Momoa will be playing an as yet unnamed villain who goes up against Dominic Toretto and his vast crew of street racers, tech geniuses and special agents.
In an interview with GQ, Momoa made some revelations about the role: "It's been hard because people always think I'm just this dude who plays [macho characters].
"But I want to be moved, I want something new. Things are changing, and even the villain roles I'm playing now are eccentric."
He added: "I'm a peacock at the highest level and I'm having the time of my life."
Momoa is best known for playing heroes and antiheroes such as Aquaman and Khal Drogo in Game of Thrones.
His character in Fast X is reported to have pink toenails and Momoa was spotted driving a lavender coloured car during production on the film in Italy.
Fast X sees the majority of the cast from the previous films returning including Vin Diesel in the lead as Dominic Toretto.
Original cast members Michelle Rodriguez and Jordana Brewster will also feature after Brewster was originally left out of the film's script.
As well as Momoa, new additions to the vast cast include Oscar-winner Brie Larson, Reacher star Alan Ritchson and Daniela Melchior while Rita Moreno will portray Toretto's grandmother.
One star not returning to the series is Dwayne Johnson who has had issues with Diesel.
Fast and Furious 10 is directed by Louis Leterrier who replaced Justin Lin after production had already began, reportedly due to disagreements with Diesel.
Fast and Furious 10 will hit cinemas 19 May, 2023.
