"BEHOLD! THE UNDERMINER!" The Underminer yelled as the Incredible family and Spider-Man finished putting their masks on and raced over to find a way to stop him. "I AM ALWAYS BENEATH YOU! BUT NOTHING IS BENEATH ME! I HEREBY DECLARE WAR ON PEACE AND HAPPINESS! SOON, ALL WILL TREMBLE BEFORE MEEEEE!"
"You three stay here." Bob tells the kids.
"Wait, should we even be doing this?" Helen suddenly asks. "It is still illegal."
"When has that ever stopped us?" Peter asked them.
They watch as the Underminer starts turning his giant drill and it begins to go underground.
"We're gonna lose him." Bob stated to Helen who was still carrying Jack-Jack.
"Oh, all right." Helen gives in and places Jack-Jack in the stroller. "You guys stay here and watch after Jack-Jack!" She instructed the kids.
"But I thought we were-" Violet was asking as their parents raced off.
"You heard your mother!" Bob said as he and Helen raced off before she stretched herself into a trampoline that Bob used to bounce into action on top of the drill.
"Okay, guys, make a perimeter." Peter told them, believing they could do more than watch the baby. "Clear out any civilians, no one innocent gets hurt. But she's right, someone watch Jack-Jack."
"Thanks, Peter. At least you take us seriously," Dash said as Peter leaped and swung off towards the destruction. "I call perimeter!" He then started to dash off whilst Violet tried to stop him using her forcefields.
"You're not going anywhere, you little maggoty creep!" Violet stated but failed to stop him as he raced off.
Peter swung over where the drill is, keeping up with Helen above ground and using his senses to keep track of it. Whist the ground began to shake, Peter swung down and stopped the debris from falling on several civilians trying to find their footing.
"We need to slow the drill down when it comes back up! Make sure it doesn't go any further!" Helen instructed as Peter landed on the building beside her.
"Minimize collateral damage. Got it," Peter understood as he swung ahead of her, keeping the buildings that were getting shaken up by the drill creating the ground to become unsteady.
Before he could do anything else, Peter's spider-sense started going off again. He saw some dust puff up from different banks and noticed cracks forming under them.
"Uh oh...He did it..." Peter's fears were realized.
The Underminer blew the road out from under the buildings to bring him down to his level. Peter quickly made web lines that stopped the foundation from falling any further and saving the people surrounding it.
Underground, the Underminer reached the vaults that fell below and used a giant vacuum to suck up all the loose cash.
Bob approached from behind, standing in a heroic position. "Underminer! We meet ag-" The Underminer then turned to face him, causing the vacuum to suck him in.
"Oh, great! Now, he's on the agenda." Underminer groaned in annoyance before continuing to suck up the money.
Bob tried to get back up when he was pushed back by more money filling the container he was in when he began to feel the drill was moving again.
He marched up to the door of the container and began punching it off and got free, only to be met with a smack down from Underminer.
"Incredible! Meet Jack Hammer!" Underminer says as his robot fists began to go up and down like a real jackhammer before he punched Bob as he tried to stand and put his fist below his chin and repeatedly jackhammered him.
Bob returned the punch and gone in to punch him again only to be met with Underminer to grab his fists, but Bob picked him up and tossed him at the controls, causing the drill to begin to rise back up to the surface.
"Buh-bye!" Underminer cried as Mr. Incredible turned to see him enter the vault with the money, only to reveal that it's another smaller drill and he uses it to escape.
Bob looks back and forth between the Underminer and the drills controls and knew he can't do both and raced to the controls.
He tried to stop it but ended up breaking the controls as the drill was seconds away and breached through the ground and tore through the streets.
Back at the track, Dash took notice of the cloud of smoke in the middle of the city and tried to keep the town back.
"Everybody, stay back!" Dash told them all, keeping them back. "Okay? Stay back!" He tells everyone before racing off to try and catch up with the others.
Violet watched her brother run towards the action and became a little mad at her job. "You're not sticking me with babysitting!" She promised and ran off to catch up with them as Jack-Jack giggled the whole time.
Peter and Helen swung their way over and landed on top of the drill.
"Gotta be honest, when I first put the suit on, I never imagined I'd be here." Peter told Helen.
"Yeah, we never do." Helen agreed just as Bob joined them after exiting the drill.
"I can't steer it or stop it. And the Underminer's escaped!" Bob informed them both.
"We'll have to stop it-" Helen was saying when Peter saw that the drill's about to hit the rails.
"Guys! The monorail!" Peter cried as the monorail came past and was hit off the track and began to fall just as Frozone came in and started to slowly get the train down safely.
"Frozone! Yeah!" Bob cheered on his friend as he was able to get the monorail somewhere safe before he could go back to help.
"We have to stop this thing before it gets to the overpass!" Helen told the two of them.
"I'll try to keep it away from the buildings." Bob said and dropped down before pushing the drill away from the buildings.
"I'll try and stop this thing." Peter offered as he leaped ahead of the drill and began shooting several web canisters to try and stop the drill from turning.
Dash was speeding up to them when he noticed a car was coming in and was about to hit an old lady crossing the street.
"Hey, lady!" Dash cried as he ran up to them and quickly got her out of the way just as the car crashed where she was recently standing.
"Thank you so much, young man." The lady thanks Dash as he fixed the glasses on her face.
Dash then started to hear the unmistakable sound of Jack-Jack squealing and turned to watch the stroller containing the baby to come out from behind some crushed cars and approach the two of them almost on its own before Jack-Jack began floating and landed in Dash's arms.
"What?" Dash asks when he suddenly understood what's going on. "Violet!" He cried just as he saw the form of his sister enter and exit a cloud of smoke as she became visible.
Bob tried to stop the drill from its sprockets only to end up getting pulled under.
Peter finally managed to stop the drill just as he looked to notice the drill was about to hit the bridge. Helen seemed to have also noticed this and leaped onto it and pulled the traffic to a haunt just as the drill came by and the bridge came apart.
Some people were too close and began to fall off the bridge, but Peter quickly ran over, rescued the woman from her car and quickly shot a web at the bridge before dropping to the ground and letting the woman go.
Rubble kept falling and Peter noticed some girls who were going to get crushed and was about to react when two forcefields came flying in and destroyed it.
"Good job, Violet!" Peter congratulated just as Dash came past and handed Jack-Jack to him.
"Heads up, Pete." Dash said before speeding off, leaving the hero with the baby.
"What- Dash!" Peter cried and looked to the baby who kept chuckling at him.
Violet ran past and was up against the drill when Helen noticed her. "Violet?! Who's watching Jack-Jack?"
"Dash's watching him!" Violet says when she looked to her dad and Peter swinging over and handing the baby to him.
"Sorry, Bob!" Peter apologizes as he swung ahead and quickly slingshot himself back at the drill and landed inside with Helen.
"What?! Peter!" Bob cried as he just dealt with it. "It's headed for city hall!"
"Mom needs help!" Dash stated as Bob helped his kids get up onto the ladder and start climbing.
What they missed was two tech genius's watching the action.
"They're out in public again!" The more well dressed, clean shaven man stated as he looked to his casually dressed, goateed face friend. "This is our chance!" He stated just as Frozone came gliding past them.
"Happy, quick. Follow them!" The goateed billionaire told his driver. "Follow Frozone!" The driver then took off and started chasing after the heroes.
The heroes all made it inside the drill where they noticed Spider-Man and Helen were already getting to work on destroying it.
"What are we trying to do?" Bob asked.
"Yank that tank out, it'll cause the engine to overheat and stall out," Helen instructed her husband.
Outside, Frozone kept shooting ice, trying his best to stop it from destroying city hall.
Peter was currently ripping at the tank of green coolant and slunk behind it, pressing his feet against it while bracing against the metal.
The tank was creaking and cracking, and then he gave a good push, and the tank came crashing to the ground.
Then Peter's spider-sense went blaring again, as the entire engine began heating up...and then this giant boiler looking thing started turning red with heat.
"Question...is that the engine?" Peter asked.
"Yeah, why?" Helen asked.
"You do realize this thing is going to explode right? And with the heat capacity of the boiler's two and a half inch thick steel, it'll build pressure akin to when the Omnidroid exploded! With us still inside!" Peter explained just as Violet, and Dash came running in.
"What are you kids doing?! Get out of here! This thing is going to explode!" Helen stated.
"There's no time!" Violet said as she went up to everyone before handing Jack-Jack to Helen and made a force field around all of them.
The boiler's temperature rose, pressured built and soon...boom! The boiler exploded and then the rest of the inside of the drill blew up along with it.
Violet luckily protected all of them from the blast, as they all laughed at the job.
"We did it!" Dash cheered only for the opening to open, and they all have shotguns and rifles being pointed at them by police officers.
"Freeze, Supers!"
"Oh, what did we do?" Bob wonders.
Frozone kept going as he reached an alley only to be met with the driver, Happy Hogan.
"Excuse me, Mr. Zone?" Happy asks as he got out of the car only to see Frozone left, and his feet were frozen in place.
"Sorry, but I'm not really supposed to be here." Frozone said and went to find a clearing.
"Which seems wrong...doesn't it?" Happy asks, causing Frozone to turn back to him in curiosity. "I'm here to talk to you about an initiative to bring the Supers back."
