Percolation (Gerosha Chronicles)

Percolation was a fanfic of Marvel: Avengers Alliance by Playdom, taking place in a "What If?" spin-off of the Gerosha Gaming Universe of The Gerosha Chronicles dubbed the Gerosha Crossover Gaming Universe. It is an unofficial crossover with the Marvel: Avengers Alliance Fanfic Universe, acting as if a crossover with the actual Earth-12131. It centers around explaining how Extirpon could have become an agent of SHIELD going by the moniker of "Agent Opendi" for four months, while taking advantage of two Marvel characters that never appeared in the game canonically - by portraying them as having been recruited to SCALLOP.

On Saturday, June 21st of 2014, the sequel Percolation: Legends was proposed as a tie-in with the release of Marvel: Avengers Alliance Tactics on Facebook.

Plot
While experimenting with incursions, Dr. Doom accidentally unlocked access to a stray universe modeled after Cataclysmic Gerosha. He found this new multiverse thread very intriguing, and sent Mystique in to explore. She managed to break into SCALLOP headquarters, taking Darius Philippine and other officials off guard, and stole an AI backvisor from the Project: Earwig experiment room. It was one of two. She stole some intel while disguised as a SCALLOP agent, then brought it back with her to share with Doom. She used the stolen backvisor to take control of Doctor Strange, turning him into her minion. Darius eventually noticed the backvisor to be missing, and video revealed that a shapeshifting imposter had been impersonating several agents to steal both the backvisor and intel. Darius sent out an immediate alert for anyone who could track down a shapeshifting spy.

However, Doom's toying with Gerosha fabric further led to a cosmic storm within the Percolation Wave, like the one that yielded the radiation that produced the Fantastic Four. This produced a Zeran hole that bridged Doom's world with Darius'. As the Pulse hit Earth-12131-F, Nick Fury scrambled to assemble as many Avengers as he could to work with him and SHIELD to get to the bottom of it. A secondary burst of energy during the Pulse, however, led to the Percolation Wave sending two Marvel heroes and two Gerosha heroes to swap universes.

Extirpon suddenly found himself in the middle of Hell's Kitchen, witnessing Daredevil in a battle and being very confused about it. He was soon joined by an equally lost and confused Isitoq Sundue, the then-current Anarteq. Arriving near Boston in Earth-G7.2.1 and being equally confused were Jubilee and Danny Ketch. Various Marvel meta sources latched on to Extirpon and Anarteq, acting as a substitute Marlquaan for them. Since Anarteq was a Phexo, he began behaving as if he had the X-Gene. Jubilee found herself behaving as if a Phexo or Marlquaanite, with no other difference in her abilities. Likewise, the Marlquaan latched on to Danny Ketch as a substitute meta, allowing him and Noble Kale to become Ghost Rider in the Gerosha timeline.

Anarteq and Extirpon saved Daredevil from a Sentinel, who had teamed up with the Hand. However, Mystique and Doctor Strange arrived. Extirpon nearly killed Mystique by feeding off her hatred, and caused her to cough up spiders. She retaliated by sending Strange to fight Extirpon. The two of them battled, and Extirpon's negative battery was damaged in the fight. However, he managed to find and identify the AI backvisor controlling Strange. He correctly identified it as being of Hebbleskin Gang origin. Destroying it, Extirpon allowed Strange to regain his senses.

Strange chased off Mystique, who was terrified of what Strange could do to her to get revenge. A very confused Anarteq fled to the ocean and swam back to Canada. He headed toward what would otherwise have been the Sundue family's native village in Yellek. However, Anarteq was distraught to learn that he was in a timeline in which the Order of the Oraphim and Sundue family never existed. Namor caught wind of SHIELD sighting an unidentified merman in Canadian waters, and so he went to investigate. It didn't take him long to catch up to Anarteq. The two had a discussion about Anarteq's predicament, and Izzy was then redirected to SHIELD custody. Nick Fury promised to house Anarteq until they could find a way to return him to his home dimension.

Strange arrived shortly thereafter, with an injured Eric Opendi in tow. He managed to repair the battery mostly; but Eric found that he had a hard time efficiently charging when in a foreign dimension. Therefore, the healing of his battery and charging of his power were very inefficient, and that effectively limited the time he could spend as Extirpon. Nick Fury instead offered Eric a temporary job as an agent of SHIELD, dubbing him "Agent Opendi." Eric readily resigned himself to the post, feeling he had nothing better to do with his time until he could be sent home.

Nick was contacted by Xavier, who confirmed that Jubilee had gone missing. Johnny Blaze suddenly reported in that Danny Ketch was nowhere to be found, making Johnny temporarily the only Ghost Rider in town. Phil Coulson and his team verified that there were no trace signatures of Danny or Jubilee anywhere in known 12131-F domains.

Meanwhile, Ghost Rider and Jubilee found themselves in Boston. Janet Phillips, a cousin of Ashley Phillips, was seen by Jubilee to be interacting with Screwworm Network goons. They raided a warehouse in town, and Jubilee ran in to stop them. However, the Crooked Rainbow arrived and attacked her. She was able to fend them off long enough to run away. However police arrived to aid the Rainbow terror group in hunting down the "suspected Marlquaanite menace."

The Rainbow goons gave pursuit of Jubilee, determined not to stop until they had raped and killed her. Ghost Rider caught up to a few of them, and immediately attempted to burn their souls, as he could smell the pain they'd inflicted on religious minorities. Some of them proveed to be too far gone for the penance stare, so he was forced to simply engulf them in flame and dispose of them. Police split up, with two thirds of them continuing to go after Jubilee - whom one Rainbow activist initially identified as the "bigot," even though they attacked Jubilee first! The remaining third made a halfhearted attempt to pursue Ghost Rider; deciding they'd prefer to target the weak, lost, and terrified girl rather than the scary monster that could actually fight back.

Microwave Mouth eventually caught up to Jubilee, and the two battled briefly. However, Ghost Rider lost the police and found Jubilee battling Microwave Mouth. He immediately sensed the malice in the latter, and fought back. That was when the Gray Champion arrived. Gray decided to let Ghost Rider finish off Microwave Mouth, before letting his presence be known. He then directed the displaced heroes to an alleyway, so that he could learn who they were and why they are helping him battle his foes.

Danny forcibly sent Kale back inside, so that he and Jubilee could be rational with their new friend. However, Daniel warned that evil was still very much afoot in the streets. They would need to head indoors, or he would've compulsively changed back into the Ghost Rider. Gray agreed to transmit them to Hea's apartment. Hea Pang was caught off guard by the surprise guests, whose mannerisms proved confusing. The group awkwardly deduced that Hea and Gray's guests were from another universe. Hea got in contact with SCALLOP headquarters immediately, asking them if they'd noticed any recent activity from others who appeared to be otherworldly. Team Gray and guests were called in to SCALLOP immediately.

Darius and company interviewed Jubilee and Ghost Rider to learn more about their predicament, letting Team Gray know that they would be contacted if needed again. Darius first inquired of Jubilee if she were a Marlquaanite. She looked puzzled, then said no. When she claimed to be a mutant, Darius inquired if she were a Phexo or Meethexo. This confused her. Danny replied that they don't even want to know his backstory. Jubilee inquired if there were a way to manipulate the Marlquaan to locate the cause for her and Danny's percolation into G7.2.1, and if they could establish communication with 12131-F or even send the heroes back. No sooner did Darius state that he was unaware of the means to do this, than he received a phone call from Seth Lambrelli about a new Marlquaan ruby that appeared to be able to communicate with alternate realities. Jubilee was sent to retrieve the ruby, while Ghost Rider was assigned to aid Navyrope in an undercover operation that was "off the books."

Suspecting that Lambrelli Labs had the new ruby, the Icy Finger decided to set up a roadblock to intercept whoever they found carrying it. Jubilee made the mistake while taking a motorcycle back from Akeny to Louisville of opening up the bag the ruby was inside of, and looking at it. Screwworm spies caught her with it, and signaled each other to give chase. They sent recruits after her. When finished helping Navyrope, Ghost Rider was contacted to rendezvous with Jubilee. He did so in the nick of time, though the Gray Champion arrived to help out.

The heroes arrived in the clear, when they suddenly deduced what was missing: nobody had seen or heard anything about Extirpon in quite a while! The Marlquaanite classes being faced were exactly the kind Extirpon would normally battle. As they headed to SCALLOP headquarters, Gray contacted Hea about what was going on. She suggested that they search for any signals that would appear to be searching for them while using the ruby. Amazingly, SCALLOP engineers found a way to accomplish exactly that very goal. Nick Fury was shocked when he received a phone call from Darius Philippine. The SHIELD and SCALLOP directors quickly exchanged notes to get caught up on their unique predicaments. They began establishing a way to control their own Percolations, so the hero exchange program could be controlled until a time when it was no longer needed. They agreed that even if they occasionally allowed more heroes to invade each other's universes, that allowing Extirpon and Anarteq a way back home was top priority.

It was not long after that conversation that the Louisville base came under attack by Icy Finger goons. Gray and a variety of other unnamed Marlquaanites battled to protect SCALLOP headquarters from the Icy Finger's ruthless onslaught. Doctor Strange was alerted right away, resulting in the Silver Surfer temporarily percolating to G7.2.1. He managed to defeat most of the Screwworm Marlquaanites, before transferring back to 12131-F. Strange noted that Percolations appeared to only be stable if there were an actual exchange - or if a copy were made. Such an exchange, to be controlled properly, would have to be timed on both ends.

It took four months before the Marvel and Gerosha heroes were able to get everyone correctly returned to their proper universes, and then they destroyed the mechanism with which Doom contacted G7.2.1 in the first place. This led to them semi-permanently severing ties with each other. Eric, upon transfer back, had his mind wiped by Xavier, so that he wouldn't remember any good times with his new Marvel friends. He woke up in his own universe in the middle of Montana, not remembering anything about 12131-F and not sure how four months of his time mysteriously vanished. However, he noted that his Emotion Battery was now fully operational again.

Strange and Xavier got some help from Madame Web, and they traveled to G7.2.1 one last time to make that sure Hea, Gray, and Darius didn't remember much about the Percolation events either. They returned to 12131-F afterward, and erased a few memories there as well. They decided that the Avengers were way too busy dealing with their own world's weirdness to care about the trauma that could be inflicted by remembering and bonding with Gerosha heroes. Therefore, they left those memories alone.

Later on, it was revealed that SHIELD cloned Extirpon upon realizing his usefulness. The Fantastic Four used their knowledge of cosmic rays to turn the clone into a near-perfect replica of the original. However, the clone had difficulty forming the same emotional bond with Sif that the original enjoyed. Instead, the clone found himself in a complicated relationship with Omega Sentinel, before eventually leaving her for a clone of Pam Marcones, and the clone of her son with the original Eric.

Option: Funny mode
This variation of Percolation has it that while few adverse side effects of the Percolation affected Earth-G7.2.1, there were considerable impacts made to Earth-12131-F. No one is certain if the effects are reversible, but they mostly affect characters' voices. For example:


 * Nick Fury now has the voice of Don Corleone.
 * Maria Hill now has a nagging voice similar to that of Polly Mindoche.
 * Captain America now has the voice of a cat, and is sometimes called "Catpain America."
 * Daredevil now talks like the Christian Bale version of Batman.
 * Dr. Strange is now very soft-voiced, and mutters his words so his discussions are barely comprehensible.
 * The Hulk must include product placement in every sentence.
 * Iron Man cannot use his high-energy laser without saying: "Imma firin' mah lazor!!!!"
 * Karolina Dean has this same problem.
 * Anyone attacked by Human Torch will now shout: "It buuuurrrrrns!!!!," in reference to CD-i Ganon.
 * Iron Fist talks like a Mexican luchador stereotype.
 * Luke Cage cannot brawl with someone without saying: "Man, I'mma BEAT yo ass!"
 * Nightcrawler cannot say "night" or his own name, without "night" coming out as "nickht."
 * Phoenix cannot be onscreen battling anyone without "Lisztomania" by the band Phoenix playing in the background somewhere.
 * Sif is begrudging of Agent Opendi, since she fell in love with the original and the clone rejected her in favor of Omega Sentinel. She has an even thicker Southern Belle accent than Rogue now.
 * Thor now has a Georgia / Tennessee redneck / hillbilly drawl.
 * Loki sounds like a high-pitched Pete from old Mickey Mouse cartoons.
 * Valkyrie talks like an answering machine.
 * Elektra now has a very deep man's voice.
 * Taskmaster now has the voice of King Candy from Wreck-It Ralph.
 * The Frost Giants all have Scottish brogues.
 * Tigra now has the voice of Tigger, and sometimes calls herself "Tiggra."
 * Red Skull now has the voice of Megatron from Transformers: Prime.
 * Wrecker has the voice of Bulkhead, a member of the Wreckers.
 * Hercules now has the voice of a stereotypical 1950s radio sports announcer.
 * Superior Spider-Man has the voice of O'Malley from Red vs. Blue, with the verbal tic of Betty from Kung-Pow.
 * Molly Hayes is followed by a college sports band into battle, performing stereotypical school fight song music whenever she battles enemies. This ideally would lead to a team-up bonus with Hercules.

Custom sprites
Up to 100 different sprites were proposed for inclusion in the game, based on the Gerosha Multiverse. Only about 54 mock-up sprites were actually produced, however. They were hosted on the Marvel: Avengers Alliance official wiki until January 5th of 2015, when the site voted to remove all fan art from its servers. The M:AA Fanfic Universe Wiki arose to fill the gap created by this exodus.

The Percolation Wave's influence was expanded to having xeroxed copies of 55 different Dozerfleet heroes, and placing their clones in multiple non-Dozerfleet universes, thus allowing regular Dozerfleet continuity to continue unabated whilst allowing these 55 to have adventures of their own in new worlds. The clones retained almost all memories of their originals up to the time they were cloned. Not all were cloned from the same time period, however.

Development
Around August 28th of 2013, the Dozerfleet founder joined the Facebook app for the game Marvel: Avengers Alliance. He was curious what the customization options were for in-game avatars, and was hoping to perhaps be able to add custom characters into the game. Alas, custom sprites of other characters were never made a true possibility by the game's developers. Wishing to be a good sport, the Dozerfleet founder proceeded with entering the game anyway. An entire story would be developed to explain how "[[Eric Opendi (MAA Fanfic Universe)|Agent Eric Opendi]" became a character, but without featuring him needing to feature utilizing any particular Extirpon abilities. The sprite customization options given were utilized as best as possible to ensure that the end result looked as close as it could to Eric's face and physique.  This way, "Agent Opendi" became the Dozerfleet founder's in-game avatar.  Other heroes would be gradually added to fanfics later, though there was some hemming and hawing about how to justify their inclusion.

DeviantArt distribution
On September 8th of 2013, a promotional image of Percolation was added to the DeviantArt collection "Video Game Pitches." It was marked a favorite by MRF Arts within minutes of upload.
