Suddenly everything is dark and everyone around you is gone. Only you and what small monster is in the place of every monster you have become friends with on your journey, Flowey is gone. (Now for Asriel's point of view. Just flat out. Too much Frisk,Sans and Papyrus. More of the rest!)
You giggle slightly for a moment, you speak to the human and say.
"Finally. I was so tired of being a flower."
You turn around to greet them, lifting your head with a smile. You say to the human.
"Howdy! Chara, are you there? It's me, your best friend."
Suddenly you change form and everything flashes instantly. You say to them in a loud booming voice.
"ASRIEL DREEMUR!"
Asriel thinks to himself. This will be quick and easy. everything around him starts changing into a constant mass of deteriorating reality. Nothing is as it seems. Colorful and formless, his shadow is moving with his form, making temporary clones of himself that die off the instant they appear.
He summons giant stars at the human, their soul dodges every single one thrown at them. Asriel charges his attack.
SHOCKER BREAKER he notices the human is getting something to eat out to heal themselves. He says with a smug grin at the human, feeling nothing at all.
"You know...I don't care about destroying this world anymore."
He shakes his head while talking, having his arms up. He throws an attack at the human. Mild bolts of energy that get intense. The human dodges every move.
Asriel calls on CHAOS SABER He thinks to himself. Their fight for freeing everyone is useless....I have absorbed everyones souls! I am a god now and their battle with me is meaningless!
He speaks to them with another grin.
"After I defeat you and gain total control over this timeline..."
His expression gets intense for a moment and he says to them.
"I just want to reset everything."
The Chaos Sabers appear and he starts attacking the human, they dodge his every move once again, while attacking, Asriel disappears for a moment and reappears. He speaks again afterwards with another smug expression, to a cruel one.
"All your progress...Everyone's memories. I'll bring them back to zero!"
Asriel sends another lighting bolt attack, they dodge them. He ignores it.
Asriel readies. STAR BLAZING!
He speaks more.
"Then we can do everything ALL over again."
Asriel is very sure of himself, grinning about it. Asriel shots giant stars at the human again. The Human dodges his attacks again.
