Angus Cloud, who featured in HBO's hit series Euphoria, has died at the age of 25.

Cloud, who played drug dealer Fezco "Fez" O'Neill in the teen drama, died on Monday at his family home in Oakland, California, said a publicist.

"It is with the heaviest heart that we had to say goodbye to an incredible human today," said the Cloud family.

Cloud attended his father's funeral in Ireland last week and, according to his family, "intensely struggled with this loss".

There was some comfort in knowing he was now "reunited with his dad, who was his best friend", they said in a statement.

"Angus was open about his battle with mental health and we hope that his passing can be a reminder to others that they are not alone and should not fight this on their own in silence," it said.

"We hope the world remembers him for his humor, laughter, and love for everyone."

His cause of death has not been given.

"We are incredibly saddened to learn of the passing of Angus Cloud. He was immensely talented and a beloved part of the HBO and Euphoria family," HBO said in a statement.

"We extend our deepest condolences to his friends and family during this difficult time."

Two weeks ago, Cloud posted a photo of his father on Instagram and wrote: "miss u breh."

Before rising to fame as 'Fez' in the series "Euphoria," Angus Cloud's acting experience was relatively limited, with minor roles in two films, "North Hollywood" and "The Line." Additionally, he made appearances in music videos for artists such as Becky G, Karol G, and Juice WRLD.

However, his fortunes changed when he landed the role of Fez, a high school drug dealer, in "Euphoria." This part proved to be a turning point for Cloud, propelling him into the spotlight and earning him recognition as a breakout star, as mentioned in the Hollywood Reporter. Subsequently, his character's significance was expanded in the show's second season.

Surprisingly, in a 2019 interview with GQ, Cloud revealed that he had no real aspirations to become a star or even pursue acting as a career.

He used to work at a chicken and waffle joint, according to the magazine, and one day was unexpectedly stopped in the street by an agent from a casting company.

"I was confused and I didn't want to give her my phone number," Cloud told GQ. "I thought it was a scam."

After first airing in June 2019, Euphoria quickly became a hit and by 2022 was the most tweeted-about TV show of the decade in the US.

The main character, played by Zendaya, is a 17-year-old who struggles with drug abuse, seen on screen taking the deadly opioid fentanyl and injecting morphine.

In 2022, Cloud defended accusations during an interview with TMZ that the show glorified drug use.

Euphoria creator Sam Levinson said: "There was no one quite like Angus. He was too special, too talented, and way too young to leave us so soon."

Sydney Martin, the model who was rumored to be in an on-off relationship with Cloud, shared broken heart emojis on Instagram after his death was announced.

Cloud's co-star Javon "Wanna" Walton, known in the show as Cloud's adoptive brother, Ashtray, wrote on Instagram: "Rest easy brother."

California congresswoman Barbara Lee lamented the loss of "Oakland's own", in a post on X, formerly known as Twitter,

"His immense talent touched the lives of countless people. His work & legacy will forever live on and make Oakland proud," she wrote.

Actress Kerry Washington also posted on the platform: "You will be deeply missed. Rest in power."
