[[caption-width-right:347:"I'll be meeting them finally tonight."]]

An animated web original by Xionico that began on Madnessday 2007 on [[http://www.newgrounds.com/ newgrounds.com]], a day dedicated to celebrating Matt Jolly's, AKA "Krinkels" original series, ''WebAnimation/MadnessCombat''. Xionic Madness uses the same basic design; i.e., cross-faced people with disembodied hands and feet, (other than [[NonStandardCharacterDesign Kary-08]] that is) but uses its own style of action. It's also notable in that the series has voice acting in later episodes, in contrast to its inspiration.

The story follows our [[HollywoodCyborg cyborg]] [[AntiHero heroes]] (other than [[RunningGag Kary-08]], who is entirely robotic) over on the right. Going left to right, Xero, the blue guy, is the hot blooded blade handler. Omega, the red one, is the leader of the group with a fancy for guns. Kary-08, the green girl, is the childish energy wielder. Askad, the yellow fellow, is the brainy explosive user. The four of them are sent on a mission (that is considered a suicide run) by the company that created them. Their objective: wreak as much havoc on a rival company that has been prying into their secrets as they can. Needless to say, they do just that.

They slaughter everything they see without a single thought. However, the mission retaliates by increasing its difficulty as the four progressively go deeper into it. In addition, they encounter XV, an experimental weapon developed by the company they are wreaking, which just so happens to be on the top of their "things to kill" list. They end up having to [[LetsSplitUpGang split up]], and deal with the trials alone. (Though this still doesn't stop them from destroying everything.) Through all the difficulties, they manage to escape just before the [[TimeBomb N8]] [[RaceAgainsttheClock goes off]].

And although they completed their mission, the true battle [[ItHasOnlyJustBegun has only just begun]].
----
!!Tropes include:
* AbnormalAmmo: At one point, Omega uses his own blood as miniature missiles using a syringe-like gun.
* ActionGirl: Kary-08 can hold her own better than any of the others, in fact, Omega even admits that she could kill him in a fight.
* AllThereInTheManual: Some of the episodes have extra features that contain information on the characters, weapons, and backstory.
* AnAxeToGrind: In the later half of the series, Xero acquires a bladed weapon that resembles an axe. However, it's primary function is to use the blood it absorbs as an [[LaserBlade energy blade]].
* AndTheAdventureContinues: [[spoiler:TheStinger shows Enid, Xero's apprentice, having survived the BolivianArmyEnding, taking off before the screen cuts to black]].
* [[AntiHero Anti-Heroes]]: Although they are the protagonists, they are all ruthless killers.
* AppliedPhlebotinum: Many of their weapons have bizarre mechanics behind them; i.e., using blood as projectiles, converting human mass into pure energy, and cutting people with wind.
* ArtEvolution: Although subtle, the style and animation quality does increase.
* ArtShift: In the scene showing the events that occur directly after the initial mission, there is a noticeable difference in art and animation style.
* BackFromTheDead: [[spoiler:Askad]] comes back as a robot to save the others just in time.
* BadBoss: The Overseer. [[spoiler:He sends Bolverk Squad on a suicide mission to BIO INT so he can replace them with robotic duplicates and when Omega and Xero survive, he has them imprisoned]].
** In Xionic Madness 3, [[spoiler:he sends dozens of soldiers to their deaths against Omega and Xero just so he can collect battle data for his robotic versions of Omega and Xero]].
* {{Badass}}: All four of the main characters display incredibly high levels of badassery.
* BadassCrew: Bolverk Squad. And later, Omicron Squad as well.
* BadassNormal: Before Omega and Xero became cyborgs, they apparently were able to keep up with the cyborgs as normal humans.
** Omicron Squad, despite not having any PoweredArmor, proves that they can hold their own against an army of zombies just as good as Omega and Xero.
* BashBrothers: Omega and Xero later in the series.
* {{BFG}}: In Omega's arsenal of guns, there are of course at least a handful of these.
* {{BFS}}: In the second half of their initial mission, Xero acquires a massive blade that literally cleaves people in half.
* BigDamnHero: [[spoiler:Askad]] arrives to save the guys right before they are about to be killed.
** Omicron Squad also pull one of these, arriving to save Omega and Xero just as their about to be eaten by zombies.
* BloodSplatteredWarrior: By the last third of part 3. Xero is practically ''dripping'' blood, only most of it isn't his.
* BottomlessMagazines: The squad may have to reload frequently, but they are not going to run out of ammo anytime soon. Their support network can send them more ammunition from an orbiting satellite.
* {{Body Horror}}: Anything infected with the XV virus, and XV itself, grow such things.
* BolivianArmyEnding: [[spoiler:Xero finally]] "dies in the heat of a glorious battle" after everyone else had already bit the dust.
* TheCameo: Hank from the original Madness Combat makes an appearance to body slam a mook.
** Also, he, along with Jebus and Tricky, appear on a computer screen during the first mission.
** In the final episode, [[spoiler:Kary-08]] summmons something that highly resembles Demon Tricky.
* CharacterDevelopment: With every passing episodes, more information is revealed about the characters.
* ChekhovsGun: [[spoiler:The XV virus]], which was introduced in the first mission, makes one final appearance before the ends to help defeat the final boss. [[spoiler:But it also makes Xero kill Omega]] and, in the end, [[spoiler: a dying Xero [[BolivianArmyEnding seeks death against the group hunting him "In the heat of a glorious fight"]]]].
* ChekhovsBoomerang: The loner knives. First seen when [[spoiler: Askad commits suicide to kill off the XV drones surrounding him, ]] they're used again [[spoiler: against the XV when it duplicates Omega,]] and again in three [[spoiler: against the character's [[RobotMe robot copies]]]], Before finally being used [[spoiler: by Kary to destroy herself and deny XV!Omgea the pleasure.]]
* ColorCodedCharacters: The four protagonists each have their own color scheme, if that hasn't already been figured out.
* CommLinks: The team seems to have this built into their bodies so that they can keep in touch at any time.
* CoolHelmet: Omega is almost always seen sporting one of these.
* CoolMask: Xero also always has his headgear on.
* CoolSword: Xero's entire arsenal pretty much consists of these.
* CorporateWarfare: The first three episodes deal with the suicide mission against Bio Int. Corporation. The team's employer just wants them to destroy the top-secret project XV, which is mentioned to be derived from alien technology. Then a unnamed third party sends a commando unit to steal XV for them dead or alive. And a throwaway line by Omega states that Bio Int. wanted to sue their employer for human experimentation. While nothing states that this is considered normal for the setting, it certainly makes for an interesting night.
* CrazyPrepared: [[spoiler:Askad anticipated that the organization they work for would betray them at some point, so he prepared a fake upgrade for Kary to restrict her powers and a robotic duplicate of himself, in case he died before warning Omega and Xero]].
* CuteAndPsycho: The first thing that happens in the series is Kary going [[Franchise/{{ANightmareOnElmStreet}} Freddy Krueger]] on a mook. [[spoiler:Then she takes it up several notches when she turns against the team.]]
* CyanidePill: The loner knives, with the added bonus of [[SuicideAttack taking out the surrounding area in the resulting explosion]].
** They're promptly exploited [[spoiler: against XV and the robot doubles, [[TheAssimilator due to]] [[EvilKnockoff all three of them having]] enough similarity to our anti-heroes that the knives still activate against them.]]
* DeflectorShields: Kary can use her energy abilities to create force fields that are practically impenetrable.
** Apparently, Omega can create force fields as well.
* EliteMook: Some of the mooks are of significantly higher rank than others. However, this doesn't make them any less susceptible to being effortlessly killed.
* {{EMP}}: Askad uses this against [[spoiler:Kary after he comes back as a robot]] in order to give his allies a fighting chance.
* FaceHeelTurn: By the end of the first mission, it is revealed that [[spoiler:Kary has been working against the team]] for some time now, and [[spoiler:she attacks them]] while they are returning to base.
* FlippingTheBird: Xero does this frequently from part 3 onwards. One notable instance is him defiantly flipping [[spoiler:Kary]] off during the final battle as [[spoiler:she's]] about to blast him.
* GambitRoulette: Apparently, [[spoiler: someone planned on Askad dying. And planned Kary-08's betrayal. AND planned Omega getting infected by the XV virus]].
* GatlingGood: Omega uses a Gatling gun to battle against the BigBad during the first mission.
** Later on, there are ball-like robots with gatling guns attached to them.
* GiantMook: While battling an army of undead soldiers, Omega and Xero face what seem to be zombies that mutated into behemoths.
* GogglesDoNothing: Kary always has a pair of goggles resting on her head, but she never actually puts them on.
* GoneHorriblyRight: The whole team becomes (thanks to extensive cybernetic modification, prototype weaponry, and training) nigh-unkillable to [[spoiler: their former employer and would-be master]].
* {{Gorn}}: Well it was based on ''WebAnimation/MadnessCombat''.
* GunFu: Naturally, Omega displays his gun fu expertise all throughout the series.
* GunsAkimbo: Once again, Omega sometimes enjoys having a firearm in each hand.
* HeroicSacrifice: [[spoiler:Askad]] does this twice. [[spoiler:First he self-destructs in an attempt to kill some XV-infected entites]]. [[spoiler:He comes back as a robot and self-destructs again to take out Kary's shield and give Omega and Xero a chance against her]].
** [[spoiler:Omicron Squad]] pulls one as well, [[spoiler: sacrificing themselves to destroy the building Omega is holding up]].
** [[spoiler:Omega]] sort of pulls one in the final episode by [[spoiler:allowing Xero to kill him to prevent the XV virus from fully taking over his body]].
* HoistByHisOwnPetard: As applied to [[spoiler:the [[BigBad Overseer]]]]. [[spoiler:He decided that the team was going to turn on him eventually, so he sent them on the mission to Bio Int, hoping they would be killed. If anyone on the team got back alive, he would have Kary kill the survivors. However, the only one who died was Askad, the one who kept her sane. Without Askad to give her regular checkups, Kary betrays and kills the Overseer]].
* HumanoidAbomination: XV usually takes on monstrous forms, but it sometimes morphs into deformed humanoids.
* HumansAreBastards: Kary was created solely to kill people from the day she was "born". Her power source can only function off of the bioelectricity she sucks up from those she kills. She notes this later on in the series.
* HyperspaceArsenal: Omega and Zero are equipped with this thanks to their employer's technology. It involves a satellite teleporting weapons and ammo to them on demand.
* ImaginationBasedSuperpower: Kary can use the energy she collects however she wants. Though she mostly uses it in the form of projectiles or blades (or just converting living humans into raw energy.)
* IronicEcho: After the fight [[spoiler: with their robot duplicates]] ends in a massive explosion. Notable because this was a [[ThrowItIn formatting error that just happened to fit perfectly.]]
--->'''Xero:''' "Look, if you want to make this one-on-one, just say so..."
* JerkWithAHeartOfGold: Xero constantly argues with Omega, and swears at practically everything, but he would rush into the face of danger to save a companion without a second thought.
* JetPack: Xero receives an upgrade that gives him rocket boots. Unfortunately, he isn't allowed to keep them.
* KatanasAreJustBetter: Xero uses katanas in the beginning of the series. Though his arsenal later on consists of more unique weapons.
* KillEmAll: [[spoiler:By the end of the series, basically every character with a name is dead. Xero manages to live to the epilogue, though.]]
* TheManBehindTheMan: [[spoiler:The final episode of the series reveals that the Overseer was apparently being manipulated by someone even more shifty]].
* MechaMooks: Full metal robots soon get sent to face against Omega and Xero. Though they only last a little longer than the humans.
* MercyKill: [[spoiler:Xero is forced to do this to Omega when he's infected by XV.]]
* {{Mooks}}: The guys constantly have wave after wave of nameless men thrown at them.
* MoreDakka: Omega's preferred method for dealing with enemies.
* NerdGlasses: Askad, the team SmartGuy/explosives guy always has his yellow glasses on.
* {{Ninja}}: Xero is a dead ringer. He is built for speed and accuracy, [[TeleportSpam teleports frequently]], and has semi-traditional accessories.
* OneWingedAngel: In an attempt to make sure Omega and Xero absolutely die, [[spoiler:Kary puts on a power mask]] and turns into one of these.
* RevolversAreJustBetter: When Omega's favorite handgun, Joy, is rendered unusable, he requests for its replacement to be built as a revolver.
* PistolWhipping: Occasionally, Omega has to give his trigger finger a rest, and go melee.
* PosthumousNarration: All of the bios in Xionic Madness 3 are narrated by [[spoiler:Askad]].
* PsychoRangers: When Omega and Xero are making their escape at a train station, they are pitted against robotic copies of themselves.
* PoweredArmor: Omega and Xero can usually be found wearing one.
* RedOniBlueOni: Ironic in that Omega (colored red) is the blue oni, and Xero (colored blue) is the red oni.
* {{Retcon}}: Askad's original story, in which he was an explosives maniac who got betrayed by his allies, was changed to be more deep and meaningful.
** Though given the fact that his original character bio was "written" by [[spoiler:the company he worked for, which was forcing him to work for it, and eventually had him killed,]] it could be that [[spoiler:his original story was fabricated]].
* RuleOfCool: Many of the weapons seem to be based around this.
** Frankly, the series in general seems to be based around this.
* ScarfofAsskicking: Xero sports one from episode 3 onward.
* SeeYouInHell:
-->'''Xero:''' See you in hell..."
-->'''[[spoiler:Omega]]:''' *chuckle* We'll all be waiting for you...
* ShoutOut: There is a multitude of shout outs that the animator added.
** Omega and Xero share a certain battle cry: [[VideoGame/GuiltyGear "Heaven or Hell? Let's Rock!"]]
* SirSwearsALot: '''Xero'''. It's probably easier to list the lines he gets that ''don't'' contain any sort of profanity.
* SuddenlyVoiced: All of the characters in series become voiced from episode 3 onward.
* SwordsAkimbo: With a sword in each hand, Xero can kill things with twice the efficiency.
* ThrowingYourSwordAlwaysWorks: During the later half of the first mission, Xero throws his {{BFS}} at a zombie.
** During the final battle, Xero throws the pole he's been using as a blunt weapon at [[ItMakesSenseInContext a giant, flaming monster clown]].
* TookALevelInBadass: During the first mission, [[spoiler:Askad]] could be considered the weakest. But during the final fight, [[spoiler:his robot form is able to fight on par with Kary.]]
* TreacherousQuestgiver: [[spoiler:The Overseer]].
* UnorthodoxReload: Several of Omega's more advanced weapons. For example, his sniper rifle only needs one magazine. This is because whenever he removes it from the rifle, more seem to teleport into it as he reinserts it.
* WeakButSkilled: Askad considerably weaker than the rest, but is especially intelligent, as well as having explosives knowledge.[[spoiler: His robotic duplicate admits to being weaker than Kary, but has the ability to render her normal defenses useless, as well as being able to anticipate most of her movements]].
* WithGreatPowerComesGreatInsanity: Kary is the strongest of the four, but she needs to have regular check ups in order to keep her personality under control. [[spoiler:So when Askad, the one who gives her the check ups, dies, Kary ends up going insane.]]
* ZombieApocalypse: [[spoiler:In episode 4 part 1, Kary-08 revives all of the mooks Omega and Xero had faced thus far, as zombies]].
