate grain from wheat, usually with a sickle, or by a revolving mechanism. Thresh's weapon is very similar to a sickle, and his victims and their souls could be seen as the wheat and grain. The way Thresh swings his chain could allude to the way grain is separated from wheat using a revolving mechanism.
- Thresh is the first champion to be released in 2013.
- Incidentally, his base health at level 18 is 2013.
- Thresh was the first champion to be released with the new champion price structure, costing 7800 for the first week.
- When Thresh dies his own soul is harvested by his lantern. You can faintly hear his fearful laments as his soul is removed.
- Thresh's story is similar to that of the main antagonist, a mad doctor, from the movie Asylum. Both loved torturing their prisoners/patients until the victims' riot which resulted in their revenge against the warden/doctor, but both returned to continue their murderous and sadistic acts.
- Thresh tricked Lucian's wife, Senna, and trapped her soul in his lantern, for which he seeks revenge.
- The weapon that Thresh uses is similar to the - a weapon that consists of a sickle attached to a metal chain with a heavy weight at the end. The weapon was traditionally used by ninjas in .
- Thresh and Urgot were previously the only ranged champions classified as tanks. However, as of the Summer 2013 role-rework, Thresh is now classified as a Support/Fighter.
- Thresh is the second ranged champion to not use projectiles for ranged basic attacks, the first being Kayle.
- Thresh has, in fact, three different attack animations. In melee range, he hits directly with the sickle, at mid-range he swings his sickle in a circular and horizontal movement, and at long-range he uses it like a whip. Mid range is around 250-300 unit of distance.
- When reaching a certain amount of movement speed, Thresh's movement animation shows him gliding instead of running.
- When Thresh dances, he swings his scythe and his lantern like a pair poi (or kiwido or bolas), a side by side comparison can be seen here. The tricks Thresh does is a basic forward weave, a stationary forward windmill and an alternating behind-the-back butterfly.
- If Thresh throws his lantern and dances, he will swing only the scythe and the hook that the lantern rests on, instead of both the lantern and the scythe.
- With all his hooks, chains, many of the elements in his background, and the ability names "Keeper of Lost Souls" (former), "Flay", and "The Box" it is possible that Thresh's motif is a reference to franchise.
- Thresh's Death Sentence ability has a unique quirk; unlike most spells with a windup casting time, Thresh does not face the specific direction he is casting the ability until he actually sends out the hook. CertainlyT deliberately designed the ability to fit in with Thresh's theme of causing terror in his enemies. 
- Thresh is the first champion with an ability that can affect an allied champions position, namely Dark Passage.
- Thresh currently has the strongest slowing crowd control effect in the game, with The Box slowing by 99%.
- It may be noted though, that there is a hard cap for movement speed at 110. Therefore, any slow above 75% is not used to its full potential. For more information check movement speed.
- Thresh's login music is a reference to the nursery rhyme(s) "Rain Rain Go Away" and/or "Ring Around the Rosey".
- Nunu and Willump will drop one soul each, for a total of two souls!  It is a Hidden Passive.
- While similar, Sejuani and Bristle only drop one soul between them. This had led to a joke among the community that Sejuani has ginger hair in reference to the internet meme that gingers have no soul. 
- However, Katarina, Leona and Miss Fortune are redheaded and do drop a soul upon death.
- Sejuani and Bristle's case may also stem from the religious belief that animals have no souls, although apparently Yetis get to go to heaven.
- Although Zombie Brand and Haunted Maokai also have revival animations prior to Thresh's release, Thresh is the first champion to have the revival animation in his classic skin.
- Thresh is one of four champions that can, in theory, infinitely increase a stat by using an ability. Thresh can continuously add armor and ability power with his Damnation. The other three are Nasus, Sion, and Veigar.
- Unlike the other three, Thresh ability actually has a cap at 999,999 souls, at which point Thresh will have 749,999 bonus armor and ability power.
- The Box in the Death recap states "You have opened the box. Your prize: death".
- Thresh represents Gluttony as one of the Seven deadly sins.
- Thresh's quote "Come out and play!" is shared with Draven.
- Thresh's quote, "I am the thing under the bed," might be a response to Cho'Gath's "No, I do not live under a bed... fool!". It is also a reference to the - the original "Monster under the bed".
- Thresh shares a quote with Evelynn, Ezreal, Irelia, and Annie - "This way."
- Thresh and Caitlyn share a quote when they use their Ultimates - "Nowhere to hide"
- This skin may be a reference to from the franchise, and in turn a reference to the legend of . The skin shows some resemblance to the design of the character Davy Jones and his crew, with a similar dark aquatic motif. To 'send someone to Davy Jones' Locker' is a euphemism for sending them to the bottom of the ocean, effectively damning them; Deep Terror Thresh may be a twist on the legend of Davy Jones, with his lantern being the literal 'locker'.
- When Thresh recalls while using this skin, he brings out a chest and stands on it with a pose similar to .
- Thresh has a random second recall animation where, instead of pulling out a chest, he pulls out a tire and slumps in disappointment. It can be seen here.
- This skin has many references to the number three, likely due to being released as a promotional skin for the Season Three World Championship. Examples of this are Thresh's robe splitting into three tails, the top of his lantern being split into three parts and the presence of a crest with three lines on his back resembling the Roman numeral for three.
- It could be noted that Thresh has 3 'dreadlocks', possibly hinting to another reference to the number three.
- He shares this theme with Riven and Shyvana.
- Being a member of the Shadow Isles, Thresh has relations with numerous of its inhabitants. One of which are Karthus, Mordekaiser and Hecarim who he considers as friends.
- By stealing the soul of Lucian's dead wife Senna, Thresh has made himself an enemy of the Purifier.
- On the League of Legends website, both Thresh and Hecarim used to be listed as rivals with Ahri; this might be due to Ahri being a fellow harvester of souls which would interfere with the Shadow Isles' goals.
