Fight4Rare is a charity program rooted in the fighting game community since 2022. Our mission is to raise awareness and fund accelerated research for rare diseases. At Evo, we’re supporting the Raiden Science Foundation (RSF) in its pursuit of a cure for UBA5 disorder. Inspired by the courageous journey of 6-year-old Raiden Pham, RSF is taking on UBA5 disorder as its first opponent.

After four years of research, a potential treatment is now within reach. But to move forward, we need to raise $3 million for manufacturing of the treatment. This is where we need the the support of the community. Every donation counts. Donate what you can, share Raiden’s story, and help us finish the fight.

Raiden’s fight is one story within a much larger rare disease crisis. More than 400 million people worldwide are living with rare diseases, and half of them are children. In a world of rapid medical innovation and life-changing research, progress often comes down to funding. Yet rare diseases remain critically underfunded, leaving too many families without clear answers, resources, or hope.

Thank you ModRetro for powering up our booth at Evo 2026 this year! ❤️

Raiden can't play. So we play for him.
