== About the Au ==
This Au is a merge of the sonic and undertale games. I tried to merge each character who had the most in common with another. If you have any other better ideas for some of these characters let me know in the comments.
== Characters ==
Frisk- Frisk has been swapped with Emerl. Emerl can learn attacks from other characters and can make them more powerful using determination.
Flowey- In flower form he is eggman, in asriel form he is ovi kintobor, in omega form he is the death egg, in his god of hyperdeath form he is the death egg robot from sonic forces, and in his angel of death form he is in the final phase of the death egg robot from sonic forces. You never actually see Eggman because he sends a remote controlled egg robo to cause trouble and talk through.
