'X', real name Earl Simmons, was admitted to hospital after suffering a heart attack on 2 April and had been placed on life support.
Fans have been celebrating the rapper's life and career, with Tyson's most intimidating ring walk doing the rounds in tribute.
On January 16, 1999, 'Iron' Mike faced off with South African fighter Francois Botha - competing for the first time since being hit with a lengthy ban for biting part of Evander Holyfield's ear off in 1997.
MGM Grand Garden Arena was the venue for Tyson's return and his walk to the squared circle was intense.
Tyson, with 'Be Real' on his hat and t-shirt, had a look of pure menace about him. The soundtrack of 'Intro - It's Dark And Hell Is Hot' from DMX, a fellow New York native, could not have been more perfect and led to the whole arena falling silent.
The commentators also didn't know what to make of it and didn't say much, making the whole entrance even more terrifying.
Although it wasn't his most impressive performance, 'The Baddest Man on the Planet' knocked out Botha in the fifth round for a triumphant return to action.
DMX, who had a slew of hits and No.1 albums, made music with such pain and passion that many fighters in boxing MMA and boxing had to walk out to his gritty, gruff tones.
UFC legend Anderson Silva came out to X's track 'Aint' No Sunshine' on a regular basis and it still gives goosebumps.
The newer MMA fans can't really understand the feeling of Anderson Silva walking out to DMX.- :pineapple: (@ProsciuttoJr) April 3, 2021
After hearing news of his death, 'The Spider' took to Instagram to pay tribute.
The Brazilian write: "Today is a very sad day! DMX, I'll be forever your fan! Thank you, you will always be remembered with respect and a lot of affection from me! May God comfort the family! RIP."
