In my story Mr Incredible hypnotized the underminer with the hypno goggles Evelyn used to hypnotize him in The Incredibles 2 to send him to different superhero universes as a prank and killed people there but the underminer got killed
Elastigirl and Mr Incredible (without their superhero suits) are in their house watching the news on TV in their bedroom
News reporter (on TV): good evening. The attempts to find out who sent a villain known as the underminer to different superhero universes like Marvel, DC and other universes more have been fruitless…
Mr Incredible: Hahaha
News reporter (on TV): …until some moments ago!
Mr Incredible: ah!
News reporter (on TV): a shocking and traumatizing discovering has been made in new York city in the Marvel universe in the dead body of the underminer
Iron Man appears on TV with hypno goggles he found in the dead body of the underminer
Mr Incredible: i bet Evelyn deavor did that
Iron Man on TV finds a paper note in the hypno goggles, shows it to the camera and the paper says "greetings from Bob Parr, also known as Mr Incredible, from the Pixar superhero universe"
Mr Incredible: ah!
Elastigirl: Bob! It was you! You single-handedly killed people around different superhero universes!
Mr Incredible: i know. It's weird
News reporter (on TV): just a reminder. The station doesn't endorse vigilante justice. Unless it gets results. Which it will!
A picture of Mr Incredible without his superhero suit appears on TV with the phrase "get him" buzzing under it
Elastigirl: You didn't listen to me after i warned you!
Mr Incredible: don't worry nobody watches this stupid show. [He sees an orange light in the window] what's that ominous glow in the distance
An angry mob with torches with characters from Marvel, DC and other superhero universes walks to the Incredibles house to kill Mr Incredible
Mob: kill! Kill! Kill! Kill! Kill! Kill! Kill! Kill! Kill! Kill! Kill!
Mr Incredible sees the mob and realizes they're walking in the wrong way
Mr Incredible: Helen look! Those idiots don't even know where we live!
The mob stops walking, turns around and continues walking
Mob: kill! Kill! Kill! Kill!
Mr Incredible: damn it!
Mob: we want Bob! We want Bob!
Violet and Dash enter into the bedroom
Violet: monster! [She punches Mr Incredible's belly repeatedly] You monster!
Mr Incredible: did you watch the news?
Elastigirl: Violet calm down we have bigger problems
Violet: but I'm very angry!
Elastigirl: you're a woman you can hold into it forever
Violet: ok
Elastigirl: Bob you have to go out there, face that mob and apologize for what you did
Mr Incredible: i would but I'm afraid if i open the door they'll take all of you!
Iron Man: no we won't! We just want Bob Parr!
Mr Incredible: well maybe not you but they'll kill Frozone!
Frozone: I'm part of the mob!
The 5 original Guardians of the Galaxy of the MCU breaks into the Incredibles house
Star-Lord: here's the plan: we'll go upstairs, find Bob Parr and when we find him we kill him
Drax: i agree quill! Mr Incredible will die for what he did!
Rocket sees Jack-Jack
Rocket: oh here's a cute baby
Jack-Jack turns into a monster
Rocket: ahhhhhhh!!!!!
Rocket climbs into Star-Lord's shoulder and Dash uses his powers to bring Jack-Jack to Elastigirl and Mr Incredible's bedroom
Drax: where's the baby?! Maybe he became invisible
Star-Lord: yeah probably
Violet sees the mob through the window and sees Tony showing flowers to her
Iron Man: Let me get that on for you
Iron Man lights fire on Tony's flowers
Violet: well Tony lighted fire on Tony's flowers
Mr Incredible nails wood planks on the bedroom's door so the mob can't enter and the mob makes holes with their hands
Mr Incredible: stay back! I got my super baby son Jack-Jack! [He imitates laser sounds, the mob puts their hands away and a short time later they see him through the holes they made] Uh-oh!
The mob tries to attack Mr Incredible and Winston from The Incredibles 2 puts a wood plank on his window and Mr Incredible's
Winston: Dash! Climb across! Hurry!
Dash: but if they see you trying to help us they'll kill you!
Winston: they'll actually kill me only if i help your father. Now hustle your bustles!
The Incredibles start to walk in the wood plank and archers from different superhero universes point their bows to try to shoot Mr Incredible and trying not to shoot the rest of the family
Hawkeye: archers!
Oliver from Arrow: I'm using a green arrow so i know who i kill!
Jack-Jack uses his eye lasers to destroy the wood plank, the Incredibles fall, they survive the fall and Mr Incredible finds a little piece of chocolate cake
Mr Incredible: oh my luck is beginning to change!
The mob starts to pursue the Incredibles (while Mr Incredible eats the piece of cake he found) and the Incredibles get into the incredibile
Mr Incredible: let's get the hell out of here now! [He starts the engines] we lost them! Woohoo!
The mob carries the incredibile to the backyard of the house where the 6 original Avengers of the MCU prepare to crucify Mr Incredible, the mob takes Mr Incredible out of the incredibile, Elastigirl, Violet, Dash and Jack-Jack climb into a treehouse and Mr Incredible accidentally destroys the cross the mob was going to use to crucify him
Mr Incredible: You know the word apology is tossed around a lot these days [he points at his heart] but when it comes from in here…
MCU version of Spider-Man: shut up!
Spider-Man shoots a spider web at Mr Incredible's mouth and Hulk smashes Mr Incredible in the same way he smashed Loki in The Avengers 1 and Thor in Thor 3
Thor and Loki: yes! That's what it feels like!
Loki looks at Thor
Thor: now i know how you felt when Hulk did that to you
Violet: mom what are we gonna do?!
A blue portal appears and Cisco from Flash appears
Barry from Flash: vibe don't dare to help Mr Incredible escape!
Cisco: I'm sorry Flash! [He makes a portal in the floor] come on Incredibles! Jump!
Cisco jumps into the portal
Elastigirl: follow me kids!
Elastigirl, Violet, Dash and Jack-Jack jump into the portal
Mr Incredible: so long losers! [He jumps into the portal, shows his middle fingers in both of his hands and realizes he didn't escape] Uh-oh!
Mr Incredible starts to go down with his hands
Agent Coulson from the MCU: The top of his head is still showing! Claw at it!
The mob claws Mr Incredible's head and the Christopher Nolan version of Batman stucks a batarang on Mr Incredible's head
Batman: Hahaha! I'll know how he got these scars!
Hawkeye and Oliver, Thea and Roy from Arrow shoot arrows at Mr Incredible's head
Hawkeye: Haha! We hit him!
Mr Incredible disappears in the portal, Joe from Flash, Captain Lance from Arrow, some agents of shield, and police officers from different universes shoot at the portal with their guns, the portal becomes bigger and the Incredibles house gets destroyed
Iron Man: well they're now the Arrowverse's problem
The mob sadly starts to leave
