A/N: After some given advice from I'm now properly going to introduce my character to some of you who don't know him.
Name: Eferno(Pronounced: Ee-Fur-no Meaning: Eternal Flame)
Powers: Elemental Powers, Dark magic
Eferno is not one to mess with in battle. He's vicous, lethal, cunning, and merciless. When he's not in battle, he would keep his distance from everyone, while also keep a serious demeanor and has little tolerate with silliness. He does however, have a caring attitude towards his sister.
Once before, Eferno was a Skylander and one of Eon's Elite Skylanders in a rebel force to overthrow the evil purple dragon king, Malefor. But during a battle with the Dark Army, the two forces were caught in a meteor shower and one of them, which is a dark crystal, strucked Eferno in the chest and fusing its powers with his, amplifying his power level beyond that of a purple dragon. With these new powers, he defeated Malefor and imprisoned him in the underworld, turning him into an undead dragon in the process.
But Malefor swore revenge, and he began by kidnapping Eferno and using his poisonous power in an attempt to make him his slave. When that didn't work, he targeted the only creature that means to Eferno more than anything in all of Skylands. His sister, who at the time was just an egg.
Enraged at the loss of his sister, Eferno tried to take matters into his own claws, but Eon and some Skylanders refused to aid him in his thirst for revenge, and instead, trapped him in another world, through a small crystal.
Eferno however, was more cunning than Eon had expected, for when the spell that imprisons him was being casted, Eferno had invisibly casted a similar spell on the Skylanders who battled him that day, so that they would be turned into crystals and would be scattered across the universe when he is trapped.
During his years trapped, Eferno watches over his little sister, Cynder, and observes how she had been mistreated as a slave of Malefor and during her time with the Skylanders, with some refusing to trust her, while also, observing how so many innocent creatures, dragons, elves, and humans alike were all given the same treatment as his sister, fueling his anger and his desire to be free even further, which he later succeeded with the help of Nick, a black dragon, and Vathek, an undead dragon.
