Okay, talking in third person is starting to get pretty annoying now...
Anyways...

Jet-Vac
Jet-Vac was the greatest, most daring flying ace in all of Windham. He was given his magical wings when he was young, as was the tradition for all Sky Barons. But when his homeland was raided, he chose to sacrifice his wings to a young mother so she could fly her children to safety. This act of nobility caught the attention of Master Eon, who sought out the young Sky Baron and presented him with a gift - a powerful vacuum device that would allow him to soar through the skies once again. Jet-Vac accepted the gift with gratitude, and now daringly fights evil alongside the other Skylanders.
Pop Fizz
No one - not even Pop Fozz himself - is quite sure who Pop Fizz was before he became an alchemist. After many years of experimenting with magical potions, his appearance has changed significantly. In fact, no one even knows his original color. But it's common knowledge that he is a little crazy, his experiments are reckless, and the accidents they cause are too numerous to measure. Understandably, he has had a difficult time finding lab partners, or anyone who wants to be near him. In hopes of making himself more appealing, he attempted to create the most effective charm potion ever - but that just turned him into a big, wild berserker. Or maybe that's how he envisioned the potion working in the first place...
Tree Rex
Long ago before the Giants protected Skylands, Tree Rex was a majestic tree living peacefully in the ancient woods. But this tranquil peace came to an end when the Arkeyans built a nearby factory to produce war machines. After years of his soil being poisoned by the magic and tech waste from the factory, he mutated into who he is now - a powerful Giant who will crush anything that threatens the natural order of things.
