Simon was sentenced to community service for attempted arson which leads to him gaining the power of invisibility, reflective of his personality in that he often feels ignored.

[2] Rheon later said that "Director Tom Green and I decided we’d base him on Ian Curtis, so he’s cool and has his own story, he’s the kind of character you really get to know if you talk to him about music, something that he really cares about.

Nervous to speak up, but desperate to make friends, Simon tries his hardest to be heard and accepted by the others, which helps to fuel everyone else’s suspicion he’s a little odd.

[8][9] MSN News described the character saying "Simon is a shy, twitchy sci-fi geek who is constantly the butt of everyone else's jokes".

[13] At some point before Simon's community service, he is in a mental institution along with Lucy (Evelyn Hoskins).

The group's probation worker, Tony (Danny Sapani) is also caught in the storm and becomes crazed.

Tony attacks the group and in self-defense, Kelly Bailey (Lauren Socha) kills him.

She finds a video in which Nathan Young (Robert Sheehan) professes the group's part in Tony's death.

Lucy is infatuated with Simon and she becomes angry that he didn't remain in contact with her after he left the institution.

Lucy decides to impersonate Simon and hand herself in to the police in the hope he will be sent back to the mental institution with her.

[14] Alisha Daniels (Antonia Thomas) meets Superhoodie and later realises he is a future version of Simon.

A follower of Elliot (Edward Hogg) kills Nikki (Ruth Negga) and the group realise they must get their powers back.

Elliot is killed accidentally and the group take his money, using it to buy completely new powers.

[24] Simon stops Peter (Michael Marcus) from being mugged while he is wearing Superhoodie's costume.

[26] Simon helps Rudy Wade (Joseph Gilgun) find Leah (Amy Manson) after she gives him a super powered STD.

[27] A medium called Jonas (Mark Heap) tells Simon that a spirit wants to contact him.

Jonas brings back the spirits of Sally, Tony and Rachel (Jessica Brown Findlay).

Sally attempts to murder Alisha to hurt Simon, but Tony stops her and the pair move onto the spirit world.

[29] Rheon was nominated for Outstanding Actor in the fiction category at the Monte-Carlo Television Festival in 2011.

[31] Tim Dowling of The Guardian described him as the "weird one" of the group of "foul-mouthed young criminals".

[33] Neela Debnath, writing for The Independent, commented that even though in a parallel universe the Nazis won the war the characters remained the same where Simon worked for the Nazis but "was conflicted, on the one hand he had to follow orders but on the other hand he found it difficult because he knew that what he was doing was wrong".
