The following is a list of characters that first appeared in the ITV soap opera Coronation Street in 2006, by order of first appearance.

Aadi Alahan, who first appears on 13 January 2006, is introduced alongside his twin sister Asha Alahan (Tanisha Gorey) as the newborn children of Sunita Alahan (Shobna Gulati) and Dev Alahan (Jimmi Harkishin).^[1] Aadi and Asha are originally portrayed by triplets Hannah, Harris and Ria Ahmed. The characters were written out following Gulati's decision to leave the soap and depart in February 2006.^[2] The character, along with Sunita and Asha, was reintroduced in 2009 with the role recast to Zennon Ditchett.^[1] Ditchett opted to leave the show in 2019 to focus on his schooling, so the role was recast to Adam Hussain, who first appears on 15 April 2020.^[3] Aadi features in a new story following his recast as Asha becomes the victim to a sexting scandal.^[3] Hussain expressed his excitement at joining the soap and wanted to develop his "own twist" on the character.^[3] Hussain and Gorey were friends prior to his casting, which he thought assisted the portrayal of the twins' relationship.^[3] Gary Gillatt of Inside Soap praised Hussain's casting, commenting, "The new Aadi Alahan is really well cast. He has the same cocky swagger as his dad."^[4]

Aadi was born in January 2006, just before Asha. In March 2006, Sunita still hadn't got back together with Dev and decided to leave the Street with Aadi and Asha. In late 2009, Aadi and Asha returned when Sunita resumed her relationship with Dev. They moved into Dev's flat in March 2010, after Dev and Sunita reconciled. Aadi and Asha thought it was funny if Aadi went out onto the balcony of the flat, however, when Sunita tried to get him in she couldn't and Dev broke the handle when he tried to open the closed balcony door. After many attempts they failed, though Graeme Proctor (Craig Gazey) was riding by and came to the rescue just as Sunita was going to call 999. In April 2013, Aadi and Asha lost their mother when Sunita died from her injuries following a fire in the Rovers - the fire being started by her ex-boyfriend Karl Munro (John Michie), who also turned off her life support machine at hospital. Following a video of Asha undressing for her crush, Corey Brent (Maximus Evans), being spread around the pupils of Weatherfield High by Kelly Neelan (Millie Gibson), Dev was dissatisfied by the headteacher response, and enrolled Aadi and Asha into Oakhill School.

Asha Alahan played by triplets Hannah, Harris and Ria Ahmed in 2006^[2] and Tanisha Gorey since 2009, is one of the twins born to Sunita (Shobna Gulati) and Dev Alahan (Jimmi Harkishin), alongside her twin brother Aadi Alahan (Zennon Ditchett / Adam Hussain) in January 2006.

Before the birth, Sunita had learnt that Dev had fathered children by several different women. Devastated, she left Dev after deciding she could no longer trust him and had even considered having a termination rather than be a single mother.

Dev had hoped for a reunion once the twins were born but after initially allowing him in the delivery room, Sunita barred him from all contact and only accepted help from him when he was too exhausted to refuse. Seeing how well Dev coped, Sunita briefly flirted with the idea of a reunion but was furious when she discovered Dev had registered the births behind her back and realising she still couldn't trust him, took Aadi and Asha and moved back in with her family.

Sunita subsequently divorced Dev, but they kept in regular contact. By December 2009 she was engaged to another man named Matt and living with him in the house she'd bought with Dev prior to their separation. Matt had taken on the responsibility of Aadi and Asha and they quickly became comfortable with him as a father figure.

After Dev discovered Sunita's engagement, he began making visits to her house and trying to spend more time with Aadi and Asha, not wanting them to forget him. In January 2010, Asha fell ill and Sunita feared that she had meningitis after discovering she had spots and high temperature. Dev rushed to her side and although the doctor from the medical centre confirmed it was just a virus, the incident brought them closer together. Shortly afterwards, Sunita ended her engagement to Matt and resumed her relationship with Dev and by March 2010, they were living together with Aadi and Asha at Dev's flat. Another move soon followed to where the Alahans made their family home.

The family unit was disrupted in July 2012 after Sunita's affair with Karl Munro (John Michie) was exposed, leading Dev to move out and Karl to move in with her, Aadi and Asha. Aadi and Asha did not like Karl very much and Sunita soon got fed up of his laziness and regretted throwing away her marriage for him. By March 2013, Dev and Sunita were on the brink of another reunion and leaving for a fresh start away from Weatherfield when Sunita was critically injured in a fire at the Rovers. After a couple of weeks, Sunita died in hospital and it later transpired that Karl was responsible for the fire and removing her breathing tubes.

Dev struggled to cope with Aadi and Asha alone but Mary Taylor (Patti Clare) offered him a helping hand and soon became a nanny to Aadi and Asha. Several girlfriends came and went over the next few years - including Julie Carp (Katy Cavanagh), Erica Holroyd (Claire King) and Gina Seddon (Connie Hyde) but Mary remained a constant in Asha and Aadi's lives.

In 2019, Asha began to rebel against Dev, such as sneaking out to a party he had forbidden her from going to. Dev assumed this was down to teenage hormones and believed an extended visit to India to stay with family would be beneficial. When they returned, Asha was more withdrawn and began spending a lot of time in her bedroom and when she did go outside, she remained covered in long clothing. When Asha returned to school in September 2019, her friend Amy Barlow (Elle Mulvaney) became increasingly concerned about her, especially after discovering a bloodstain on her sleeve. When Amy confronted Asha, believing she was self-harming, Asha revealed that she had actually been using a skin bleaching product in the hope of making her skin lighter. Amy was horrified by Asha's burnt skin and Asha assured her she would stop to prevent her telling Dev but secretly continued applying the cream.

Running out of the product, Asha was desperate for money to get some more, even accepting Dev's ultimatum that she would have to work for extra money at the kebab shop, but when he refused her an advance on her wages she resorted to stealing his credit card to buy some more lightening cream but Dev soon discovered the fraud. When confronted, Asha lied that she had used the money to buy make-up and Dev furiously punished her but his suspicions were aroused when a package arrived for her and opened it, discovering the skin lightening cream and ripped posters of light-skinned Bollywood actresses off Asha's wall in anger. Realising that Asha was full of self-loathing, Dev took her to Dr. Gaddas (Christine Mackie) who recommended counselling sessions. At the same time Asha began a relationship with Corey Brent (Maximus Evans).

Corey later ended the relationship but Asha still liked him and in an attempt to impress him, undressed during an online video chat, which he recorded. Kelly Neelan (Millie Gibson) later became aware of the video's existence and after a disagreement at a party held by Amy, in which Asha refused to stick up for Kelly, she spitefully shared it on social media. Asha was dealt a further blow when she learnt the video had been uploaded to a porn site. Asha even became desperate to leave Weatherfield High because of the incident but was persuaded not to by Dev.

Detective Sergeant Phil Campbell is a police officer. Campbell is first seen investigating a hit-and-run accident in which an elderly man was killed. He arrests Steve McDonald (Simon Gregson) for causing death by dangerous driving and Steve implicates his girlfriend Ronnie Clayton (Emma Stansfield) who is the actual culprit and is subsequently arrested. The following month, Campbell questions Danny Baldwin (Bradley Walsh) on suspicion of fraud after it is revealed he had forged a will in order to get his father Mike (Johnny Briggs), who suffered from Alzheimer's disease, to leave him his factory. Campbell arrests Tracy Barlow (Kate Ford) and charges her with assaulting Charlie Stubbs (Bill Ward). After Charlie dies of his injuries, Campbell charges Tracy with murder. Campbell questions Tracy's neighbours Claire Peacock (Julia Haworth) and Gail Platt (Helen Worth) both of whom claim Charlie was subjecting Tracy to domestic violence and abuse. Campbell also questions Charlie's employee Jason Grimshaw (Ryan Thomas) who tells them that Tracy staged a deliberate row in order to get the police involved. David Platt (Jack P. Shepherd) later visits the police station and tells Campbell that he witnessed Tracy kill Charlie in self-defence after he had attacked her with a knife. David also tells Campbell that Charlie had attempted to abduct him in his van and had also attempted to drown him in his bathtub. Campbell later speaks to Liam Connor (Rob James-Collier) who witnessed the abduction attempt and Maria Sutherland (Samia Ghadie) who witnessed the attempted drowning and they both back David's story up. Campbell was last seen investigating the arson attack at Leanne Battersby's (Jane Danson) restaurant "Valandros" committed by chef Paul Clayton (Tom Hudson). After Paul reports himself and Leanne to the police, Campbell arrests Leanne and questions her but her boyfriend Dan Mason (Matthew Crompton) gives her an alibi.

In October 2004, Cargill played a police officer called DC Paul Campbell, who arrested Dev (Jimmi Harkishin) and Sunita Alahan (Shobna Gulati) on their wedding day, Dev on suspicion of being an illegal immigrant and Sunita for falsely marrying to gain a visa. It is not known whether this was supposed to be the same character under a different name.

Mr. Griffin is the Head Teacher at Weatherfield High who commonly appears in storylines concerning David Platt (Jack P. Shepherd) in 2006 when he began to play truant from school and when he claimed that he was being bullied by three lads the year above him, whose names he revealed under pressure from Griffin. He appears throughout 2007, when he has a meeting with Cilla Battersby-Brown (Wendi Peters) regarding her terminal cancer diagnosis and how it had affected her son, Chesney Brown (Sam Ashton) at school, and again when he visits the Platt family home, 8 Coronation Street after David set fire to one of his exam papers. He appeared again two years later when Chesney's sister Fiz Brown (Jennie McAlpine) was about to punch Kenzie Judd (Jack Cooper) for bullying him.

After a seven-year absence, Mr Griffin reappeared on 30 September 2016 at a meeting to deal with Lauren (Shannon Flynn) for bullying Bethany Platt (Lucy Fallon).^[5] Mr. Griffin returns in 2020 in a meeting with Dev Alahan (Jimmi Harkishin) regarding a fight involving Aadi Alahan (Adam Hussain) and Corey Brent (Maximus Evans). Where Dev announces he is taking both Asha Alahan (Tanisha Gorey) and Aadi out of Weatherfield High and is moving them both to Oak Hill.

Frederick Thomas "Freddie" Peacock (also Thomas Duncan Peacock) is the son of Ashley (Steven Arnold) and Claire Peacock (Julia Haworth). On Christmas Day 2005, Claire tells Ashley that she is two months pregnant, and months later, Freddie is born on 17 July 2006. Claire suffers from post natal depression after Freddie is born, refusing to believe that Freddie is her child. On one occasion, she pushes his pram into the path of an oncoming vehicle and tries to return him to the hospital. She is sectioned until she is well enough to come home.

In October 2006, Claire announces that she would like to change his name from Thomas to Freddie, after his paternal grandfather Fred Elliott (John Savident) who died the week before. In December 2006, he is christened Frederick Thomas with Eileen Grimshaw (Sue Cleaver) as godmother and Roy Cropper (David Neilson) as his godfather.

In May 2007, a fire starts in Freddie's bedroom. Claire is rescued from the burning building but Freddie is not found until later that day, wrapped up in a local park. It is revealed that the fire was started deliberately by use of an accelerant. Originally, this storyline was to last several months but was rewritten to avoid upsetting the family of Madeleine McCann, who disappeared two weeks previously. In September 2007, the identity of Freddie's abductor is revealed to be Claire's former friend, Casey Carswell (Zoe Henry). Casey abducts Freddie and takes him to the balcony of her flat where she threatens to jump with him. Freddie is rescued unharmed and Casey is arrested.
