Greywhack is a character that appeared in "The Glorriors"; however, the episode was scrapped, and thus never aired.


Greywhack wears a black suit that looks like it is made completely of shadows. He has a utility belt and he has a strap across his chest that holds a sack of unknown content. He has a grey cape and a matching grey head that looks like it is a rock with an evil pumpkin face carved onto it.


As shown in "The Glorriors," Greywhack is shown to be an expert swordsman. He is also shown to have fire powers.


  • Greywacke is a type of sedimentary rock.
  • It was said by Adam Muto that Greywhack will most likely not appear in an episode of Adventure Time.[1]
