'''Professor Elvin Gadd''' is a recurring character from the ''[[Portal: Mario Brothers|Super Mario]]'' series who originally appeared as a supporting character in ''[[Luigi's Mansion]]''. He is known for his accomplishments in paranormal research and also for the various inventions that he has contributed to the ''Mario'' world.

=Background=

Professor E. Gadd was a paranormal researcher and inventor who spend decades catching ghosts, until his old age finally caught up to him. He first met [[Mario]] and [[Luigi]] in ''[[Luigi's Mansion]]'', where he helped Luigi to save Mario by lending him his old ghost-catching equipment, including the spectral vacuum [[Poltergust 3000]], a communications/map/storing device called the [[Game Boy Horror]], and use of his Ghost Portrificationizer, which could turn ghosts into portraits and vice-versa. In the 3DS remake, a future version of E. Gadd (apparently from the time frame of ''Dark Moon'', judging by the incomplete model of the Dark Moon in the background) also made contact and sent a gooey doppleganger of Luigi he had created named [[Gooigi]], so that his present self and Luigi could test it out for him. When Luigi finally saved Mario at the end of the game, E. Gadd took the money he had collected and bought Luigi a real mansion of his own.

The Mario Brothers had another encounter with him in ''[[Mario & Luigi: Superstar Saga]]''. E. Gadd left his ghost-catching behind him and decided to start up a chain of coffee shops known as [[Starbeans]], using his self-designed bean mixer for bold new flavors. Customers who mixed new flavors were given special accessories in return for their services, as well as previews of his new inventions, like the Poltergust 3001 and a Boo's Sheet. Within the ''Minion Quest'' mode of the game's remake, he also appeared in a cave that he fell into while pursuing ghosts and could be found by [[Bowser]]'s minions. He talked about his research and his work on a time travel device, in reference to ''Partners in Time''. E. Gadd also appeared in ''[[Mario Party 6]]'', as the host of a few events on his own personal board, E. Gadd's Garage, and in ''[[Mario Party Advance]]'', having invented various collectibles called Gaddgets.

==Partners in Time==

In ''[[Mario & Luigi: Partners in Time]]'', E. Gadd built a time machine powered by the Cobalt Star. [[Peach]] and two of her attendants used it to travel back in time, unfortunately right into a [[Shroob]] invasion. While the Mario Bros. went to the past to collect the Cobalt Star shards, E. Gadd remained at [[Peach's Castle]], where he studied a captured Shrooboid. He also sent [[Stuffwell]] after the Mario Bros., a robotic suitcase designed to advise them and store their belongings.

The Mario Bros. and their baby forms later ran into E. Gadd's younger past self at his lab on the side of Thwomp Volcano, where he studied [[Thwomp|Thwomps]] long ago. When the volcano erupted, his lab took severe damage, but watching Baby Mario spit on the fire to put it out gave his future self the inspiration for the Hydrogush 4000, a FLUDD-shaped device strong enough to douse even volcanic eruptions. The young E. Gadd then moved to a new lab on the edge of the Boo Woods to take up paranormal research. The present E. Gadd, meanwhile, used his Hydrogush to spread a liquid with the chemical make-up of baby tears throughout the past Mushroom Kingdom and rid it of the Shroobs for good. He also fixed his time machine and, for lack of the Cobalt Star, altered it to run on the energy generated from Time Holes, thus making it possible for the Baby Mario Bros., Peach, and [[Toadsworth]] to return to their time.

==Further Adventures with Luigi==

E. Gadd later traveled to [[Evershade Valley]], where an object called the [[Dark Moon]] made all of the local ghosts friendly. Fascinated by this, Gadd decided to conduct research in the area and built his new laboratory in a building known as the Gloomy Manor. The various friendly ghosts acted as his assistants, and he also had several [[Toad (species)|Toad]] assistants as well. Things went well until the events of ''[[Luigi's Mansion: Dark Moon]]'', when King Boo shattered the Dark Moon. This caused the ghosts to suddenly turn hostile. E. Gadd was forced to flee from his lab and took shelter in a nearby bunker. He quickly contacted Luigi and used his new invention, the [[Pixelator]], to teleport Luigi to his bunker, particle by particle. E. Gadd sent him to the Gloomy Manor to retrieve the newest model of the Poltergust, the Poltergust 5000, and he then guided him in a series of missions that took Luigi across the various areas of Evershade Valley.

Luigi ended up gaining a shard of the Dark Moon in each area, which was corrupted by evil energy. Gadd had a machine that was able to clean each Dark Moon piece, which revealed more areas of Evershade Valley. Eventually, Luigi was sent to the Treacherous Mansion to search for the final piece of the Dark Moon. It was then that they discovered King Boo's hand in the scheme and that he had captured Mario again. With further guidance from Gadd, Luigi was able to seek out King Boo and defeated him again. Afterwards, they reunited the Dark Moon, and the ghosts' friendly natures were restored. They were then freed from E. Gadd's ghost container, and Gadd joined everyone else in the celebrations that ensued.

He also appeared in ''[[Luigi's Mansion Arcade]]'', which followed a heavily truncated version of the story of ''Dark Moon''.

==Impact==

E. Gadd has also had an indirect impact in other games, where his inventions appear without he himself playing a role. He is responsible for [[FLUDD]] and the magic paintbrush in ''[[Super Mario Sunshine]]'', the Gaddlight in ''[[Mario Party 4]]'', a series of battle machine parts in ''[[Mario Party 5]]'', Luigi's Poltergust 4000 kart in ''[[Mario Kart DS]]'', and the Surprise Wands and Coin Vacuums in ''[[Mario Party 7]]''. In addition to Starbeans, E. Gadd seems to be the owner or inspiration for E. Gadd Scientifics, Inc., a company that produces his products on a much more universal scale.

An E. Gadd Scientifics lab is seen in the [[Diamond City]] level of ''[[Mario Kart Arcade GP]]'', along with a golden statue of E. Gadd.

=Other Appearances=

==Video Games==

*In the ''[[Portal: Super Smash Bros.|Super Smash Bros.]]'' series, E. Gadd has been represented by a trophy in ''[[Super Smash Bros. for Nintendo 3DS/Wii U|Super Smash Bros. for Nintendo 3DS]]'' and as an Advanced-rank Support [[Spirit]] (with the effect of raising energy shot attack and resistance) in ''[[Super Smash Bros. Ultimate]]''.

=Trivia=

*His English name is a play on "egad", which is simply an exclamation one makes when surprised or frightened. It was most likely chosen due to being an exclamation one would make upon seeing a ghost.
* E. Gadd's name in the Japanese version of ''Luigi's Mansion'' is Professor Oyama, in homage to Nintendo designer [[Yoshiyuki Oyama]]. By listening closely to his gibberish, he can be heard saying "Oyama" a few times.
* When E. Gadd first started into the ghost-catching business, he was just as terrified of ghosts as Luigi is.
*His appearance is also available as a [[Mystery Mushroom]] costume in ''[[Super Mario Maker]]''.
