After the heroes defeated the Koopalings and sended them sky high, they all enter a door and see theyare in a large platform with lava surrounding it. Then a pod with Fawful's face flew down and Fawful emerges from it. "Ah, the fink-rats have arrived, along with their new frie-" He spots Megumi in surprise. "Impossible! I have the blasted you in the gut! Why are you the living!?"
"Well 1 word: 1-Up Mushroom!" Mario grinned.
Fawful growls. "I HAVE THE GROWLING! I will still pound you all like tuna!" He spins into a stylish outfit and brings out a remote and pressed the button as he entered the pod. They all hear a rumbling and see a large red Fawful-like mech with hammers for arms dropped down, causing the heroes to stare in shock as the pod rockets over it. (AN: His mech is based on the Mechawful I found in Deviantart by Marioshi64 and I give credit to him.)
"I HAVE CHORTLES! Do you like it? I call it the Super Mechawful EX! Now all of you fink-rats have the DOOM!" The mech opens it's mouth, then the pod enters it as he began operating the controls and the mech lifts it's hammer arms and smashes the ground, causing a huge shockwave the blows them away as Shine Knight stands on his ground.
"Fawful...you will pay for what you did to Megumi. And Cackletta will pay too. Now..." He looks at the group recovering and the Bros, Megumi, Izuku, Ochako and the Skylanders all stand by his side as he looks at the rest. "You guys stay there and watch, this will get ugly."
"But I want to fight too!" Teru complained as Aoi puts her hand on his shoulder.
"No Teru, let them do this. We don't want you to get hurt badly."
"But-"
"No buts!"
"Fine." Teru pouted.
"Now." Shine Knight and his friends all glared at the mech suit.
"Let's-a Go!"
"Okie Dokie!"
(Cue Fawful and Cackletta)
"I HAVE FURRRRRRRYYYYYY!!!!" The mech roared and prepares to slam its hammers at them but they all jumped away.
"One For All: Full Cowl!" Izuku chanted as his body gets surrounded by red veins and rushes towards the mech and prepares to punch it. "Delaware Smash!" He punches its arm away. Ochako uses her quirk and levitated rubble as the Bros hammered them to the mech, but it's not having any effect. The mech then begins to fire energy bolts from its antenna and they all dodged. Spyro flies around the mech and breathes fireballs, but the mech fires Bullet Bills out of its chest and he dodges some of them but gets hit. Pop Fizz in his beast form climbs up the mech and claws its head multiple times and Stealth Elf uses her acrobatics to dodge its bullets and lures them to hitting it in the back but he shakes them off and gets Eruptor in it's face and he barfs lava on it.
"ARGH! THE BURNING!" Fawful shouted within the mech as the lava monster jumps off and Jet-Vac shoots at its weaken face, but the mech manages to shake off the lava and zaps the Sky Baron out of the air.
"Eat this!" Shine Knight shouted as he punches the mech multiple times then kicks the leg, causing it to stumble but still standing. He lifts his right hammer arm and smashes the place Shine Knight was on but when he removed it, he was gone. But Shine Knight zips behind him and axe kicks the head as it turns it like an owl and fires a purple laser out of it eyes, as Shine Knight takes damage. Mario and Luigi both jumped on it's parts to get higher and when they reached the head, they took out their hammers and swung them down, but it caused a gong sound as the mech fired more energy bolts at the Bros and they crashed down and the mech began to laugh.
"I HAVE CHORTLES! This precious mech was build by the remains of Bullies and Metal Blocks! You can't leave a single dent on it!" He laughed as the mech lifted both of its hammers and prepares to finish off the Bros. "I HAVE CHORTLES! Now Mario Bros, prepare to be the squashed!" As he was about to crush them, he felt a fireball hitting him and sees Megumi who was the one who threw it. "Oh, so you want another death wish?"
"Well, I still want to kick your butt when you shot me, and hurted so much! But if you try to kill my new friends that we met in this world, I will take you down!"
"I HAVE CHORTLES! Do you think you and your friends can defeat me?" He mocked as Izuku attempt to attack him but he hammers him to the ground as Ochako looks in shock and uses her quirk to levitate more rubble but the giant Mechawful breathes purple gas from its mouth and as she feels weaker and gets hammered towards Izuku's side. The Skylanders all charged but they get caught up in the gas and he hammers them towards the two. Shine Knight flies towards it avoiding the gas and gives it a strong punch as he falls over and the knight stands over him and lifts his sword over its head.
(End Music)
"Any last words before you're defeated?" He asked as Fawful laughed.
"Oh yes...HA!" He immediately emerges from the mech's mouth and fires Shine Knight's bracelet off and he looks in shock. Then his sword vanishes and turns back to Seiji Sagara, then Fawful grins and punches him in the gut then shooting him off as he falls to the ground.
"I HAVE CHORTLES! I have seen the transforming through that red jacket's fight with Cackletta. I knew it was the source of power of that Glowy Green had! So what are your last words, Shiny Knight?" He asked as Seiji tried to get up but gets zapped by the mech's lasers and the Mario Bros, Izuku, Ochako and the Skylanders also gotten zapped as they fell unconsciously, leaving Megumi, The Eds, The Sakurada Siblings, The Witchlings, and Minky Momo left.
"W-We need to help them!" Akane exclaimed she ran.
"Akane, no-AAAAAAAHHHHHHH!" Shuu shouted as he and the rest all gotten shocked from the mech's beams and they collapsed. Megumi is now left.
"I HAVE CHORTLES! You are now alone, Pink Ponytail! Where is your hope now!? You are nothing but a worthless teenage girl with a mind of a child!" He taunted as Megumi grits her teeth as she kept on blasting fireballs not giving any effect on it as it swung its hammer arm down as Megumi's hands burst into flames and rockets out of the way and fires her laser eyes, but they were just bouncing off of it and fires another beam as she kept on dodging and dodging until one manage to hit her as she falls down to the floor as the mech marched over her.
"Now...LET'S GIVE YOU A FINISHING!" He shouted as the mech raised both of its hammer arms and swung them down as a barely conscious Seiji stares in horror.
"No...Megumi...!"
"BE. THE. CRUSHING!!!!" The hammers reached down to her, creating a humongous crater in the process.
"NNNNNNNOOOOOOOO!" Seiji screams in agony, seeing his childhood friend being crushed...
"NO...I...WOOOOOOOOOOONNNNN'T!!" A voice shouted and exploded a wave of pink energy, catching the mech off guard.
(Cue X-Treme Fight from Digimon Adventure 2020)
We see Megumi with a new appearance. It was an updated version of Cure Lovely with light pink pauldrons, magenta gauntlets, white boots, a rose combat skirt with pink shorts underneath, pink breast plate with her pendant attached to it, and her hair down and long and was now brighter pink with heart shaped earrings, and her eyes were now bright pink.
The mech stared in shock but didn't care, he tried to smash her with its hammers again but Megumi disappears and reappears behind and gives it a strong kick, making it fly across the ground, but lands on it's feet. Megumi appears in front and gives it a strong left hook, and right hook, then left again, as she gives it a machine gun punch attack while she shouts and punches the mech strong enough to send it rolling across the ground as she pulls her fist back as it glows pink and punches it again, as it went through its chest.
"ARGH! The glowingness! She is destroying my beautiful mech! No more Mr. Nice Bean!" Fawful yelled as the back of the mech's hammers emerges rockets and they fired, making the mech spin rapidly fast and firing alot of energy bolts at her. Megumi flies through the bullet hell, dodging, kicking, and punching the bullets away as she shouts and dropkicks the mech in the face, making some of its parts fall off. It attempted to swing its arms again but they were jammed and Fawful checks and sees Sparx was the one that was messing up in the inside. The dragonfly manage to sneak inside one of its openings thanks to Eruptor's lava vomit and he emerges out of the mech, giving it a smug.
"I HAVE ANGER! That bug messed up inside of my machine! He will pay!" Fawful tried to fire another laser at Sparx but Megumi summons her sword to cut off the antennae and she slices the head off revealing Fawful.
"Uuuuuuhhhh...mercy?"
"...Nope." Megumi blunted said as she flew up in the air and raised her sword high as she flies down like a meteor and swung it hard enough to slice the mech clean in half as it causes a huge explosion.
(End Music)
Megumi flies down and looks at the explosion...then Fawful comes crashing down and is now all bruised up with burn marks.
"I...have...arh...fury..." He groaned as he lies down unconsciously. Megumi looks at her injured friends and approaches them, then she holds her hands foward as they glowed. All their injuries started fading then they woke up.
"Ugh...What happened?" Eddy groaned.
"We've been zapped by that green freak, that's what happened." Spyro said.
"Megumi?" Seiji said as he stared at her new appearance. "You...transformed."
Megumi giggled. "Guess Mao's gifts are pretty powerful, don'tcha think?"
"Yeah."
"Wow, Megumi!" Ochako runs towards her. "You look so fantastic!"
"Thanks Ochako!" She turns back to normal.
"I hope that form will give us chance against Bowletta!" Mario said as Fawful tried to attack but...
"Oh no you won't fiend!" Prince Peasley flew on the scene and strikes Fawful down with his rapier. He tried to fire a beam but Mario whacks him on the head with his hammer, then Luigi hammers him out of the castle.
"Home Run!"
"I WILL BE BACK YOU FINK-RAAAAAAAAAATS!" He screamed as he turned into a twinkle.
"It seems that we have got rid of that loud mouthed fiend! Now onward!" Peasley said as he flew ahead, then a bridge emerges revealing the way to the throne room.
"Well everyone, this is it." Mario said as they all prepare for the final battle. "Ready?"
"Right!"
"Then, Let's-a go!" They all ran towards to the throne room before Seiji picked up his jewel and ran ahead.
The final battle awaits...
