The Alien Bears are a species of ursoids currently ruled over by Emperor Xoon. They are pale, dark-greenish color and possess a pair of antennae that change color in correspondence to different situations: when alerted they turn red, though when calm they are instead a purple hue. They are hostile, technologically advanced beings whom are capable of utilizing mind control helmets to manipulate other sapient and possibly non-sapient races—this extends to the undead, as they have been witnessed controlling zombears. Outside of this mind control usage, they also wield ray guns.
When injured, Alien Bears have been witnessed leaking a green, gaseous substance.
