According to Marvel, the show is an 'unscripted series that shares the positive impact several young, real-life heroes are making in their own communities across the country'.
Describing the young people in the show as 'extraordinary and inspiring', the production company said it was celebrating them as the 'true superheroes they are immortalized in their very own comic book, as they join Marvel's Hero Project'.
'Such an honor'
Speaking exclusively to Plant Based News, Butler revealed how excited she is to be involved in the project.
"It's such an honor to have Marvel share my vegan, animal, and environmental advocacy on Disney's new streaming channel," she said.
"I still can't believe I'm part of the Marvel Universe and I can't wait for the world to find out why it's so important to have compassion for all species!"
Despite being just 12, Butler is no stranger to advocating on a world stage. In 2017, she recorded a highly-viewed TEDxCSULB talk titled A 10-year old's vision for healing the planet.
Earlier this year, she traveled to Rome in a bid to speak to Pope Francis and encourage him to try a vegan diet for Lent, as part of the Million Dollar Vegan campaign.
Discussing her motivation, she said: "Animal farming is one of the leading causes of global warming, and by choosing to eat a plant-based diet we could reduce the harm we cause to the planet, to animals, and to people."
Marvel Hero Project will stream on Disney+ from November 12.
