The "Schmartians" are minor villains in Wander over Yonder.
They're an evil race of green alien invaders who conquer all in their path and also the only independent villanious species in show. They are one of the most powerful villains in Yonder Galaxy and also a remarkabe parody of Martians of Mars Attacks!.
They are green humanoid aliens of average height with singular cycloptic eyes, butt-shaped heads and space suits with green dome helmets.
They use their fists or their ray guns in combat. Alone, they are about as tough as the Watchdogs or Fist Fighters, but together they can be quite overwhelming and will gang up on others. They travel in flying saucers which have laser weapons.
