Spoilers!!! You were warned

There are people like gachatrap (YouTube), who believe Mimic from the Tales from the Pizzaplex is nothing but a stupid not confirmed fan theory

Well, I just watched some very well known people by me videos

And there was confirmed why Mimic, Tales themselves, are Canon in modern FNaF Games

By Modern Games means a new Chapter, which was started with Help Wanted

BUF confirmed, after explaining Mimic Story (Spoilers!), that

1) Mimic was born by Edwin Murray in 80's, before FNaF 2, events of which (Game) are happening in 1987

2) After Freddy Fazbear Pizzeria Simulator (FNaF 6) William Afton, my favourite Character, died officially, but was stuck in Personal Hell (Ultimate Custom Night), but even if we, players, will beat 50/20, it won't help much. William always be trapped in Hell

3) William Afton's (before dying and becoming Springtrap) laughing is different from Mimic (Burntrap):

William Afton:

A/N - Only Laughing

Mimic (Burntrap):

4) Mimic knew about UCN events

5) If we'll take a look at Alternative True Ending Burntrap Ending - while Burntrap is only laughing and screaming and etc, Glitchtrap is copying Animatronics' Words. Even UCN Nightmare's "You will not be spared. You will not be saved"

6) Glitchtrap was copying Tape Girl's "Can you hear me?" and "Hello?"

7) The very first Tales from the Pizzaplex Book came out during Help Wanted, in 2019

These were BUF's proofs

Now second person, Liberty

Trade Publicity answered to her with this:

Also take a closer look at these two paragraphs in 7th Tales from the Pizzaplex Book's Description:

Even if I don't have Books, only The 4th Closet, which is part of Novel Trilogy, which takes place in Alternative Universe

Tales from the Pizzaplex caught my attention

But even if these proofs not enough for you, then I don't know what kind of person you are, believing William Afton came back

His famous "I always come back" worked before

But after FFPS it's no longer working

True, I'm sad William dead, but maybe it's for the best?

Only DLC Ruin for Security Breach and other future Games can explain it to us

As BUF said - William Afton officially dead, he's trapped in UCN

But it leaves an issue - Princess Quest

Meaning why Cassidy is still here?

And what it has to do with Mimic as Glitchtrap?

Yes, it's Official William has Springtrap and Scraptrap forms only

While Mimic has Glitchtrap and Burntrap forms

My personal guess is Cassidy did as Old Man Consequences asked her - "Leave the Demon to his Demons"

See you soon

BlueAlastor, Out

P.S. Tales from the Pizzaplex are Canon and are Prequel to Security Breach, meaning GGY can also be Canon and Gregory existed before Game Events
