A/N - Invader Zim belonged to Jhonen Vasquez and Richard Steven, but all of the OCs involved belongs to me.
Dib and Zim stared in horror at Lily. The stoic and aloof girl with a good heart... is gone... now, she's the weapon of destruction who's intent to kill...
"Wha...what the hell do you do to her?!" Dib shouted at Ate.
"I simply reminded her, what she truly is, that's all," Ate replied, "Are you angry that I used your little sister as a template?"
"Grr... why, you bitch!" Dib shouted as he charges up an electric ball from his hand, but Lily puts her hand up and shoots a laser beam at the ball, and then to a nearby building, causing a massive amount of damage to it. "Wha... what...what the... hell...?"
"... Mission?" Lily asked in a robotic tone.
"Just go to the Abyss of Hell," Ate told her.
"Understood..." Lily nods as she teleported out of the area.
"Shit!" Dib swore.
"I go after Lily, you focus on Ate!" Zim told him off.
"Why?" Dib asked, "Shouldn't I be the one go after Lily? Considering she's technically my sister,"
"Dib-stink! Zim has his reasons, but just don't question it!" Zim said as he runs away to go after Lily.
"Well... I was hoping to fight against Zim, but this is good too," Ate said as Dib creates another electric ball and throws it at the goddess, which she deflects it. "Is that all you got?"
"Grr..." Dib growled as he rushes to her.
Ate steps back and ducks down as Dib throws his punch at her, where she puts her palm to his stomach, but he quickly backs away and punches the ground, which electricity aims at her underground. Ate jumps up into the air and wraps Dib with her whip.
"Shit! I'm screwed!" Dib thought.
"Sorry Dib... But I have to do this..." Ate apologised as she lands on the ground and her whip slowly starts to glow while Dib is struggling to get out, "In order to kill the people who ruined my life... as well as obtaining that box no matter what... even if it means hurting my loved ones... sorry..."
The whip glows bright and Dib screams while his eyes start glowing purple.
(Vision)
"Where... where am I...?" Dib asked as he sees his younger self arguing with Gaz, "Oh no... Any... anything but that..."
"Seriously?! You're still trying to expose Zim!" Gaz asked him harshly, "Do you know what day it is?!"
"Yes, I do!" The younger Dib replied angrily, "But, I'm very busy right now!"
"You're always busy with your stupid paranormal stuff!" Gaz complained, "Even when this is our dad's only day off!"
"Gaz... as if you're any different!" The younger Dib pointed out, "You're always on your stupid video games!"
"..." Gaz glared at her older brother as she grabbed his arm and kicked it with her knee.
"Ahhhhhh!" The younger Dib screamed in pain while Gaz walked away, "I-I hate you, Gaz!"
Gaz stopped for a moment and said, "... I always hated you... you're just a nuisance and annoying... in fact, I always wished I never had a brother, so... do me a favour and go to hell..."
"..." the younger Dib is speechless as his sister walked away.
"A... no... that... I..." The present Dib starts stuttering... as he remembers that was the last time he sees his sister...
(Fast forward)
"Wha-What the?!" Dib shouted... as he sees his father and Ate facing each other in a dark alleyway, "What... what is..."
"So... we meet again... Ate..." Membrane said as Ate takes off her hood, showing her true appearance where her skin is much paler, no make-up, the same eyes colour and has short, dark purple hair that makes her resemble a bit like Gaz.
"Membrane... do you know why I'm here?" Ate asked him.
"Yes... and the answer is no," Membrane replied.
"What?! Why not?" Ate asked harshly, "You do realised once we get Pandora's box and kill the gods, you can have ultimate knowledge and I get my revenge, simple as that!"
"What about our kids that we artificially created by cloning, huh?!" Membrane asked harshly, "That we should sacrifice them!?"
"You do realised we created them for the sole purpose of making the second Shadow Dragon, right?" Ate asked them. "Where Dib is the Brain, Gaz is the Heart and we're supposed to make the Body, until you run off with our creations,"
"... I know... but after realising they developed their own personalities... I... I just couldn't..." Membrane said. "Which is why I sealed their dragon blood abilities away by placing a special type of chip in their brain that blocks their powers from ever being used and so they never discovered their true identity,"
"Even after you traumatised your son and transforming your wife into a killing machine," Ate pointed out, "That's ironically cruel, which is saying a lot, coming from me,"
("... Wait... I... I'm a clone who's meant to be the brains of the Shadow Dragon?!") Dib thought in shock, ("And Ate is technically my mum?!")
"... That's why I been so focused on my job... to redeem myself after the suffering I caused in the past," Membrane told her.
"... I see, but that wouldn't stop me from getting my revenge..." Ate said, "So, if you're not giving them to me, I have no choice... but..."
Ate gulped and said, "To kill you,"
"..." Membrane didn't say anything until he heard someone.
"Oi! Dad!" Gaz called out as she enters while playing her video game and not paying much attention, "What are you doing?"
"Gaz! Get out of- Gah!" Membrane shouted until he coughed up some blood and looks down to see his stomach was stabbed by her bladed whip.
"Dad?" Gaz looked up and immediately dropped her console by accident as she opened her eyes and turned pale as she sees her father fell to the ground... dead while the woman quickly grabbed hold of the little girl, which caused her to scream and started crying, "Hey! Let me go! Let me go! Somebody! S-Save me! Please! Save me!"
Ate stayed quiet as her whip glowed, causing Gaz to screamed in agony, her eyes flowed purple and fell unconscious.
Dib becomes speechless as he witnessed Ate kidnapped Gaz by putting her in the large, grey bag, which he sees... Zim is inside it as well and she left the scene.
"... I... No... I... that's... Ahhhhhhh!" Dib screamed as he kneels down and starts crying.
(Vision ends)
Dib falls unconscious as Ate unwraps him and sighs.
"... Sorry Dib... but this is... simple fate," Ate apologised to him, "You can't escape your destiny... nobody can... not even me..."
Ate teleports out of the area.
(In the Abyss of Hell)
Dark Artemis teleports to the same area with the Abyss of Hell. She looks down and slowly starts floating down to the Abyss itself... until a black and white slash attack aimed at her and she blocks it with a purple shield.
She turns her head and sees Artemisia with her sword out.
"... Analysis target..." Artemis said as her eyes starts scanning the sliver knight, "Real name; Unknown. Alias; Artemisia, leader of the Six Mirages and the Sliver Knight. Known weapon; Paradox blade, one of the seven deadly weapons that allow time travel. Objective: Kill..."
Artemis summons large, yellow glowing arrows and throws it at her, who she slashes down; creating a black and white portal that swallows up the arrows. The portal disappears and Artemisia creates another portal, which shoots back the arrows at her.
Artemis creates a shield, which absorbs all of the arrows.
"Shit... if this keeps going, I might use up all my energy and she'll cut me down..." Artemisia thought as she points her sword at her, "I guess I have no choice,"
Artemisia takes a deep breath and says, "I... am the embodiment of justice..."
Her sword and body starts glowing while Artemis starts shooting out light arrows at her, which is blocks out the attacks with a white shield around her.
"I am send to destroy all the evils mankind have created... I will abolish any evildoer on my path of righteous..." Artemisia said as the shield is put down, she stops glowing, but the sword is still glowing, "Now... meet your end, monster!"
(Meanwhile with Zim)
Zim runs downstairs and suddenly, he felt a small earthquake.
"Ahh!" Zim screamed as he wobbles a bit, but manages to get his balance. "... What... the hell was that...?"
Zim looks around and remembers something, "Ah! That Abyss! I almost forgot about it!"
Zim rushes to the entrance that leads to the Abyss.
"I'm gonna save you Lily! Even if I'm gonna have to sacrifice myself to do it!
Couple of minutes later, Zim arrives at the area while Ate teleports into the area from behind the scenes.
"Well... that escalated quickly..." Ate muttered as she witnesses Artemisia and Dark Artemis clashing with everything they got.
The silver knight steps on a wall and does a three wave slashes at her while she jumps to the floor. Artemis creates a shield to block of her attacks, and then strikes her with dozen of light arrows.
"Crap!" Artemisia swore as the arrows are flying towards her.
"Artemisia!" Zim shouted as he jumps in front of her and created a shield of dark magic to block off her attacks.
"... Zim... Wait!" Artemisia said, "Where's Dib?!"
"He's up, going against Ate!" Zim told her.
"... You idiot!" Artemisia shouted at him, "You know he's only human, right? Even with one of the seven deadly weapons, he has no chance against a goddess!"
"He's artificial demigod!" Zim told her off, causing her to be speechless, "So, he should be fine!"
"..." Artemisia was speechless, never knowing who Dib really was.
Artemis stopped her attacks while Zim puts down his shield.
"Snap out of it, Lily!" Zim shouted at her.
"... I am not Lily... I am Dark Artemis..." Artemis told him, "The world is nothing but a shell of hatred... racism, bullying, selfishness, sexism and much more... the only solution to solve them is to punish mankind by destroying them."
"No, it's not!" Zim shouted at her again, "And you're not Artemis, you're Lily Abernathy! The annoying lieutenant that everybody gives a crap about!"
"Die!" Artemis shouted as she throws more arrows at the two while Ate watches with a blank expression.
"... Too bad they don't know that the only way to stop Lily..." Ate thought as she clenches her fist, "Is to... kill her..."
More and more blasts are happening in the battle as Artemis is continuously throwing light arrows at them while Zim is shielding with dark magic, which is slowly cracking due to the amount of power.
"Shit... if we don't do something fast... we're dead!" Zim thought as he looks at his left arm and gulps, "Oh boy... here I go..." "Hey, Artemisia! I have an idea!"
"Huh?" Artemisia blurted out, "Knowing you, it would be a bad idea,"
"Just listen to me or we'll die!" Zim told her off as his shield is slowly, but surely cracking away.
"...Fine, what is it?" Artemisia asked.
"Just create a portal below me and distract her for Zim, got it!?" Zim told her.
"...Fine," Artemisia agreed, "If this plan fails, it's gonna be your fault, understood?"
"Yes, I am fully aware of that!" Zim replied, "Now do it!"
Artemisia nods and hits her blade to the ground, creating a portal underneath the irken and he jumps in while the knight rolls over before the attacks hits the ground and destroying that spot.
Artemis continues shooting many powerful arrows at her and completely distracted. The portal opens up as he jumps out and tackles her from behind.
"A-Ahh!" Artemis screamed in shock as she and Zim smash to the ground.
She tries to get up, but Zim suddenly grabs her with his right hand by the neck and put his left palm on her face.
"Le-Let go of me at once!" Artemis screamed at him, "Humanity must be destroyed! They caused nothing, but despair to the world!"
"Shut up!" Zim told her off, "... Lily... I know we have our differences in the past... but... despite how shitty the Earth is, there are good humans... you said despair, right? Well... you're the biggest idiot I have met!"
"... Wha-I... I do not understand..."
"See?! If you saw the evil side of mankind, then you must have seen the good in them!" Zim shouted at her, then calms down, "... I looked down on humanity as stupid and useless beings that should be enslaved... but now... after being saved and raised by a human mother as well as travelling many places... I learnt... humanity isn't as stupid as I thought..."
"Y-you're lying!" Artemis shouted at him.
"Shut up!" Zim shouted at her again, "Have you forgotten about your loved ones? Have you forgotten who you really are?! You're not a weapon of destruction... you're Lily Abernathy... a human girl... even if you're actually not... I know, deep down... you are..."
Suddenly, his left hand starts to glow, which Artemis grabs his hand and tries to pull away, but Zim is too strong for her to handle physically.
"... Curse breaker 999... Wake up, Lily!" Zim shouted at her, "It's time to shape your own fate, Abernathy!"
The powerful burst of dark magic happens, causing Artemis to scream in agony while Zim's left hand is cracking... along with his entire arm as he grits his teeth and endure the pain he's suffering.
Suddenly, his arm completely shattered into pieces and Artemis' eyes turns from bleak yellow to bright blue as Artemis is gone... and Lily is back...
"...Huh...?" Lily muttered as she looks and sees Zim... with his left arm completely gone, "... Z-Zim!?"
"... F... finally... I... you're... back..." Zim muttered weakly with a faint smile, "I... I'm glad..."
Zim fell unconscious and fell to her lap, much to Lily's shock.
"... Z... Zim!" Lily cried as... for the second time in her entire time, she starts tearing up, "Z-Zim! W-wake up! P-please!"
