I guess you just weren't listening when Pegasus said that this tournament would have exciting new surprises in store for us! Maybe if you were smart enough to steal the tournament's secret new rules like I did, you'd be getting a field power bonus instead of me!
~ Insector Haga, revealing that he cheated in order to learn Duelist Kingdom's new rules about field power bonuses.

Insector Haga (or Weevil Underwood in the 4Kids dub) is a minor recurring antagonist in Yu-Gi-Oh!. He is a duelist whose deck is based on Insect monsters, as well as an unrepentant cheater ready for the worst in order to stand on the top. In fact he never cheats during duels though beforehand such as throwing his opponent's Exodia cards, sneaking cards into his opponents decks and likely stacking his deck etc.

He was voiced by Jimmy Zoppi in the 4Kids dub.


Weevil’s personality is best described as: Deceptive, scheming, greedy, sly, cunning, highly creepy, witty, callous, intelligent, entirely arrogant, dishonest, determined, sneaky, somewhat pompous, tricky, calculating, unscrupulous and repulsive.

When Yugi and Joey first meet Weevil he seems humble and good-natured in contrast to his friend Rex Raptor. However in truth Weevil relies on underhanded tactics such as how he managed to pull Yugi into the forest so his insect monsters could get the field power bonus, in the hopes Yugi wouldn’t have the same advantage.

A key indication that he is an antagonist is the fact that part of his name has the word evil in it. Although he is usually far from sinister or dastardly, he is smug and aggressive.

The Anime

Haga was the regional champ, defeating Dinosaur Ryuzaki in the finals. Although it’s later revealed that he won his duels because of cheating.

Duelist Kingdom

He entered Pegasus J. Crawford's Duelist Kingdom tournament. In his first interaction with Yugi Muto, he acted polite and friendly in order to gain his trust and was given his Exodia cards.

He then immediately threw the cards over the edge of the boat into the sea to prevent him from using them. (This pretense of politeness is much more believable in the original Japanese version than in the dub, when he sounds downright sarcastic and untrustworthy). Joey Wheeler was only able to recover two of them. Yugi immediately decided to duel Haga first, risking his one Star Chip as well as his deck against Haga's two Star Chips. (In the manga, Yugi bets his life.) Yugi defeated Haga when he destroyed his Great Moth with his Demon's Summon, and the Japan regional champion was eliminated from the tournament and kicked off the island. Joey took his dueling glove.

Battle City

Haga entered Kaiba's Battle City tournament in Season 2, with a new card, Insect Queen, more rare and powerful than his Great Moth. He promised a kid a rare card if he put a parasite card in Jonouchi's deck, but double-crossed him and sprayed him with arachno slime. Jonouchi dueled him, believing that he had stolen the kid's cards, and was unaware that the kid was working for him until he discovered the parasite card, which turned all his monsters into insects and prevented them from attacking (due to his Insect-Repellent Barrier), but his metal warrior was unaffected, and Jonouchi defeated Haga, taking his two Locator Cards and kicking him out of the tournament.

Waking the Dragons

In Season 4, Waking the Dragons, Haga and Ryuzaki attempted to steal Yugi and Jonouchi's rare cards, but were challenged to a duel by Gurimo, who beat them and took their souls. They were released after Yugi defeated Gurimo. Haga and Ryuzaki snuck aboard during Yugi's trip over to Pegasus' castle in the hopes of finding rare cards and tried to get an Orichalcos card from Rafael, becoming two of Dartz's henchmen after hitchhiking aboard Rafael's helicopter. Haga dueled Yami Yugi on top of a train, where he crossed the Moral Event Horizon by tearing up a card and claiming that Yugi's soul had been trapped inside it (thereby killing him), then sadistically revealed that he had been joking; the card was a merely a common Insect monster card. Enraged, Yami eventually defeated him by overkill. His soul was taken by the Orichalcos, and was released when Dartz and the Orichalcos God were defeated.

Grand Championship

In the first half of Season 5, Grand Championship, Haga and Ryuzaki entered Kaiba's tournament as one duelist, and dueled Zigfried von Schroeder, who easily defeated them with his Valkyries.

Dawn of the Duel

In the second half of Season 5, Dawn of the Duel, Haga and Ryuzaki stole Yugi's Millennium Items and Egyptian God Cards (only going after the latter), but ran into Dark Bakura, who knocked them out (sent them to the Shadow Realm in the 4Kids version) and returned the cards and items to Yugi. They suffered a lot of the consequences of Zorc ravaging the past, but survived it all.
