The Tale of other worlds. (an Undertale X RWBY Crossover)

Everything was saved. The Human, Frisk, managed to get through to Asriel and they managed to break the Barrier seperating the Monsters from the rest of the world.

It was a good ending. A Happy ending.

Until everything fell appart.

No sooner have the Monsters left the underground did the world around them glitch and break. In an effort to hopefully prevent the worlds demise did Frisk try to reload their last save. Yet with the world breaking, their save file got corrupted and the attempted reload made everything go white.

And once it all got back to normal did they find themselve in a city that was unkown to them. One that was filled with Humans as how she knows them as well as some that have animal parts on them.

But they were alone. Not a single Monster was with them. And even their guide through the underground, Chara, was absent. Being alone in a world unknown to them there is only one thing they can do.

They are going to find their friends, and they are Determined to bring everyone back home.

And maybe they can make some new friends on the way.

(Please note that there can be spoilers for both Undertale and RWBY. Also a few things that come here can be more considered headcannon rather than actual cannon, either due to missing context or personal preference.)
