AU by me. A note: O2!Sans, despite being in the background for all of these Phases, doesn't actually help fight. (NOTE: All sprites are based on Sans' height being 5'. If the character is really large / really small, they might be rescaled.) Oh, you thought that The Deadly Skeleton of Terror would be Phase 69? Too bad, the idea's too simple for that! ...I just realized Red Megalovania is coincidentally Phase 47 in both O2 Supply and Un-Ending Oxygen lol Error Sprite by Midear Mari sprite from OMORI Sonic sprite by Pixelbit0 Swap!Papyrus sprite by Yuttari Underfell!Sans sprite by ???
