He was voiced by the late Roddy McDowall.
He returned to a normal hamster due to being despliced by the gene splicer in "Brainwashed Part 3". Because of this, Snowball was never seen again, meaning he was one of the few characters in the Animaniacs/Pinky and the Brain universe to be permanently written out.
Snowball is evil, cruel, manipulative, scheming, angry, mean, rude, uncaring and aggressive. Snowball is constantly lying, so he could get what he wants such as when he was lying to Pinky about how The Brain was just using him by stealing ideas and calling them his ideas. Then, he later said that he was using Pinky just to get revenge on The Brain.
Snowball is highly intelligent much like The Brain.
Unlike The Brain, Snowball never had any good intentions and he only cares about himself.
He also loves Billie like how the Brain does.
Snowball and the Brain both have similar personalities and actions as they both act abusive, angry and mean, they both want to take over the world, they both love Billie, and both of their heads are big due to the gene splicer. But, the only differences are that the Brain sometimes has good intentions despite abusing and threatening Pinky and thinking of evil plans, and Snowball does not have good intentions, meaning Snowball is more cruel and evil than Brain.
Although Snowball is a villain, he is a neutral character when he appears as a normal hamster.
When Snowball and Brain were young, they both used to be friends, but when they become older and when they were despliced by the gene splicer, Snowball betrayed Brain, and they both become enemies after Snowball was kicked out of Acme Labs.
After Brain explains the story about how he and Snowball used to be best friends, Brain mentions that Snowball wanted revenge on humankind.
Just like The Brain and Pinky, Snowball also wants world domination. Pinky and Brain are sometimes forced to foil his schemes.
Unlike Brain, Snowball never had a sidekick to help him.
Snowball is an orange hamster with black eyes, a red nose, pink hands, pink feet and a stubby tail. While most of his fur is orange, his stomach is white. Just like Brain, Snowball's head is big.
Snowball is mostly naked due to being an animal, but he sometimes wears clothes.
Despite his name being Snowball, his body is not white except for his stomach.

- It is unknown how Snowball survived from drowning in a waterfall in other episodes as Snowball fell into a waterfall in a Pinky and the Brain episode called Welcome to the Jungle when Brain tried to save him.
