Okay, I’ll type everything out because my handwriting isn’t the best (especially on a whiteboard)

On the left I have the Games and Books (Silver Eyes) Canon, and on the right I have the Movie Canon. Left I put Henry Emily being the father of Sammy, and separated Charlie and Charlotte, because they’re truly two different characters in the different canons. Then I have William Afton as the father of Mike Afton, Crying Child, and Elizabeth. 

On the Right side of the board, I have William Afton being the Father of Vanessa and TBD (this will make sense later). Then, I have Henry Schmidt (placeholder name because we don’t have any canon names) being the Father of Mike Schmidt, Garrett, and Abby. 

I have color coded each character to who parallels who in the different canons, and the bottom text explains that. 

Yellow is Elizabeth and Abby “Elizabeth and Abby is easy, it’s literally spelled out.” This is about how Abby rearranged spells out Baby. Most people consider this to be the first and totally concrete parallel. 

Orange is CC and TBD. “It’s just a theory, but it connects the dots.” I believe there is a Crying Child in the movies, we just haven’t met him yet. The movies having a Crying Child equivalent could flesh out Vanessa and William’s characters at the same time. 
     
Red is Mike Afton and Vanessa. “Mike Afton and Vanessa both do William’s dirty work, but they only do it because they caused CC’s/TBD’s death.” I am suggesting that Vanessa is the Mike Afton of the movies. Yes, there is more theorized nuance to Mike’s character in the games, but I suspect the writers of the Movie wouldn’t include ALL of that lore for something that’s supposed to be a bit more simplified and generalized for a wider audience. 
     
Black is Charlie (Silver Eyes) and Mike Schmidt. “In Silver Eyes, Charlie dreams about her dead brother who was taken by William Afton. In the movie, Mike Schmidt does the same thing.” Yes, I understand Charlie is the one that died and she’s a robot blah blah blah, I don’t expect the movie to go into that, so I’m relying on The Silver Eyes only. 
     
Blue is Sammy and Charlotte combined, and Garrett. “Garrett is both Sammy and Charlotte. He is taken by William Afton in both, and it’s his first, car related, personal kill. Garrett and Charlotte both possess the puppet now. Garrett may be the one saying “it’s me” to Mike Schmidt.” This may seem wrong for many reasons. First, in the later books, it’s actually Charlie that died, not Sammy. But strictly in The Silver Eyes (the book they pulled from the most) the plot line is Charlie trying to find out what happened to her brother, so that’s why I used it. Second, we don’t know if Garrett’s death was truly personal or not, but we do know that William Afton drove to Nebraska, which may be at least one state over from where Freddy’s is. Why would he do that if it wasn’t for a personal reason? And lastly, the only evidence I have for Garrett being the puppet is that the “It’s Me” being Golden Freddy doesn’t make sense to me for the movie canon. If Garrett is in Golden Freddy, was he just randomly stuffed in there alongside the blonde kid? That doesn’t make much sense narratively. But Garrett, a very important piece in Mike’s life, that’s also a very important piece to a future character, and the ghost kids, makes much more sense narrative wise. 

Sorry for the huge wall of text, I just had a lot of thoughts about this and wanted to get them out somewhere. I want to hear other people’s thoughts on all of this, does any of this make sense? 

ps: after rereading and thinking all of this over, Abby has some things in common with Crying Child, but I don’t think she will become the bite victim like Crying Child, they are just both similar children. So the Abby being Elizabeth parallel/theory still stands. There are more things that I want to say and flesh out my theory, but it would be even more text, so I’ll leave it here and respond if anyone has questions.

TLDR: Elizabeth is Abby, Game Mike is Vanessa, Book Charlie is Movie Mike, and Sammy and Game Charlie are Garrett.
