After retrieving the second chaos emerald, Shadow and Pinkie began walking back to their home to rest up and think of a new plan. "Daddy, are we still collecting the chaos emeralds?"

Shadow looked to the mystic gems in his hands. "Whatever that alien leader is up to he requires the emeralds powers, the less he has, the more of a chance we have of stopping him." As they began walking along a damaged highway a small alien aircraft flew above them. "What the hell?" Shadow squinted his eyes and noticed a thin energy field around it.

"Should we go after that?" Pinkie looked around until she caught a glimpse of something that made her grin. "Hey Daddy, look!" She pointed her tiny hoof in the direction of a black and red motorcycle. Turning back to her father they both smirked.

"I'll drive, you shoot." Pinkie nodded and hopped onto the back of the bike as Shadow started the engine. "Huh, someone actually left the keys in this thing."

"But wait, won't this make us go slower?" Pinkie asked as the pulled out a modified version of the party cannon that was slimmer and had the look of an advanced rocket launcher.

"Yeah but it'll make us look more badass." He pulled out a pair of sunglasses and sped down the damaged road. Along the way they came across a group of black aliens attacking a squad of soldiers. Shadow jumped off the bike and quickly dealt with the attackers. Picking up a gun from a nearby gun crate he hopped back onto the bike and they eventually caught up to the alien ship. "Ok Pinkie, let's do this!" The pink filly smirked and aimed her 'party bazooka' and fired. The projectile launched from it was surrounded by confetti until it his a blue shield, the energy field then spat off small parts of itself like shattered glass when it was hit.

Shadow levelled his new assault rifle and began unloading the entire clip onto the shield, chipping away at its durability. When he ran out of ammo he discarded the weapon and pulled out his sidearm. They both gave the shield everything they had until they ran out of ammunition. "Daddy, I have a plan!"

"Yeah, what is it?!" He slammed his foot into the ground as they slid around a sharp corner.

"Use chaos control to send me ahead so I can ready the party bombs!" Smiling, Shadow took out a chaos emerald and charged its energy.

"Chaos Control!" With a flash of light Pinkie was gone. After picking up another pistol he returned to shooting the aircraft. He came to a point where he had to leave the bike behind and pursue the ship on foot. Activating two large doors he passed into the next area. Looking ahead he saw a few baby blue spheres along the route the ship was taking. As it flew over the blue items the balls exploded into large clouds of fire, candy and of course confetti, heavily damaging the shied until it turned green.

Pinkie sat on top of a phone both with her party cannon ready. "Party hard." She fired one last shot at the ships shield and it shattered like glass, leaving the aircraft vulnerable.

A group of soldiers noticed this and began firing at it, many of their robots doing the same. Soon the ship hit the ground and slid across the road. Shadow pulled out a black smartphone with his emblem on the back and sent a message to someone. "Come on Pinke, I'll buy you some ice cream on the way home." She jumped with joy and began skipping beside her father as they left the area.

"What did you do about the pilot daddy?" Shadow just laughed.

"I let someone do something that they haven't done since the first week you were brought to us."

...

Meanwhile, the alien pilot shakily climbed out of the wreckage and breathed heavily. Opening his eyes he was greeted by two black metal feet. Looking up he saw Omega standing over him with glowing red eyes. Omega then slowly pulled a stick into the aliens vision.

...

"You're cruel daddy."

"They started it."

Pinkie sat on top of Shadows head as she happily licked her ice cream while humming to herself. Just then the weird star creature floated by them. "He Pinkie, did you see that?"

Pinkie just looked at the creature and groaned. "Didn't I kill that thing already, he's just so mean it makes me wanna cus!"

Shadow immediately stopped. "Who taught you how to swear?"

"I heard mommy yelling a lot of swears when she stubbed her toe on the coffee table." Shadow faceplamned and continued on. Turning the corner he spotted the creature with the third chaos emerald by its side. Pinkie noticed this and pointed her hoof at Dooms Eye. "Daddy..." Shadow took a fighting stance. "...get'em!" He shot foreward and readied his fist to punch the star in the eye. As he got close he was thrown off balance as a gust of wind blew across the area.

Looking up he saw a large puffy alien creature with large wings and one huge eye.

"Say hello to the Black Bull you traitorous hedgehog, he shall be the instrument of your destruction!"

"I can't exactly he a traitor to someone I never sided with in the first place now can I?" Dooms Eye just flew away and the Black Bull roared.

"Daddy, can I take this one?" Pinkie asked in an excited state.

"Go right ahead Pinkie, just don't hurt yourself." Pinkie jumped off his head and Shadow walked to the side of the street. "Pinkie..." Pinkie readied her replenished party bazooka. "...sick'em."

Running over to a building Pinkie began scaling the wall while shooting multiple party rockets at the large creature. It shot a ball of dark energy at her and hit her in the chest, causing her body to flash in and out of existence while a few rings spewed out of her body. "Hey! That was my allowance you jerk!"

The bull flew down the street and started shooting waves of electricity at her as she followed it. She scaled a wall again and hit its eye with a homing attack, causing it to scream in pain. She then unleaded a flurry of attacks onto the alien. Once it was weak enough it fell to the ground. Pinkie walked over to its mouth and placed a small blue orb between its teeth. Walking away the ball exploded, finishing the Black Bull. "Cool fillies don't look at explosions."

Shadow chuckled and grabbed the third chaos emerald. "C'mon, let's go home, hopefully without any interruptions this time." Pinke placed her hoof in Shadows hand as they walked out of the city together.

Author's Notes:

No, I'm not doing the hero story, I'm just gonna do a kinda zigzag pattern with the levels and alter the story a bit.

Tell me where you want the duo to go next.
