Heroes joined forces at the Quincy Mall on Saturday.
Volunteers with the Hannibal Heroes Unlimited United for a Cause dressed as Hawk Girl, Power Rangers, Blade, Wolverine and Deadpool.
While they said Saturday was about raising awareness for their group, they said they do so much more for the community.
"We've helped with the American Foundation for Suicide Prevention," member Julianna Baker said. "We helped out with the suicide walk last October and we raised funds for them and helped set up."
Members said they have also helped with the Loaves and Fishes program in Hannibal and helped collect toys for Toys for Tots.
They said they hope one day the group can become a non-profit organization.
