"Imagine It!" Fan-Comic / "Hideaway & Hunt" Fan-Game Connection Comic.

Haz-Hint # 1: (aka. Security Breach Faz-Fact in Fierce Forces version)
Clone Sonic "Guise-Up!" is a disguise of Salvage Sonic "Gory-Up!" in Fierce Forces.

In other words he appears in a Holographic version, that is active during the day.
At the night (when the hour strikes 12 AM), the fake appearance just simply fades.

"Why does he needs a hologram during the night, when none of the "visitors" are looking at him?! Oh wait... except Silent. Yikes..."
(Actually nobody visits Sonic Heroes Tera Pizzaomnia, since the Place and Event takes in Fierce Forces Arcade Machine in "Imagine It!")

Those who selected in the previous poll:
"Wait... I think... I saw him somewhere else before" you were correct! Congratz!

Clone Sonic "Guise-Up!" appeared in the earlier posts of "Hideaway & Hunt" game page.
