Prologue/Episode 0: The Box
(Gremory Training House)
In many universes, the peerage of a certain red haired heiress would have been used only for 10 days of training before they fought against the heiress' fiance, who by then was an playboy asshole.
Yet in this universe, the heiress managed to keep her head cool thanks to her new pawn's, and secret developing crush, help and thus she instead got a month of training, which the fiance allowed, confident in his victory...and unaware of what would happen then.
Now the heiress, one Rias Gremory, and her allies, who consist of Issei Hyoudou, Kiba Yuuto, Akeno Himejima, Koneko Toujou, Gasper Vladli (who was allowed out of his sealed room by Sirchezs), and Asia Argento, were looking at a mysterious box with a note on top of it, which was in front of the house they would spent the month training...
"What is that box doing there, Buchou?" Asked Issei curious as he looked at it as Rias approached the box warily.
"Perhaps it's a gift from my Onii-san?" She wondered out loud before taking the note as she opened the box and everyone looked at it, revealing the content for everyone to see as she read the note aloud so that everyone could hear it:
"If anybody finds this package reading the note on this very moment, I don't have much time to explain. Whoever finds this package, I must tell you that it contains all the episodes that I and a friend have created, recorded and edited from a internet show that we posted on the internet and that we loved doing a lot. They will be sent to whoever and wherever I cannot predict. The world that I and my friend live on (or will once be) called Earth will eventually perish due to our ignorance in ignoring using alternate fuel sources for better environmental safeties. Now we pay the price. The end is coming soon and I dreadfully predict at this very moment. I wish for my favorite series from an internet show will forever live on being watched. Please take good care of them. If you don't believe me and think this is some kind of prank, I don't blame you. Who else would believe me? May we all shall rest in peace when our time have come.
Atte.
Wizard and Boomstick
P.S, I want you to skip episode 14 and get rid of it. Even I questioned why we crated it before we recorded it and placed it in the box. It's a lame episode, trust me. But if you want to do so, be my guest."
They all stood silent as the message of the note settled in before their eyes widened as Asia cried, because somewhere out there, a world filled with millions of life, several innocent as well, had died out, leaving only this box with the DVDs behind...
"T-That has to be a j-joke, r-right Buchou?!" Issei asked perturbed as he tried to comfort Asia, Gasper and Koneko, the latter who was shaken up.
"I-I wish it was...but this isn't my Onii-san's writing..." Confessed Rias as she managed to recover herself alongside everyone, sans Asia who was still shaken up. "So what you think we should do with these videos?"
"I think we should watch them in honor of those people's memories..." Kiba said somberly as everyone nodded and quickly took the box inside before preparing the DVD player, with their training plans forgotten for the moment.
With that, all members of the Gremory Peerage were now seated on the couch in front of a TV as Issei put the first episode on the DVD player that now would be used to see the series of another world.
Then they saw a black screen from which several words in red appeared:
The Rules (unwritten and official) of a Death Battle are:
The warriors can only know of each other if they do know each other in canon in both official universes. Otherwise, they cannot know each other's movesets. Even if they do know of each other in canon, no one is allowed to prepare for the fight.
Characters are allowed to know each other's names or their internet rivalry but can't know each other's physical traits.
To prevent fighters from exploiting weaknesses of others for a cheap victory, a character's weaknesses normally only come into play if the enemy can find a way to detect a weakness (like x-ray vision) or if there is a specific reason why it cannot be exploited. Other than that, if a combatant survives a match long enough, they may discover a way to counter the fighting style of their opponent.
A battle has to end with the loser dying, or at least "dead" as far as physical forms are concerned (for example, being reduced to little more than a ghost, or gods and similar characters left with no working mortal avatar to continue fighting with).
Pacifist warriors will not have their peaceful nature interrupt the fight, and both combatants will have any personality restraints from killing removed (such as two opponents fighting each other to the death when they would not do so otherwise). However, if their traditional arsenal uses nonlethal weapons, they cannot change it. They can only use lethal weapons if they have them as part of their regular arsenal.
All other traits will be represented with accuracy based on the warrior's canon universes (as stated, expanded universes are only allowed to be mentioned if they do not conflict with the original canon). All consistent and canon sources available during the time of the episode's release will be examined by the hosts. Characters with multiple incarnations, such as Link, Spider-Man, Deadpool, and Godzilla, will be composites combining the best aspects of their various incarnations, unless said incarnation is drastically different from other incarnations. If a specific incarnation of a character is chosen, the canon used will most likely be the most popular depiction (e.g. G1 Starscream, G4 Rainbow Dash, and post-Crisis Batman). The research will avoid biases.
B. If one warrior is allowed abilities from a non-canon source, the other warrior must be allowed to use their own non-canon sources as well.
C. Also, if a certain depiction of the warrior has them ridiculously overpowered or inconsistent (like the live-action films), or powers that would be difficult to examine logically, then it will not be used.
D. Not every weapon owned by the warriors in every canon will be used. Instead, only the ones they are commonly using or their best or most iconic weapons (e.g. two opponents were equipped with their best armor and magic only if they have too many to show at once) will be used.
E. If a warrior originated from foreign media, the American dub will not be used if it contradicts the original source in any way.
F. A piece of media that claims to be canon but clearly isn't will be avoided. For instance, the 1998 Godzilla film is not used to measure Godzilla's abilities because, as was shown in Godzilla Final Wars, the monster Zilla is clearly not Godzilla. Also alternate forms of media might be avoided, like Shao Khan's film depiction (where he can transform into a hydra, which won't be used here).
G. Because the warriors are examined by their latest depiction, they cannot use abilities that they lost in their past.
H. Claims made by fans will only be considered canon if the official franchise or character from an official source recognizes it, as seen by Chuck Norris recognizing and acknowledging fan claims in his book "The Official Chuck Norris Fact Book: 101 of Chuck's Favorite Facts and Stories".
To get as many common abilities as possible, the warrior will be shown at their latest depictions or their oldest age as an active warrior. However future canon will be avoided if it unbalances the fight some characters like Superman will gain more power in the future in DC One Million while some characters like Batman will grow old and weak like in The Dark Knight Returns. In the case of 2D end battles, a character's depiction in the end fight is limited by what sprites are available for them, such as Harry Potter having their appearances as children despite using abilities and weapons obtained as adults, and Nightmare appearing in his Soul Calibur IV form.
Summoning other combatants is not allowed unless the battle calls for it (like how two commanders fought with their armies). Unless the battle asks for multiple characters for each side, the combatants must fight alone, even if they are used to fighting with a partner (like how a summon isn't allowed to have their summoner command it on battle).
B. The only exception is if the fighter uses a creature for an attack that can reasonably be replaced by a non-combatant projectile (like how Peach can summon a sheep that doesn't do anything but fly at the opponent and put them to sleep with contact, or the Goomba firing Mini-Goombas) or when the act would fall under using the environment to their advantage (like how Batman can summon bats from the surrounding area with his gadgets), but the fighter cannot be dependent on these creatures and, in cases of summoning as an attack, the creatures cannot act on their own (like how two opponents were not allowed to use summons or fairies because the summons attack on their own once summoned and the fairies are sentient beings making a decision to help their summoner once he-she runs out of vitality).
C. Another exception is a Doombot or fake clones, as seen with Wily and Dr. Doom. However this clone cannot fight alongside the original simultaneously as it would mean the opponent would be outnumbered.
The terrain chosen in the fight will either be a terrain from the fighters' franchises (like Superman's Metropolis or Goku's mountainous terrain) or would be a location that both warriors are experienced in (like Batman and Spider-Man fighting at night in a city). The area itself however doesn't matter nor play any role in determining the outcome of the battle, and even the entire battle itself is just a visual representation of the researchers' conclusions. The environment only becomes important if a character's skills use it, like with Leonardo hiding in the shadows or Chun-Li/Mai wall-jumping.
The fight at the end of the episode is not what determines the victor in battle. It is nothing more than a fun little dramatization showcasing most if not all of the research displayed beforehand of the combatants in action. The winners are determined before the battle through quasi-scientific analysis of their abilities, and the character with the objectively better abilities will win.
"This is interesting..." Akeno spoke in an amused tone as she couldn't wait to see who would fight to the death. "Who you think it's going to fight there~?"
"It seems we're about to find out..." Koneko said simply as the first episode finished charging.
