(NOTE:This is not a battle! This is an animation or test for a cutscene. But if you want me to make this into a battle. Ask me yes or no in the comments.
In an alternate Universe what if Sonic took Sans place? Or what if Sans was killed and Sonic was the last one alive? This is my first time using a Undertale AU thing. Because I like Sonic,I decided to put him into Undertale. Undertale belongs to Toby Fox Sonic belongs to SEGA I own the AU of this. (There will be more)
