ZUthon: Zelda for Eternity is a 100 hour charity livestream where the team at Zelda Universe plays a variety of games in The Legend of Zelda franchise with unique twists whilst raising money for charity. Originally devised as a way to celebrate the launch weekend of The Legend of Zelda: Breath of the Wild in 2017, ZUthon quickly evolved into a multi-day event with collaboration across multiple teams at Zelda Universe from all over the world.

As of August 18th, 2023, ZUThon: Zelda for Eternity events have raised over $47,000 for various charity organizations, including St. Jude Children’s Research Hospital, Direct Relief, and TheAbleGamers.
