Universes

Universes are a concept in fiction which was introduced to the SiIvaGunner lore during SilvaGunner: Rebooted.

Main universe / CCC universe
The universe where SiIvaGunner's home in Grandiose City resides and the universe where The SilvaGunner Christmas Comeback Crisis takes place. As of Season 3, rips in this universe are being created by the SiIva A.I. developed by the Haltmann Works Company.

This universe hasn't progressed past Christmas 2016, as Haltmann created a "time lock" so he could profit from rips forever, however figments from the future still come in through time rifts.

As explained by The Voice, there are two realms in this universe: the digital realm where figments reside, and the real world where humans and SiIvaGunner reside.

Reboot universe
This was a parallel universe to the main one created by The Voice, and was visited during the entire Reboot event.

The only difference between this universe and the main one was that the three biggest memes used on the channel are different: Instead of "Meet the Flintstones", rips used the intro themes for The Simpsons and Family Guy; instead of "Snow halation", rips used "GO MY WAY!!"; and instead of Loud Nigra, rips used the Howie scream.

This universe no longer exists as of "A Grand New Era ~Ending~", since The Voice merged this universe into the main universe, discarding "Snow halation" in the process, however Chad Warden used the power of the MF Like Button to bring "Snow halation" into the merged universe and kill The Voice's physical form.

KFAD universe
The universe where the King for a Day Tournament and its sequel took place, as well as The SilvaGunner Spooktacular Halloween Horror Special: Part III (and possibly the previous two parts as well).

Not much is known about this universe outside of the events it is featured in, however it seems that John Notwoodman's company, King for a Day Tournament Enterprises, creates rips in order to receive funding.

This universe doesn't seem abide by the figment/human realm split, since many fictional characters (which would usually be designated as figments) are seen next to human characters in the tournament, and on the MOJO!!, it is seen that Studio Gunner, a fictional location, resides next to the, a real location.

Trivia

 * The inclusion of universes may have been as a reference to the 0.5x A presses meme and its use of a  glitch known as "parallel universes".
