Daniel George L. Bull (born 27 March 1986) is a British rapper and songwriter known best for his songs about video games, which he publishes on his YouTube channel.

He used to collaborate with fellow artist Dave Brown ("Boyinaband"). However, he now collaborates with another fellow artist, Greg Holgate ("The Stupendium") on music instead. He has also collaborated with fellow YouTube personalities such as Dan "Nerdcubed" Hardcastle, Michelle 'The RPG Minx', Markiplier, and Adam Montoya. Bull's music was featured in the British press as part of attempts to save BBC Radio 6, campaign against the Digital Economy Bill, and protest in favour of filesharing. He was diagnosed with Asperger syndrome, which is referenced in some of his songs, such as "A Portrait of the Autist".
