SKT1 Zyra designed by Morello, who came up with the idea. Coronach and CertainlyT did most of her design.
SKT1 Zyra is voiced by Karen Strassman, who also voices Cassiopeia, Fiora, Shyvana, and Elise.
Morello stated this champion was inspired by Sadida's Shoe, a character class from the Dofus/Wakfu games.
SKT1 Zyra's Rise of the Thorns is similar to the Sadida's Still Life. Sadida revives as an Ultra-Powerful Doll, while SKT1 Zyra turns into a large plant.
SKT1 Zyra's Rampant Growth is similar to Sadida's Doll Seeds, as both types of seeds have different forms depending on the spells used on them.
SKT1 Zyra's Grasping Roots is similar to Sadida's Bramble, as both cover the enemy in thorny roots and deal damage.
SKT1 Zyra is the 4th champion to have an ability that allow the champion to attack after death. SKT1 Zyra's ability is Rise of the Thorns, while the others are Karthus's Death Defied, Kog'Maw's Icathian Surprise and Yorick's Omen of Death.
SKT1 Zyra's co-creator, CertainlyT, hinted in the LoL forums that SKT1 Zyra has three hidden passives. They're confirmed to be:
Sion: When either Sion or SKT1 Zyra kills the other, they receive a bonus +2 gold (a reference to Plants Vs. Zombies).
Maokai: Maokai gets +1 movement speed if he's on the same team as SKT1 Zyra.
Leona: Leona's passive causes SKT1 Zyra to increase in size for a short time.
SKT1 Zyra's dance resembles the basic movements for the dance "Cha-cha-cha".
SKT1 Zyra's passive was called Queen of Thorns before being changed to Rise of the Thorns.
SKT1 Zyra is the fourth champion to have a special animation while using Recall or Teleport in which she looks up and extends red vines in her arms touching the ground.
SKT1 Zyra's name resembles the word "Zahra" in Arabic, which means 'blooming flower'.
SKT1 Zyra's name resembles the word "Zera" in Hebrew, which means 'Seed'.
SKT1 Zyra is the fifth champion to be able to transform, albeit hers has a different mechanic than Elise, Nidalee, Shyvana and Swain.
SKT1 Zyra's passive, Rise of the Thorns, and ultimate, Stranglethorns, have a cyan hue instead of green in her Champion Spotlight.
SKT1 Zyra's Rampant Growth is possibly a reference to the Magic: The Gathering card of the same name.
SKT1 Zyra's earring has some resemblance to the icon of the Zerg Swarm in Starcraft 2 - a comparison can be found here.
SKT1 Zyra is the second champion who shares her title with a skill name, after Vayne.
SKT1 Zyra was speculated to be a stealth champion since her release went along with the new stealth system.
