King Robbo (born John Robertson, 23 October 1969 – 31 July 2014) was an English underground graffiti artist. His feud with the artist Banksy was the subject of a Channel 4 television documentary called Graffiti Wars, first shown in August 2011. Early works Robbo painted his first train in 1985 and the ‘Merry Christmas’ train of 1988, a joint piece created with "Drax WD", receiving national coverage on ITV News and in The Independent newspaper. Feud with Banksy In 1985, 15-year-old King Robbo painted a graffiti work under the British Transport Police Headquarters on a wall beside Regent's Canal in Camden, London which was only accessible by water. A large full colour graffiti piece, called "Robbo Incorporated", it had over the years become the oldest piece of graffiti in London. Over time, virtually all of his works had been gradually removed from London's trains and walls by authorities, except for this piece. In 2009 however, the English stencil artist Banksy destroyed most of it with a stencil of a workman pasting wallpaper. King Robbo has stated that Banksy was introduced to him for the first time in the 1990s, commenting: "I was at a place called the Dragon Bar on Old Street. I was introduced to a couple of guys who were like '[W]hoa it's nice to meet you!'. When I was introduced to Banksy, I went 'Oh yeah I've heard of you mate, how you doing?' and he went '[W]ell I've never heard of you'...he dismissed me as a nobody, as nothing. So with that I slapped him and went '[O]h what you ain't heard of me? [Y]ou won't forget me now will you?' [A]nd with that he picked up his glasses and ran off." On Christmas Day 2009 Robbo reclaimed his piece from Banksy's defacing by covering the work so the workman appeared to be painting "KING ROBBO" in silver letters. Three days later the letters "FUC" appeared before the word "KING". Tit-for-tat overpainting continued at the site with artwork and insults including a picture of Top Cat leaning on a gravestone with the words "R.I.P. Banksy's career". This incident led to online arguments and a graffiti war with many of Banksy's other works being altered by "Team Robbo" - notable ones including the piece Hitchhiker to Anywhere where the "anywhere" was changed to "going nowhere". In 2014 LDNGraffiti published an illustrated timeline of the feud. In 2015
