"Hate's great! Best villain!" — Watchdog's war cry.
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.
The Watchdogs are short, diminutive creatures who make up for lack of height through sheer numbers. They lack mouths (even though they have been demonstrated to speak, eat, and even kiss) or any other defining feature save for a giant single Cyclops like eyeball with red irises and black pupils.
They have purple skin, nails, and some seem to have red hair (if only in their armpits and on their chest). 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, with the exception of Commander Peepers, who has a different helmet.
Most Watchdogs do not like Wander and will always try to capture him. However, there are some that actually do like him (one even has a picture of him in his room in the episode The Gift 2: The Giftening).
The Watchdogs didn't seem to like Westley as they thought he was annoying, and always teased him. However, when he "captured" Wander and Sylvia on his own, they treated him with more respect and they were sad over his "death".

Background Information[]
They resemble Zigotons, the antagonists of the game "Patapon".
They could be considered the opposites of the Fist Fighters.
Despite having no visible mouths, they 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," "The Little Guy" and "The Brainstorm" (they have sandwiches for lunch).
They were even shown kissing at one point in "The Greatest".
Moose's name and physical appearance might be a reference to the character Moose Maddon, from the short story "The Moose And The Sparrow".
In Latin America, they are called "Furioguardias," which can translate to "Fury guards".
In Ukraine, they are called "Гострозорики", which translates to "Sharp sight," or more literally "Those who have a sharp vision".
They all wish that they had a second eye, as revealed in "The Birthday Boy".
The yellow variant
The Watchdogs and a variant of them with yellow irises appear in the game Disney XD Villains Unite!. They are encountered in the Wander Over Yonder level and, briefly, in the Randy Cunningham: 9th Grade Ninja level.
In "The Day", there is a scene in which they can be seen without clothes in a changing room (save for a white towel), revealing their skin color (pink) and shared hair color (red), as well as the fact that they seemingly have to shave their eyeballs (whether this is actually for hair or for another reason is unknown).
They seem to have no shame in showing their private areas, as they don't bother putting their towels back on after dropping them to attack Sylvia until she requests that they do (at first they responded by wrapping them on top of their heads, misunderstanding Sylvia's intentions). However, since they state Sylvia wanting them to wrap them around their waists "makes more sense," it is likely this was only intended as a gag.
So far, no female Watchdogs have made any sort of appearance, but Craig McCracken revealed on a tweet that there are indeed female Watchdogs and that they're currently residing on their home planet.
The Watchdog's catchphrase, "Hate's great, best villain," is a parody of Miller Light's slogan, "Tastes great, less filling".
In some episodes it is shown that they are very lightweight and it's easy for characters like Lord Hater and Sylvia to carry them.
