MAYOR BURGEMEISTER   (voiced by Martin Short)
Mr. Burgemeister is the Frankenstein’s next-door neighbor and Mayor of New Holland. A crotchety fuss-bucket, he is fanatical about his garden and can’t stand Sparky or anything else that threatens the perfection of his tulips. Mr. Burgemeister also asserts his authority over his niece Elsa Van Helsing by making her the reluctant star of his New Holland Dutch Day celebration.

MR. RZYKRUSKI (voiced by Martin Landau)
Mr. Rzykruski is the new science teacher at New Holland Elementary School. He has a thick, Eastern European accent and a unique way of explaining things. He connects with his students; however, parents misunderstand his passionate teaching style. Mr. Rzykruski serves as a mentor and inspiration to Victor, teaching him that science can do both good and bad things and that if a scientist does not put his heart into his experiment, there could be disastrous consequences.

NASSOR (voiced by Martin Short)
Nassor is highly intelligent, serious and intense. He takes a darker, more doomsday view on life than the other kids in New Holland. Nassor is instantly skeptical of the rumors surrounding Victor’s experiments with electricity, but once convinced, he is zealous in his quest to obtain Victor’s secrets.

WEIRD GIRL (voiced by Catherine O’Hara)
Weird Girl doesn’t fit in well with the other kids in New Holland, but it’s easy to see why—she delivers ominous pronouncements in a monotone voice with an unnerving stare. Her constant companion is her fluffy, white cat Mr. Whiskers, whose unblinking gaze matches her own. The other kids give them a wide berth—especially when Weird Girl rambles about Mr. Whiskers’ dreams.
