so on some website I don't remember what it's called they came out with a fan made version of storyshift chara's boss fight and it was so cool!

Storyshift chara:...hi...why?...why did you do it? why did you kill everyone I love? even dad's gone missing, and he's too nice to ever hurt anybody. what is this feeling?...wait. I remember this feeling. it's hatred. hatred for the person that came so far just to destroy my family. I used to be like you. filled with hatred. but I changed. or at least I thought I did. but I guess...I guess I was wrong. because...when I found asriel's dust, I...something broke, deep inside of me. but I waited. I waited to see what you'd do. you butcherd them all. that's when I realized. I haven't changed. I just lied to myself. I still hate humanity. you...you've reminded me why. I know why you killed rthem now. because it's our nature. all we do is hurt. we enjoy hurting others. don't you? I thought I was different. I thought I could change. I guess there's no point running from what you really are. they used to call me a demon. it's funny, because...I'm going to send you to hell where you belong. I'm determined to make you suffer. get ready to die.

yup that's all the game did XD but I still think it's cool because we're still frisk but we just killed everyone chara loved so yeah chara is gonna kick my ass....not looking forward to that......but it's what we get for killing everyone....

and this is what chara will say if you beat them!

and this is the song that plays when you fight chara!
