- Sans Before Fighting Corrupt!Multiverse!Sans

Sans From The Original Universe, Undertale! After Sans Got Pulled From The Original Universe By Error, Error Told Sans That He Had A very Important Task To Do, Kill Corrupt!Multiverse!Sans, So Sans Goes On A Journey Looking For Every Au Sans he Can, To Finally Go On A Final Showdown With Cm!Sans(Corrupt!Multiverse!Sans)

Important Facts:

Sans really Doesn't Have A Serious Attitude, Making Fun of Every Enemy he has To Face, Like Always

Papyrus Died, but he Doesn't care As he Knows It's All Gonna Reset, So Why care? (I tried Doing This Sans As Canon As Possible)

Sans is More powerful Now, Since Sans Went To the Mainframe When Looking at An Opening to it, Mistakenly Put There By 404, And Had a Talk With 404 Giving 404 A new View, But Not Enough To Leave The Mainframe

Sans Has Fought The Most Powerful Sanses In The Multiverse, The Likes of error500 And Just404 (With Some Help of Course, And Losing A few Times but At The End, They Convinced Them To Join Them In the quest)
