Timeline Troubles

You and Ink stopped at a snowdin that looked kind of grim "What's this place...Is it the Errortale?" She shook her head "No...This is Insanitytale" Suddenly a gaster blaster came at you from behind. You turned and blocked with the frying pan "Sans...?" It was sans with blood down her body as she held the skull of papyrus in her hand "hehe...HAHAHA!" He threw more bones towards you and Ink. You summoned your frying pan and broke through it. You summoned the orange soul as your fist glowed orange. You punched Insansity across the face launching him back "We must save our energy for the fight with Error!" You nodded "Open the portal. I'll hold him off" You raised your hands into the air "Let's...GO!" You slammed your hands into the ground and a green shield raised up "Ok...That'll hold em off" Insansity stabbed right through it and grabbed you by the neck "Or...Not" You pushed a purple book in his face that had words break out and stab his face causing him to fall back "It's open!" You backed up towards Ink and entered the portal

ErROrRtALe

You and Ink stood in the judgement hall "Judgement hall" Ink looked around as she saw Error glitch further down the hall "This is your judgement hall...Where I judge your love and EXP...every sans does it...Seems like you have no EXP or LOVE yet you are extremely powerful" You moved a bit closer "Look...Sans...We don't need to fight. Just listen to my voice" Error sans sighed "God people like you. I hate the most. Let's just get going"

Your right eye glowed yellow as you blocked the huge knife coming from behind and threw her backwards. You shot 3 bullets at Cross sans and he blocked them all "What a knife..."

The area turned black and white. You entered battle

(Y/N) and Ink, Keeper of souls and creator of worlds

Error and Cross, Destroyer of worlds and crusher of souls.

You looked at Ink "No messing around. Let's do this" The souls surrounded you. In a flash of light, you entered your god form. You rushed at Error as she grabbed you with wires but you span around causing her to spin. You summoned a gun and shot her in the chest to launch her back. Cross caught her and charged at you. You summoned a sword and blocked her knife "Agh..." She kicked you upwards but you flew straight down cutting through her but she dodged and you accidentally cut her jacket. 

You fell to the floor and span around catching yourself with your sword. Error rushed towards you but Ink blocked and threw her back "You take cross!" You and Ink nodded as you summoned a second sword "Come at me" "Your funeral" You and Cross clashed. You raised your other sword and swung down on her but she turned and kicked you across the face but you sliced her back and went in for a stab but she blocked it with her knife and you slid past. She caught you and threw you to the ground but you managed to grab her face with your feet and slam her down with you. 

You got up and blew the dust away. Cross came in and tried to attack from above but you blocked it and kicked her in the face sending her into a pillar "I know that way you attack...This...Killer tactic..." She rushed at you and swung her knife around but you blocked them all and summoned an orb with the souls surrounding it "...Chara...You in there?" You shot her back as she rolled on the floor. You stabbed her into the ground with the cyan knives "Your soul isn't the only soul in there...You've got someone else in there" Cross grumbled "Damn...How did you know?" "In my world...I fought a Chara who used insane yet smart tactics to attack...With her now fused with a Sans...This could be dangerous...I had better kill you" You raised your sword "Sorry..." She closed her eyes as you tried to lower your knife but you were wrapped in blue wires "Ink...?" "Help...Me" You heard ink wheeze. You were suddenly thrown out the window of the Judgement hall and down into the city where you crashed through a building and it landed on top of you.

As you slowly got up with the rubble brushing off you "Urgh...Ow..." You heard screams from the judgement hall! You slowly got up "Gotta...Save...Ink" A knife stabbed through your back "GAAHH! Grrhh" Cross chuckled "Now you're gonna answer my questions...Do you know how rare your timeline is?" You coughed up a bit of blood "Right! Really damn rare! Since your timeline is the only one where YOU specifically exist...The only boy. In the entire Underfemale timeline..." You grumbled and closed your eyes "G-gaster...I need...Help!" 

You looked around the black void "GASTER! Please!... I need you to save the timelines..." You heard a chuckle from behind "Oh fuck sake..." Chara walked infront of you "Look at you...All messed up and broken. I could just leave you y' know. But I plan to take your body and CONTROL THE TIMELINE!" You bitch slapped chara "Snap out of it! If I die here! The timeline you're from could die! And you with it! It doesn't matter how far away from our timeline you are they will find and kill you" Chara sighed "God I hate you...But Ok...I'll help. I'll be your new helper in bad situations since you were nice enough to lose your other one"

You stabbed Cross in the chest and slowly rose up "Heheh...I know how special I am...Since I'm special enough to kill you" You pulled out Cross' knife and stabbed it through her while taking your own knife out her chest "You stay there. I've got one more to kill" Cross fell to the floor "W-wait. Gah! Please!" You flew off. 

"Now Ink...Time to do what I should have done years ago!" You slapped Error into the wall as she dropped Ink "Ink get out of here. I can handle her" "B-but cross-" "Is down...Leave now...That's not a request" Ink slowly got up and left.

You glared at Error with your eyes slowly fading into a dark red "I'm going to kill you" Error chuckled "I'd like to see you try" You rushed behind her and sliced up her back she managed to glitch and you missed all your slashes. She appeared again but you slapped her into a pillar and you pinned her there with your knife "Well...I'm trying" Error growled "YOU FUCKER!" She turned and wrapped you in wires that you easily broke out of and you stabbed her in the chest "Now...Perish" Error grumbled, "I can't afford to die yet..." She glitched and disappeared...You slowly turned back to your base form "Darn...Lost her..." You flew down to Cross but she was gone too "...Snap..." 

You returned home after that and met with Sans as soon as possible "Sans..." "Heya kid-Woah! You look...messed" "Messed up. I know. Come on we're going to Grillby's" You stopped at Grillby's bar and you and Sans sat at the counter "So...Other AU's?" You nodded and took a bite from your burger as your wounds began to heal "That's impressive...So we gotta keep a lookout for this Error me and this Cross me right?" You fell asleep on the counter before you could answer "Hehe...Hey Grillby mind taking care of him while I head home?" Grillby nodded. Her fire grew a light pink as she was excited for you to be sleeping at her bar...with just you 2...alone.
