Voltenstein is the mischevious old toy who enjoys haunting (and transforming) the toys. He joined as a character at the same time Zombie-Mode was released.
- Voltenstein got his name from a winning entry in a contest during open beta.
- Speaking of his name, Voltenstein is the only zombie with a name.
- There were rumors circulating that Voltenstein would be a fully playable character according to the Japanese sources. This may happen in the Japanese version.
- Voltenstein in-game generally has more health than the 'skimish' zombies he infects and makes, therefor being much harder to take down.
