Just reuploading this from deviantART~
I'm starting to like this site a lot, and dA has gone a bit overboard for me.

dA description:

"So
Yes, this is Purple Guy in cat form because I suck.
And this was also kinda expression/tears practice because I just... felt like it. It looks good, I think.
ANYWAY
this is my favorite FNaF theory so far. It just makes me happy.

Spoilers for FNaF 4, I guess?

It's heavily implied that the main character AKA kid you play in FNaF 4 is Purple Guy's son (I'm not sure where it's implied, it just... is. I dunno. Don't ask me. Ask the people who said it was.) and the kids who ended up being the reason for his death all had the main 4 animatronics' masks on. So what I'm thinking is that Purple Guy wasn't very happy that his little son died, especially since his brother was responsible, and killed them all. As for the other kids that he killed (apparently he killed 10/11 kids total?) maybe something set him off or he just enjoyed it. I DUNNO!
But those kids were kinda fucking dicks, so now I kinda like Purple Guy?? I dunno. He was justified in killing them, if he really did.

DON'T TRY TO CONVINCE ME THAT THIS THEORY IS WRONG BECAUSE I CAME TO THIS CONCLUSION MYSELF AND I LOVE THIS THEORY DON'T CRUSH MY DREAMS DAMMIT

AND YES THE TITLE IS FROM A SONG BECAUSE I'M TØP TRASH OKAY?"
