Lucas is an unparalleled fighter who can know his opponent's weakness before the battle even begins. He possesses an unbreakable demon sword that can deflect anything. His power is at 100, and nothing inside or outside of reality can damage him. Lucas also has minions that are beyond and more powerful than omnipotent. He can exist outside of reality and reset to the point where he's full again if he dies. Meanwhile, Rison, the Demon Prince, has a lower tier rating and lower stats in terms of power, guard, speed, and skill. Although he has magical abilities and passive abilities that can increase his damage output and endurance, it's not enough to defeat a god-like figure like Lucas. Additionally, Rison's entry prompt already shows that he's scared of Lucas just by appearing when blood pours from the sky. Overall, Lucas' overwhelming strength and abilities make him the clear winner in this battle.
