All Fired Up!

Spyro hails from a rare line of magical purple dragons that come from a faraway land few have ever traveled.It's been said that the scrolls of the ancients mention Spyro prominently-- the old Portal Masters having chronicled his many exciting adventures and heroic deeds. Finally, it was Master Eon himself who reached out and invited him to join the Skylanders. Now calling Skylands his home, Spyro remains one of its most valued protectors, with evil facing a new enemy and the Skylanders gaining a valued ally.
