The cracks on his body and holes in his hands are the scars left. - A goopster, a jokester, and a good dadster. - He has loved Grillby for nearly three hundred years, but he has always been rejected :C - He uses sophisticated words just to show he's smart. - A stupid genius. - °Slaps egg° this boy can fit so much trauma.

Believes in the good Angel of the Delta Rune. - He fought on the front lines of the Great War. There his soul was damaged and now it's difficult for him to speak. - Uses sign language.

Name: UW!Papyrus (UnderWifi) * Age: 20 * Height: 6'1'' (1,85m) * Birthday: 5 June (2024) * Stats: Lv1: HP 680, AT 20, DF 20 * Abilities: Bone attack, Blue attack (green), Telekinetic power (+can fly), Gaster blaster

UnderWifi Prologue: 201X Long ago, two races ruled over Earth: HUMANS and MONSTERS. Humans feared them because of their advanced technology and magical power. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the Monsters in a game and destroyed it. Humans thought they were finally rid of them; however, a certain person had downloaded the game program before its destruction. Over the centuries the existence of Monsters has faded from memory, only legends about them remain but they are still alive and want revenge. 401X Four thousand years later, the game was reactivated and connected to WiFi. This helped open a "door" for humans to UnderWifi if they played the forgotten game. After the arrival of the first human Chara, hope for peace between the two races was once again considered. She had become friends with the young prince Asriel and was adopted by the royal family. The new royal scientist aimed to find a solution to free the Monsters without using human souls. On the other hand, the judge did not share the same optimism and had a deep hatred towards humans. He decided to collect himself the 7 human souls necessary for their liberation. No monster is aware of these actions. Any other humans who played the forgotten game never returned. 402X Ten years later, a young human named Frisk played the game and was in turn digitized. But unlike the other humans who “visited” UnderWifi, her soul was a soul of determination. It was impossible to kill her and she had complete control of the game.

This started just as an idea of what if Slash and Onyx met if they were both children. I ended up canonizing Onyx to start his life as a child. I didn't feel comfortable, it was too weird that Onyx had an adult body and the mind of a child. Anyway, I threw some Onyx lore as well. Yes, Onyx was a ball of innocence and naivety that still doesn't understand the concept of danger yet in his early days of existence.

Just as an idea, yes, only Onyx speaks, G is the one who speaks at the end.

So what was/is Silver's original au like? I've seen you post stuff alluding to Slash's og au being some kind of wartale-like thing, but what about Silver? How's he different from a classic!sans?

Slash and Silver are both brothers. Silver is big brother.

Slash was a soldier in his AU and Silver was working with science from what I recall.

They were both created by UW!Gaster, G

They both come from Underwar AU created by @itsxroxannex . You can visit her blog if you want to know more about the two of them.
