Weevil can be unlocked by winning the Weekend Tournament, a certain number of times. The player can Duel him at the card shop on Mondays, the Coliseum on Tuesdays, the K.C. Tower on Wednesdays and Saturdays, the hometown on Thursdays and near the shopping district on Fridays and Sundays. He also faces the player in the K.C. Tower Tournament and is a potential round two opponent in the Sugoroku Tournament. When the text "Talk to him if you have Insects in your Deck!" appears on the screen, the player can challenge Weevil to a Special Match, if the only monsters in their Deck are Insect-Type. If the player wins, they get cards from the Insector Collection Pack.
