Blisk

The Blisk were once proud and mighty warriors that ruled an ocean paradise on Mars and frankly they were a little cocky about it and their enemies, the Furons went to war with them. The Furons nuclear weaponry reduced their world to desert and wiped them out completely, or so they thought. A damaged Blisk warship drifted towards Earth and crashed in Tunguska in 1908 and the warship was made into a permament base. Interestingly their language is very close to Russian which allowed them to blend in with their society and several of their members had taken on human forms to become political leaders such as Vladamire Lenin, Joseph Stalin, Nikita Khrushchev but not Trotsky, they went extinct when the Furon warrior Cryptosporidium destroyed their base, stopped their weapon and destroyed their hive and their leader on the moon, as well as the remaining survivors.

Technology
Their technology is completely organic, every form of machinery they created is alive; from ships to nuclear reactors. Most of their technologies require radioactive materials to work.

Racial Abilities
These crustaceans have the unique ability to absorb large amounts of radiation that goes into their defense shields, through a technicality they can assimilate humans thanks to a spore that can infect any host and genetically rebuild them into mutant human hybrids. They also posses the ability to project energy from their right claws. They share a single mind and don't have any form of individuality thus referring themselves as us and other plural words referring to a group.

Castes
Mutants: Also known as drones, the mutants serve as grunts to deal with any threat by slashing them or firing darts from their mouths. If they are killed in the current mutated form, the spores escape and infect any host that is near it. If shot with an anal probe, they are returned back to their human form.

Blisk Warriors: Large, scaly, and muscular creatures with massive right arms that fire a form of energy to deal with their enemies. They are basically the enforcers of the hive.

Crystal Blisk: A Blisk warrior with a red nexus crystal in its forehead and a stronger shield. There role is to protect nexus crystals.

Yeti: Yetis are albino variants of the Blisk and they are noticeably stronger than the warriors. Their role is unknown but they might have served as specialized Furon killers. It should be noted that they are solitary from other Blisk warriors, though they are occasionally seen with mutants.

Leader: Slightly larger than the warriors and the Yetis. They are the most powerful castes, often covered in armour that has a recharging unit which enables them to regenerate. They are equipped with cannons on their arms and back, and can cause a shockwave by punching the ground. Only one leader appears in Destroy All Humans! 2.
