As announced late last year, former Footballers' Wives star Chucky Venn has been cast in the role of Ray - who hasn't seen Morgan's mum Bianca for a number of years.
Pictured: Chucky Venn as newcomer Ray Dixon.
The new storyline for the Butcher clan begins when young Morgan (Devon Higgs) starts asking some awkward questions about his skin colour. A flustered Bianca (Patsy Palmer) immediately claims that his real father is Barack Obama - but Whitney isn't entirely comfortable with the lie as she watches on.
Whitney (Shona McGarty) also notices that Bianca is strapped for cash, so she decides that it's time to take matters into her own hands by tracking Ray down.
Later in the week, Whitney goes behind Bianca's back by taking Morgan to meet his father at a café - and Ray is blown away as he comes face-to-face with his secret son at last.
As Ray opens up over his history with Bianca, Whitney learns that the fiery mum stole money from him and did a runner - without telling him that she was pregnant.
Now that he finally knows about Morgan, it's clear that Ray wants to be a part of his life - but how will Bianca feel when he starts to become a more regular fixture around the Square?
Show bosses have also teased that Ray will manage to make an impression on some of Walford's other ladies - but who will they be?
When Venn's casting in EastEnders was first announced in November, he commented: "I have had the pleasure of working on many great productions with fantastic artistes such as Morgan Freeman and I have to say working on EastEnders feels like it is up there with the best of them.
"EastEnders is etched in British history and it is an honour and a pleasure to be part of it."
EastEnders airs Ray's first scenes on Tuesday, January 10 at 7.30pm on BBC One.
