Gnar x Shyvana
Why isn't this a thing yet?
It could be called Gnarvana, or ShyGnar!
Shyvana is a Half-Dragon literally fueled by her rage, possessing questionable emotional stability.
Gnar is an adorable little plushy also possessing rage issues.
On a power-level, Mega-Gnar and Dragon-Shyv are two characters who could potentially handle eachother in a fight if their anger got the better of them.
From Shyvana's point of view, she can sympathize with Gnar, place herself in his shoes. And yet, he's still hyper and happy when not raging. She can use him as an example of how not to let her rage control her. He can be her little plushie.
From Gnar's point of view; Big Dragon lady takes care of him and shows him affection. And he's adorable.
