The Lion's Den also attracted many top fighters from outside to seek help in their training, including UFC Heavyweight Champion Mark Coleman, UFC 6 tournament Champion Oleg Taktarov, and UFC Heavyweight Champion Maurice Smith. After losing at UFC 5, Taktarov went to live and train with the Lion's Den, and subsequently went on to win the UFC 6 tournament. Maurice Smith, a world class kickboxer, offered to help the Lion's Den with their striking in exchange for help with his submission and ground skills. While training with the Lion's Den, Maurice Smith defeated Mark Coleman to win the UFC Heavyweight Championship, and became the first striker to survive the attack of a world class wrestler. Smith later joined forces with Lion's Den fighter Frank Shamrock to form their own team, called The Alliance. Coleman, after losing two fights in a row to Lion's Den fighters, went to train with the Lion's Den and was coached and cornered by Ken Shamrock at UFC 18.
