Ella Owari

Backstory:

Inori, aka Owari, her friends Niko, Tora, and Hana, her mentor Yuuki, and her little sister Amai, are from YV-753. The name is unofficial as this dimension calls itself Earth 899, however, the only people who use this are Marvel and themselves. This dimension has been affected by a virus called... well... virase. It is feeding off of specifically the beliefs of other people, turning them into mindless zombies. Inori was a lab rat in this havoc experiment, but nothing affected her. Or at least... her memories, beliefs, politics, they all stayed. However, all of that was exaddgerated to an extreme, unlike her friends, who turned into mindless zombies. Once Yuuki and Amai were affected, Owari went crazy and... How did the interdimensional scramble happen?

Important characters:

Inori Mokushiroku is usually really happy. Her innocent age can be compared to Sayori in a way, at least before she became depressed. Her megalomania rampage can be compared to Mina Loveberry except for the fact that she HAD to die since she has both broken and alone. It should also be taken into account that Inori's parents are dead and she is a legal adult in both our world and her world, and also the only guardian of Amai. Inori was tested as a guinea pig for mind control and instead of Inori being controlled, she got... "exaddgerated" as the movie calls it. The only suspicious thing at the time is that she stole a massive amount of virase (about 3kg). Eventually, Owari becomes insane after Yuuki and Amai got controlled and she runs to... somewhere.  After a mysterious encounter, Owari is now a demigod and she can't manipulate time, but she can cause chaos and discord. She is taking a lot of dimensions together for an "infinite party" as she calls it: A Maximum Ride dimension before the events of Maximum Ride, Peter B's dimension after the Spider-Verse (or at least the first one), an IDW Ghostbusters dimension after TMNTGB2 but not following the 2018 Annual, a Cosmo Girl dimension after the events of Frozen Earth, and a Real Ghostbusters dimension in a 1992 Spring Break, so, April.

Dr. Sotai Ron is the head creator of virase. He is trying to take over the world using the bubblegum pink liquid, which spreads itself into other people forcefully and manipulates minds into mindless zombies. Dr. Ron has the final version kept inside of Earth 899, but Inori took an early version of the virase that she can manipulate at will. Dr. Ron usually introduces himself as a nice guy, but he's actually evil. His father was an army leader and he didn't like that, and he thinks if everybody agreed on everything all the time, there was going to be a slip-up one day, and it would probably result in Ragnarok. So Dr. Ron took it upon his own hands to be a Steve Jobs and say "INTRODUCING THE VIRASE" just so he can keep everybody neutral. He mind controls everyone to do factory work just so they can keep the peace. Artistic freedom is gone. Phones are not needed. Nothing is needed. Nothing except for peace. He kinda reminds me of Gendo Ikari, but there is definitely someone who represents him better.

Niko Tsukikage is a close friend of Inori. You could even say the two kids were dating at the time. Unfortunately, they weren't. How sad, R.I.P. Nikowari 1989-1992. Niko was trying to fight the urges of the scientists but he had to go all cookoo eventually. I don't know what happened at this point, but I'd say that Niko killed a man.

Maho Shijuuni and Hana Taiyokei were also close friends of Inori, but not as close as Niko, Yuuki or Amai. They were probably a real couple. Their ship name is either Hanaho, Hamaho, or Mahana.

Yuuki Shirobara has taught Inori as a child how to do her dream stuff. He was like a father to her whenever her real father wasn't around. And yes, Inori's father wasn't around that much in the first place. Apparently he didn't resist to the virase, instead he accepted it into his life, as he "knows he will get out of it someday". As a beta tester, Inori knows that the virase isn't just a voice in his head, it's a literal brain killer, and it is eventually going to replace Yuuki's brain with their own. And even if Yuuki did get out of it, he would be dead because the virase would go straight for the stuff that matters the most.

Amai Mokushiroku is last, but obviously not least, in the list of people Inori cares about and people care about her back. Ever since their parents died, the two sisters started to live alone. Amai still went to school, but one day, they just all of a sudden closed to get "Glasis Vixia" out there to the world. Glasis Vixia is the name of the project for mind control. It has been approved by the government and the people, or at least, the top speakers of the people. A lot of other people were like "no, that's wrong!" Inori was not one of these people, but Amai was, and she would tell the 899 version of Catherine her hatred of the plans. Mrs. Kasa Niji, Amai's teacher at the time, was one of the top speakers who actually disapproved of the practice of Glasis Vixia. Tl;dr, Amai is sweet, but super political for her age. When she was mind controlled by the virase, Inori has finally realized the scientists' actions were wrong, because the brainwashed Amai doesn't care about "family", or "friends". She cares about no one but herself, because there is no care for others without love for others, and you can't love something more than the other if you want peace. That's how Yuuki feels now, that's how Niko feels now. Maho, Hana, Kasa, definitely Dr. Ron, and if Owari doesn't escape, this is going to be her future.

Prof. Roger Baugh, at least in the Real Ghostbusters dimension in 1992, was a simple man. He just taught at the CCNY and he feels emotions? His first encounter with Owari was when his TV merged with a 899 TV. Possibly Yuuki's. Inori, still going by Inori, knocks on the door, asks if Roger is Yuuki, and then she shows photographic evidence as which Roger responds with "I never wore that but yeah, that's definitely me." (I don't know if Photoshop was real at the time and if it did I did not know if the consumer version was any good so good luck with that!) Inori keeps saying fucked up shit and then Inori tries to chase him. When she catches up to Roger, she sends him to a random place in town. It just happened to be the Ghostbusters' firehouse. While Janine was dancing with Egon. In this dimension, Roger and Janine were dating in high school instead of post-Season 7 like in semi-canon-land, and they had to break up due to Roger going to a different school.

Dr. Egon Spengler of CA-568, also know as Dan Kanevra in the script, got stuck in the plane of the multiverse after an encounter with Owari. Dani Shpak, also known as Lainey, came along with him to save him but she ended up being dragged down with him. Along with Prof. Norman Dweeb, who fell to find his dog, they became the Knights of the Square Plane Table! With their trusty horses, Honey Pie Pony, Checkers, and a literal coconut, they try to stay alive in the plane as long as they can because they have to.

Important Objects:

Virase is the pink goop Owari used to bring herself onto 5 separate dimensions.

The name of virase is a derivative of virus, of course, and it can be compared more to a deadly computer virus or one of those zombie computers rather than an illness, since it doesn't kill the mind of the host but instead controls it. Or at least, that's the only thing the final version was capable of. The demo version, however, was said to be unworking by Dr. Ron, but it builds up to the mind overtime. It manipulates the mind of Inori by agreeing with her mind on things and then turning them chaotic. Inori appropriately acted the same way and she can now use the virase to her advantage. She can now open rips into dimensions without consent, but with the price of most of the place being covered with virase rain. Nobody even knew that New York was in trouble because it was cloudy for weeks. Both versions of virase are capable of replicating things. The final version of virase can eat and replicate the human brain, possibly the human body, but the demo version couldn't exactly replicate anything until Inori's encounter with the... you know what. At this rate, Owari can generate solids, liquids, and gas and she can even generate things that sound and feel like their counterparts (this is handbook information). Scent is not as important, and if you smell virase, it stinks, so that's one big giveaway. They smell like shit but they aren't drenched in it. Apparently, when in contact with the human body, or just DNA, demo virase can make you "not yourself". As any wispy creature, you have the ability to glitch but only the SGB have truly mastered glitching hardcore. If you glitch as a human, though, it HURTS. Ray and Egon can see the audience from the real world (or at least that's what we'd like you to believe) and Ray can communicate with other people from the real world like it's a documentary. Spectral Peter is the only other person that knows this. Cynthia can also see through the audience, but sometimes she says weird stuff relating to Owari.
