- Garen's new dance is a reference to Johnny Bravo's "Monkey Dance". A side by side comparison can be seen here.
- Contrary to popular belief, Garen yells "Demacia!" when using Courage and not during Judgment or Demacian Justice. This is due to many players using the two abilities together often in tandem.
- The phrase "Spin To Win!" originated from how easily some kills were obtained with Judgment. The most famous video about it is an animation of Garen spinning his sword to by .
- Coincidentally, much of Garen's kit is a possible basis for Wukong, mainly due to both characters having:
- A "Q" ability that scales over 100% in attack damage as an attack booster with an extra effect ( Decisive Strike silences with a movement speed boost while Wukong's Crushing Blow reduces armor by 30%).
- A passive ability that increases their defensive stats (with Garen's being a normal ability with not only percentage defensive boosts, but also with a damage reduction active while Wukong's only being a standard passive with flat defense boosts.)
- Point-and-click spells; Garen's can only target one champion with it and acts as his ult; Wukong's can hit two extra targets in range, moves him to said target(s) and acts as a normal ability instead.
- Wukong's Cyclone and Judgment involve a very similar spinning animation and the way their hits are racked up and how they can involve bonus movement speed during cast time and cancellation. A number of certain item actives and summoner spells can even be used during their cast times.

Cyclone is an ult itself that knocks up and can only be interrupted on command instead of with another ability.

- Garen's joke and his taunt were changed from the Test Realm to Release. The previous joke was "I know you're in that bush!"
- Garen's old joke was a reference to the commercials, which always end with the line, "You're gonna like the way you look. I Garen-tee it. Get it?"
