Guts vs Nightmare

Not only is it absurd to say Guts wins because he fights people stronger than him every day, he never really fought and defeated something of Nightmare's calibur.

Nightmare is far more powerful than beings such as Cervantes who make giant thunder storms and cause massive earthquakes, everyone in the series is capably of summoning lightning bolts onto themselves to empower them but also move at comparable speeds to the lightning.

On the higher end of things Nightmare scales to would be Abyss, who covered the entire planet in clouds and boiled the very earth itself and may have even caused a solar eclipse with how the sun appears to be blacked out. He may even scale higher than that, as Inferno can create the realm of Chaos which if official art is correct, is able to contain entire nebulae akin to the Homunculus Nebulae, that would be akin to creatin an entire small galaxy. It's possibly not even the only case of it as Chaos in SC3 also contains a gas giant and what could even be an entire cosmos from within.

TL;DR: they put a character far more powerful than Femto (the being who easily dealt Guts the worst day of his life) and said he could win.
