The Watchdogs serve as Lord Hater's minions and troops responsible for conquering planets and capturing opponents of Hater's in the name of their aforementioned evil master. Their warcry is "Hate's great, best villain!"
The Watchdogs are short, diminutive creatures who make up for lack of height through sheer numbers. They lack mouths (Even though they can speak fine) or any other defining feature save for a giant single Cyclops like eyeball with obvious red irises and black pupils on each. Like their overlord, Lord Hater, the Watchdogs have a single lightning bolt coming out of the tops of their helmets, although they have just one while Hater has two. They all dress identically in black and red uniforms.
They also can eat as shown in The Picnic (one Watchdog tried one of Wander's sandwiches), The Greatest (two of them were eating ice cream), The Prisoner and The Little Guy, but they seem to just put it up to their face so it is unknown if they are really tasting it, or if they even get hungry.
