Destructive & Mischievous Bean

Fusion!

Error and Blue had been together in the antivoid when Ink threw a device through a portal. "Error, What's that?" Asked Blue, pointing at the device. "I don't know." Said Error. They walked over and noticed it was ticking. "Error! I think it's a bomb!" Yelped Blue. "What?!" Error exclaimed. Before they could do anything the thing exploded with a loud bang and burst of multicolored paint.

"Uggh," said Error. "Did it explode?" Asked Blue. Error noticed he had felt his mouth move and speak, but he wasn't speaking. "Blue?" Asked Error. "Error, wait! Are we in the same body?" Asked Blue. Error summoned a portal mirror. They had Blue's white bones, Error's tears but lighter blue, they had black sockets, one baby blue eye light and one one blue with a yellow ring, and were around an average height. "How in the antivoid did this happen?" Thought Error. "I don't know, Error." Thought Blue. "Wait, can we hear each other's thoughts?" Asked Blue mentally. "Well, there goes any form of privacy." Thought Error. "I heard that you know." Blue thought back. "I'm going to check us." Said Error. He pulled out their soul. It had hairline cracks, but was mostly intact. Pale blue strings loosely wrapped the soul. It had the traits of patience, caring, bravery, loyalty, justice, and mischief.

"So, we seem to be stuck like this." Said Error. "We need to call ourselves something, then figure out what to do." Said Blue. "How about Fusion? We are a fusion of each other." Suggested Error. "That sounds good." Said Blue, "Ohh, and we can call each other something. You can be Compute and I'll be File!" "Okay." Agreed Error.

"So, Fate can't force us to destroy, so we don't have to do that." Said Compute. "Yeah, but we can't go to underswap as they believe it's me." Said File. They considered it for a moment. "I know! We could pull pranks!" Said File. "That does sound interesting..." said Compute. They started their planning.

A/N: this is based off an idea called "Cinnamon and Beans" from Firehedgehog 's idea factory.
To clarify, Fusion is their name as a unit, Compute is Error, and File is Blue.
Bold = Error before fusion
Underlined = Fusion(Compute or File) speaking aloud
Italics = Fusion (Compute or File) thinking or mentally talking
