Sixteen-time world champion wrestler John Cena announced his retirement Saturday at WWE's Money in the Bank at ScotiaBank Arena in Toronto, which Cena said was the "perfect" place to make the announcement.

In recent years, Cena has shown off a towel that said "Never give up." 

This time, it said, "The last time is now," a reference to his entrance song, "The Time Is Now."

Cena also wore a shirt that said "The Last Time Is Now Tour" and "John Cena Farewell."

Cena said he would compete at next year's Royal Rumble, Elimination Chamber and WrestleMania, which will be his final events. Chants of "Thank you Cena" roared through the crowd afterward.

"Thank you for letting me play in the house you built for so many years," Cena told the crowd.

Now a Hollywood superstar, Cena made his WWE debut in 2002 and quickly became a fan favorite. His first dominant shtick was as a trash-talking rapper when he was nicknamed the "Doctor of Thuganomics."

Two of his most famous matches were at back-to-back WrestleMania events in 2012 and 2013, both of which came against Dwayne "The Rock" Johnson. Cena lost the first but won the second.

Cena has been a part-timer the last five years. His most recent return, before Saturday, came on night two of WrestleMania XL when Cody Rhodes dethroned Roman Reigns as the undisputed WWE champion.

He won his first of 16 world championships at WrestleMania XXI in 2005 at the age of 28.

Outside the ring and film, he is known for having granted the most wishes for the Make-A-Wish Foundation, granting close to 700.

Because of his in-ring success and popularity that was unmatched throughout the 2010s, he's widely regarded as one of the greatest WWE performers of all time and is often placed on hypothetical WWE "Mount Rushmore" lists.

Cena has headlined WrestleMania five times, and since next year's in Las Vegas will be his farewell, it's fair to assume he will headline a sixth.
