Gnaar

The Gnaars are a race of bipedal mammals originating from the planet Sirius, known for their constant hunger and stupidity.

Overview
The origins of the Gnaar race are largely unknown. They are believed to be the result of genetic experimentation, mutation from ingesting toxic waste, or perhaps they simply stowed-away on ships entering Sky City and took up residence in the sewers. Regardless, the Gnaars were discovered by Mental after he seized control of Sky City and conscripted into his horde.

In appearance, a Gnaar is a bipedal creature whose torso is entirely dominated by their massive fang-filled mouth. Above this mouth is a single eye capable of night-vision. Notably, female Gnaars are identified by their green skin, hulking size and tendency to walk on their knuckles in a similar manner to gorillas. In contrast, male Gnaars are smaller, purple-skinned and mobilise exclusively on their legs. However, some Gnaars have demonstrated the ability to turn partially invisible or even levitate, retracting their limbs to perform the latter. Despite their size and strength, Gnaar are surprisingly vulnerable to small-arms fire, and will die instantly from any damage inflicted on their eye. As such, Mental employs Gnaars exclusively as cannon fodder.

Unlike most species inducted into Mental's Horde, Gnaars do not make use of weaponry, or any technology for that matter, instead relying on brute strength for attack. Due to their stupidity, Gnaars lack the mental capacity to think beyond the consumption of anything they can find, including garbage and corpses. As a result, Gnaars have reportedly horrendous breath. Interestingly, despite their constant hunger, Mental has somehow trained the Gnaars not to attack and eat their allies.

Despite their lack of intelligence and brutish behaviour, Gnaars are in fact sapient. Although they rarely show anything beyond instinctive behaviour, a select few Gnaars have demonstrated some capacity to be more than primitive beasts. For example, a Gnaar known as George B. Gnaar was employed as a news presenter, while Johnny Lee Gnaar worked as a street performer.
