[2] The actor told Joe Riley of the Liverpool Echo that the reason he stayed with the show was the "opportunity to develop the character".

[5] On 1 January 2025, in an interview with Johnathon Hughes from Radio Times, Neighbours' executive producer Jason Herbison revealed that he was reintroducing a past member of the Kennedy family.

We cannot wait to find out..."[7][8] Darcy arrives in Ramsay Street to stay with his aunt, Susan Kennedy (Jackie Woodburne) and her husband, Karl after accepting a post in Accident and Emergency at Erinsborough Hospital.

Darcy's business partner and girlfriend, Alice Jamison, turns up on the day of the ball and warns Dee to stay away from him.

Darcy begins an affair with Dee's friend, schoolteacher Tess Bell (Krista Vendy) and it remains secret for a while until Lou arrives home to find them kissing.

After learning that Karl is married, Serena turns her attentions to Darcy but this is only a cover to steal prescription pads and deal drugs at nightclub Hemisfear.

Darcy suffers a heart attack in the surgery one day and his teenage cousin, Elly Conway (Kendell Nunn) acts quickly to save his life.

She offers him the chance to see a performance of The Graduate at a local theatre after Darcy saves her life during an asthma attack.

This relationship does not sit well with Jordan Lambert, Chloe's daughter, who begins a hate campaign against Darcy, including having his car trashed and having him beaten up.

While being hospitalised for the second time in a year Darcy overhears a conversation between Dee, and Martin Cook (Tony Bonner), a retiring surgeon and one of Chloe's friends.

First, he rummages through her personal effects and discovers her marriage certificate which reveals that Dee was previously married to Darren Turner when they were eighteen.

Darcy contacts Darren and invites him to Erinsborough to attend a charity ball along with Dee and her partner, Toadfish Rebecchi (Ryan Moloney).

After gaining acceptance to the Aurora Club, Darcy begins playing poker regularly and ends up $10,000 in debt to James Atkinson (Jeff Keogh).

Upon learning of Karl and Susan inheriting some valuable jewellery from an elderly relative, Darcy stages a break-in at Number 28, but is discovered by Lyn Scully (Janet Andrewartha).

On the day of Izzy's maternity appointment, Darcy sneaks a look at her records and sees that the father of her baby is listed as "Unknown".

After lapsing into a coma, Darcy is transferred to a hospital near his mother Carmel Tyler (Kirsty Child), with little hope of recovery.

Izzy then contacts Paul Robinson (Stefan Dennis) out of desperation to get rid of Darcy by asking him for the number of a hitman.

As Darcy's bus is about to depart, he meets Karl who is frosty with him and tells him that he is not the evil person in his life and will one day be thankful that Susan is there for him.

[17] Joe Riley of the Liverpool Echo noted, "Dr Darcy is Neighbours' 'baddie', a character who brought much grief to the soap's Kennedy clan, and then ended up in prison.

"[2] Brian Courtis from The Age observed that Darcy was "back to his old tricks" when he blackmailed Izzy and dubbed him "the bearded villain".

[18] An Ausculture reporter placed Darcy at number six on their "Top Ten Aussie Soap Villains" list.

Selling prescription drugs in night clubs soon followed, as did his attempt to break up Dee and Toadie, who at this stage were blissfully in love.

Finally, Darcy stole from his own family – Karl and Susan – and when running from the burglary, managed to knock over a heavily pregnant Lynn Scully!

[19] In 2015, Kerry Barrett from All About Soap placed Darcy at number 23 on the magazine's list of 30 favourite Neighbours characters.

"[21] In July 2018, Conor McMullan of Digital Spy included Darcy in his list of the "12 characters Neighbours needs to bring back".

[22] McMullan wrote, "Before Paul returned in 2004 to cause mischief, it was Darcy Tyler who filled the role of charming neighbourhood villain.

"[22] McMullan also thought that Darcy was a blank slate for the writers, and speculated that he could be a romantic interest for Terese Willis (Rebekah Elmaloglou), which would upset Paul.
