ZeRo

ZeRo was born in Chillán in 1995.[8][9] As a child, ZeRo was bullied and placed into a special needs program in school. Due to his family's financial issues and his own anxiety, he dropped out of school for three years. During this time, ZeRo received a Nintendo GameCube and would play speedruns on Super Mario Sunshine, as well as Super Smash Bros. Melee with his older sister.[10]

In 2006, ZeRo began competing in Melee tournaments in his Chilean hometown at a local game store.[11] In the following years, ZeRo regularly traveled between Chile, Argentina, and the United States to compete in regional and international Smash tournaments and events.[12]

In 2011, ZeRo' sister died at age 27 due to complications from a brain aneurysm.[10]

Between 2011 and 2012, after competing in various local and regional Melee tournaments, ZeRo was sponsored by Los Angeles-based vVv Gaming. In 2012, he began competing in professional esports events including Apex,[13] By early 2014, it was estimated that ZeRo was earning approximately US$40,000 a year from a combination of prize money, sponsorships, and Twitch streams.[14]

ZeRo then qualified for the MLG Anaheim 2014 championship bracket and finished in 17th place. During this time, he was ranked by Melee it on Me as the 35th best Melee player in the world.[15] In June 2014, he won the Super Smash Bros. for Wii U invitational at E3, moving up through the winner's bracket and defeating Hungrybox in the game's first-ever official tournament.[16]

In November 2014, ZeRo criticized Diddy Kong's repetitive play style in Smash Bros. for Wii U, claiming that Diddy was "killing the game".[17] However, ZeRo later retracted the statement and stated that Diddy Kong was his favorite character to play with, which eventually led to Diddy being his main character in tournaments.[18]

At EVO 2015, ZeRo defeated Mr. R in the largest Smash for Wii U tournament to date. In the following month, Team SoloMid announced ZeRo as the second player in their Super Smash Bros. division.[19]

At The Big House 5, ZeRo faced off in the grand finals against Team Liquid's Nairo. Despite a narrow escape from losses in the early tournament and a loss during the first set versus Nairo, ZeRo ended with a 3–2 win in the second set.[20]

In MLG World Finals 2015, ZeRo defeated Nakat, StaticManny, Ally, and ESAM, moving on to challenge Nairo for the winner's bracket grand finals. There, Nairo took two sets off of ZeRo, ending ZeRo's reign at 56 consecutive victories.[21]

ZeRo suffered from a growth on his middle finger in early 2016 that required surgical removal, and prevented him from playing Smash for several months.[22]

In January 2018, hours after ZeRo was once again ranked 1st on the Panda Global Rankings v4, ZeRo announced his hiatus from the Smash competitive scene, citing a need for variation in his life and goals.[23] However, during this time he continued to be active in the Super Smash Bros. community and continued streaming on his Twitch channel.

In November 2018, ZeRo simultaneously announced his return to professional competition for Super Smash Bros. Ultimate and his signing to the Tempo Storm esports team.[24] ZeRo announced a year later that he had signed an exclusive streaming rights deal with Facebook.[25]

On July 3, 2020, ZeRo announced that he would be retiring from professional competition following allegations of sending sexual messages to minors when he was 19, and that he would also be ending all of his sponsorships. This includes an incident in 2014, where ZeRo allegedly asked "Katie", a 14-year-old girl at the time, to masturbate with ice and to take pictures.[26][27] ZeRo later made a statement on YouTube, saying he is sorry and is seeking therapy.[28] The following day, Tempo Storm announced that they would be severing ties with ZeRo,[26] with Facebook following suit on July 5, and Twitch on July 23.[29][30] When Inven Global asked the team's CEO, Andrey "Reynad" Yanyuk, if he saw "a world in which ZeRo is able to rehabilitate himself and potentially re-join Tempo Storm in some capacity", he responded:

"I don't know, I don't like to speculate about the future. I just take things one day at a time, you know? I think ZeRo is a very different person today than he was when he wrote some Skype messages at 19 years old. I think he's had a lot of personal growth over the past few years that I've personally seen, so I'm optimistic about his ability to recover."[31]

After months of silence, on March 23, 2021, ZeRo's then ex-girlfriend Vanessa announced on Twitter that he had attempted suicide and was sent in for further care after being treated in a hospital.[32] On April 26, 2021, ZeRo updated to the community that he successfully recovered from the hospital and has no intention to attempt suicide again.[33] On November 16, 2021, ZeRo uploaded a video to YouTube, stating that he was returning to creating content and retracting his previous admission.[34] On November 30, 2021, ZeRo sued his former roommate Jisu for defamation regarding four allegations she made against him in 2020.[35] On September 9, 2022, ZeRo announced that a settlement had been reached in the lawsuit.[36]
