some of my favorite trends in Undertale fanart:
- papyrus’ jaw sticking out at odd angles when he’s yelling
- mettaton hugging people by wrapping his noodle arms around them like 34 times
- sans with a definite belly, no explanation given
- frisk using asl (and all the monsters understanding it)
- that post-pacifist au where frisk keeps flowey in a flowerpot and he’s just a whiny little shit
- toriel with a slightly dragon-like appearance
- sans hiding things in his jacket
- papyrus and toriel picking sans up when they hug him
- papyrus being amazing at helping people thru panic attacks
- undyne with impossibly long flowing hair
- undyne’s “hair” actually being a fin
- sans with a gap in his front teeth
- alphys’ pudgy little tail
- mettaton/napstablook bonding
- mettaton/frisk bonding
- chara as the provider of the game’s flavor text
- sans treating the gasterblasters like pets
- sans instantly falling asleep in weird places (usually papyrus’ arms)
- god of hyperdeath = asriel’s totally original OC do not steal
- asgore hastily naming asriel by mashing together his and toriel’s names
- gaster being really sweet and gentlemanly before The Accident
