Chapter 1: Double Birthday, Or Should I Say Triple.
Tessa sat in her house, reading an article about the cloning machine that had given her her powers.
"Cloning Machine being redesigned for new purpose by National Supers Agency." she read on the headline.
"Well, I don't know what greater use they could have for it than what it did to me." Tessa said before Jojo and JJ came running in, now 7.
"Mom! Let's play!" Jojo said.
"Yeah, come on, Mom!" JJ said.
Tessa smiled at her kids before she folded the paper and put it aside.
"All right, kids. Let's go outside." she said before she and her kids ran outside and started to play a game of tag. Once JJ was declared the winner, they decided to play on the kids' swing set.
"Hey, kids, are you excited for your birthday tomorrow?" Tessa asked.
"YEAH!" the twins responded.
Later, after a game of Candy Land, LIFE, and Pretend Kingdom Hearts, the kids challenged Tessa to a burping contest.
"Are you kids challenging me?" Tessa asked, acting high and mighty.
The twins started off by burping together and then burping like they were making musical tunes, while Tessa fought back with loud or long burps. Eventually though, Tessa decided to use an old trick she used in burping contests with Elastigirl.
"Let's hear you beat this one!" Tessa said before drinking more soda and making a second head behind her own, making a burp that sounded like she was doing two at once before she got rid of the head so her kids couldn't see it.
"Looks like I win." Tessa said.
"So, Mom, what's at our birthday party?" JJ asked.
"Well, for starters, it's going to be at Chuck 's. Second, you'll have all the pizza and fries you can eat. Third, everyone's going to be there. As for everything else, you'll have to wait and see." Tessa said.
The twins then went and hugged her, "We love you so much, Mom." they said.
"Aw, thanks, kids, but I love you more." Tessa said with a smile as she hugged them back.
Later, she was having a drink of orange juice when she heard the doorbell and saw a young boy with blonde hair and glasses when she answered the door.
"Aunt Tessa!" he said before he hugged her.
"Hi, Adam!" Tessa said as she returned his hug.
"What's happening?" Adam asked as he came in and she gave him a drink of chocolate milk.
"Nothing much. I'm just helping my kids get excited for their birthday party tomorrow." Tessa said before she noticed Adam looked a little down.
"What's wrong, little guy?" Tessa asked, using her nickname for him.
"Just, their birthday's tomorrow, and mine's still a month off." Adam said.
Tessa looked sorry for him before she got an idea, "I'll tell you what, Adam. I'll go talk to your mom and see if we can celebrate your birthday tomorrow along with my kids!" she said.
Adam's face brightened before he hugged her again, "You're the best, Aunt Tessa." he said.
Later, Tessa walked up to Tina's door and knocked.
"Come in." she heard. She opened the door, only to see that there was no one in the living room.
"Tina? Where are you?" Tessa asked.
"In here." Tina replied. Tessa walked down the hallway and saw Tina in a room lifting weights. She had clearly been at this for a while, as she had more muscles in her arms.
"Woah, Tina, what's with the workout?" Tessa asked.
"Been working on these to enter a women's bodybuilding and strength contest." Tina said before she put down the weights she was lifting and grabbed a drink.
"It can't just be that. Does this have to do with our rivalry?" Tessa asked with a smirk.
"Don't miss a beat, do you, sis? All right, you got me. I admit, I'm jealous of Adam's love for Miss Multiple and I hope to impress him with my muscles. I've even been hiding them with long sleeves to keep them a surprise. Once he sees these, he's sure to be my biggest fan." Tina said before she flexed.
"Well, I came over to ask you something. You see, Adam's a bit down that his birthday is far off and I was wondering if you would be okay with me celebrating his along with my kids tomorrow." Tessa said.
Tina looked thoughtful, but unsure, "I don't know, Tessa. Hey, what say we arm wrestle for it?" she asked.
"All right, you're on!" Tessa said before they sat at a table. Tessa decided not to use her powers for this one. The two girls then started. Tessa struggled to bring Tina down, but found it very difficult. Tina started to gain the upper hand before she finally slammed Tessa's hand down.
"Oh, yeah! I knew all that weight lifting would pay off! I'm the best! Tina is number one!" Tina started to brag. Never a big fan of her bragging, Tessa got angry before she got an idea.
"All right, sis, you wanna brag? I'll show you somewhere you can brag!" Tessa said before she brought her back to her house, where Adam was playing with JJ and Jojo in the backyard.
"Hey, kids, wanna watch us arm wrestle?" Tessa asked.
"Yeah!" the three kids said before they sat on a nearby bench.
"Best two out of three, Tina." Tessa said before she used her powers to make her arms stronger.
"All right, Tessa." Tina said before they started another arm wrestle, which Tina and Tessa were about equal in strength, but eventually, Tessa slammed her arm down. The three kids clapped.
"Lucky, sis." Tina said before they went again, only for her to get beaten again. The third time, she struggled as hard as possible, but still ended up getting beat.
"All right!" Tessa said.
"You got lucky, sis. If these were a little bigger, you'd be in the loser's spot right now." Tina said as she showed her muscles.
"Wow! Cool! When did Mom get so strong?!" Adam asked, earning a smile from Tina.
"That's nothing. Check this out." Tessa said before she made her muscles bigger and flexed herself.
"Woah, Mom's so cool!" her twins said.
"Aunt Tessa, you ARE really cool!" Adam said before he ran and gave her a hug that she returned before picking him up.
Tina watched with jealousy before she thought, 'Enough is enough! I'll take this no more! If my sister wants to steal my son's admiration by beating me right in front of him, she better get ready for an unfriendly war!'
The next day, the party was going well. The kids had already had Happy Birthday sung and were ready to open their presents, when their moms started arguing about who got the better presents.
"I'm telling you, Tessa! I got the best for my son, niece, and nephew!" Tina yelled.
"Hey, you don't need to yell! This isn't a debate!" Tessa shouted. This argument went on for a few minutes before the two sisters started to compete against each other worse than ever, which made the party rather tense as their competitions raged on.
"Man, even Dash and Violet never made their parties this tense before their Bonding Days." Helen Parr said as she watched the two sisters grapple in a strength contest.
"You said it." said Bob Parr.
Finally, when things started to calm down, Tina had one last contest, a hot pepper contest!
"All right, whoever eats the most peppers out of this jar wins." Tina said.
"Very well." Tessa said before she ate a pepper, with Tina following. The amount of peppers they ate at a time increased to about four before Tina grabbed the jar and downed the whole thing! This drew awe from everyone as she smirked before she started sweating and her face turned red. At one point, steam even came out of her ears and nose and she screamed as she ran around.
"WATER! WATER! WATER! WATER! WATER!" Tina shouted before she grabbed a cooler and drank every last drop of water in it.
Tessa chuckled before the news report came on, "We interrupt this program with a breaking report! A heist at NSA HQ is risking the theft of a cloning machine currently being rebuilt for new purpose!"
Tessa gasped. If criminals got a hold of that machine, who knows what kind of forces they could unleash?! She slipped away while she thought no one was paying attention and changed into her suit. However, Tina had spotted her.
A few minutes later, the crooks were just fixing to drive away when they were knocked over by a multitude of Miss Multiples, which banged the machine around in the back before they tried to grab it and run, only for the many Miss Multiples to trip them, causing them to drop the machine and damaging it some.
"Sorry, bad guys, that machine isn't a toy." Miss Multiple said as she lost the clones before Tina suddenly showed up and punched one of the thugs.
"What the?!" Tessa asked before she watched Tina pick the two thugs up and throw them off the truck before she jumped down, only to have her arm snatched by Miss Multiple.
"Tina, what the heck are you doing?!" Miss Multiple asked.
"Trying to impress my son, whose admiration you stole from me!" Tina said as she shoved Miss Multiple back.
"You know crime fighting isn't a game! You better go back home right now!" Miss Multiple said.
"Why should I?!" Tina shouted.
The criminals looked at them arguing before deciding to make a run for it, also noticing the cloning machine start to spark.
"Are you challenging me?!" Miss Multiple shouted.
"Maybe I am!" Tina yelled before the machine started to glow, which they both took notice of before it blew.
