Nightmares POV
Error has been really off lately...after the incident  where we all thought he had died, he had changed not physically but emotionally and mentally...he seemed more alert and vigilant...he wouldn't rest and he would ALWAYS make sure we were ok...it's like something had got him paranoid..yet every time one of us asked why he was acting so strange he would only walk away completely ignoring the question....what happened to him while he was out?

Errors POV
Ugh! I hate it when the gang thinks I'm acting weird I'm only taking care of them! I don't want them getting hurt or even worse..like MY AU had. I can't lose the people I care about again...especially not my MATE. I won't let fate and her cold bitter hands snatch them away. I was powerless before, since I was only another sans, another of her toys, another pawns but NOT anymore I'm Errorsans! I'm not like the rest of the sans because I'm the GOD of destruction and I won't let anything happen to my friends and mate. I will never leave them not even if it kills me!

Narrators POV
Error had been overprotective of the gang for 3 weeks now but the gang would always ignore it, but that all changed when one day Error got severely hurt...nightmare and his gang had been in underverse collecting the negativity when Ink arrived...he seemed weird his eyes weren't the the usual starshaped eyes and colorful splotch but both eyes were red and black pupil perfectly round and in the center he seemed inraged...he charged towards error and errors eyes also changed but his changed into a navy blue and black pupils while his teeth sharpened and he had a scar right along his face...these were the features that error used to have when he was still in his AU but no one knew it. As ink charged towards error, error only smirked and summoned 2 thin long katanas and stood still..he waited until ink was close enough then he teleported behind him he did a double kick flip causing ink to stumble on the ground...he had two long slices on his body but ink got up and kept going soon Error and ink were both injured Error had scars and a gash along his skull all the way to his ribs and ink had bruises with thin slices all over his body. Errors and inks eyes soon went back to normal and they both collapsed..Error was gushing blood but it wasn't visible while ink was bleeding rapidly and was staining the white pearly snow. Nightmare and his gang were bewildered that both gods went into...overdrive

When a powerful being or god goes into war mode or destruction mode it's when they use their powers to eliminate or terminate something for good no matter the power it is the power will still become deadly
