Was talking in discord, and speaking of new OC's and somehow this spawned.  You can thank Originalsparkstar and Lunazul3000 for this and some scenes or just cheering it on.

"Fear me"

Sans looked down, standing not even reaching his knees was a tiny baby bones in a reaper costume with a fake scythe and wings.

"Cute costume kid," Sans said patting the kids skull, then dropped dead for patting death.

Reaper pouted, no one ever took him serious.

"Brother!" Grim said rushing over.

"Pappy!" Reaper squeaked "The meany patted me and ran away!" he sad pointing to the dust.

"Ah, yes... runaway..." Grim said coughing, why... why did his sibling be created as a child. They were Death and poor Sans didn't even understand what dusting was yet.

"Oh... my stars...." Geno said, staring at the tiny figure that had invaded the save screen.

"Fear me!" Reaper squeaked.

It was like facing papyrus as a kid again.

Which is why Reaper was startled to be pulled into a cuddle, and the person not running away.

"Are we friends?" Reaper asked excited wings fluffing.

"You know what.. sure."

------

"Geny do you know why people run away from me?" Reaper asks Geno.

"What do you mean run away kiddo?" Geno asks the tiny death god.

"Well, when they touch me they just disappear. You and Pappy are the only ones who don't. Am I really that scary?" Reaper asks.

"Oh kiddo..." Geno says sadly.

Extra:

"Wait.. what's going on?" Grim said very confused, and very very worried.

"Some wacky thing caused a massed merging with there OC's, kidnapping some people from other multiverses or Omniverses," Reaper chirped.

"Have you been eating Blues Taco's again?" Grim asked, people sometimes saw things after eating them.

"Nope, but I want to tell you about the kid in the mask and the person another older Reaper seduced!" Reaper said excitedly, Grim squawked at the word seduced.

"Your grounded!"

"But.. I wanna tell you about the OC's," Reaper whined.

"Nah nah nah.. can't hear you!"
