Jess (Karla Crome) and Finn (Nathan McMullen) join the cast in a main role at the beginning of series four.
Curtis originally had the power of time manipulation, allowing him to travel back and change events, stemming from his regret over the incident that led to his community service.
Portrayed by Natasha O'Keeffe, Abbey Smith[2] believes she lost her memory in the storm, since she can't remember her life before it.
A barman who works with Curtis, he first appears in the fourth series and behaves oddly around women, including Jess when she asks him out.
She suspects that the Misfits are involved in Tony's disappearance and she begins leaving threatening messages in group's lockers.
At the end of the episode, the Misfits wrap her in blankets, row out to the middle of the canal, and dump her weighted body into the water.
Thinking she has been brought back to take revenge upon the gang she tricks Simon into kissing her, filming it on his phone and sends it to Alisha.
In episode 4, it is revealed that he was the policeman who arrested Curtis for drugs possession, resulting in his community service sentence.
Superhoodie, played by Daniel Ilabaca, first appears in one of Simon's videos, helping a member of the public, and features on posters both on the E4 website game and in the show.
Superhoodie returns in the first episode of the second series, dressed in black, initially studying a room full of photos of the Misfits along with five large digital clocks counting down to an unspecified target.
He throws a paper aeroplane from a building across a river to Kelly, informing her to go to Nathan's grave where she discovers his immortality.
In the second episode of the second series, he shields a temporarily mortal Nathan from his brother Jamie's exploding car, causing him to be apparently hurt quite badly by shrapnel, though he manages to escape.
Having repeatedly saved Alisha from danger, Superhoodie reveals himself to be a future version of Simon to her, and makes her keep his identity hidden.
Alisha reveals Superhoodie's true identity to Simon after the Misfits go public, as well as her relationship with him, but this timeline is erased by Curtis.
He has a very relaxed, somewhat bored attitude towards the group, and although he seems to understand when they are lying to him, he doesn't let it bother him if it happens beyond his working hours, at which point he washes his hands of all responsibility and goes home.
The Misfits unintentionally kill him on his first day of work when they assume that he is the disguised Lucy, but Curtis is able to undo the event.
In the second series' penultimate episode he overhears Nathan, Curtis and Simon talking about their powers and sells them out to the media before leaving the country.
[4] MSN News opined that Shaun was played "brilliantly" and questioned if the fact that he makes it clear that he "couldn't care less about the young offenders" has anything to do with him having "survived longer than any of his predecessors".
Debnath added that out of all previous probation workers he was "the most memorable because of his apathetic attitude towards youth offenders and the rehabilitation system".
[7] Nikki, played by Ruth Negga, is a young woman with an unspecified heart condition who becomes involved with the gang.
She is introduced in the second episode of the second series when Curtis' inverted power causes him to 'flash forward' and experience a future event, a romantic encounter on a rooftop with Nikki.
The Misfits then encounter her in the present when they break into her flat, mistakenly believing it was the residence of Superhoodie, who had led the group there.
When Nikki feels she is about to teleport, she experiences a sensation similar to falling, or being drawn backwards, and then she immediately shifts to her new location.
The couple plan to travel together, but Nikki is shot and killed by an armed robber under the orders of a priest named Elliot pretending to be Jesus.
Greg, played by Shaun Dooley, is the gang's fifth probation worker, replacing Laura, who was bitten by a zombie and subsequently killed by Rudy before she could start her first day.
[8] Digital Spy's Morgan Jeffrey said the first episode of series 4 begins to feel like the show has "begun to find itself again", which is "compounded with the magnificent arrival of sinister new probation worker Greg".
As a result of the storm, her desire to better embody her characters transformed her into one of her roles: Lola, a manipulative seductress with a troubled past.
As Lola, she seduced men into killing her ex-boyfriends, eventually setting her sights on Curtis while pretending to be a trainee probation worker.
This results in Curtis getting shot, but his current situation as a zombie leaves him invulnerable allowing him to bite and then murder Lola.
Digital Spy's Catriona Wightman said Lola is "so clearly bad news that she should really wear a hat with a flashing warning sign.
