Victor Frankenstein (voiced by Charlie Tahan) is a clever and industrious 10-year-old boy who is inspired by science. He lives with his parents and dog, Sparky, in the town of New Holland. Victor immerses himself in making films and inventing in his attic workshop. When Sparky dies in a car accident, Victor uses scientific ingenuity to bring him back to life.

Sparky is a devoted and playful bull terrier dog whose sense of curiosity is matched only by his beloved owner, Victor. Sparky enjoys chasing after balls and being the star of Victor’s homemade movies. He exudes tons of energy and enthusiasm, which even his untimely death doesn’t diminish.
