Wun Wun is a '.io'-centred (since his content comprises of games with .io in their domain, namely Diep.io, Agar.io and Slither.io) YouTuber who began recording YouTube videos on June 22, 2015, designating him as one of the first YouTubers in the genre. Presently he retains over half a million subscribers and almost 100,000,000 views (currently 600,000+ subscribers). His current name is not known, as is much of his personal details.
Wun Wun's first video was uploaded on June 2015—he began because, as remarked in his 'Agar.io - Thank You for over 200k Subscribers' video, he couldn't find any skilled Agar.io videos on YouTube. Thanks to the subreddit /r/agario, Wun Wun accumulated around a hundred or so views on his videos. On the urge of giving up, Wun Wun uploaded his Team Turnaround video, which received a relatively unprecedented large amount of views and was the 'foundation for everything to come', in his own words. This video remained nonpareil in terms of video views until the upload of 'Last Man Standing', which received 1.2 million views in a single day.
Their first videos were recorded in 1080p and had added music in the video; as their channel grew, Wun Wun's quality had an increase, with captions and an evident increase in editing. Wun Wun's name is derived after the Game of Thrones character, which he stated was the first thing that came into his head when thinking of a username.
