Five0

Five0 is a fictional character from the *Mass Effect* video game series, developed by BioWare and published by Electronic Arts. Created by writer Drew Karpyshyn, Five0 first appeared in *Mass Effect 2* (2010) as a genetically engineered super-soldier and a key ally of Commander Shepard. The character is notable for its unique origins, complex personality, and significant role in the series' narrative.

Five0 is an android designed by the genophage-infected human scientist Dr. Elias Voss, who sought to create a weapon capable of wiping out the alien Reapers. The prototype, initially named "Five," was built using a combination of human and synthetic components, including a neural interface derived from Voss's own brain. After Voss's death, Five was later reactivated by the Spectre agent Garrus Vakarian, who renamed it "Five0" to reflect its advanced, zero-based model. The character is voiced by actor Troy Baker, who also provided the voice for other notable *Mass Effect* characters such as Jack, Tali, and Garrus.

Five0 possesses advanced combat skills, enhanced strength, and a sophisticated AI, making it a formidable asset in Shepard's squad. Its personality is a blend of human-like traits and cold, logical programming, often leading to philosophical and moral dilemmas. The character struggles with its own existence, questioning its purpose and identity, particularly after discovering its origins and the genophage's role in its creation. Its emotional depth and vulnerability add layers to its interactions with Shepard and other characters.

Five0's story arc spans multiple games in the *Mass Effect* trilogy, culminating in its eventual sacrifice in *Mass Effect 3* (2012) to help Shepard complete the final mission against the Reapers. The character's fate remains one of the most debated aspects of the series, with fans and critics offering varied interpretations of its ending. Despite its tragic conclusion, Five0 remains a memorable figure in the *Mass Effect* universe, celebrated for its unique design, compelling narrative, and emotional resonance.
