"ok you've been saying the word 'seven' for 5 hours straight."
– Fisk, while talking to Undine


BT!Elatrednu is an AU that follows roughly the same plot as UNDERTALE, but with a more comedic theme to it. It revolves around Fisk falling into and exploring the underground, but also trying to find a way back to the surface. This AU is worked on often with new parts of the comic coming out often.

Characters[]

Fisk[]

Fisk is the protagonist of BT!Elatrednu. He's usually pretty rude to most monsters for no reason, most likely because of the random stuff they do, and likes to do basically whatever he feels like doing. He likes to explore and look around the underground, but also kind of wants to go home and play Fortnite.

Flowbee[]

Flowbee is the "villain" of BT!Elatrednu. Oddly though, as shown in his appearances in BT!Elatrednu, it doesn't appear as though he wants to harm Fisk, as when he accidentally kills Fisk, he runs away screaming.

Toral[]

Toral is a friendly monster who takes care of Fisk while he's in the Leftovers. However she does seem to have a darker side. When Fisk decides to leave the Leftovers, Toral gets so angry she accidentally kills him, but doesn't seem to notice or care at all, instead yelling at him for changing the subject.

Sarns[]

Sarns is an odd character in BT!Elatrednu. Unlike Sans, he usually isn't shown to be lazy or interested in puns. This may just be due to his short screentime in the series though, only being in 3 parts.

Paperus[]

Paperus is a goofy and silly monster, just like Classic Papyrus. He will usually believe Sarns no matter what he says. This is shown when Fisk is standing right in front of Paperus, but believes Sarns when he tells him it's just a lamp.

Undine[]

Undine is a warrior who was sent to kill Fisk and take his HEART. Unlike Classic Undyne, she doesn't have an eyepatch, but does have 2 dot eyes. She may also have some kind of problem with her brain, as she often does weird things, like forgetting she was sent to kill Fisk or just saying "seven" for 5 hours straight. Undine is one of the more weirder characters in BT!Elatrednu.

Locations[]

All locations in BT!Elatrednu are the almost exact same as in UNDERTALE, just with alternate names.

  • Leftovers - The Ruins
  • Toral's House & Toral's Basement - Toriel's House and Basement
  • Sarns & Paperus's Shed & House - Sans & Papyrus's Shed & House

Trivia[]

  • Early into BT!Elatrednu, Fisk used to be a lot more similar to Classic Frisk. This is easy to tell because of his eyes usually being shut and seemingly non-existant personality.
  • BT!Elatrednu used to just be called "Elatrednu".
    • This was changed because "Elatrednu" wouldn't fit as a good AU name as it's just Undertale backwards.
  • Sarns was the first character designed for BT!Elatrednu.
