He started giving workshops in 2014 about topics like inclusion, identity, disability, and intersectionality for
Extend-A-Family Waterloo Region, and for other places, including the YMCA, public libraries, schools, and
Family & Children's Services of the Waterloo Region, helping people reshape perspectives, while blending art, adventure, and advocacy for a more inclusive future. He was on panels for
Heroes Manufactured and
Green Light Arts' This is the Point. The latter's panel discussed navigating relationships when you have a disability. In 2024, he served on the
Region of Waterloo's Upstream Fund committee, helping select applications for funding.
That same drive for representation carries into his cosplay and modelling work. André has modelled for photoshoots both related to and separate from the Comic-Con community, in which he remains active, with his main cosplays being the Wally West version of The Flash and Miles Morales' Spider-Man. Campbell appeared as The Flash in 2019 for
Easter Seals Canada,
Cosplay for a Cause, for
Holland Bloorview Kids Rehabilitation Hospitals' Capes for Kids fundraiser in 2023, alongside the
Toronto Raptors 905 (the feeder team to the
Toronto Raptors), and during Halloween 2025, he appeared as Miles Morales, along with a few friends and fellow cosplayers, in Hamilton, Ontario, for
Treat Accessibly – a national, family-founded movement helping Canadians make Halloween accessible for children with any disability at every home.
These modelling experiences, along with creating content with his best friend, writing partner, fellow cosplayer, and co-host Brandon as the Scarlet Nerds, led to Warner Bros. inviting him to join a social media campaign cosplaying The Flash for
DC FanDome in 2020. The company captioned one of their videos with, "the Speed Force is for everyone around the world. Including cats." This statement resonated deeply with Campbell, reflecting the inclusive themes of the comics he loved as a kid.
His work breaks barriers, challenges the status quo, and strives to ensure everyone finds a place – or that new places are built for those who need them.
