Sparky is the main protagonist of the Tim Burton's animated film Frankenweenie based on the 1984 short of the same name. The dog of the scientist Victor Frankenstein, Sparky once lost his life in a car collision following a baseball game. In his attempt to bring his best friend back, Victor revived Sparky as an undead creature, bringing him back to life. Following his master in his undead form, Sparky saved Victor from hostile threats, including the mischievious dog Mr. Whiskers, though at the cost of losing his life again. After acknowledging the bravery of the two heroes, the townsfolk of New Holland granted Victor the chance to revive Sparky once again to honor their heroism.
Sparky also appears in the second Disney Heroes vs. Villains as one of the animal companions of the scientific users of the San Fransokyo Institute of Technology, assisting their masters in their fight against Syndrome and his allies.
