Disney has scattered across various news sites some exclusive downloadable character posters and bios from Tim Burton’s upcoming black-and-white, stop-motion film, Frankenweenie.

Cinema Blend brings us posters that showcase the film’s two main characters: Victor and his dog, Sparky. Shock Till You Drop reveals two of Victor’s school chums: Bob and Toshiaki. The Disney Movie News Blog brings us posters of The Frankensteins and Bob’s Mom. Just Jared gives us a peak of Elsa Van Helsing and her pet poodle, Persephone.

Here’s the main star, Victor (Charlie Tahan), along with his character desciption:

Victor Frankenstein 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.

Or is the main star Sparky?

Sparky is a devoted and playful bull terrier 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.

Here’s Bob (Robert Capron):

Bob is a momma’s boy who is the brawn to Toshiaki’s brains. He is agreeable and never mean-spirited, but on the flip side he’s easily led and gullible. Bob follows Toshiaki everywhere, but is the first one to run to Victor for help when he gets in over his head.

Next is Toshiaki (James Hiroyuki Liao):

Toshiaki is over-achieving and mega-competitive. He delights in beating Victor at his own game and like a power-hungry, mad scientist, Toshiaki will stop at nothing to win the top prize in the school’s science fair – even if it means stealing Victor’s ideas to do it.

Here are Mr. & Mrs. Frankenstein (Catherine O’Hara & Martin Short):

Mr. Frankenstein is a travel agent, friendly and social, who likes to dispense roundabout advice to his son. He is proud of Victor’s accomplishments, but is concerned he doesn’t have any friends other than Sparky. He would prefer his son be more social and encourages him to join the baseball team. Mr. Frankenstein has a playful and loving relationship with his wife, Victor’s mom.

Mrs. Frankenstein is a loving and supportive mother who encourages her son’s scientific pursuits, even when her kitchen appliances end up in his attic lab. She is an avid reader and loves to watch movies with her husband and enjoys the company of her family and her books.

Bob’s Mom (Conchata Ferrell):

Bob’s Mom is a plump, suburban housewife who is prone to panic and hysteria when things go awry. She has very simple, stereotypical views on life, which she isn’t shy about sharing with the community. She dotes on her son Bob and believes her actions, though often misguided, are in his best interest

Elsa Van Helsing (Winona Ryder):

Elsa is a soulful and somber classmate of Victor. She lives next door to him with her tyrant uncle, Mayor Burgemeister, who forces her to be this year’s “Little Dutch Girl” at the town’s celebration of Dutch Day. Elsa also has a beloved pet, her poodle Persephone (also pictured inside), and truly empathizes with Victor when he loses Sparky.

And lastly, the poodle Persephone:

Persephone is a perfectly groomed black poodle with an enormously large poof of hair on her head. She is curious and flirtatious with Sparky and fiercely loyal to Elsa, her owner. When Persephone and Sparky first meet in the backyard, the attraction is instantaneous and electrifying.
