Professor Voltage is an inventor who appeared in 5706 LEGOLAND video game.
You may not have realised, but every LEGOLAND Park has it's own resident scientist. It's their job to invent fantastic attractions and cool rides. Where do you think we got all that amazing stuff from? The Professor has a mysterious past but his inventions, when they work, speak for themselves. The Professor has even developed a ‘Ride Chamber’ which uses special blueprints to make your Attractions in double quick time! The Professor has developed all kinds of weird stuff, including the famous LEGO Mindstorms robots and the cool Destructa Bricks in LEGO Creator! One thing to watch out for though is that he is easily distracted by his own curiosity and that can lead to all kinds of trouble…
- Professor Voltage appeared in beta versions of LEGO Racers 2, where he acted as a guide to the player. This role was given to Sparky in the final game. Despite this, Professor Voltage's model, textures, and icon are still present in the game's assets, and through file modification or memory editing it is possible for the player to play as him. His appearance in LEGO Racers 2 was quite different from his others, with gray hair, altered face and shirt detail, and brown pants.
- Professor Voltage also appeared in several LEGO Adventures! Magazine comics. In one comic, he unveiled his latest invention, an invisibility ray, only to have it briefly stolen by the Brickster. He was also briefly mentioned in the LEGO Island Comic Adventure "The Stolen Painting", where Pepper Roni and Luna Rom used his boat to reach Knights' Kingdom Island.
- Professor Voltage is the grandfather of Veronica Voltage, a champion racer whom appears in LEGO Racers.
