Lightning Rod is a celebrity among the Skylanders and joins Whirlwind and Sonic Boom to the roster of available air element characters. His primary attack, the lightning bolt, packs a powerful zap, while his secondary attack - grand lightning summoning - can take out a wider range of baddies.
Sunburn is part dragon and part phoenix, making him one of the most unique creatures in Skylands. Sunburn hails from the fire element and although he can breathe flames like the best of them, he can also teleport to protect himself. Sunburn rounds out the line-up of fire characters, joining Ignitor, Flameslinger and Eruptor.
Zook is a life character and comes locked and loaded with a bazooka attack. His hand-carved bamboo bazooka fires special explosive thorns and he can protect himself with his foliage barriers as he wanders throughout Skylands. Zook joins Stealth Elf and Stump Smash in the currently available line-up of life characters.
Skylanders Spyro's Adventure is now available at retailers for Xbox 360, PS3, Wii, PC and 3DS.
