Weevil Underwood

Weevil Underwood, aka Insector Haga in the manga and Japanese version. He develops a rivaliry with Yugi Muto and Yami Yugi. He becomes very jealous of Yugi and Yami Yugi. He displays an adoration for insects and such has his Deck based on Insect-Type monsters. His best friend, and companion is Rex Raptor.

Appearance
Weevil's character design was overseen by Kazuki Takahashi. Weevil wears large round yellow glasses, which have an insect horn in the center to connect the lenses in season one; in the other 4 seasons, his glasses have a beetle in the middle, and holes on the legs. His Duelist Kingdom glasses magnify his eyes (or so it seems). His turquoise hair is arranged in a "Beatles' Haircut" fashion, and his eyes are blue. In the Duelist Kingdom arc, Weevil's outfit consists of a green jacket with a raised collar, a white shirt underneath, a red bow tie, brown trousers, and brown shoes. From Battle City onwards he wears a closed green jacket with a beetle pattern on the front, black shorts, and green-and-black sneakers with wing shoe laces. He carries a KaibaCorp Duel Disk on his left hand. In the Waking the Dragons arc he has a Chaos Duel Disk instead.

Weevil does not appear in the first series anime. However, his character and appearance are supposedly based off of the character Haiyama, who appeared in one episode of Season 0; they both wear yellow glasses, have colored hair, and are manipulative.

Personality
Weevil is mean,rude and go to way to get what he wants.

Background
It's unknown what Weevil was like during his childhoood.

Duelist Kingdom Saga
Weevil starts out in the series as the Regional Champion of Duel Monsters by defeating Rex Raptor in the final match of the Regional Championship. After his victory, he is invited personally by Maximillion Pegasus to travel to Duelist Kingdom to compete there. Upon meeting Yugi and his friends, he seemed a humble and respectful person, in contrast to the bold and arrogant Rex Raptor. However, he quickly revealed himself to be underhanded and sneaky (while Rex Raptor, ironically, shows decent sportsmanship and plays fairly). On the boat ride to the tournament, he confronts Yugi Muto and asks to see his set of Exodia. Once seeing them, Weevil takes them and throws them off the boat, leaving Joey to jump in to retrieve them. Laughing, Weevil returns to his cabin, confident that he has destroyed his major source of competition. Yugi defeats him in the first duel of the tournament, forcing Weevil to be the first duelist to leave the island along with those who had been defeated in their first round.

Battle City Saga
He is next seen in the Battle City arc, where he duels Joey, after "paying" a boy to plant a "Parasite Paracide" card into Joey's deck. Despite using this to his advantage, he loses and is forced to give Joey his rare card, "Insect Queen". As a result of losing, he is ejected from the Battle City tournament.

Battle City Finals Saga
He is later seen observing the semifinal match between Yugi and Kaiba in Domino City amongst other duelists.

Waking of the Dragon Saga
The story begins after the end of the Battle City tournament, when Atem wanted to recover his lost memories by using the Egyptian God Cards to activate the chamber of the Nameless Pharaoh King to inside the Memories World. Suddenly, a dark force freezes the Tablet of Lost Memories sealing him to prevent him inside making forbidden, unless this dark forces is destroyed. One night, a group of perpetrators break into the Kame Game Shop and steal the three God Cards from Yugi's grandfather Solomon Muto, who had been given the cards for safekeeping. Giving chase to the thieves, they eventually encounter Gurimo, a mysterious man in a cape. Gurimo is collecting souls for the group, and plans to collect the souls of duelists by defeating them in a duel. To this end, he uses "The Seal of Orichalcos" card, a Field Magic Card that could not be dispelled and prevented outside interference, with only the winner of the duel being able to escape and the loser having his soul taken by the Seal. Although Gurimo manages to unleash the power of "Obelisk the Tormentor" against its former owner, Yugi eventually wins the duel but ultimately fails to recover the God Cards.

The God Cards eventually arrive in the hands of Dartz, who sacrifices their power to awaken his Great Beast, The Great Leviathan.

The next night, as the world sees a giant eye in the sky, Yugi and the Pharaoh awaken in the depths of the Millennium Puzzle where they encounter "Kuriboh", urging them to follow a portal hidden inside the puzzle to the world of beasts. There, they are greeted by "Dark Magician Girl", who tells then the tale of The Great Leviathan, and urges them to pull a sword from an ice statue. They do so, and unlock the power of "The Eye of Timaeus", who proceeds to destroy the eye in the sky above the world of beasts. Similarly, Yugi would unleash the same power in the real world, forcing The Great Leviathan to retreat.

The other two Legendary Dragons would also be unleashed in a similar manner - "The Fang of Critias" was unlocked by Seto Kaiba in a duel, after kowtowing to a demand allegedly by Maximillion Pegasus to duel at his Duelist Kingdom as a publicity stunt. There, he discovers that one of the thieves, Amelda (Alister named for Aleister Crowley, who coined the unicursal hexagram that acts as the symbol of the Orichalcos, in the English version), had led him there, wanting retribution for what KaibaCorp had done against his family. Although "The Seal of Orichalcos" was indeed used, the battle was fought to a draw, allowing both Alister and Kaiba to escape unharmed.

The third Legendary Dragon, "The Claw of Hermos", would be unlocked by Joey Wheeler (Katsuya Jonouchi): when Yugi and his friends receive a video from Pegasus (as it turns out, shortly before he is defeated and his soul sealed), who implores Yugi and his friends to travel to America and retrieve a card holding the key to defeating their then-unknown threat. At Pegasus' Industrial Illusions HQ however, they are locked inside the building, where Mai Valentine (Mai Kujaku) emerges to battle Joey. During this duel, Yugi & friends discover that Mai had been wandering the Earth after their Battle City tournament: although she finished in the Top 8 she was always overshadowed by Joey, and continually traumatized by her loss to Marik Ishtar (in which she was physically and emotionally seriously scarred). Determined to become stronger at any cost and never wanting to lose another duel again, Mai eventually wound up with Dartz, eagerly accepting his offer of becoming stronger, not realizing that the power of the Orichalcos would be her undoing.

The change in Mai's behavior would, as it turns out, be partially due to Valon, the second of Doma's three Swordsmen, who had cared for Mai in her time of need, and wanted her to move on with her life by defeating Joey (effectively also doing his work for her). When Joey appears to have the upper hand in the Duel (thanks to "The Claw of Hermos"), Valon uses his Orichalcos stone to break the seal, rendering the match a no-contest and allowing both Mai and Joey's souls to survive.

Meanwhile Duke Devlin, accompanied by Weevil and Rex, would manage to break into the building and unlock the doors. Seto and Mokuba Kaiba would also appear, and all of them would help Yugi find the card that Pegasus claimed would help Yugi end the threat of Doma - yet, when they find it, it is blank.

The third swordsman, Rafael, would later challenge Yugi. Rafael claimed that Yugi and his friends are fighting for the wrong cause, and that Rafael was a noble hero out to save the world. He claimed that mankind was inherently evil, and that the Orichalcos exposed the darkness within the souls of mankind - thus the need for them to be sealed by "The Seal of Orichalcos".

However, as Yugi dueled, he finds himself easily outmatched by Rafael's Guardian Monsters, which he refused to allow to go to the card graveyard. After Rafael plays the Spell Card "Exchange", Yugi finds himself with "The Seal of Orichalcos" in his hand. Not wanting to lose yet not wanting to play the Seal, the two souls of Yugi would debate over whether to use the card. Blinded by the desire to win at any cost, Yami (in control of Yugi's body during the Duel) ignores Yugi's pleas and plays the Seal in order to power up his monsters. Using the ability of "Catapult Turtle", he sacrifices monster after monster to wear away at Rafael's Life Points, even sacrificing his trusted "Dark Magician" and "Dark Magician Girl" in the process. Yet, Rafael is able to survive and use the situation to his advantage by summoning "Guardian Eatos". Eatos would use the spirits of Yugi's own monsters to defeat Yugi.

As the Seal slowly circles around the fallen Pharaoh, however, Yugi realizes that two souls reside within one body, and allows the seal to take him instead, sacrificing himself so that the Pharaoh would survive. Meanwhile, Weevil and Rex, after seeing the power of the Orichalcos, seek to have the power for themselves.

The Pharaoh, despite the attempts of his friends to cheer him up, became distraught over the loss of his other self. Meanwhile, as the Pharaoh and company continue to travel, Weevil and Rex meet Dartz, who grants them the power of the Orichalcos. In return however, they are told to use their newfound power on the Pharaoh and Joey - a win-win scenario for Dartz in any event.

The two would manage to hijack the train the Pharaoh and company would be riding in - Weevil isolating Yami and Téa Gardner (Anzu Mazaki), while Rex finding Joey and Tristan Taylor (Hiroto Honda). Thus, the two Duelist Kingdom rematches were slated to begin, only with much more on the line. While Joey would have little trouble dispatching Rex with the help of his "Claw of Hermos", Timaeus would seemingly abandon the Pharaoh, forcing him to win the duel without it. He would ultimately prevail against Weevil with the help of "Breaker the Magical Warrior", which, along with its ability and "Berserker Soul", allowed it to attack Weevil repeatedly as long as the Pharaoh drew and discarded monsters - which he did ruthlessly. Téa would implore the Pharaoh to stop - long after he had beaten Weevil - just as Yami was about to discard "Dark Magician Girl". Just then, however, the moving train would head off a cliff, although they would survive, having been rescued by a mysterious person.

His virtually comatose body is found by Ironheart  when the train on which he had previously been dueling with Yugi derails and falls off a cliff, and he is transported to a hospital. When Dartz is defeated, Weevil's soul is released from imprisonment, and he wakes up in his hospital bed in the same room as Rex, who leaves with him.

Grand Championship Saga
Weevil and Rex's next plan was to enter the KaibaCorp Grand Championship, where they both impersonated the duelist, Fortune Salim. They were quickly defeated by Zigfried von Schroeder and sent back to Japan by KaibaCorp. (In the english version, their fate after the Duel is unknown.)

Dawn of the Duel Saga
Their last attempt at revenge was to steal Yugi's Egyptian God Cards from his house, where they mistakenly grabbed Yugi's bag containing all of his Millennium Items. Yugi tried to stop them, but couldn't catch up. Meanwhile while examining their prize, they were attacked by Dark Bakura, who stole the Millennium Ring back from them.

Ceremonial Battle Saga
In the final episode of the Japanese version,Weevil is seen Duelling Rex after yet another argument.

Yu-Gi-Oh! 5D's
In ''[http://yugioh.wikia.com/wiki/Yu-Gi-Oh!_5D%27s Yu-Gi-Oh! 5D's ]'', a parody of him named Insector Hakata is listed as one the players defeated by Hunter Pace.
