Fatal Error is so underrated and underused. As a fandom we kinda collectively view him as the weird cousin in the 'Error family', but his moveset and how it functions says a lot as to what outcodes, universes, and the multiverse as a whole is made of. Fatal is able to copy and paste codes, be sentient or not. If it weren't for the fact that Fatal mostly keeps to himself, we'd be a frighteningly powerful being. He could mass-produce an army of an all-powerful deity. He could mass-produce weapons of destruction and chaos. He could mass-produce healing items and food or stuff with other magical properties. As long as it's made of code, he can abuse it. He can even stitch code together to make something new. Fatal technically could take pieces of code of a similar type and make them into something even more potent. Collect a bunch of healing item code and stitch them together, you get something that could heal an army, like some items in DR heal multiple people. Fatal does actually do something akin to this by going around and copying Swap Sans code to make himself a new Papyrus, named Patch. He can even corrupt code too, to the point one can barely function as they were before, as seen with... *checks notes* ............. *deep inhale* Lost Flicker Gans Bans Ean Missing!File Bob Sans. It also brings up as to what happens if he tries to copy something or someone not made of code, like Nightmare, who's not from the UTMV technically anyway. Does it fail? Fatal isn't really known for his fighting capability, but he's really good at the act of surprise. Outside of 0.7, it is canon in his own comic that he's able to capture and kill a Cross. Like, just imagine a story with me. Someone somewhere manages to get Fatal to join their cause, whether through promises or blackmail. They suddenly have access to an awesome Rogue, cloning ability for free, and infinite supplies. Copies also retain all the memories a person would have at the time of them being copied, and no one can tell if they are one or not. You don't even need to "bring a hostage back alive" for interrogation when all you need is their copy. And the cherry on top, leaving Fatal to his own devices will let him stitch a bunch of code together to make a Frankenstein-flavoured whatever, likely new to the multiverse using old pieces, which could be useful or the downfall of whoever Fatal is working with. The only thing Fatal is really missing to become the danger he could be is motivation. Even then, there was always one special someone he always cared about...
