Gavin Dempsey (born April 11, 1998), also known as Tweek, is an American professional Super Smash Bros. player.
Tweek won three major Super Smash Bros. for Wii U tournaments, 2GGC: MkLeo Saga, MomoCon 2018, and 2GG: Hyrule Saga. He was considered one of the game's top players by the end of the game's competitive run, and was 7th in the Panda Global Rankings 100, which ranked the top Wii U players of all time. He represented multi-esport organization Phoenix1 in several Smash for Wii U events, including his MkLeo Saga victory.
Tweek has won eight major Super Smash Bros. Ultimate tournaments: Let's Make Moves, Glitch 6, Frostbite 2019, Get On My Level 2019, Low Tier City 7, Glitch 8, Smash Ultimate Summit 3, Port Priority 7 and as of January 2023, Let's Make Big Moves 2023.
Super Smash Bros. for Wii U
Tweek began competing in Super Smash Bros. events in 2014. Although he competed in a small number of Super Smash Bros. Melee events, including at Evo 2015, his first high-placed finishes were in Super Smash Bros. for Wii U. He was considered the best Bowser Jr. player in Smash for Wii U in 2015, though he would eventually retire the character in favor of Cloud Strife, the character whom he would use two years later in his first tournament win. In 2016 he had a number of strong showings at major tournaments, including taking third place at Glitch 2 and ninth at Genesis 4, and in February 2017 he was signed by esports organization Phoenix1. The organization, which had previously only fielded competitors in League of Legends, called him "one of the best up and coming talents in Smash". At the time, Tweek was ranked 17th in the Panda Global Rankings, considered the game's authoritative ranking of players.
Tweek's first tournament win would happen six months later when he defeated Gonzalo "ZeRo" Barrios, the then-best Super Smash Bros. for Wii U player in the world, to win Low Tier City 5. Tweek was on a strong run of form going into the tournament, having taken fourth place a month earlier at Evo 2017. His only other win at a major tournament in 2017 would come in November, where he won 2GGC: MkLeo Saga, which was considered a major Super Smash Bros. for Wii U tournament. In the Panda Global Rankings for the first and second half of 2017, Tweek climbed to 12th and then 5th, respectively.
The following year, Tweek put on a series of strong performances, including several tournament wins. He started the year with a second-place finish in Frostbite 2018, followed by wins at King of the Springs 3 and Enthusiast Gaming Live Expo 2018. By this time, he had transitioned to using Bayonetta increasingly in tournaments. Tweek announced in mid-May that he was no longer representing Phoenix1. As a free agent, he won MomoCon 2018 in May and 2GG: Hyrule Saga in June, both also considered major tournaments, then placed second at CEO 2018 in July. As a result of his strong performances, Tweek was ranked the second best Smash player for 2018 in the Panda Global Rankings, behind only Leonardo "MkLeo" López Pérez. By this time, Panda Global listed his main character as Bayonetta, with Cloud Strife and Donkey Kong as secondaries.11:10 Following the release of Super Smash Bros. Ultimate, Panda Global released a list of the 100 best players of all time for Super Smash Bros. for Wii U, which ranked Tweek 7th.
Super Smash Bros. Ultimate
Super Smash Bros. Ultimate was released on December 7, 2018. The game was seen as sharing the "framework and DNA of Super Smash Bros for the Wii U", and Tweek transitioned from Wii U to Ultimate seamlessly, winning both Let's Make Moves and the Sky Ultimate Invitational in the game's first month. He followed those wins with a win at Glitch 6 in January. Shortly after Glitch, he was signed by esports organization TSM, the same organization that elite Melee player William "Leffen" Hjelte represented and that Wii U player ZeRo had represented prior to his retirement.
