Shyvana's ultimate, Šablóna:Ai, is the only non-toggle champion ability in the game that is not cooldown based.
Shyvana's dance is from the music video RIVER by the Japanese idol group Šablóna:W. A side-by-side comparison of the dance can be seen here.
Shyvana's lore was changed after release, removing references to being attacked by a mob and instead having Šablóna:Ci save her from the wrath of the dragons. This change was done because it was felt that the original lore did not make it sensible for her to join Demacia.
Shyvana was the first champion since Šablóna:Ci to not receive a League Judgement. With the exception of Šablóna:Ci, no other champion since then has received a Judgement either.
Shyvana's rage system was mislabeled as "Dragon's Blood" on her mechanics preview.
Ironscale Shyvana is a reference to the Šablóna:W worn by warriors of different cultures.
Scale armor is often associated with Šablóna:W in various fantasy genres. This is most likely due to how the individual metal scales are overlapped with each other, resembling the fictional scales of a dragon.
Moved by Shyvana's plight, Šablóna:Ci assisted her in slaying the mighty dragon that killed her father. After the battle, Jarvan IV offered Shyvana a place as a noble warrior in the ranks of the Demacian Elite Guard. Out of gratitude and necessity, Shyvana accepted.
