"Generation loss" refers to the degradation of quality that occurs over time as visual or audio media is reproduced. Each copy of a source is a new "generation", and every time a new copy is made, information is lost. Every time you try to remember, you forget just a little more. #DELTARUNE

FRIEND slander will continue until it becomes relevant. #DELTARUNE #DELTARUNEChapter5 #DELTARUNESpoilers #KindaSorta
The "Potential Man" meme, with Friend from Deltarune.

"Meet Potential Friend!"
"Pink and yellow! It's obviously the Tail of Hell! Mi-Ke cats are associated with luck! It's Mike and also the caller and also the antagonist and- Just wait until it appears in Chapter 5. The file names prove it's related to Gaster! Its connection to Cat Petterz is definitely important."

"0 lines, 0 plot relevance, 7 chapters doing nothing."

"Give me liberty, give me fire, give me fanart or I retire."

"Make my debut in a chapter heavily associated with my colors? No. Appear as a random easter egg again and have my aura taken by a weird bird! Yes!

"If" and "when" but never "is"

NEW OC FOR ART FIGHT! It calls itself Stranger. It's a moth...thing..? Maybe? Probably. Its body doesn't reflect light, but that's probably normal. I'm not sure if the hat's part of its body or not, to be honest. artfight.net/character/88... #ArtFight2026

Working on refs for Art Fight. Meet one of my oldest OCs, Aeris! What is he? It's complicated. What are her pronouns? Xey don't know, just use whatever. This is their "default" form, but fey're a shapeshifter so its appearance isn't very consistent. #ArtFight2026 #DigitalArt #OCArt
