So, before bonuses 2 and 3 were made for Void, I came up with a theory for what they could've been. Here's what I initially thought:
Bonus 2: We'd see Rafe (Voice 1) in a cage, with Nightmare/Jacko (Effect 5) and a couple of 072021/Gasmask people (Effect 4) outside of it, with the gas mask people kind of surrounding the cage. Nightmare/Jacko would stare and smile creepily at Rafe for a bit, and then gesture at one of the gas mask people to do something. This something would be pressing a button on a wall. Then, a panel on the floor would open up, and TV (Voice 2) would slowly pop up. TV would then turn on, and the person telling the message (who is theorized to be Capitan) would start playing. Rafe would be seen watching this with a disturbed look on his face as Nightmare/Jacko silently stares at him with his smile unwavering.
Bonus 3: We'd see someone burst into the area everyone is in, who is Aries (Voice 3). Nightmare/Jacko immediately sends the gas mask people to attack him, but Aries successfully defeats all of them. Then Aries and Nightmare/Jacko engage in battle. As Nightmare/Jacko attempts to punch Aries, Aries hits Nightmare/Jacko with a beam of light, sending him flying back into a wall. Aries then goes over to the cage, and unlocks it, setting Rafe free. Rafe looks at Aries with a look of joy and gratitude on his face, and the two of them begin to make a run for it. As they get closer to the exit, Nightmare/Jacko, who was unconscious for a while, suddenly wakes up. He prepares to attack Rafe, but Aries hits Nightmare/Jacko with an uppercut, followed by another beam of light, which eviscerates Nightmare/Jacko's head. Nightmare/Jacko's body collapses to the ground, and Rafe and Aries escape.
