Euginie is the Air Portal Master and one of the default Portal Masters in Skylanders: Ring of Heroes. She is the Treasure House of Knowledge. In the game's 2.0 reboot, she is the first Portal Master to be unlocked.
I've done sorting fancastings for every other popular mon series out there, might as well do this one. Sort characters from series other than Bakugan by what Bakugan attribute they'd have!
