MettaDogs

The MettaDogs are a race that live in the RockVerse. They are the ones who created the GenoKnife and the MettaDogGlove, which is needed to hold the knife. They currently have 120,000 MettaDogs living there.
They first gave the MettaDogGlove to Destroyer of Flex Tape, who copied the GenoKnife and made several molds from it, to create the GenoKnife factory, which was destroyed when it was replaced with the Dust Chara factory.
Lunarae got a GenoKnife from a MettaDog glove. (apparently she is too nice)
