The original Hero Kids flat plastic miniatures Kickstarter was a while ago now, but Arcknight have just kicked off their second campaign. I only mention this because the Hero Kids miniatures are available as an add-on for the new campaign!
For $30, you can get all 62 Hero Kids heroes as amazing full-colour plastic stand-ups!
