- Darius was designed by CertainlyT.
- He was in production long before the Journal of Justice Issue was released with a character of similar looks. 
- Darius is voiced by Chuck Kourouklis.
- Darius' name derives from the Persian word "dariush", which means "kingly".
- Darius was also the name of a Persian king who was also called "Darius the Great".
- Darius was the first champion to have a special animation while using Recall or Teleport, in which he lifts his axe upward and looks up.
- Darius and his brother Draven are the first related champions to be released back to back. Coincidentally, they both have the same level of attack speed.
- Darius is one of the 9 champions who do not have a single skill that scales off ability power; along with Zed, Draven, Garen, Kalista, Olaf, Riven, Talon and Vayne. However Darius is the only one among them all that has an ability that causes magic damage, his passive that scales off attack damage to deal magic damage.
- Darius doesn't care for titles or privileges―he simply uses what power he attains in the service of Noxus 
- Similarly, he isn't a crazed, bloodthirsty maniac, contradicting what people would believe. He's more of a cold-blooded killer, moving through the battlefield with powerful, but precise, movements, striking with deadly force where it matters most. He takes pride in combat, but there's no primal bloodlust that he constantly needs to sate. Unpredictable sadists don't always make the best commanders .
- When his ultimate, Noxian Guillotine, is used, the model of his classic skin will change to be spattered with blood.
- Darius' Noxian Guillotine is referred to as "Sudden Death" within the game's files.
- Darius' Crippling Strike is referred to as "Hamstring" or "Noxian Tactics" in some cases within the game's files.
- There used to be a buff icon when Darius' movement speed was increased through Hemorrhage, with the following text: "Aggression - The carnage of war enlivens Darius, increasing his movement speed."
- Both of Darius' jokes have him trying to spin while shouting "Noxus!" as a reference to Garen and the popular "Spin-To-Win" joke. However, Darius has difficulty performing the move and, in one of said jokes, wonders how Garen does it.
- Darius shares a quote with Quinn. "Stay alert."
- He shares a quote with Vi: "Get dunked"!
- He has two similar taunts for Fiddlesticks and Nocturne: "Spooky".
- He shares a quote with Draven and Katarina: "Too easy".
- Many of his quotes have the word "Dunk" in it.
- All of his quotes when he is buying items have an advertisement twist.
- His joke: "Nothing but dunk", is a direct reference to Michael Jordan's Big Mac advertisement.
- Noxus Air is a reference to Nike Air shoes, ones that many basketball players wear.
- The name could be specifically referencing Nike's Air Jordan line of shoes.
- It currently has the most taunts ingame.
- His taunt for Ashe, "Dat fail", is referring to how many players say "Dat Ashe" as a joke for how Ashe sounds like the vulgar slang for butt, (ass), and how people say "Dat ass".
- His joke: "I'm in the business of dunking, and business is good." is referring to the Megadeth album Killing is my Business, and Business is Good.
- In his splash art, Beatrice ( Swain's raven) appears on the battlefield.
- In Darius' classic splash art, a shadowy figure can be seen who resembles Aatrox.
- Though this can also be a regular Noxian soldier, as the ones illustrated in the Journal of Justice look very similar to the figure.
- This skin has a close resemblance with Tyrant Swain [S|L], possessing copper-trimmed grey armor inlay with green stones of similar shade to Tyrant Swain's ability VFX, and dark red cloth. The correlation is further strengthened by this skin's raven motif, seen on his raven-headed belt buckle, several claw-like ornaments, and in the skin's splash art, several green stones on his axe aligned in such a way as to mimic Beatrice ( Swain's multi-eyed raven).
- This skin gives off a green glow whenever he uses an ability.
- In the splash art, Darius can be seen fighting Frost serpents, feared beasts originating from Lokfar and who are mentioned in Olaf's lore.
- He bears a striking resemblance to as from .
- He shares this theme with Woad Ashe and Woad Scout Quinn.
- When using this skin, Darius's abilities emit a frost-like effect.
- This skin was a fan suggested skin and is inspired by numerous memes that portray Darius's Noxian Guillotine as a Basketball dunk.
- This skin refers to the job that Darius might have had, similar to Primetime Draven.
- On the back of Darius's shirt, a symbol of Sion's axe (and as well as the Noxus Crest) can be seen.
- In the Taiwanese client, the skin is called "Slam Dunk Darius", a reference to the famous Japanese animation/comic, "Slam Dunk".
- Many of his animations are influenced by famous basketball moves.
- In his walking animations, Darius dribbles a basketball.
- When he ults and Recalls Darius does a Michael Jordan slamdunk.
- Darius has formed an alliance with Jericho Swain, seeing him as a leader with the mind and determination to bring Noxus to glory. With Swain, Darius works to unite the nation behind his vision of true Noxian strength.
- Darius's view of Swain is almost entirely pragmatic. He will loyally follow Swain's orders, but it's more chain-of-command than father-son relationship.
- Darius is somewhat suspicious of the Black Rose. He understands that they've used deception and trickery to help in Swain's rise, but he's concerned that he doesn't know the depths of their conspiracies.
- Darius doesn't have much respect for Necromancy: if one died in battle, they didn't deserve to survive.
- Although, on the other hand. Darius definitely would have looked up to Sion's legacy, had it not been tarnished. When Darius sees Sion, he sees what he might become the day his strength fails him. It's not a fate he approves of.
- He has no personal issues with Garen - he thinks the man is a fool, following a meaningless code of "honor", but he doesn't have a burning hatred for him. He would relish killing Garen in battle though, proving Noxian strength triumphs over the most iconic image of Demacian values .
- Darius is Draven's older brother. The two together were known as "The Blood Brothers".
- Family bonds can be strong, and a family can become a foundation of strength. It can become easy for weak people to use their family name as a crutch, though, resulting in the kind of self-serving aristocracy that Darius sought to topple. It's clear that Darius felt a responsibility to keep his brother safe and alive - whether that was from love or pragmatism remains to be seen.
