Go To

Flashpoint 2: Advent Solaris is a fan-fiction written by Empire-of-the-East. As the title might suggest, it so happens to be a Crossover of the DC Animated Movie Universe with Sonic the Hedgehog. Yes this actually is a thing now.

The storyline serves as a Continuation of the DCAMU's universe, following the final film, Justice League Dark: Apokolips War. Following the events of the aforementioned movie, Barry Allen wakes up in a newly created timeline, only to discover that more things are different than any previous timeline his time travel has created up to this point. At first, he's willing to move on and accept the changes for the sake of being with his beloved - though that's when a certain mad scientist shows up and a certain intro sequence is brought into novelized form. Ever the superhero, Barry decides to get involved. He ultimately proves to have little idea of the rabbit hole he's falling down.


At the time of this being written, the fic is at it's sixteenth chapter, with a total of thirty being planned according to it's Archive of Our Own page. The fic is also available on other major fanfiction websites, but this page uses the Archive of Our Own chapter listing as that is the version linked.

Due to the nature of this fic continuing off of the final movie of a series, there are naturally unavoidable spoilers about said movie.



  • Adaptational Badass: Multiple examples of this trope exist:
    • Mephiles is shown to have more powerful time-related powers in that he can present visions of even the "erased" Apokolips War timeline, and it is implied he can theoretically travel to it as well. He also seems to have some type of control over shadows. By the time of Chapter 13, Mephiles' power upgrade reaches new heights when it's revealed He's one half of an amalgamation of Darkseid and Trigon.
    • Shadow is described as being more stronger than his typical gameplay-limited depiction as well, with his punches being compared in Chapter 5 to Superman's own; the full extent of his power continues to expand as the story goes on - even though it's arguably justified when the origins of his DNA donor are revealed. Not only is he about as durable and has as hard a punch as a kryptonian, but he can also absorb the energy from the omega beams - fueling his chaos blasts.

    • Going off the specific Sonic game being crossed over with the DCAMU, Sonic gets a massive speed and power upgrade as well by comparison. He's roughly up to par with the likes of the other speedsters in this story and is fully capable of accomplishing feats just like them, though he is of course smaller in height to them. He later gains a connection to the speed force in Chapter 14, further cementing his power upgrade.
  • Alpha Bitch: At least three clear cut examples.
    • The first is the sole new character created for the fic, Lady Mairghread "Mairie" of House Mcloch who solely appears in Chapter 6, introduced as Elise's aunt who has bullied her since she was a child - among various other acts of cruelty and corruption.
    • Later on in Chapter 13, we are introduced both to Komand'r and the Queen of Bialya, who both effectively try to out Alpha Bitch each other before their boss,Mephiles, interrupts them.
  • Alternate Timeline: The Sonic Universe is treated as an alternate timeline of the DCAMU in this fic, having been created due to the flashpoint necessitated at the end of Justice League Dark: Apokolips War.
  • All There in the Manual: With this being a continuation fic, obviously the events of the film(s) this follows are explained, in, well - those films. Same goes for the Sonic games that occurred prior to 06, though some of their events do get recounted in dialogue and/or have their aftermaths shown.
  • Anyone Can Die: Lady Mairghread in Chapter 6 is built up to be a personal antagonist for Elise, though the entire character arc is concluded by the end of the chapter and Mairghread is removed from life at the very end as well. On the protagonists side, Mighty the Armadillo dies trying to save the life of Charmy Bee while on Angel Island, and became the first non-robotic Sonic character to perish in-fic. It's also very doubtful that every single civilian made it out okay when Eggman's robots chased after Elise & Espio in the New City district, nor all of the Soleanna royal guards when Blaze & Silver charged into the train terminal on their "mission". And let's not even get started on Crisis City...
  • Bad Cop/Incompetent Cop: In Chapter 3, the Soleanna royal guard reprise a role they had in the original game - forcing Sonic and Barry to guess who their captain is. They do this just because they think it's funny. They also insult Barry for his job as a forensic scientist. In later chapters they have a key role in, they are shown getting either gunned down by robots or straight up beaten to hell by the likes of Silver and Blaze with total ease. Yet they still try to deny those trying to save the day entry to where they need to go.
  • Big Bad Wannabe: Two prime examples:
    • Going along with the specific Sonic game crossed over with DC here, Eggman reprises his role as the first villain to formally arrive in the story until the real villain shows up in Chapter 3.
    • Lady Mairghread "Mairie" Mcloch in Chapter 6, who spends a good portion of the only chapter she's even in being revealed as an antagonist to Elise, even having one of Elise's ladies-in-waiting tortured just for standing up to her and musing about having her men assassinate lower class citizens. Thanks to Metal Sonic her "screen-time" gets cut rather short.
  • Big-Lipped Alligator Moment: When Doctor Fate and his current avatar (confirmed not to be the same as any named ones from the movies or the comics) shows up in Chapter 16 it's not only basically out of nowhere but also in terms of explanation only assumed by the heroes but not really stated by him if he's fully working with Mephiles/Darkseid or just supports the "order" they'd create a la Injustice 2.
  • Broken Hero: It is apparent that Barry is not quite the same as he used to be following the events of Apokolips War, as he suffers from clear signs of Post-Traumatic Stress Disorder as the memories still persist. Despite this, he still tries to act like his usual self the best he can.
  • Challenging the Chief: Barry takes it this way when Sonic mentions being the "Fastest thing Alive".
  • Crossover: The entire premise of the fic itself. Barry Allen finds himself waking up just in time to witness the opening of Sonic 06, and from then on proceeds to get involved in the plot going on around him.
  • Chest Burster: During his fight with the sons of Darkseid, Shadow does this to Grayven using chaos control to teleport inside him and literally tear him up from inside before bursting out.
  • Cosmic Retcon: The one at the end of Apokolips War is ultimately undone with use of another, villain-performed retcon when the old timeline from before Superman invaded Apokolips is restored.
  • Crossover Combo Villain: Let's just say that Mephiles' previously mentioned power boost gets a tad more serious later on. Turns out he (and by extension Iblis) is quite literally Darkseid and Trigon combined into one being. Repeat that: Darkseid and Trigon. As one being.
  • Darker and Edgier: By Sonic standards, certainly. By DCAMU standards, it's about on par with the movies. Things start out relatively light-hearted, until Mephiles shows up in Chapter 3. In Chapter 4 and 5, Barry's PTSD kicks in, resulting in vivid hallucinations. Of charred corpses of his lost loved ones and friends from the previous timeline, as well as the Iblis minion demons as the Paradooms. Chapter 13 meanwhile is basically in it's own league.
  • Deal with the Devil: Mephiles proposes one to Barry in Chapter 3, promising him the chance to go back and interrupt the events of Apokolips War to attempt in undoing the result of the war against Darkseid. Barry actually rejects the initial deal, but then is shown the fate that will befall this timeline, Mephiles having expected his reaction - however he still rejects to go back, instead however agreeing to let Mephiles help him get his powers back so he can "help" save the new timeline. While he's doing this because he doesn't want to intrude on the new lives of those he remembers as his friends, he has no idea who he's talking to at the moment. Mephiles also continuously tries to make one with Shadow, though the latter is not so easily deceived anymore.
  • Death Glare: After Shadow kills Kalibak and Grayven, he and Mephiles exchange these with one another.
  • Disney Villain Death: Averted, as Mephiles is quickly revealed to not be dead after his Palpatinian fall.
  • Electric Torture: In Chapter 4, Mephiles essentially does this to help Barry regain his powers.Rather than use an actual lightning bolt, Mephiles literally just has a chaos emerald shock Barry. Barry would have been left a charred, severely burned corpse if it wasn't for the fact he was a metahuman. Later on in Chapter 13, Mephiles does it to Shadow, Rouge, Omega, Big Barda, Oliver Queen and Jason Todd using his own hands - though thankfully for the anti-heroes they were spared when Raven re-enacts the ending of a certain movie.
  • Emerging from the Shadows: How Mephiles introduces himself to Barry in Chapter 3.
  • Evil Matriarch: Granny Goodness as to be expected of her; also the Queen of Bialya.
  • Fix Fic: Is an interesting example in that the story almost tricks you into thinking this was subverted back in Chapter 3, only for the antagonist to literally force it on all of the heroes in Chapter 16 ( by transporting them all to the part of the movie's timeline right before the invasion of Apokolips happened) whether he intended them to go through with it or not.
  • Hallucinations: Barry sees these in Chapter 4, and they reduce him to tears.Specifically, he begins hallucinating that the burned bodies of Crisis City's victims are the bodies of those who died in the Apokolips War timeline. He breaks when two of the hallucinations are of his nephews' corpses. He later sees hallucinations of the paradooms in Chapter 5, and initially runs away from them in fear - until he gets some motivation to do otherwise.
  • Heel–Face Turn: Barda in Chapter 13, though justified when she reveals her reasons behind the decision.
  • Heroic Sacrifice: The Raven of the new timeline qualifies for this. Already fatally wounded before but also electrocuted in the process of throwing Mephiles down, she succumbs to her wounds and melts in Shadow's arms, her action buying them enough time to prepare the scepter for their attempt in sealing him.
  • Hijacked by Ganon: Due to this being an adaptation of the Sonic 06 storyline, it was inevitable that Mephiles would hijack the main villain title from Eggman. He does it rather early too, literally the chapter right after Eggman shows up regardless of what site you read the fic on.
  • In Spite of a Nail: So the new timeline that was created has different names for it's months & oceans, completely different continent shapes, humans and anthropomorphic animals co-existing, said anthros being (allegedly) native to earth, and neither an Atlantis nor Themyscira (none that Barry could find, anyway). Yet somehow, Barry and Iris still exist, live in a city named "Central City" (albeit a different one), still retain the same jobs they normally do, and still have their immediate families barring the nephews & kids (who are just not born yet). It's even implied that Nora Allen is still dead in the same way she was originally. Seems like Speedsters might just be immune to the butterfly effect.
  • Laser-Guided Karma: Considering the DCAMU timeline from start to finish, Darkseid having created both Doomsday and the Paradooms, and then having the latter slaughter the friends and family of just about every hero; it's quite karmic to have a being that was essentially created to be the sequel to Doomsday literally kill both of his sons. While he (technically) watches.
  • Mind Manipulation: Mephiles seems to have taken several key DC characters from the old timeline and uses them as special soldiers of sorts, them being very effective at mentally effecting those who know them (just ask Barry). This process being referred to as enthrallment, they are left as essentially mindless, grayscale versions of themselves. The first to be freed was Wally West in Chapters 7-8, though he was joined by Oliver Queen in Chapter 11, and finally a certain Red Hood/Jason Todd at the tail end of Chapter 13. Currently Mephiles still is known to have Kara Zor-El (Supergirl), Dinah Lance (Black Canary) and M'gann M'orzz (Miss Martian) under his enthrallment.
  • Morton's Fork: It is revealed that in Apokolips War, Darkseid was basically running rampant across the universe due to the Lanterns and New Genesis fighting amongst each other (At least until Darkseid went to Oa, anyway) and being unable to impede him; Barda via her flashback essentially states he was indeed going to invade Earth anyway and purposely made himself appear vulnerable to the league in order to bait them into a trap on Apokolips. Which, as we know, ended up successful. But they would have potentially been screwed anyway as the implication is Darkseid would have attacked earth eventually regardless.
  • Neck Snap: How Aunt "Mairie" is removed from the mortal coil at the end of Chapter 6.
  • Nice Job Breaking It, Hero!: Barry's third flashpoint has managed, apparently, to create the Sonic timeline, and - so far at least - outside of himself, Iris and their immediate families, none of the people he recognizes from the DC lineup exist in this new timeline at all. In addition to that, Mephiles reveals that just like the previous two timelines, this one is going to end in complete disaster too. Of course, Mephiles is not at all telling Barry the full truth here.
  • Offscreen Moment of Awesome: As Barry is the initial focus character and doesn't have his powers at first, the first few portions of Sonic, Shadow & Silver's arcs occur entirely "offscreen", and starting from Crisis City onwards Barry is tagging along with Shadow and co. - resulting in Sonic & Silver's arcs remaining mostly offscreen. Though while Sonic gets a recap in Chapter 6 and is more than likely to get another one in the coming chapters, Silver appears to have most of his entire arc as offscreen.
  • Orifice Invasion: The Changelings, or more likely their queen lay their eggs inside the corpses of their victims in the deep recesses of their hive. That's all that really needs to be said.
  • Pintsized Powerhouse: When you remember that most of the anthropomorphic characters are within the 4 foot range in regards to their height, it certainly is amazing what they can accomplish in comparison to the Justice League of the previous timeline.
    • The biggest example is Shadow, though granted he is the "ultimate lifeform" created using the DNA from an avatar of Mephiles, who is half Darkseid. Shadow is not only capable to take on the members of the female furies with relative ease but also later kills Kalibak & Grayven, sons of Darkseid.
  • Poison Is Evil: In Chapter 8 it's revealed that while Mephiles' method of getting Barry his power's back did work, it left him with a terminal illness that turn his body into a chaos energy generator, eventually overloading it with energy until every last part of it shuts down one by one. Given that Mephiles is the main villain, it's very safe to assume and even assumed by Barry himself that this was done to him intentionally. Chapter 9 also as a result of this is a focused Find the Cure! mission.
  • Shell-Shocked Veteran: It is apparent in Chapter 4 and especially Chapter 5 that Barry is suffering from some form of Post-Traumatic Stress Disorder after the events of Justice League Dark: Apokolips War. Once he's transported to the future, the similarity of the environment to Apokolips gets to him and he begins to hallucinate. at first he hallucinates faceless bodies into being those of his friends and loved ones from the previous timeline, later he begins hallucinating Darkseid and his Paradooms.
  • Shout-Out: Has enough to warrant it's own sub-page.
  • Take That!:
    • Lady Mairghread and her cohorts Christina, Ernesto "Ernie" and Matteo "Matt" all take their first names from the writers & producers of Apokolips War. None of these characters are nice people, nor do they meet nice fates. In fact, the ways in which they die mirrors ways certain characters in Apokolips War perished.
    • The Paradooms are routinely insulted throughout the story at various intervals - the narration of the story itself remarks about how the creatures don't deserve existence, and later in Chapter 13 a certain big bad that is technically their own original creator remarks that they ended up being a failure while in the same breath stating making them serve as his elite military force is something he views as a mistake. Earlier in Chapter 5, there was also a particular moment where though it was an hallucination, the one who did in a certain kryptonian boy got particularly f'd up.
  • The Bus Came Back: This fic brings back several characters and concepts who either were left with ambiguous fates or mentioned yet never actually appeared during the course of the DCAMU films.
    • Komand'r, also known as Blackfire, appears in Chapter 13.
    • New Genesis is also mentioned in Chapter 13, the explanation for their absence in the old timeline being that they were at war with the Lantern corps for control over their rings - which allowed Darkseid to run rampant as shown in the movies. This in turn meant that emotions like fear (read: Sinestro) and rage (read: Atrocitus) received major boosts, with the red lanterns having at one point overpowered Metron, willingly giving the mobius chair to Darkseid. Which unintentionally led to a certain event in Apokolips War involving Batman. There is however no news on whether or not they exist or have an equivalent in the new timeline.
    • The Queen of Bialya who appears in Chapter 12 via flashback and in the flesh for 13 is revealed to be a surprise survival of a character from the old timeline. Namely Talia al Ghul. Considering she's queen of the Changelings though, it seems she's changed quite a lot since last we saw her.
  • The Chessmaster: Both how Mephiles views himself and how Team Dark (or at least Shadow) views him as. Between kidnapping and mind controlling key people from the previous timeline, to manipulating Silver to attempt killing Sonic & Barry to do the same with Shadow, to recruiting key figures to aid in his goal to reform into Solaris and establish a multiverse spanning "New Apokolips" Empire and the various things he's had his elite henchmen do to accomplish these goals it's clear his plan has a lot of pieces on the board so to speak.
  • The Wrongful Heir to the Throne:
    • Had it not been for Eggman and Metal Sonic, Lady Mairghread would have been this considering she already had the sheer corruption and behind-the-scenes rule down pat, as if already being the regent wasn't enough.
    • How Kalibak and Grayven view Shadow, even though he himself isn't interested in the throne at all. They view him as stealing their rightful place in their father's inner circle and grand plans, generating within them an envious desire to kill him so as to "restore" their positions. This desire of theirs causes both of their downfalls though.
  • Time Travel: Seeing as how the fic is titled "Flashpoint 2" and specifically crossovers with Sonic 06 in particular, time travel is an integral part of the plot here with multiple examples to choose from:
    • The premise itself: Due to Barry's previous escapades involving travelling through time, he somehow created the Sonic "timeline", and is just about as confused about it as half the readers probably are.
    • The villain, Mephiles, can just like in his original appearance travel through time seemingly at will - even calling it more precise and not as "sloppy" as creating a flashpoint, as he can evidently travel through time without completely reshaping the entire universe.
    • Chapters 4,5 and 7 take place 200 years in the future from the present time, while Chapter 10 takes place 10 years in the past; both of these visits happen due to time travel. The travel to the future was involuntarily caused by the villains while the travel to the past was voluntary on part of Shadow & Silver.
    • Whereas Apokolips War ended with current year being 2020, the new timeline's current year is 2006. It is unknown if this is because of the new timeline simply using a different dating system or if Barry really did wake up at a point 14 years too early.
  • Too Dumb to Live: Lady Mairghread and her cohorts, considering they would have caused the end of the world if Elise ever cried - and she came quite close at times, but as if that wasn't bad enough Mairie ultimately cancels her alliance with Eggman just because the latter wanted a refund. She does this while Eggman has her boat surrounded by his armed and armored robots. It does not end well for her.
  • Watching the Sunset: Barry and Iris do this at the end of Chapter 1
  • World of Weirdness: How Barry and the others such as Wally, Oliver and Jason view the new timeline, or at least after seeing the non-human co-inhabitants of earth in it for the first time. Those who are native the new timeline tend to see nothing out of the ordinary though.
  • You Can See That, Right?: Pretty much sums up Barry's reaction to seeing and later interacting with Sonic for the first time.

How well does it match the trope?
