- “Goblins are a mischievous and vengeful group of creatures led by a mustache-donning "Fragwa." While there are many types of goblins, the common green ones reside in Arcadia, aiding Bular, Strickler, and other villains in their missions. When not carrying out the grunt work, the Goblins are often found seeking their revenge for their fallen comrades. If you hear their cry, "Waka Chaka!" coming from down the street, it's sure to be followed by a horde of green.”
- ―The Art of Trollhunters
Goblins are small, ruthless, gremlin-like creatures that act as tricksters and street vandals, leaving a wake of destruction wherever they go.
The goblins usually work on their own terms, but occasionally follow the orders of the Gumm-Gumms and/or other evil creatures, like the Changelings while they rebuilt the Killahead Bridge and carried out assignments for them.
- “When the designs first landed on our writers' room table, we were immediately inspired to make the Goblins as fun and whacky as the looked. We kept coming back to them throughout our 52 episodes because they were so much fun to write and it became the running gag that most of our characters' introduction to the secret world of trolls (from Claire to Barbara) was through the Goblins.”
- ―Lila Scott, Staff Writer[src]
Goblins have usually have long arms and legs, feline-like ears, yellow and red eyes, large fangs, and sideburns.
Most of the common Goblins are usually blue or green.
However, the Blood Goblins (the ones that inhabit the Darklands) are white, despite their name, which Blinky once lampshaded to Toby when said race are first introduced in "Escape from the Darklands" when they tracked Jim's scent.
Goblins move in large groups and if one of them is killed, the others will not rest until they take revenge for the murderer and whoever gets in their way. Unfortunately, they have no concept of logical cause-and-effect, at least concerning the circumstances of their brethren's demise, and will swear vengeance against the most apparent culprit of it.
For instance, one such goblin was killed by being run over by a delivery truck; rather than take their vengeance out on the driver of the truck, the goblins attacked and destroyed the truck itself. This can lead to total innocents being targetted of such a vendetta, such as when NotEnrique killed a goblin in Enrique's room. Other goblins discovered the killed goblin's remains and found a picture of Claire Nuñez in the mess. Despite there being no evidence that Claire had anything to do with the incident, the Goblin immediately targetted her for deadly vengeance (shown in "Claire and Present Danger").
Being ruthless vandals, they usually work for the Gumm-Gumms and/or operate by themselves. Goblins often steal human babies and replace them with Changelings. Despite their aggressive nature, they are quite nurturing and gentle while caring for the Changeling Familiars in the Darklands.
The Blood Goblin species are much more ferocious, voracious, and bloodthirsty than the other Goblins, chasing any scent of former inhabitants of the Darklands (like Jim, Nomura, and Gnome Chompsky) until they find it.
Powers & Abilities
Goblins are able to crawl up walls, trees, etc. and can eat through an entire truck. They are also particularly attracted to the terror pheromone, which they can trace if a being is scared.
Unlike Trolls, they are not invulnerable as a lot of Goblins get smashed into green goo.
- According to A Brief Recapitulation of Troll Lore Volume 48, the goblins' battle cry, "Waka Chaka!", means "He shall be avenged!" in Goblinspeak.
