The idea was originally found in A_Bored_Reader Undertale ideas for stories that hit me like the brick called Reborn! I asked permission to use it. Read the original if you're interested, but it contains quite a few spoilers for this story.

[Warnings: Fight, wounds, puppet master, bad intentions and manipulation.
Anyone would be interested in a comic version of the story enough to provide financial support for its realization?]
Goth destroyed the positive arrows aimed at him with light movements while weaving strings through the sky. Dream, realizing the futility of the arrows, switched to two blades and cut across the battlefield, targeting him.
– Not so fast! – Killer blocked Dream path with a wide grin and his knife. Deep down, Dream felt a little relieved that he could fight someone else. The blade clicked loudly as they clashed, but the noise of war drowned out the metal's song.

– What a protector are you – Killer teasingly kicked him in the knee. Dream hissed, but despite the pain, his golden eyes shining with magic as he jumped out of the way of the red blades, which Killer tried to put in his back.
– For the sake of the Multiverse, get out of my way! – Dream resolutely jumped at him with the other blade aimed at his throat.
– You sound like Ink – Killer rolled his eyes, blocking Dream attack and cutting his hand with a knife twist.
– Ink wants the best for everyone – Dream stabbed him in the side disapprovingly.
– Do you really believe that? – Killer laughed and kicked him in the chest, making him step back.
– What do you know? – Dream overcame the pain and aimed for his opponent's leg, who teleported away and attacked him in the back.

– Do you really want the death of your own child and his love? – Killer ignored his question with a wide grin, Dream turned to the side, blocked the blade pointed at him while faced Killer.
– I don't want anyone to die, but you guys leave no other options to me – Dream accusingly tried to kick him.
– It's easier to blame someone else than to admit your mistake – Killer chuckled, jumping to the side out of the way of the attack, sending red blades at him.
