Hacker is the unintelligible non-spoken sidekick of Digby Digworth, as the two attempt to try and find a news scoop but chaos ensues along the way.

After the character became popular, Hacker was added as a weekday presenter at the CBBC office in May 2009, with the puppetry and voice now being performed by Phil Fletcher.

Hacker from that point gained a much more noticeable characteristic, having a much more comedic and sarcastic personality and he now spoke in full words.

[17] Hacker, Cel Spellman and Amberley Lobo provided CBBC commentary on the Russia v Belgium match at the 2014 FIFA World Cup.

Hacker appeared on an episode of Celebrity Mastermind in December 2016, his specialist subject being the Pet Shop Boys.
