Might as well throw my hat into the ring now with everyone's favorite ninja snooter, Fubuki!
Fubuki is an Ice Tarako (A species descended from her world's dragons) and the White Dragoon of Ice.
She has mastery over ice and snow along with a mastery of ninjustu for things like clones, stealth, can create ninja weapons out of ice, etc. She can also raise and lower her body temperature to expel freezing or superheated beams from her eyes or tornado-like gusts of frost or heat breath as well. Also that snoot's long enough to be a lethal weapon.
She's stoic and cool, with a hidden comedic and prank loving side as well. Tries a bit too hard to seem detached and cool and stoic, but does genuinely care a lot deep down. ALso she's very sensitive when someone brings up her snoot and its longth.
