2. Brock Lesnar
Brock Lesnar is a name that could bring the Rizin promotion to another level. Lesnar is still one of the biggest draws in the sport because of his starpower. He is a WWE star that brings his championship level wrestling and athleticism to a new level.
There are quite a bit of big name fighters for Lesnar to compete against and Shane Carwin has even flirted with the idea of coming to Rizin. Heath Herring is another opponent that Lesnar has faced who is now signed under the Rizin promotion.
Of course Rizin would have to fork out quite a bit of cash to be able to get Lesnar to sign. He makes quite a bit of money elsewhere and will only settle for a big price. He only signed a 1-fight contract with the UFC and he would be eligible to fight in Rizin regardless of his suspension.
