Netflix's Cobra Kai fans in disbelief as they learn Ralph Macchio's real age

Cobra Kai fans have been left utterly stunned after learning Ralph Macchio's real age. The popular Netflix series sees Macchio reprise his iconic role as "karate kid" Daniel LaRusso, evolving into a top Miyagi-Do mentor.

As we said goodbye with season 6, fans were treated to a TikTok video showcasing Ralph through the years and revealing that he is now 63-years-old. Back in 1984 on The Karate Kid set, a youthful 22-year-old Macchio had some co-stars questioning his age, according to IMDb.

Now, his seemingly perpetual youth has left fans flabbergasted.

The TikTok video traced the actor's journey from his current age back to his teenage years. The caption on the Curiously TikTok page asked viewers: "From Karate Kid to Cobra Kai Season 6 – which era is your fav?"

Since its release the video has raked in plenty of views and likes, along with a flurry of comments.

One fan was baffled by Macchio's age when he starred as Johnny Cade in the 1983 crime thriller The Outsiders, querying: "He was 21 during The Outsiders?" while another exclaimed: "I literally gasped when I saw he was 21 like he looks 14", reports the Irish Star.

Another TikToker, after viewing the clip, remarked: "Bro started ageing at 32 and stopped at 38."

And there are plenty more comments along those lines - with jokes about him looking "20 years younger than [his] acc (actual) age", claims that "he always looks 20 years younger than his age" or jests that he "never ages."

Another commented: "He's still gorgeous at age 63."

Meanwhile one admirer enthused: "He looks better in his 60s than in his 50s."

A separate user chimed in, comparing him to Paul Rudd – the star who famously portrayed Mike on the hit US sitcom Friends – noting: "Him and Paul Rudd bro they barely/don't age."

Viewers were eager to learn more about the star's personal story.

Born in November 1961 in Huntington, New York, Macchio boasts a mixed Greek-Italian background from his father, Ralph Macchio Sr, and pure Italian roots from his mother, Rosalie Macchio.

He also has a sibling called Steven and is wed to Phyllis Fierro, with whom he shares two children, Julia and Daniel Macchio.

Macchio revealed details about his early years during a candid interview with CBS Sunday Morning, explaining how he channelled his personal uncertainties into the iconic Daniel LaRusso character in The Karate Kid: "I think maybe I had certain insecurities.

"I always looked young for my age which is now paying dividends or so far so good, despite my lower back not getting the memo or my knees. But I think there was a bit of growing up.

"I was always kind of the smallest in the class, the youngest looking and when everybody else was maturing and being the star football player or the greatest looking or whatever, I was kind of a little scrawny kid.

"Arguably kind of cute but scrawny so I had a bit of insecurities about myself and I used that when designing Daniel LaRusso, using those elements I put up this cocky front to cover something I might have felt when I was going through adolescence."
