Changing everything now since I like to. Been getting inspiration from a lot of sources and I decided to make my own Undertale Au with my best friend. It's still in development and I don't know know if I'll make it public but I might make a story on it. It's called Legendtale and my cover photo is the Sans is the Au nicknamed Blackreach or Legend. Now yes he's very different from a regular sans but still a skeleton and there's a reason for this. You see the au code is glitched (to which would probably piss off Error so I wouldn't be surprised), changing some of the characters designs, giving them animal features like Blackreach who's a hedgehog dragon hybrid thing I made up years back. The gender of some characters have changed too but the personalities are still the same. I just thought it would be very unique about the Au. 

As I've said it's in a development stage and could be acquired to changes. I also want Blackreach to be a very strong sans like Error 404 but I'm not sure if others want that so I'll keep it unknown for now. I have give him powers being the usual bones and blasters but he also has fire powers, different states or forms, a bad state like a Fallen Sans and his third magic eye is a one use medusa I pulled from no where cause why the hell not. Also gave him a role I haven't seen yet and that's Multiverse Judge. 

If I do a book I'll probably write pages for each character or something. I'll get inspiration. Me and my friend want this to be the strongest Au but I dont think it can beat the canon strongest so me and my friend will keep it to ourselves for now.
