In this Comic, Silent "The Player/Avatar" was gathering the Night Guards
(plus Pizzeria Visitor and Phone Guy) just as Shadow Sonic gathered Golden Sonics before and "again" in this part.
It was played by Dr. Golden in order to carry out his Evil Plan...

This is also a reference to Silent's connection with Modern Sonic and Salvage Sonic (FNaS3).
Silent treat Modern Sonic as she were with Sonic from her real world when she fought against Infinite.
And Silent treat Salvage Sonic as the Scariest Character Number 1.

Also, Nightmare Yoshi prototype version Skin: Macula Horror Yoshi

This is somewhat actual in Fiercy Forces version.
