The Kleers are a species that appear throughout the Serious Sam franchise.

Overview[edit | edit source]

A Kleer skeleton, the undead remains of a Kleer.

The Kleers were once a race of sapient creatures from the planet Kleer, of Alpha Canis Majoris. This once peaceful planet was rich in biodiversity and life, such as plants, forests and water. The most notable species on the planet were the Kleers; a species with a very strong cultural background.

After Mental found their planet, he dropped approximately ten billion gallons of napalm onto the planet, effectively wiping the planet clean of life. After the Kleers became extinct, they were resurrected as skeletons, with their bones held together by magical chains. These magical links are quite frail however, thus the skeleton of a Kleer can be shattered with a powerful blow.

Now serving in Mental's army, Kleers are some of his most common units, where he will sometimes deploy hundreds of even a thousand of them at a time, suggesting that the planet was home to a large population of the species. Their main attacks are to conjure twin chainballs at the target from a distance, or to leap at their prey with their large scythe-like claws. At closer range, they will slash the target with them.

Appearance[edit | edit source]

As Kleers only exist as skeletons, it is unknown what they looked like before they met their extinction. It is also not known if they had mammal or reptile-like traits, though due to their skeleton's gait, it can be assumed they had mammalian origins. In their skeletal form, Kleers are somewhat similar to that of a horse, but only in stature, as they have unique physical properties. They have large, sharp horns on their heads, a long tail, and hooves on their two hind legs. Their skeletons are held together with magic.

Their appearance has also changed throughout the series. In Serious Sam: The First Encounter and Serious Sam: The Second Encounter, Kleer Skeletons are a light brown color. This appearance remains true in the HD remakes, with the exception of the eyes, which glow yellow. In Serious Sam 2, their appearance is the same with regards to their color and shape, but they have more horned protrusions from the shoulders and skull, along with glowing yellow eyes.

In Serious Sam 3: BFE, Serious Sam VR: The Last Hope and Serious Sam 3 VR: BFE, Kleer Skeletons look very different than the previous games; they have larger skulls with an additional third horn, while the other horns are more rounded. The color of their skeleton is now much darker, making it looked scorched. They also have reddish glowing eyes.
