About Zerkaa Merch

Joshua “Josh” Bradley (born September 4, 1992 [age 30]), also known online as Zerkaa or Josh Zerker, is a YouTube personality, musician, rapper and the oldest member of the Sidemen.

A number of young stars have made their careers by making internet their main platform. While most of such stars are based in the USA, a few of them have emerged from other parts of the world like Europe and Asia. Josh Zerker is one such English Video gaming enthusiast who has earned a name and made a fortune from YouTube. He used to show interest in video gaming since his childhood. His parents encouraged him by giving him all the support like buying him the latest gaming consoles. Josh started his first YouTube channel called Zerkaa (it was later made into ZerkaaHD when it was made a HD channel).


Josh started uploading YouTube videos in 2008. He initially posted gameplay videos Call of Duty : Modern Warfare 2 but progressed into posting FIFA and other football-related videos. During this time, Josh edited some old videos made by KSI. Josh was supposed to release (but never did) a Call of Duty montage called Illuminate in 2012.

Up until 2014, Josh rarely showed his face on camera and was often seen hidden behind a mask. For a long time he called himself “Josh Zerker” and adamantly defended this alias as his “real” name until 2015, when more and more people learned that his real name was Josh Bradley.

Josh is “officially” the Ultimate Sideman having won The Sidemen Experience in 2014 – a contest in the very early years of the group.
