- Elexis Sinclaire in SiN Episodes: Emergence.

Elexis Sinclaire is the titular main antagonist in SiN video game series. She is a ruthless scientist and businesswoman.

History
At the beginning of SiN, Elexis Sinclaire is a talented biochemist and genetic engineer, CEO of a multi-billion dollar, multinational pharmaceutical company called SinTEK Industries. Elexis was born in 2006 and is 31 years old in the first game. Her biological mother, Diane Kettle Sinclair, abandoned her from an early age. During her upbringing, she learned from her loyal father, Dr. Thrall Sinclair, and eventually became a geneticist at SinTEK.

The way biotechnology blocks the aging process has brought breakthroughs to the company. After her father's mysterious disappearance, she eventually emerged as a supreme power in the company's ranks. Elexis and SinTEK use their chemical and pharmaceutical brands to switch to illegal trading. However, her research developed SinTEK's most advanced chemical U4 with mutagenic properties.

Her current genetic research is shrouded in secrecy. Occasionally there are rumors that she is experimenting in areas that are often considered taboo by the mainstream scientific community. However, SinTEK stands out by transcending normal scientific boundaries, and the world is waiting to see what the next creation of Elexis will be. SinTEK Industries is a virtual bastion due to fierce competition in genetic research.

Even local law enforcement agencies have only brief details about SinTEK scientists and employees. One thing is for sure - Elexis intends to change the world. And she is willing to do this with her every ounce of beauty, charm and genius.

Other media
Elexis also appears in the 2000 anime original video animation, Sin: The Movie. In the film, her father is taken down by the government for his mad biological experiments that she continues (later it is revealed that she actually keeps her father as a huge mutated monster). However, she is also has a lover named Vincent, whom she also turns into a monster and then vivisects. At the end of the film, she falls from a skyrise building, presumably to her death.
