Mun "MMA" Seong Won is a Terran player from South Korea, who is currently playing for Team Acer.
MMA was born and raised in Incheon, South Korea. When he was in elementary school, he was introduced to the original StarCraft, which would become his passion and would later lead him to become a progamer. At first, he wanted to be a soldier, but due to a knee injury he had to be discharged from the army. MMA played as a Terran on SK Telecom T1 from 2008 under the id "Dream.t)1988", although he did not play very many games.
Wings of Liberty
MMA was the first of the new recruits for BoxeR's SlayerS team, whom he knew through his old team SK Telecom T1. He later evolved into SlayerS' ace player, leading people to nickname him the Son of Boxer even to this day.
He has found success in team leagues such as Zotac and GSTL, where he has been a pivotal force in SlayerS's lineup, and is often utilized as an Ace player. In the premiere GSTL February, MMA almost performed a reverse all-kill, taking down 3 opponents from ZeNEX when his team was down 0-3. In the GSTL March, MMA has been very successful, defeating players such as MC and July on SlayerS' path to the finals. He defeated Mvp in the championship match, earning his team the GSTL title and himself the Most Valuable Player Gold Card for his performance. The following GSTL in May, MMA was once again used as the primary Ace player of SlayerS. He helped stage a comeback against fOu in the semifinals and was chosen as the last player to face MvP in the finals where he took out DongRaeGu in the deciding game to earn SlayerS a repeat victory, as well as a repeat MVP Gold Card for himself.
MMA's first individual success in Korea was his run through the GSL Super Tournament. He managed to draw only Terran opponents, including two of his teammates, GanZi and Ryung. With the exception of those two, his other series were fairly close, particularly a comeback from a two game deficit against MarineKing in the semifinals to advance 3-2. Although MMA was the heavy favorite going into the finals, he would subsequently be swept by Polt 4-0.
MMA's next notable finish in Korea would be in the Arena of Legends 1. He dominated his group, winning 2-0 against both NesTea and MC to advance to the round of 4. There, he lost 0-3 to MarineKing, therefore placing third.
MMA would be able to play in the Blizzard Cup due to the fact that Mvp qualified three times, so MMA got a spot by virtue of his 4th place position in the GSL Player Rankings. In the group stages, MMA would tie for first in his group with a score of 3-1, only dropping a game to Polt. He would later get his revenge though, beating Polt and Leenock in the tie breakers to secure first place in his group. In the bracket play, MMA would 3-0 Mvp to face DongRaeGu in the finals. MMA was up 3-0 against DongRaeGu before DongRaeGu started to make a comeback, evening the score 3-3. MMA however would not falter in the ace game and end up winning the tournament, 4-3.
MMA's first Code A qualification, was for GSL March. He eliminated the foreigner Ret 2-0 to advance to the Round of 16. There he was defeated by Killer 1-2. In the subsequent Code A tournament, he quickly took out TopClass and Hyperdub making it to the Round of 8 before falling to Bomber. Entering the Round of 8 was enough to allow MMA to play in the up/down matches where he was defeated by MarineKing 1-2, and HuK 0-2, keeping him in Code A. The following season he was knocked out entirely by falling 0-2 in the first round to Puzzle.
MMA wouldn't return to Code A until 2012 GSL Season 2, falling third in his group and landing in the Ro32 where he would face Line and defeat him 2-0 to advance into the Ro24, meeting KeeN but losing to him 1-2, falling just close to a granted Code S spot, he played in the Up and Down matches, but couldn't win a game and lost 0-3, staying in Code A for the next season.
In the third 2012 GSL MMA would start in Code A vs HongUn, making this HongUn's last match from Code A before retiring , MMA would advance 2-0 and face HerO, few days before the match MMA would enter a controversial fight with SlayerS and would be demoted to the B-Team  just a few days before his match, nonetheless MMA would take a smooth 2-0 win over the Protoss player and continue his Code A run, advancing to the Ro24 where he would play against viOLet, he would beat him 2-1 which put him back into Code S RO32.
During MMA's first Code S season in GSL August after being seeded through MLG, he 2-0'd his group, ending NesTea's undefeated GSL streak. He faced off against Polt in the Round of 16 in a rematch of the Super Tournament final, but lost to the Prime Terran once again, although this time in a close series which ended 1-2 in Polt's favor.
The next season, MMA chose NesTea for his group, not having many choices left. This time, NesTea defeated MMA, but MMA was still able to make it out of his group 2-1, by beating NaDa and KeeN. He defeated asd in Ro16 and followed it up with a 3-2 win over Clide in a hard fought series in the Ro8. In the Semifinals he went up against the IM Terran Happy defeating him 3-1. The finals were held at the BlizzCon, where he would face off against Mvp, the reigning champion, and defeat him 4-1 to win his first GSL title.
During the Group Selection for GSL November, MMA made some controversy when he picked his teammate YugiOh and criticized him. In addition to YugiOh, his group contained another teammate, Ryung, and one of the five Protoss players in Code S, MC. MMA would advance with ease, beating YugiOh and MC to place first in the group. In the Round of 16, he was in Group A with NesTea, HuK, and Leenock. There he convincingly defeated NesTea then Leenock to advance onto the Round of 8.
In the first season of 2012 Round of 32, MMA would sweep his group with 2-0's against GuMiho and Zenio. The Round of 16 group stage went a lot closer than the previous round. With two close wins against Oz and a loss against teammate Puzzle, MMA was still be able to advance to the next round. MMA would go on to meet aLive in the RO8, where he lost 1-3. Because he made it to the RO8, he would be qualified for next season's Code S.
In the 2nd season of the 2012 Global StarCraft II League Season 2/Code S, MMA would be placed in the RO32 Group F with Squirtle, Leenock, and NaDa. MMA would first play Squirtle where he would lose 1-2, he went to the losers match to face NaDa and 2-0'ed him. He would then go to play in the final match versus Leenock where he would lose 0-2 and fall to Code A RO32.

In the finals, he ended up losing 2-1 in the first best of 3, therefore coming in second. Because Mvp already had Code S status, MMA would be offered and receive it instead through the MLG - GSL exchange program.
Due to his high placing in two MLG, MMA got enough points to be one of the top four seeded players at MLG Providence 2011. However, he lost to his rival DongRaeGu 0-2 in the Championship Bracket winners' bracket and was eliminated from the tournament by Leenock losing 1-2, finishing 9th overall.
