Instead of 

heroes = graphene.Heroes(HeroesType)

You need 

heroes = graphene.List(HeroesType)

Heroes is your model, and does not belong to Graphene.

Then you need to rename resolve_links as resolve_heroes

P.S. Good practice is to name your django modules in the singular, i.e. Hero, not Heroes. You can set the verbose name for the plural in Meta if it's not just adding an 's'.
