Dark Matter

Dark Matter are evil residents of space who appear in Super Mario Galaxy 3: Meteor Shower. They are evil purple and black shapes who want nothing more to help Bowser and live on the planets the P.O.O.P. make them.

Placeholder in the gam
In the game, they cling onto normal rivals and turn them into Dark Matter creatures. Some even serve as bosses, such as Dark Matter Lubba, Dark Matter Peach, even Giga Dark Matter Bowser. The shapes they appear in are circles, squares, triangles, even octagons. They're was also a Dark Matter Rosalina, but this boss was removed for unknown reasons.

Relationships
They relate good with Bowser, Bowser Jr., his kids, and the P.O.O.P.. They relate badly with Mario, Semi Star, Rosalina, and pretty much everything that's trying to stop them. However, they have a strict rivalry with the Yoshi army.
