The Misfits Gang, also known as the 'ASBO Five', are the main group of characters featured throughout the series in every episode. There are usually five members in the gang (hence the name 'ASBO Five'), but other members have joined them for an episode or two in the past, such as Ollie. More recently, in Series 4, there have been only four members in the gang, with Alex in place of a fifth member. The gang are all stuck in the community service programme, except for one single episode.
