Electricity is one of Spyro's many different Elements he has the ability to command. This ability was first seen in the game, Spyro: Enter the Dragonfly, given to him by the Dragon Spirit to help save the missing Dragonflies. It makes a reappearance in Spyro 2: Season of Flame, and in A Hero's Tail, unlocked after defeating Gnasty Gnorc. In A Hero's Tail, electricity powers up machines that are used to help Spyro move across large gaps or raise up to large heights. The electricity powers are also a slight more powerful than the fire breath but the electricity powers take longer to defeat enemies than the fire breath.
The water dragon Zap wears a special harness that allows him to store electricity. He can then discharge it as a breath attack, which can be used on its own or to electrify the slime trails he can make.
Cynder, an Undead dragon, is another Skylander who can breathe electricity.
Wham-Shell, another water character, can manipulate electricity using his mace.
The Air Skylander, Lightning Rod, can summon electricial discharges from the cloud he is in and also bring down bolts of lightning to strike down from above.
Whirlwind can summon tempest clouds, which discharge electricity when foes touch them.
