1. "The nightmares are possessed by the bullies/Terrance or Michael possesses Nightmare Foxy"

They're not possessed by anyone and even If google said they were its wrong. Because google also said Elizabeth was William's wife, Chris and Mike's girlfriend.

2. "Mrs Afton has bright ginger hair and green eyes"

Canonally she doesn't and since Clara represents her, her hair technically is blonde. Plus her eyes could be blue as well, its not confirmed that her eyes are green.

3. Clara isn't Mrs Afton's canon name nor has one been said for her

4. "Chris is dating his nightmares"

Lately according to lore CC likely isn't even the one suffering from the nightmares nor is his name Chris. Plus why would Chris date nightmare like creatures that haunted him?

5. "Michael is the only one who can't eat"

All the Aftons are dead so none of them canonally can eat or should I say taste food. Plus to be able to consume food means the body can break it down of course if you're dead that isn't going to work well for you.

6. "Michael has kids with Ennard"

NO HE DOESN'T and i'm positive he never had any since he didn't want his family line to continue thanks to his father. Plus Ennard canonally is possessed by his sister and remnant that likely is either hers or the mci.  Plus he doesn't seem like the type that's sexually attracted to ROBOTS if you ask me.
          INCEST IS NOT WINCEST

7. There is no proof that William was abused as a kid or that his father was abusive/performed experiments on him.

8. Michael was forced to bully cc by his friends

He wasn't HE was the one who encouraged his friends to help him force his  little brother to give Fredbear a big kiss.  While he taunted his  little brother.

In the minigames the only bully other than Mike was Bonnie who spoke which was in blue, CC spoke in white and Mike spoke in grey.

9. Chris is a fanmade name for CC that was made in 2015, (7 and a half years ago.) Its not his canon name.

10. There is no proof that he possesses Shadow Freddy. Plus how is he going to possess something that isn't even a psychical being? As far as the files go Shadow Freddy is Nightmare. Nightmare confirms in ucn that he is William's wickedness made of flesh.
