Weevil Underwood

Weevil Underwood develops into a rival of Yuki Muto. He displays an adoration for insects, and as such his Deck is based on Insect-Type monsters until it was destroyed by Dr. Eggman. He was killed in the hands of Momoshiki Palpatine.

Pre-Mega Man ZX Shippuden
Weevil starts out as the Duel Monsters Representative of Eastern Japan, and then National Champion of Duel Monsters by defeating Rex Raptor in the final match of the National Championship. After his victory, he is invited personally by Maximillion Pegasus to travel to Duelist Kingdom to compete there.

Upon meeting, 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 and asks to see his set of Exodia. Upon seeing them, Weevil takes them but Dr. Eggman destroyed Weevil's deck of insect card by tossing to the sea. Weevil then gives Yuki Muto back the Exodia before he was killed by Momoshiki Palpatine.
