Professor E. Gadd

Professor Elvin Gadd, better known simply as E. Gadd (Karl Tastroff, better known simply as K. Tastroff in French), is a supporting character in the franchise, most notably serving as the overarching protagonist of the series.
He is an eccentric and brilliant scientist specializing in ghost-hunting and inventing. Various inventions found throughout the Mario series can all be traced back to him. He is considered the resident genius of the Mushroom Kingdom. He is Luigi’s mentor.
He is voiced by Japanese composer Kazumi Totaka, who also voiced Yoshi and Birdo. 
==Appearance==
Professor E. Gadd is a small man with, for only hair, a small straight tuft in the middle of the skull. He has a tooth and always wears glasses, a blouse and brown shoes. His glasses have a spiral pattern.
==Biography ==
===Luigi's Mansion ===
He appears for the first time in the game when Luigi enters the Parlor on the second floor. As the trembling Luigi wanders in the room, he encounters an orange ghost that suddenly scares him. When it looks like the ghost is going to attack Luigi, Professor E. Gadd appears, sucking the orange ghost with the Poltergust 3000. Despite his efforts, he fails to suck in the orange ghost, but at least manages to drive it away. Afterwards, Professor E. Gadd presents himself to Luigi, explaining that the entire mansion is haunted. He says he is surprised at Luigi's courage to enter the mansion alone and asks him what brings him to the creepy manor. Then Luigi and E. Gadd leave to the latter's laboratory after some ghosts materialize and try to catch them. E. Gadd has heard who Luigi is, how his life went and the backstory of the mansion. Luigi explains that he is looking Mario, who has been missing in the mansion for a while. Agreeing to help Luigi find his brother, Professor E. Gadd hands the Poltergust 3000 to Luigi and starts to train him in the training room. After the training, Luigi then goes to the mansion with the vacuum cleaner and a flashlight. In addition to the Poltergust 3000, E. Gadd also provides him the GameBoy Horror, through which he receives tips and information from the professor. E. Gadd guides Luigi throughout his quest in the haunted mansion. Once Luigi beats the Boss Ghost of an area, Professor E. Gadd summons him back to the Lab so they may turn the ghosts back into paintings. Eventually Luigi defeats King Boo and rescues Mario. And E. Gadd, in gratitude to Luigi for returning his paintings, uses the treasure Luigi found to get him a new home. 
===Luigi's Mansion: Dark Moon ===
In Luigi's Mansion 2, E. Gadd reappears during the game's cinematic opening. Here, he works in the laboratory of Gloomy Manor with the help of Greenies, due to now living in a location where ghosts are actually friendly. At the same time, King Boo breaks the Dark Moon and disperses the fragments. The ghosts of Evershade Valley then become angry and ransack the professor's study room while driving him out of the place. The professor, after making an escape, reaches his bunker and wakes up Luigi by appearing on the screen of his television. He teleports him to his headquarters using the pager. It is here that the professor continues his research while giving missions to Luigi.
===Luigi's Mansion 3===
Professor E. Gadd returns again in Luigi's Mansion 3. For the first time in the series, E. Gadd was imprisoned in a painting by King Boo, and Luigi must find him so that he can help him find Mario, as well as Peach and some Toads who have disappeared with him this time. Just like in the previous installments, E. Gadd provides Luigi with a Poltergust, and gives him advice (as well as further assistance/upgrades) from his portable laboratory, which is located in the parking garage on the basement floor of the Last Resort after he sets it up there. Whenever a Toad is rescued, E. Gadd has Luigi bring them to the lab where they will be safe. In the end after King Boo and Hellen Gravely are defeated, the hotel collapses and the enemy ghosts stop acting hostile thanks to King Boo’s gem disappearing. E. Gadd leads the group in rebuilding the hotel, this time into his likeness. He and Gooigi and the reformed ghosts remain in the new hotel while waving goodbye to their friends.
===Super Mario Sunshine===
Although Professor E. Gadd did not physical appear, he is referenced several times throughout the game. When Mario initially finds F.L.U.D.D. at the Delfino Airstrip of Isle Delfino, it says, "Thank you for purchasing this item from Gadd Science, Inc." . Later, Bowser Jr. says he acquired his Magic Paintbrush from "a strange old man in a white coat", referring to Professor E. Gadd. Bowser Jr. uses the paintbrush to pollute the entire Isle Delfino by painting it with goop, causing the Shine Sprites to leave the Shine Gate, and frames it on Mario by disguising himself as "Shadow Mario", and kidnaps Princess Peach under the mistaken belief that she's his "mama". 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. Bowser Jr. claims E. Gadd gave the brush to him of his own free will and that he did not know the professor's name when he received the brush, but it is unknown whether this is true or not. 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: Superstar Saga===
E. Gadd appears as the owner of Starbeans Cafe. When the brothers give beans to make a new drink, he appears to tastetest it (or has someone else taste it for him.) After he is finished, he would give the brothers a new special item that would help them with unique abilities, money or exp. If all drinks are made, he puts his portrait in the cafe, to which his employee says "It kind of stinks."
===Mario & Luigi: Partners in Time===
He returns in the game where he shows the heroes his newest invention: a time machine. After Princess Peach uses the time machine, a Junior Shrooboid appears as the time machine reappears. Once the heroes defeat it, he places it in a tube of fluid to study it. He gives the heroes Stuffwell (a senteint suitcase) to help the heroes on their journey. 
His youner self appears in Thwomp Volcano studying Thwomps. Once the valcono erupts, one Thwomp tries to explode and the heroes stop it, thus giving his future self the idea to make the Hydrogush 4000, a massive water pump, allowing the heroes to to douse the mountain on Thwomp Volcano. 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. 
==Personality==
Professor E. Gadd is eccentric, friendly and intelligent as he is one of the world's greatest scientists and inventors. Because of his accent and way of speaking, E. Gadd often sounds like he's speaking in gibberish. In the sequels to Luigi's Mansion, while he retains his generally kind and helpful personality, he also shows a bit of a mischievous sense of humor, such as laughing at Luigi's expense when he gets frightened and playing small jokes on him, like trapping Luigi in a cage when he first introduces and explains how Gooigi works to him in Luigi's Mansion 3, initially pretending he has caught him in a trap, only to assure he was kidding and doing so to help him learn how to effectively use his new companion to get himself out.
