Name: Nike Kallista
Species: Olympian
Gender: Female
Age: 23

Bio: Nike is from an ancient Greece-like world. From a young age she took interest in training like the boys in her hometown, eventually surpassing even them in physical prowess and earning the reputation of the strongest woman in the domain. Named after the goddess of victory, she is undefeated in fighting competitions, though this is the first time she gets involved in a tournament of this caliber.

Fighting Style: Greco-Roman wrestling

ENTRANCE:
Nike entered the fighting arena clad in her toga, a crown of golden leaves ornamenting her tied-up hair. As she stood in front of the seats of select VIP group that would witness the fight live, she took off the pin that held together her garments, and flexing her arms up, let it all slide down to her feet, revealing her impressive muscular physique. She would fight nude, like the athletes in the ancient Olympic games.
Through the shadows of the dark room she spotted the glimmer of her opponent's skintight catsuit, as she crawled towards her, hissing like a cat. Nike assumed a fighting stance, ready for the lethal fight.

FINISH THEM: (I'll just finish La Pantera as it's been a month since her post)

Nike's endurance and strength made her withstand her Pantera's strikes, and, although scarred, stood tall towards the end of the fight. After several armlocks and bodyslams, Pantera was reeling, her latex outfit torn and undone to reveal her breasts and her broken arm hanging limp.
"Finish her!" The VIP guests shouted at her from their seats. Nike nodded, and grabbing her adversary with one hand on the throat and the other on her crotch, lifted her body overhead. La Pantera tried to escape, kicking her legs, but Nike's grip was firm, and decided to make a show of her strength by doing military presses while the smaller woman squirmed about. Then, she tossed her towards a meat hook suspended from the ceiling. The hook went right through Pantera's lower jaw and exited her mouth, as she hang there in a most painful fashion, screaming.
Moving underneath, Nike grabbed her bionic tail which was attached like a plug into her anus. Pulling with all her strength, she ripped it out, along with it dragging out several feet of intestine. She hung there for a while, her moans and protests growing fainter as her guts spilled out of her ripped open asshole.
Eventually, the weight made her jaw rip off, as her body fell down to the floor, flat on its back. Through the gaping hole that was left on her face in place of her lower jaw, her tongue gargled out bloody foam, indicating she still tried to draw breath.
Nike decided to finish her off for good, stomping hard on Pantera's exposed stomach with her bare foot, making thick blood pump out of her mouth, and more intestines spill out of her prolapsed anus with a squishy sound, until she squirmed no more, and lay still and dead, eyes rolled back behind her mask.

Next Arena: A jungle biome, full of environmental hazards like carnivorous fauna and flora (anacondas, man eating plants etc). The contestants are dropped in and the event is only covered by cctv and drones.
