Suggested by Sonic This fight is fairly close because while Mephisto has appeared a whole lot more than Nightmare, he’s not typically much of a fighter. He prefers to stay in the background but when necessary he can mix it up. Nightmare’s dream abilities will do absolutely nothing here so he will have to rely on his energy projection which is solid but I just don’t think it will really do much of anything here. Mephisto then wins in raw power. Mephisto wins.
