Leffen

He took over his friend’s Warcraft 3 account and kept his username.

Leffen started playing video games such as Mario on controllers when he was around three-years-old. When he was fifteen-years-old, some of his online friends suggested that they meet up in central-Stockholm to play Super Mario Brawl. Asa teenager, he played various games, but primarily stuck with WoW and Super Mario Bros. Brawl. However, when he arrived there, they were still playing Super Smash Bros. Melee. He discovered that he preferred it Brawl and has been passionate about it ever since.

Leffen started participating in professional tournaments in 2011. Although he has experienced a year-long ban in 2014, he didn’t let that slow his pace, as he switched to Ultimate Marvel vs. Capcom 3 until he was allowed to return to Smash Bros. He seemed to have learnt his lesson and also gained more skills, as he soon beat the top players at the time, including Armada and Hungrybox. He was signed on to TSM in 2015 and continues to participate in professional tournaments.
He set up his YoutTube channel on December 8, 2011 and his Twitch account on December 26, 2013.

Leffen has over 5,600 subscribers, which likely generates him about $19,600 USD per month. This excludes revenue from tournament earnings, sponsorships, tips and his TSM salary.
