Gerosha Crossover Gaming Universe

The Gerosha Crossover Gaming Universe is one of many narrative universes to comprise the overall Gerosha Multiverse, homeworld of The Gerosha Chronicles in Dozerfleet Comics, with the Earth number designation of Earth-G7.2.1. Its emphasis is on proposing inter-company crossovers, something that Cataclysmic Gerosha and the Gerosha Gaming Universe are restricted from doing. The Percolation Wave has been able to access this universe almost immediately, and picked up its pace in doing so following the Great Marlquaan Storm of 2012. By contrast, its sister universes were resistance to the same phenomenon, although cosmic observations in those universes led to the locals becoming very jealous. Therefore, the Society of the Icy Finger feels obligated to gain control of the entire Percolation Wave phenomenon to rule the Multiverse with - in every universe in which there is an Icy Finger.

This universe originally served as a bridge for the Dozerfleet Megaverse to be introduced to outside universes such as the Marvel: Avengers Alliance Fanfic Universe, allowing the possibility for team-ups that would normally have been impossible. Since then, it became the basis for sharing Gerosha characters with the Dromedeverse and Eccentriaverse, as well as making Spiderverse fanfics in which Ciem got to play a role. It is the version of the Gerosha universe in which Geroshans get to join Dromedians and Eccentrians to form the Percolation Warriors, that they may save the multiverse from the newly-formed Triumvirate consisting of the Icy Finger, Gwirdons, and the forces of Xironooti.

History
The Percolation Wave became hyper-active in this universe beginning in WWII, when it transplanted a copy of Charles "Centipede Charlie" Hammerstein into Earth-12131-F. Aware that something related to the Wave that had been rumored to be a thing since the first century AD, the Society of the Icy Finger all across the Gerosha Multiverse became obsessed with the idea of one day mastering a way to control the Wave to their advantage. Thus began an arms race against the Order of the Oraphim for Marlquaanite Rubies - as well as the much-rarer Abdygalis Shards. Unlike the residents of Earth-G7.0.0 and Earth-G7.2.0, however, the residents of Earth-G7.2.1 were able to unlock access to and partial control of the Wave on their terms, with help from other universes that had prior unlocked partial control of the Wave - but at a price.

Events in G7.2.1 otherwise mostly played out the same as in Earth-G7, right up until shortly after the Great Marlquaan Storm of 2012. Extirpon and Anarteq were briefly stranded in 12131-F, while a few Marvel heroes found themselves wandering lost in G7.2.1. Efforts by both worlds to prevent a more disastrous incursion between the two realities from occurring succeeded, but only at the cost of multiple G7.2.1 heroes getting near-carbon copies of themselves generated by the Wave, and then displaced into 12131-F permanently.

After these events, history can, unless otherwise noted, be said to be consistent in this world with the history of Earth-G7, right up until shortly before the Great Battle for Little Rock. After that, Xironooti saving Rappaccini from getting himself trapped into battling Cherinob and losing results in the G7.2.1 heroes having to defeat a newer, stronger Multiversal Triumvirate, after the reforged Icy Finger and Xironooti's forces further forge an alliance with King Mogabir - who took over for Gwirmalesh as leader of the Gwirdons in the Eccentriaverse. The G7.2.1 heroes that are left must team up with the Knights of Cortascius and Camelry to form their own alliance: the Percolation Warriors. The main base for this new team winds up being Menehune in the Dromedeverse, a domed mini-planet terraformed from a relocated Gonggong moved to a spot between Earth and Venus almost close enough to become a second moon of the Earth, yet kept just far enough away to avoid becoming a proper second moon. In addition to this, the liberated Little Rock in Earth-G7.2.1 serves as a secondary location, with an embassy set up on Cortascius for an Eccentrian base for the Percolation Warriors in that universe.

Earth-G7.2.1 has also hosted a variety of experimental crossovers, dubbed the "Centipede in the Spider-Verse" series, which poked fun at late 2010s Spider-Man comics and movies by putting Ciem in them. A Centipede Lost in the Spider-Verse is set in the spring of 2018 in the prologue timeline of Sodality: Instigation, when Candi is still dating Tyrone. A Centipede Returns to the Spider-Verse has Candi rescuing the Spider Totems from Morlun, this time depicting Candi how she was after getting Donte back at the end of the Sodality: Adaptation timeline. Roughly around this same point in time, Candi visits a version of the PS4 Spider-Man video game's universe, only for it to collide with variants of the Mirror's Edge: Catalyst universe in Percolation Warriors: Spider-Faith. Also around this time, the Gwen from Spider-Gwen: Gratia Ruinam gets counseling briefly from Candi in Not Quite Full-Circle

A later, more stable Candi from just after the Battle for Metheel timeline is shown debating with Mary Jane about the J. Scott Campbell pose controversy, and the price of fame, in Candi vs. The Pose. This older Candi lends her wisdom as well to a variation of Earth-199999 Peter Parker in A Centipede's Way Home, and then visits Miles Morales in A Centipede Once Again Saves the Spider-Verse to prevent the plot of Across the Spiderverse from happening.

As of 2023, the Percolation Warriors Saga is set to be the only official to-be-published-for-profit crossover work for Earth-GØ that involves Earth-G7.2.1, even though the Dromedeverse and Camelorum Adventures are technically the host world and series for that saga.

Development
Crossover Gaming was developed as a sub of the Gerosha Gaming Universe on August 28th of 2013, as a way of dealing with non-canon crossovers. The intended goal was to give Percolation a specific universe to dwell in, but it was left open-ended for other similar games to occur. Percolation was written as a fanfic of Marvel: Avengers Alliance to explain how Extirpon could be in the game, going by the alias of "Agent Opendi." This was to justify the Dozerfleet founder using that name to play the game on Facebook. As Percolation Wave mythos expanded, Percolation: Legends was written to open up the entire Dozerfleet Megaverse to having variants for the Marvel: Avengers Alliance Fanfic Universe.

As time went by, Earth-G7.2.1 also became the de-facto universe from which to borrow Gerosha characters for use in crossovers such as the Percolation Warriors Saga, or to have them make joke cameo appearances in Camelorum Adventures. Setting the Percolation Wave's highest activity rate in the Dromedeverse allowed for Dromedeverse pocket dimensions to create additional plots for that series, as well as making it possible to use the Dromedeverse as a bridge between Earth-G7.2.1 and the Eccentriaverse, thus allowing for a world like the one teased in Earth-G5 - a world with Ciem in it who is aware of both the existence of the Grillitan Diner franchise and aware of Volkonir.

Beyond plotting for this, Earth-G7.2.1 also served as a basis for crossover comics involving Ciem in variations of the Spiderverse saga from Marvel. This was to capitalize on some children getting Ciem confused with Spider-Woman, and to compare and contrast Ciem with Spider-Man to demonstrate how they're ultimately not the same character, in spite both having good reflexes and a bug emblem on their chests. While A Centipede Lost in the Spider-Verse poked fun at how little Ciem would've been useful against Kingpin in that movie, A Centipede Returns to the Spider-Verse demonstrated how Candi could have oddly proven to be extremely useful against Morlun. Furthermore, A Centipede Once Again Saves the Spider-Verse illustrated that Candi teaming up with Italian Spiderman could have dramatically negated the entire plot to Across the Spiderverse. Not Quite Full-Circle showed Candi counseling a broken Gwen Stacy, in a side to the canceled Spider-Gwen: Gratia Ruinam, which would have been a Sims 3 adaptation of the Life of Gwen Stacy arc in the Earth-65 Marvel timeline. Candi vs. The Pose mocked the J. Scott Campbell controversy regarding how he drew Mary Jane on a Spider-Man comic cover. Percolation Warriors: Spider-Faith showed how the Percolation Wave and its fanfic potential could have devastating consequences not only for Ciem and Spider-Man but for the worlds of Swappernetters and Mirror's Edge as well. A Centipede's Way Home furthermore illustrated how small changes involving Ciem and Italian Spiderman could've made a small difference to the plot of Spider-Man: No Way Home.
