E. Gadd

Professor E. Gadd, full name Professor Elvin Gadd (or sometimes Dr. E. Gadd; known as "Professor Oyama" in Japan) has made a number of appearances in different Nintendo games, each time appearing as a mad, but friendly, gadget-inventing scientist.

Professor E. Gadd with the Poltergust 3000 as seen in Luigi's Mansion

E. Gadd debuted in Luigi's Mansion as one of the main characters. Luigi enters the mansion and is saved from ghosts by a strange old man wielding a vacuum cleaner. Professor E. Gadd reveals he lives in a house near the mansion, where he researches his favourite subject &mdash ghosts. Luigi explains his brother Mario is missing within the house, and the professor decides to help Luigi by giving him two of his inventions, the Poltergust 3000 and the Game Boy Horror, the professor continues to help Luigi throughout the game, giving him help and tips.

In Super Mario Sunshine, when Mario finds FLUDD, it says: "Thank you for purchasing this item from Gadd Science, Inc." Later, Bowser Jr. appears and says: "This is my magic brush. When I draw with it, all my wishes come true. A strange old man in a white coat gave it to me." This is a fitting description of Professor E. Gadd, which is further confirmed when FLUDD seems to react in surprise to the statement. There is a symbol both on the Magic Paintbrush and FLUDD, showing a face and hairstyle similar to E. Gadd's.

In Mario & Luigi: Superstar Saga the potty professor makes an appearance supplying the brothers with an array of accessories to help them along their way, after they try each drink at Starbeans Cafe, a coffeehouse that he owns. However, it has been found that originally, the game was only going to feature Professor E. Gadd once, the first time you get a drink. In all of the other ones, it features a different character. These characters are Wario, Samus Aran, Fox McCloud, Link, Excitebike racer and Captain Olimar.

In Mario & Luigi: Partners in Time the professor debuts his newest invention to the Mushroom Kingdom, a time machine. However, when Princess Peach ends up stuck in the past, the E. Gadd provides the brothers a suitcase enhanced with artifical intelligence named Stuffwell to help them on their quest.

In Mario Party Advance, the player can use the coins earned in the mini-games to buy Professor E. Gadd's zany "Gaddgets".

Inventions of Gadd Science, Inc.

The following is a brief list of some of E. Gadd's inventions that have appeared:

• Poltergust 3000 - A modified vacuum cleaner designed to entrap ghosts. It also has a 'blow' function which allows it to expel elements it sucks up such as fire, water and ice. it also has a flashlight attachment. Luigi uses this in Luigi's Mansion to defend himself from the many ghosts, it also makes a return in Mario Power Tennis where Luigi uses it as his defensive Power move, using its suction power to retrieve the ball.

• Poltergust 3001 - An advanced version of a Poltergust 3000. It has the same funtions as the Poltergust 3000, but is much larger because it can be ridden on. When ridden, it hovers over the ground. It can move at high speeds. E. Gadd uses briefly it in Mario & Luigi: Superstar Saga.

• Game Boy Horror - A portable device (that bears a striking resemblence to the Game Boy Color) containing a built-in camera which E. Gadd can watch the action from the safety of his lab and contact Luigi. It also stores data including a map and anything Luigi has collected, and contains a special radar called the Boo Radar to find hidden spherical objects.

• Game Boy Horror SP - The upgraded version of the Game Boy Horror, given to Mario by E. Gadd in Mario & Luigi: Superstar Saga. Originally going to be merely the Game Boy Horror.

• Ghost Portrificationizer - A large machine which works in conjunction with the Poltergust 3000, certain ghosts captured can be entrapped in portraits to be hung in E. Gadd's gallery. The machine also works in reverse, which was utilized to free Mario from the painting he had been trapped in by King Boo.

• FLUDD (Flash Liquidizer Ultra Dousing Device) - This is a water-spraying backpack used by Mario in Super Mario Sunshine, it has various nozzle attachments which can be collected by breaking open boxes with E. Gadd's logo on the front. FLUDD also has notable artificial intelligence and the ability to communicate with a voice.

• Magic Brush - This is used by Bowser Jr (as Shadow Mario) in Super Mario Sunshine. It is a large paint brush with the ability to paint various colours and even create enemies. It is unclear why the brush was made as well as why it was given to Bowser Jr., though some fans claim E. Gadd was tricked by Bowser Jr. using his Mario costume. In Mario Power Tennis Bowser Jr. uses his Magic Brush to perform special moves.

• Time Machine - This is used by Princess Peach to visit the past at the beginning of Mario & Luigi: Partners in Time.

• 'Stuffwell - An intelligent suitcase used by the Mario Brothers on their quest in Mario & Luigi: Partners in Time. Its purpose is to manage the brother's inventory and display their current status.
