(Warning, this is a cartoon physics, and object tf fetish story, if you don't like that, don't read this.)

In the back alley streets of the city a strange, flat, red and black blob slid beneath the concrete. It slid towards a very inconspicuous door. Slowly, the strange blob rose up, gaining a much more human and appealing shape. The shape of Elastigirl

“This better be it!” Elastigirl said as she stretched a bit. “All the clues seem to be pointing here.” She got a good look at the door and then tilted her head a bit. The door was made of rotten wood and looked like it was going to fall apart any second. “This doesn't seem like a super villain lair.” She then shook her head. “Of course it wouldn't look like a supervillain lair…” she thought to herself. “... This is probably a master criminal who knows how to hide.”

Elastigirl grabbed the knob of the door and twisted it. It was a miracle that the door didn't immediately fall apart there. Opening it, she got a good look at the super villain layer and it was…let's just say less impressive than she was imagining.

The place was run down, grimy and overall a disgusting living quarters. There was trash everywhere, the wall's paint was peeling off like crazy, it was hard to tell if the roof or the floor would be the first to collapse if hit by a light breeze.

Elastigirl was completely perplexed. “You gotta be kidding me…” She said as she looked around. “... This place is disgusting. What self respecting super villain would choose to live here?” No one seemed to be home at the moment. “Well, I guess I can start searching for that diamond uninterrupted at least.”

There weren't really that many places to search to be honest. Just some rotten cabinets and a few chairs. One of these chairs had an odd pillow on top of it. It was red, white, blue, and white flesh-toned. More vibrantly colored than anything else in the rundown lair. What caught the elastic heroine's eyes the most was the weird pattern on the pillow. It seemed to have a human face with crossed eyes and puckered lips.

Elastigirl couldn't help but be slightly creeped out by the pillow. “Like most supervillains, this one's a little bit messed up in the head.” She thought before turning away from the chair to continue her search.

Eventually, opening one of the cabin doors, she found what she was looking for. Resting on a pillow very similar to the seat cushion resting on the chair was a massive diamond. This one being black, white and flesh-toned.

“Ha!” Elastigirl yelled as she pulled out the pillow holding the diamond between its lips. “The villain's not here but at least I got the diamo…”

“What are you doing there!” Someone yelled out behind the heroine.

Like an instinct, the hero turned around with lightning speed and ready her open fist, turning it into a hammer. Elastigirl got a good look at the fiend.

The villain had a pink latex suit that covered her entire body except for her head and a convenient boob window.  The top of her head was covered by a pink bandana that went all the way down to her nose. The rest of her head was exposed, showing off her white skin and her long, red hair.

While her costume was pretty simple, Elastigirl still kept her guard up. “So, The Mastermind finally reveals herself. WHO ARE YOU?!

“Um…” The strange villain was still caught off guard a bit. “...My name is Momentum.”

“Never heard of you…” Elastigirl replied. “... You must be new.”

“Hey wait…” Momentum seemed offended. “I've been doing this for years. How could you not have heard about me?”

“You must be pretty good at keeping your head down.” Elastigirl replied, refusing to underestimate her.

“But I've been trying to make a name for myself.” Momentum groaned. “I'm not a nobody.” She seemed generally offended by the heroine's ignorance of her. “I steal a giant diamond I cannot sell, and I don't even get the fame for it.”

SLAM!

Momentum barely dodged Elastigirl’s fist as a slam down upon the floor. “Don't worry about fame.” The heroine said as she put down the pillow. “A lot of people are going to know who you are after reading the news of your arrest.”

“Oh shit.” Momentum gulped before turning and running out of her lair and into the alleyway. “That's not the fame I want!”

(Edited)

“Get back here!” The elastic heroine yelled as she pursued her prey. She quickly jumped in the air and started compressing her body. In an instant, she became a basketball shaped object. “Time to roll!” She thought as she did her best Sonic the hedgehog impression and started revving up for a spin dash.

Meanwhile, the dumb villain was too much in a panic to realize where she was running too. Instead of obviously running towards the open Street, she ran straight deeper into the alleyway until she reached a fence. A straight up dead end.

“Oh no…” Momentum mumbled as her face turned white. She turned back towards the ball that was still revving up, sweat coming down her face.

“I got you now!” the heroine yelled out right before launching like a cannonball towards the petty thief.

Momentum raised their hands towards the speedy object and prayed.

BZZZZZZZZZ

The ball stopped on a dime just inches from the criminal's face.

PLOP!

It fell to the pavement, bouncing around for a bit before coming to a complete stop.

The ball just laid motionless; not even a single twitch coming from it. The ball had a very simple design. The top of the ball was Brown, the bottom was black, and the majority of it was a solid red with The Incredibles logo in the center.

Momentum was still frozen in fear. After about a solid minute of just looking at the ball, Momentum bent down. She slowly reached for the ball and picked it up. She held it with both her hands.

SQUEAK!

She squeezed the ball, being as squishy Play-Doh. “It worked?” She asked herself as she continued to stare at the ball. “It worked!” She yelled out in triumph, holding the ball over her head.

She brought the ball close to her face again. “Well, it looks like I beat my first superhero.” She said smugly before giving the ball another squeeze.

SQUEAK!

An evil idea then came to the supervillain. “You know, I don't need a basketball right now.”

SQUEAK!

In that instant, she crushed the ball in her hands, compressing it with all her might. “I could go for something smaller, HAHAHAHA!”

She then began morphing her new plaything. Cruelty compressing it with satisfying glee. It only took about a minute for the dastardly criminal to get her object in the right shape. In her hand was now a cute little red baseball with a cute little Incredible logo.

“Yes, the perfect shape!” Momentum said mockingly as she squeezed the little ball in her hand. “To be perfectly honest, I didn't even know that would cancel out your elastic powers.” She slowly carried the stress ball back into her supervillain lair.

Once inside she walked up to one of her cabinets that a former heroine rudely opened without permission. “My powers are only temporary.” She said as she pulled out a can of rubber cement. “Let's fix that.”

(The next day)

The supervillain, now in her civilian clothes, walked into a random toy shop. Trying her best to act casually, She walked up to the $1 bin with a bunch of cheap toys in it. She reached into her cleavage and pulled out a red ball with The Incredibles logo plastered on it.

SQUEAK!

She gave the simple toy a good squeeze as she put on a smug smile. Without so much as a word, the super villain dropped the ball into the toy bin, not even giving the object a second thought.

The ball just laid there along with the other cheap toys. The ones proud heroine reduced to a simple plaything, only worth one measly dollar. Soon to make a little kid very happy.

(THE END!)
