Mahziis, also known as Malleo's Army, are the elite army led by Malleo, though Toon Malleo is usually Malleo's form for leading them. Their goal is to wipe out any Non-Fakegee/Weegee/Malleo off the face of the United 'Gees Galaxy. Weegee is also a commander, though he usually spends time in his own army.
