ZeRo

Gonzalo Raúl Barrios Castro (born April 17, 1995), known by his gamertag ZeRo, is a Chilean professional Super Smash Bros. player and streamer. He was considered the best Super Smash Bros. for Wii U player in the world throughout his career, with a record-breaking 56 consecutive tournament wins in the game from November 2014 to October 2015, including high-profile tournaments such as EVO 2015 and The Big House 5. Prior to the release of Super Smash Bros. for Wii U, he was a top ranked Super Smash Bros. Brawl and Project M player. His best known characters are Diddy Kong in Super Smash Bros. for Wii U, Pit in Project M, Meta Knight in Brawl, and Fox in Melee.

ZeRo retired from professional competition in January 2018 to focus on streaming and "close the chapter" with Super Smash Bros. for Wii U. Following allegations of sexting two minors in 2014, ZeRo's sponsors cut ties with him in July 2020 due to his admittance to the allegations. In September 2022, ZeRo settled a defamation lawsuit he had filed against Jacqueline "Jisu" Choe in response to her allegations.
