Genthru is best known as the main antagonist of the Greed Island arc, operating as a ruthless player who exploited the game's mechanics for profit. He initially ran a scam with a sizable crew, cornering the market on defensive spell cards while his team used offense spells to rob other players blind. It's a pretty straightforward con—control the defense, control who wins fights.
What made Genthru particularly dangerous wasn't just his strategy but his willingness to operate at scale. He had the numbers and the coordination to actually pull it off, which put him leagues ahead of your average griefer. Fans often note that his operation highlights how Greed Island rewards cunning exploitation just as much as genuine skill.
