Professor Elvin Gadd (often referred to as, Prof. E. Gadd, or Professor E. Gadd) is a Professional Ghost Hunter that appears as a Main Character in Luigi's Mansion, Luigi's Mansion: Dark Moon, and as a Amiibo Costume in Super Mario Maker.
Luigi's Mansion series Edit
Luigi's Mansion Edit
in Luigi's Mansion, 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 favorite subject: 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.
Luigi's Mansion: Dark Moon Edit
After a few years of absence, Professor E. Gadd appears in the game Luigi's Mansion: Dark Moon. In the game, E. Gadd takes up residence in Evershade Valley after learning that the ghosts there are friendly. Eager to examine ghosts without fear of being attacked by them, he sets up a laboratory in the Gloomy Manor and a Bunker close by the mansion. There, he begins researching the ghosts of the five mansions that populate the valley, and sends his five Toad assistants to the other four mansions in the valley to examine the ghosts there. At first, the resident ghosts welcome him and assist him in his lab, but when King Boo arrives and destroys the ghost-pacifying Dark Moon that hangs over Evershade Valley, the ghosts start running amok and destroy E. Gadd's equipment. He flees to his nearby Bunker and enlists the help of Luigi — who has now taken up residence in his new Grade D mansion from the previous game — to help rebuild the Dark Moon and calm the ghosts once more. E. Gadd was later revealed to have been unintentionally and indirectly responsible for King Boo's return, as he had sold his portrait in a garage sale, thus ensuring his escape.
In this game, E. Gadd has made an upgrade of his Poltergust 3000 from the last game: the Poltergust 5000. This new Poltergust uses a Strobulb to stun ghosts, rather than the flashlight used with the Poltergust 3000. Professor E. Gadd also introduces three new inventions: the Pixelator, a machine that turns Luigi into pixels and transports him to and from the different mansions, the Dual Scream, a device that resembles a Nintendo DS and is capable of communication, and the Dark-Light Device, which allows Luigi to see invisible objects.
Super Mario Sunshine Edit
Although Professor E. Gadd does not appear in Super Mario Sunshine, when Mario initially finds F.L.U.D.D. at the Delfino Airstrip, 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." Bowser Jr. uses the paintbrush to frame Mario and get him away long enough for himself to go in and kidnap Princess Peach. This is a fitting description of Professor E. Gadd, which is further confirmed when F.L.U.D.D. seems to react in surprise to the statement. It is unknown if E. Gadd actually gave Bowser Jr. the paintbrush, or if Bowser Jr. stole it from him, though the latter theory is more likely. There is a symbol on both the Magic Paintbrush and F.L.U.D.D. 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, as well as the boxes for F.L.U.D.D.'s nozzle upgrades.
Mario & Luigi series Edit
Mario & Luigi: Superstar Saga Edit
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 Cafe, a juice shop that he owns. However, it has been found that originally, the game was only going to feature Professor E. Gadd once, the first time Mario and Luigi get a drink; in all of the future times, different characters would have appeared. These characters are Wario, Samus Aran, Fox McCloud, Link, an Excitebike racer, and Captain Olimar. He also appears in the 2017 remake of this game where he even foreshadows his role in Partners in Time.
Mario & Luigi: Partners in Time Edit
E. Gadd has a much larger role in Mario & Luigi: Partners in Time, where the professor debuts his newest invention to the Mushroom Kingdom, a Time Machine. Princess Peach, accompanied by Toadiko, and Toadbert, volunteers to be a passenger on its maiden voyage. However, when the time machine returns, it is not the trio that left but rather a strange creature that emerges instead. After the bros. defeat it, Gadd places the creature inside a tube of fluid, keeping it alive and allowing him to study it.
Out in the courtyard, Mario and Luigi discover a hole in the ground; E. Gadd elaborates that this hole is a Time Hole, a rip in the time-space continuum, which was created by the use of the time machine. After Luigi falls in the hole and Mario heads in to save him, the professor sends Stuffwell, a sentient suitcase, through to help them. For most of the rest of the game, E. Gadd is seen studying the Junior Shrooboid defeated earlier.
At Thwomp Volcano, Mario, Luigi, and their baby counterparts come across a younger Professor Elvin Gadd, who is studying Thwomps. During this time, though, the volcano erupts, with several Thwomps falling in and destroying the laboratory. One threatens to explode, and must be put out; Mario and Luigi do this by having Mario drink water and Luigi hammering him to spit it at the Thwomp, dousing it. Witnessing this event in the past causes inspires E. Gadd of the present to invent the Hydrogush 4000, a massive water pump. Mario and Luigi then have him pump water through the time hole leading to Thwomp Volcano to douse the mountain. After his lab is destroyed by the eruption of the volcano, young E. Gadd 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.
After discovering that baby tears are the Shroob's weakness, Mario, Luigi, and Princess Peach relate this to the professor. E. Gadd then uses the Hydrogush to pump a liquid similar to Baby Luigi's tears through the time holes, removing the Shroobs and restoring any Shroobified characters.

The description of his trophy talks about his role within Luigi's Mansion: Dark Moon, describing the events of the Dark Moon being shattered, and the professor calling upon Luigi to aid him. E. Gadd is referred to by his full name - Professor Elvin Gadd - in North America, while PAL regions have his first name abbreviated.

It is worn on Mario's back, and has various nozzle attachments which can be collected by breaking open boxes with E. Gadd's logo on the front. F.L.U.D.D. also has notable artificial intelligence and the ability to communicate with a voice. In certain ways, F.L.U.D.D. functions much as Navi did in The Legend of Zelda: Ocarina of Time.

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 Game Boy Horror SP is a 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 a striking resemblance to a Game Boy Advance SP. It always gives the Bros. access to rare items in battle.

- E. Gadd's Vault
A vault E. Gadd made to contain the ghosts of Evershade Valley and the ScareScraper in Luigi's Mansion: Dark Moon.

The Magic Paintbrush is used by Bowser Jr. (as Shadow Mario) in Super Mario Sunshine. It is a large paint brush with the ability to paint various colors, though this magic paint can change the landscape, create portals, and create obstacles or 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, Mario Hoops 3-on-3, Mario Super Sluggers, and Mario Sports Mix, Bowser Jr. uses his Magic Paintbrush to perform special moves.
A device that allows E. Gadd to detect and measure distant paranormal signals and pieces of the Dark Moon from his Bunker in Luigi's Mansion: Dark Moon.
E. Gadd uses the Pixelator to send Luigi, and his Toad assistants, from the various mansions in Luigi's Mansion: Dark Moon.
- Poltergust 3000
The Poltergust 3000 is 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 Shot, using its suction power to retrieve the ball. It also appeared as trophies in Super Smash Bros. Melee and Super Smash Bros. Brawl. The Poltergust 3000 is also used by Luigi inMario Sports Mix for his special ability.
- Super Poltergust 3001
The Super Poltergust 3001 is an advanced version of a Poltergust 3000. It has the same functions as the Poltergust 3000, but is much larger thereby allowing it to be ridden on. When ridden, it hovers over the ground. It is capable of moving at high speeds. E. Gadd briefly demonstrates the invention and uses it inMario & Luigi: Superstar Saga.
- Poltergust 4000
The Poltergust 4000 is 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.
- Poltergust 5000
A vacuum that Professor E. Gadd creates for Luigi to vacuum up more ghosts in Luigi's Mansion: Dark Moon. It is a successor to the Poltergust 3000 and it creates a large circular sucking motion rather than the small sucking motion from the first game, making it a lot easier to defeat multiple ghosts at once. There are also different accessories designed for the Poltergust 5000, such as the Strobulb and the Dark-Light Device.
- Robo Mario
This robotic entity of Mario races against players in the Rainbow Cup challenge game in Mario Kart Arcade GP 2. It spawns an infinite number of items and changes items depending on its place.

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 are used in the game, and eventually near the end develops the ability to return to the past before rescuing Princess Peach. It is known to use large and overly complex made-up words when he speaks, and upon ending its speeches, says "BACK TO ADVENTURE!"
- 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. It breaks at the beginning of the game but is repaired after the Shroobs are defeated.
- Vacuum Orb
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.

- In The Super Mario Bros. Super Show! episode "Robo Koopa", there is a scientist named Dr. Nerdnick who bears a passing resemblance to E. Gadd due to their similar appearance and the fact that they both speak in incomprehensible gibberish.
- In Super Smash Bros. Brawl, one of the names that can appear when a player presses the random button in naming their custom stage is "EGADD".
- Glasses with swirls are often seen in Japanese media that are a feature E. Gadd shares with Professor Frankly, Fawful, Francis, and Iggy Koopa.
- Occasionally, Professor E. Gadd's voice-overs will include "Oyamaa", which is both his Japanese name and an exclamation of surprise. This happens even in overseas releases.
- Professor E. Gadd is one of the few characters in the series who existed prior to Nintendo's translating games to Dutch, Portuguese, and Russian to receive a new name in said translations, as opposed to keeping his English name.
