Undertale Last breath Created by ZerJox Inspired by Toby fox. Last breath was a popular undertale fangame. People made videos,New phases,etc,  The main focus is the cannon last breath Fan Game. It has 3 phases I think that phase 1 is the hardest. W.D Gaster helped sans and gave him more knowledge through out the genocide route. He informed Sans that it wasnt the first genocide route they were in. G even taught sans orange attacks I would rate phase 1 difficulty a 9.5-10. Why? Usually when anybody tries the fight for the first time you usually get shredded on the first attack easily. The first orange attack Sans introduced you can do a little cool trick go to the middle of the box and move side to side so the orange bones wont damage you and the other attacks wont either. Final Attack pretty difficult definitely a hard final attack at the end of the final attack you wont have a lot of health so sans rick rolls you and throws a gaster blaster spam. And as we all know he slams you across the room as his last attack of phase 1 you cant die to it thats the good thing :) Then after you slash sans and give him a massive wound he starts talking about resets and asking you why you did all these terrible routes. W.D Gaster doesnt allow Sans death this time tho. You get to see sans health and he has like 000.1 health  You get to Phase 2 with all items back and full Health. Sans has the ability of flip screen. Still uses orange bones. Insanely Hard I still think phase 1 remains the hardest tho. On phase 2 he moves the box around making it more difficult to avoid his attacks and the final attack uses a lot of that. Sans eventually gets tired of fighting                                                                     Picture of Last breath Phase 2:

Phase 3 Is the final One phase 3 starts with a long speech from Sans and after that the music starts to intensify while also breaking the buttons such as: Fight,Item,Mercy,Act.  After all thats done you see W.D Gaster Behind Sans. Sans also got a crack on his head coming down to one of his eyes. The Start of phase 3 is insanity Color bones everywhere blasters all around the box its to much for anybodys brain. At one point you get to see W.D gaster and he helps with his creepy hands shooting wingdings at you.                                                    Picture of  Last breath phase 3:        Credit to merg for the image

The 3rd phase ends with gaster blaster spam. You wound Sans once again and he fades away. While heading to king asgore Flowey the flower ends up catching you with his vines.King Asgore finishes you off with his trident and broke the barrier to the surface. The end.
