Professor E. Gadd

Professor E. Gadd, full name Professor Elvin Gadd (or sometimes Dr. E. Gadd; known as "Professor Oyama" in Japan), is a fictional character who has made a number of appearances in different Mario games, each time appearing as a mad, but friendly, gadget-inventing scientist. He always speaks in ambiguous gibberish, but the translation is always provided in a text box.

In Japan the professor is named after Nintendo game designer Yoshiyuki Oyama. The English name comes from "egad", a minced oath.

Professor 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 â€” 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. says he got his magic paintbrush from "a strange old man in a white coat". This is a fitting description of Professor E. Gadd, which is further confirmed when FLUDD seems to react in surprise to the statement. It is unknown if E. Gadd actually gave Bowser Jr. the Gaddbrush, or if Bowser Jr. stole it from him, but the latter theory is more likely. There is a symbol both on the Magic Paintbrush and FLUDD, showing a face and hairstyle similar to E. Gadd's, which seems to be the Gadd Science, Inc., logo. It appears on many of E. Gadd's other inventions.

In Mario & Luigi: Superstar Saga, the professor makes an appearance supplying the brothers with an array of accessories to help them along their way each time they drink at Starbeans CafÃ©, 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 future times, it would feature 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, E. Gadd provides the brothers a suitcase enhanced with artificial intelligence named Stuffwell to help them on their quest. The heroes later meet Young Prof. E. Gadd, who is researching the behavior of the Thwomps at Thwomp Volcano. After his lab is destroyed by the eruption of the volcano, he mentions his interests in studying ghosts, and that he would be buying a lab at the edge of Boo Woods, nodding toward his first appearance in Luigi's Mansion.

In Mario Party Advance, the player can use the coins earned in the mini-games to buy Professor E. Gadd's zany "Gaddgets". In Mario Party 6 Professor E. Gadd appears in his own board, E. Gadd's Garage. Players see him when they land on a ? space and usually get to try one of his inventions. In addition to this, E. Gadd's inventions are sometimes used as items in the Mario Part series.

Inventions
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. 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.

Super Poltergust 3001 An advanced version of a Poltergust 3000. It has the same functions 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.

Poltergust 4000 One of the vehicles used by Luigi in Mario Kart DS to race in. It is similar to the Super Poltergust 3001, though it does not float. The "barrel" of the car is the area Luigi sits on, and the nozzle rests on the ground. Emblems are placed on both sides of the barrel.

Game Boy Horror A portable device that bears a striking resemblance to the Game Boy Color containing a built-in camera which E. Gadd can use to 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. It is another portable device (this time bearing striking resemblance to a Game Boy Advance SP). It increases the likelihood of earning rare items in battle. It was originally going to be simply 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 The Flash Liquidizer Ultra Dousing Device, or FLUDD, 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. In certain ways, FLUDD functions much as Navi did in The Legend of Zelda: Ocarina of Time.

Magic Paintbrush 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 he stole it or 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 Used by Princess Peach to visit the past at the beginning of Mario & Luigi: Partners in Time. It is powered by the Cobalt Star.

Stuffwell An intelligent suitcase used by the Mario Bros. on their quest in Mario & Luigi: Partners in Time. Its purpose is to manage the brothers' inventory and display their current status. It also helps the brothers by activating the Shroob Saucers that you use in the game, and eventually near the end develops the ability to return to the past before you rescue Princess Peach. It is known to use large and overly complex words when he speaks, and upon ending its speeches, says "BACK TO ADVENTURE!"

Starbeans CafÃ© The cafÃ© in the beanbean kingdom, made by E. Gadd. Strangely enough, it does not have any toilets. At one point, E. Gadd puts up a larger-than-life-size portrait. Every time Mario and Luigi mix a new drink, E. Gadd visits.

Ghost Suit A pale blue jacket that, when worn, turns characters into a ghost. When E. Gadd wore this in Mario & Luigi: Superstar Saga, Luigi got scared and used the Poltergust 3000 to vacuum him up.

The Gaddlight A flashlight that is used to scare away Boos when they try to steal a Star or coins in Mario Party 4.

Hydrogush 4000 A large water pump used in Mario & Luigi: Partners in Time. It's not portable like the FLUDD, but it does have a lot of power.

DS Time Radar A handheld device that bears a striking resemblance to a Nintendo DS used briefly by E. Gadd to find Princess Peach in Mario & Luigi: Partners in Time. It has the ability to pinpoint which time period someone is trapped in. One of the Toads thinks he just made it up. Also, when Professer E. Gadd turns on his Hydrogush 4000, he uses a DS-like device.

E. Gadd Battle Machine Special parts that can be bought in the Super Duel Mode of Mario Party 5. They include the E. Gadd body, E. Gadd Jet, E. Gadd Engine and E. Gadd gun.

Coin Vacuum A vacuum from Mario Party 7. It is a capsule item exclusive to Wario and Waluigi. It doesn't look much like the Poltergust 3000. Rather, it is yellow and purple (much like the two characters that use it), and features the E. Gadd logo. It is used to steal coins from other players.

Surprise Wand A magic wand in Mario Party 7, which has the E. Gadd logo on it. It is exclusive to Boo and Dry Bones. It was used to turn the characters invisible, making them impervious to traps, and to give them double dice blocks for two turns.

E. Gadd's Garage E. Gadd's garage is the garage he had in Mario Party 6. He also keeps his numerous inventions there. It also appears as a Rare Mini-Game.

Gaddgets The Gaddgets appeared in Mario Party Advance. There were 80 total, and were very similar to the toys in the Wario Ware games.
