King Antarctica

Antarctica is a xenomorph queen who the overarching villain of the aliens franchise. he appears as the main antagonist of the 2004 film Alien vs. Predator. he is 5,000 years old, much older than the First Acheron xenomorph queen. he is also bigger and stronger as well.

Background
after a millennia long war, The Antarctic Queen was captured by the Predators thousands of years ago and imprisoned inside a pyramid in Antarctica to lay eggs. Humans were sacrificed as hosts for the Xenomorphs and when they matured into adults they would be hunted by young Predators as a rite of passage. Since the Antarctic Queen was trapped in the pyramid for centuries, his children eventually outwitted the Predators and destroyed the human civilization that the Predators built with them. Unfortunately, the Queen was unsuccessful in freeing himself and was refrozen, unable to move until the next rite of passage.

Another Escape Attempt
Finally, in 2004, three Predators, Scar, Celtic, and Chopper, were sent to the pyramid to kill the Xenomorphs for another rite of passage. The humans (whom arrived earlier) activated the pyramid before the Predators could enter. The Queen was painfully reawakened and begun to lay his eggs.

The awakening was triggered by the humans retrieving the plasma casters, taking the sacred weapons of the Predators which were vital to the success of the hunt. The eggs hatched in the Sacrificial Chamber and implanted part of the human team with embryos, who would burst out and mature. The Xenomorphs quickly overran the pyramid, resulting in Celtic and Chopper being killed by Grid, a Xenomorph with leadership qualities who was still subordinate to the Queen.

Scar teamed up with Alexa Woods, the only survivor of the human team, and they turned the tides on the Xenomorphs. The Queen sensed his children getting killed and called for Grid and his other children to release him. They complied and crawled over his body, biting into his flesh, allowing the Queen’s acid blood to burn away the chains that held him captive for so long. The newly freed Queen rampaged through the pyramid.

The Queen managed to tunnel out of the pyramid right before it was destroyed by Scar and Lex. he became enraged when he witnessed his children killed in the blast. he saw the two responsible for their deaths and engaged them in battle. Scar made a stand against him, but was savagely beaten and rendered unconscious. The Queen raised his spear tail to end scar's life and to avenge his children, but Lex stabbed the Queen in the throat with a spear, causing him to stumble into a nearby house. he pulled the spear out of his throat and chased Lex, trapping Lex and trying to bite her, but Scar recovered and speared him through the head.

As the Queen thrashed and screeched in pain, Lex and Scar noticed a chain attached to him, which had not been burned off when the Xenomorphs freed the Queen. They grabbed the chain and attached it to a water tower just as the Queen ripped the spear out of his head. Lex and Scar tried to push the water tower off the cliff, but the Queen mortally wounded Scar with his tail. As he prepared to end Scar with a strike of his maw, Lex managed to push the water tower down the cliff, pulling the Queen away from Scar. he made one final attempt to kill Lex, snapping at her, but he missed and was dragged off the cliff and sank into the freezing ocean below. The Queen had been defeated, but at a price: Scar had died of the wounds inflicted on him, and he was implanted with a chestburster that would become the Gunnison Predalien. It is unknown whether or not the Queen drowned, as his final fate wasn't shown, nor can it be confirmed that Xenomorphs need to breathe.

Personality
His personality is more or less same with other Xenomorph Queens. he values and protects his brethren like any good mother would, and had no qualm in killing any non-xenomorph lifeforms whether as enemy or merely host for his facehugger children. Antarctic Queen has harbored a terrible grudge against his Yautja captors whom used her to breed more Xenomorphs only to be killed for their Rite of Passage. In spite of this, she is very persistent even whilst being restrained: Se has tried to called his brethren for help every time the Rite of Passage began, though only succeed in 2004 where he finally freed thanks to Grid's newfound knowledge about their kind's corrosive blood. Unfortunately, he did a fatal mistake where he ignored the final restrain that still intact on his body: The chain on the said restrain later used by Alexa and Scar whom tied it to a water tower which later dropped to the ocean, causing him to be pulled down to the ocean floor, where he apparently drowned.

Traits
Antarctic Queen had diverging traits compared to the younger, First Acheron Queen: Antarctic Queen has a far more pronounced line of spines along the top of his head crest. Antarctic Queen had greater height, at least nearly twice larger than First Acheron Queen. Antarctic Queen's appearance also had thinner, more "streamlined" body, sharper and spikier head crest, thinner, and more muscular neck. Antarctic Queen's hands also lack the distinct holes seen on the Acheron Queen as well.
