General
- Nidalee was the first of eight champions to have more than 4 abilities (the others being
Elise, 
Gnar, 
Heimerdinger, 
Jayce, Karma, Lee Sin, and Rek'Sai) - Nidalee, Elise, Gnar, Jayce, and Kayle are the only champions to be both ranged and melee.
- Nidalee is one of a few champions to have multiple textures in per skin (one for human form and another matching one for cougar)
- Nidalee was the first champion to feature a transformation ability (the others being Elise, Gnar Shyvana, and Swain)
- Nidalee has four running animations (human run, human brush sprint, cougar run, cougar brush sprint)
- Pounce was the first ability to feature a static cooldown (was removed in V1.0.0.124)
- Nidalee has a hidden passive called 'On the Prowl' (referencing cougars) which grants nearby lower-leveled allied champions 5 experience every 5 seconds.
- A maximum-range Javelin Toss has the second-highest damage of any single-targeted basic ability in-game (only surpassed by a fully-channeled Drain) and higher damage than many ultimate abilities.
- Nidalee was deemed overpowered/obnoxious in the Ultra Rapid Fire game mode (2014 edition) and was ultimately disabled in non-custom games.
- The game client's shop filters Nidalee as a Support despite her no longer having that tag as a secondary one.
Development
- Nidalee was released a day later than announced.
- Nidalee was rumored to have a special stackable damage over time that could be applied by all her damaging abilities as well as Prowl granting her stealth for 2 seconds when leaving brush in cougar form (both effects actually existed and were removed prior to her release)
- Nidalee used to have a bug where Primal Surge applied Swipe's damage (meaning she could kill her teammates if they were low enough)
Quotes
