**DSA!Inverted Battle: The Fallen World** (Also known as TSA!FallenPaintedGround) is a Fell version of Inverted Battle: Underground Fate. No new areas are present, but there are several major changes in the main characters.

## Characters

For the characters, see TSU! (Team Switch UP!) Inverted Battle: Underground Fate § Characters.

## Major Character Changes

Frisk (Avery) is more scared of the Underground (similar to Horrortale's Aliza) than in any of the other IBUF AU's.

Flowey (Triton) is the same as normal Underfell Flowey, except he is left at 1 HP after being attacked by the Ruined Arena monsters.

Toriel (Chara M.) is more caring and less scary than Underfell Toriel, but still acts like Underfell Toriel.

Chara M. will also leave the Ruined Arena if you save her and join you on your journey, supporting you in battles.

Sans (UltraGalladivor) and Papyrus (Josh) are the only other kind monsters left in the Underground, and help the human all the way to Asgore (Caleb). Papyrus and Sans follow and help the human most of the time. Sans does not help in battle (for fear of being hit and dying). Papyrus helps in battle by healing 10 HP every turn (If all nice things were said during his date) but won't help during the Undyne (Kendall) fight since he is scared of Undyne (Kendall). Toriel (Chara M.) however WILL heal you during that battle.

Sans has protected Papyrus his whole life (Same for normal IBUF).

Neither of the brothers fight the human except in Expert Mode, and Sans only in Expert Genocide (It's impossible to kill him unfortunately due to Josh evacuating, Matthew will eventually leave the battle to join him.) If Josh however, was found and killed... You won't have a very good time...

Undyne (Kendall) is very aggressive and involves a lot of running, until reaching Fire Cove.

Instead of Alphys (Ashlynn) and Undyne (Kendall), Sans and Undyne are dated. (IBUF is the Only other AU to do so)

Alphys (Ashlynn) will fight the human 3 times, being more aggressive and having a hard battle.

Mettaton (Hunter) will fight the human 2 times in Pacifist/Neutral and 4 times in Genocide (twice in his "Final Forms"). He is very hard to get past, and his Final Forms (Hunter Ultra and Hunter Ultimate NEO) do not die in one shot.

Asgore (Caleb) has accidentally killed monsters, causing the violence in the Underground, and the general problems in this world. Asgore is at LV 10, making the fight harder than normal. He does have a Genocide fight, unlike normal Undertale.

Asriel (Rei) isn't much different from his IBUF counterpart, except for the clothing and having attacks (similar to Asriel the Ultimate God of Hyperdeath)

Ari (Will be changed to Felicity soon) is also not very different from their IBUF counterpart, except she has different dialogue for pacifist and genocide routes (as she appears in both)
