UFC legend Cain Velasquez will face Brock Lesnar in a WWE ring after the showdown was confirmed at an explosive press conference in Las Vegas.
The two former kings of the Octagon were both present alongside Tyson Fury and Braun Strowman in Sin City for successful announcements.
Velasquez, 37, will make his WWE debut against the 42-year-old at the Crown Jewel pay-per-view in Saudi Arabia on October 31st.
The wrestling company made headlines worldwide last week with both former UFC heavyweight champion and heavyweight boxing king Fury.
Velasquez retired from the UFC before signing a long-term agreement with the WWE for his debut.
Lesnar confronted a ghost from his past moments after capturing the WWE title from Kofi Kingston on Smackown last Friday.
The Beast had launched a violent attack on Rey Mysterio and his son Dominick days earlier on Raw.
But while celebrating his championship win on Friday, he was suddenly interrupted by the "Master of the 619" and Velasquez – the man who defeated him in 2010 for the UFC heavyweight belt.
The former octagonal king, a friend of Mysterio, then ran into the ring to beat Lesnar to take revenge on behalf of his friend.
The UFC legend was not the only one to be named as a megastar that made its WWE debut with boxing's Fury, who also decided to officially enter the ring in a fight against Strowman.
"I just want to say how honored I am to be involved in something like that," Fury said. "I'm a fan for the whole life of the WWE and I've always wanted to do something like that.
"After seeing Braun Strowman, I really know why he has the nickname of Monster Among Men, but being the unbeaten champion of linear boxing, I fear no man.
"I have run into 30 professional competitions and when I go to Saudi Arabia to fight Braun Strowman I will not be unbeaten because I will knock him out.
"Talk about how good his hands are but he's joking with a guy who has the best hands in boxing."
