Entity Allstars are a dance group who reached the Final of Series 9 of Britain's Got Talent. They received Alesha Dixon's Golden Buzzer. Members include Lewis Platt, who is the brother of Lauren Platt, a past X Factor finalist.
In their audition, the group performed to a mix of classical and hip-hop music. They began their performance in unison, before certain members of the group began to perform solo movements separate from the group. This style of performance continued throughout the piece. Amanda commented that 'It felt so dynamic', whilst Simon remarked 'That's why Great Britain is great'.
In the Semi-Finals, the group began with a slow-motion scene performed to 'Hedwig's Theme', whilst wearing Hogwarts clothing. The act then continued as a 'competition' between members of the group dressed as Draco Malfoy and Harry Potter, whilst the remainder of the troupe performed as 'backing dancers' in unison. Alesha remarked 'You made it so interesting [and] so dynamic', with David adding 'You really lived up to your name you are Allstars'. They won the Judges Vote with 3 votes from Alesha, Amanda & Simon and advanced onto the Final.
In the Final, the group performed to a Gladiator theme. One member of the group performed the main solos, whilst the others performed in unison in the background. Other members of the group performed mini-solos at different points throughout the performance. At the end of the performance, the main soloist jumped onto the Judges' desk with a spear. Alesha remarked 'The energy and the passion and the determination, it was a fight to the end', with Simon adding 'That has to be a chance of being a winning performance'. They ultimately placed 11th overall.
