The Beginning

The Hork-Bajir /ˌhɔːrk.bəˈdʒɪər/[1] are a former peaceful alien race, who became enslaved by the Yeerks and used by them as shock troops.



The Hork-Bajir are bipedal, have strong reptilian bodies with dark green-black leathery skin, and at least two hearts. They have snake-like necks with a sharp beak at the end of their heads, tyrannosaurus-like feet, three claw-tipped fingers and a thumb on each hand, and measure to a height of seven feet in adulthood. Their most notable feature is that they have huge, long blades all over their bodies: their elbows, wrists, feet, legs, head, and tail. Male and female Hork-Bajir are told apart by the number of blades on their heads; males have three blades while females have two. According to Jara Hamee, there is another difference, but claims that it's only for Hork-Bajir to know.[2]

Although they look fierce, the Hork-Bajir are a race of pacifists. They never even understood the concept of violence or fighting until the Yeerks showed up. Their blades are used for stripping bark off the huge 100 to 1,300-foot trees on their homeworld. In fact, there was a lot they didn't understand, since their mental capabilities don't really measure up to those of most other races. Their intelligence is equivalent to that of a human toddler. Although, some suspect that they may simply be intelligent in different ways that they don't show. They can't see well in the dark, but they do have an excellent sense of hearing[3] and smell.[4] Their blood appears in shades of deep red and deeper blue-green. They also can stand a lot of pain and heal quickly.


Before their enslavement by the Yeerks, the Hork-Bajir were regarded as a backward but peaceful race that possessed little evidence of art, language or even music. They were divided into separate tribal groups, that spread across the valleys of their world.  Centered around each of these tribes was the Tribe Tree, the main tree used by the Hork-Bajir as their center of social organization.  Despite their primitive state, the Hork-Bajir had a rich oral culture centered around their two creator deities Father Deep and Mother Sky.  In addition, they were technologically adept at using hollowed-out trees, known as the Speaking Trees, as a means of primitive long-distance communication.


The Arn, a now extinct race and the original inhabitants of the Hork-Bajir homeworld, created the Hork-Bajir to look after the huge trees of their homeworld by stripping and eating the bark off of them. When the Arn created the Hork-Bajir, there was a gene they could not weed out, the gene of intelligence. Every thousand years or so, one of the Hork-Bajir is born a "seer". The seers are much more intelligent than their brothers and sisters and in times of trouble, the other Hork-Bajir may look to them to lead.

Tila Fashat:

The Hork-Bajir homeworld was the first world the Yeerks reached out to for conquest. When they first saw them, the Yeerks thought the Hork-Bajir were huge warriors, not peaceful, gentle bark eaters. So they enslaved them to become fierce soldiers. The remaining free Hork-Bajir were destroyed by the Quantum Virus, which War-Prince Alloran-Semitur-Corrass had programmed to kill all Hork-Bajir--Controllers as well as the free Hork-Bajir still alive on the planet-- to prevent them from becoming enslaved. In The Hork-Bajir Chronicles, a young Hork-Bajir seer named Dak Hamee befriended an Andalite named Aldrea-Iskillion-Falan during the Hork-Bajir war. Aldrea morphed and became a Hork-Bajir nothlit, and the two later married. They had a son Aldrea named Seerow (after her father). Her great-granddaughter, Toby Hamee is also a seer.

Tobias and the Free Hork-Bajir:

The Hork-Bajir are used throughout the series against the Animorphs as Yeerk foot soldiers. In Animorphs 13: The Change, with the interference of the Ellimist, Tobias and the other Animorphs help a Hork-Bajir couple named Jara Hamee and Ket Halpak escape the Yeerk Pool and establish a colony for free Hork-Bajir in a hidden valley deep in the forest that was created by the Ellimist. Throughout the series, Jara and Ket continue to help other Hork-Bajir to freedom. By the end of the series, they became a free species, establishing a new home, protected by the American government, on Earth.

Trivia Edit

  • Ax once claimed that Hork-Bajir frequently fought each other due to a biological clock[5]. Since this was mentioned long before any free Hork-Bajir appeared in the story and seems at odds with their peaceful nature, it is likely an inconsistency or perhaps Ax made a mistake as he didn't seem to know a lot about the Hork-Bajir as much as Elfangor.
