The road trip gave me the time I needed to study up on the Luna Queen. Born pennyless she was fascinated by the fireworks rich noblemen set off every New Year’s. She spent a decade learning the art. But when she tried to offer her fireworks to the noblemen, they couldn’t see past her shabby clothes and chased her away. Humiliated, the Luna Queen took revenge on those who shunned her by using the very tools of her art for crime. The Fiendish Five recruited her as their demolitions expert, and from then on her explosive touch became feared worldwide. She’s rumored to be perfecting some new firework technique high in the unstable Kung-Lung Mountains of western China.

Firey wings!  
Booming stomp!  
Hooves of thunder!

sly cooper in: luna in the sky

Hoof of Flames!

she’s a firebender!!!!!!!!!!!

This fits perfectly, especially with Panda King’s split personality.

Luna with fireworks. Sounds fun.

Precisely. SO glad I chose her instead of Sombra, which would have only been because they both have King in their names.

Huh.
 
I could actually see it.
 
A foe that the main character defeated a long time ago, who was repressing their memories of anger and eventually came to that hero’s side.
