Jason Zimmerman

Mew2King finished in 1st place in Melee singles at Smash Summit 6 in May 2018. Mew2King did not lose in the bracket stage, managing to defeat Armada twice, including during the grand finals. He became the first player to win a Smash Summit event outside of Armada and Hungrybox.

In Melee Mew2King primarily plays Marth, Sheik, and Fox, while he plays Meta Knight in Brawl. He uses his namesake character Mewtwo, as well as Fox and Mario, in Project M and specializes as Kirby in Super Smash Bros. 64. In Super Smash Bros. for Wii U, Mew2King's primary character is Cloud. Mew2King's extremely methodical style of play, as well as his knowledge of frame data in Melee, has earned him the nickname The Robot. He is known to play Melee using a claw-like grip on his controller. For his skill across every Smash Bros game, he is regarded by some as the greatest Smasher of all time. From May 2016 to January 2020, he was a member of the professional eSports organization Echo Fox.

Mew2King finished 9–12th in Melee singles at GENESIS 3 in January. In early April Mew2King left COGnitive. On April 17, 2016, Mew2King joined Echo Fox.

Mew2King has supported Pastime Gaming and Most Valuable Gaming since late 2014, and started working as a business manager for the latter. By late 2014 to early 2015, Mew2King began focusing his time on Super Smash Bros. for Wii U and online streaming and plans on playing fewer online tournaments due to hand problems. His tournament placings have also declined, placing tied for 9th at Apex 2015. In April 2015 he became a member of esports team COGnitive Gaming. Around June 2015, Mew2king suffered a hand injury and missed CEO 2015 and EVO 2015. He did however attend Super Smash Con in August 2015 where he placed 2nd after losing to Leffen. On August 31 he defeated Leffen in the grand finals of PAX Prime 2015, thereby ending the streak of Swedish players winning national tournaments. At Paragon Los Angeles 2015, Mew2King placed second, losing to Mango in Grand Finals.

From May 2014 – November 2014 he lived in Los Angeles, California with YouTube gaming personality Sky Williams, who houses several other professional gamers. In early 2015, Mew2King moved to Phoenix, Arizona. In summer 2015, he moved to Florida. Zimmerman is a full-time video game player who streams on Twitch and attends tournaments almost every week. He is a co-owner of video game tournament organizing company Most Valuable Gaming. He was included in the Forbes 30 Under 30 "Games" List for 2019.

For most of 2013, M2K had not won a major tournament all year until he went on a winning streak where he won virtually all of his fights, including against Mango, whom he had not beaten for several years. In 2014, Mew2King lost to aMSa in winners quarters and Armada in losers finals at Kings of Cali 4.. Mew2King finished 2nd to Mango at Big House 4 in Romulus, Michigan. After a complex leveling game, Juan "Hungrybox" Debiedma defeated Zimmerman at Paragon Orlando 2015.

Zimmerman is diagnosed with Asperger syndrome, obsessive–compulsive disorder and attention deficit hyperactivity disorder and has suffered from "periodic depression" during his career. He has attributed much of his social growth to the Smash community.

A 2009 photo of Mew2King getting kissed by a girl at Tipped Off 5 has become a widely circulated viral image across the internet.

From 2007 to 2014 Mew2King was member of Empire Arcadia (EMP), a company that has also sponsored e-sports players such as Justin Wong. He left the organization after having issues with back payment from the organization. Zimmerman alleges that since 2009 EMP president Isaiah "Triforce" Johnson has owed him "US$ 5k total more/less" and has lent Johnson more than US$ 1,000. From 2011 to 2014 Mew2King was sponsored by CLASH Tournaments (CT). From 2012 to 2014 Mew2King was signed with Vancouver-based Play-For-Keeps, an online e-sports betting service.

Mew2King's handle comes from the Pokémon Mewtwo. Zimmerman grew up in Cinnaminson Township, New Jersey and is a 2007 graduate of Cinnaminson High School. He attended Lorain County Community College before transferring to Camden County College, from where he has an associate degree in game design/computer science. Mew2King says that he had to do an additional half-year of school again because several credits would not transfer. He is uninterested in pursuing a bachelor's degree.

Mew2King began competing in tournaments in 2005 at the age of 16. Kashan "Chillindude" Khan described M2K as having little natural aptitude for the game, becoming good through practicing a lot. During 2006, Mew2King went from being relatively unknown to being one of the best players in the game. In 2004, he spent over 2,000 hours with help from SuperDoodleMan collecting data about various attacks and movements in Melee. In 2007, he managed to place 9th at EVO World 2007. Zimmerman was considered the best Melee and Brawl player from 2008–2009. From 2010–2014, his tournament placing declined and he began losing to improving newer players. Zimmerman and Wyatt "ADHD" Beekman, were banned by Major League Gaming from competing in MLG Dallas 2010, after the two had allegedly conspired to manipulate brackets at Brawl event at MLG DC 2010. The ban came after ADHD had stated that he paid Mew2King US$ 300 to lose the loser's bracket final, a violation of MLG rules. MLG dropped Brawl from their pro circuit at the end of 2010.

Jason Sheldon Zimmerman (born February 5, 1989), known by his gamertag Mew2King, commonly shortened to M2K, is an American professional Super Smash Bros. player from Cinnaminson, New Jersey.

Brawl players. He is also a skilled player of Super Smash Bros. for Wii U, Super Smash Bros. Ultimate and Project M.
