Final Part: The History of The Super Hero Bros Begins.

From the Previous Part: The Heroes have Broke Medusa's Staff, and Everyone went back to Normal. Except turn into a Giant Monster and wreck havoc. But the Heroes has found the Cosmic Orb and used the Orb's power to turn into Super Forms, and now they charge at Medusa and their Troops.
The Final Fight Begins!

Star Cape Mario spins around super fast and uses his Cape, and sends over hundreds of troops flying.

Grand Hammer Kirby slams his huge Mallet on the ground, and the waves have made the enemies jump upwards in the air. Super Sonic use his Speed to beat them in a Flash.

Pikachu let out a huge discharge around, shocking everyone.

Fierce Deity Link used his sword beams to blast the big Titans and then slash them into small pieces in one slice. Link walks away from the explosion in slow motion.

Blu the Mecha Kraken set off and threw dozens of Splatbombs and Splat Missiles and knocked back some Troops with his Metal Tentacles.

Puni God Awoken Nate and Rampaging Whisper are attacking from above with their moves. Nate attacks with his Floating Orbs and Whisper breathes out  Huge Stinky Green Breath; that Disintegrate them into Ashes.

The group kept attacking the troops until there was no more. Medusa is furious to see she's failing like this, but she's not giving up that easily; she unleashed another laser, but Metroid Suit Samus steps in and uses her own laser to counter Medusa's laser and their lasers hitted each other. Samus used all her power to make her laser bigger, and it hitted Medusa in the eye.

Now, all the Heroes land their hits on Medusa. Pikachu hits her with Volt tackle, followed by Kirby and his Grand Hammer. Mecha Kraken Blu splats her with so many Tenta missiles, covering her in Blue Ink and making her blind. Star Cape Mario grabs Medusa's snake hairs and slams her on the ground, followed by Super Sonic's upper punch. Fierce Deity Link hits Medusa with more Sword Beams. Medusa tried her best to retaliate with an attack but got hit in the head by an Orb from Puni God Awoken Nate. Then Star Cape Mario grabbed Medusa's right leg, spins around, and toss her high in the sky, all the way to space. As Medusa was floating in space, Puni God Awoken Nate and Rampaging Whisper did a huge Punch on Medusa, and that sent her falling fast back at Earth and crashed into her own Statue. Everyone flew into space, and they all dived down while spinning and collided with each to make a huge rainbow punch. Medusa got back up, and she unleashed a huge fire breath, but the Big Punch had landed on her, creating a huge explosion that rainbow waves all around the planet. Palutena protected everyone from the Waves with her huge force field.

After the dust clears, the Medusa Statue is destroyed, Medusa goes back to her normal size, and her head is cut off from her body (that was from Link's sword), the Gang are still in their Super Forms. They all look at Medusa to see if she's moving or not. Medusa is still alive, but she can barely move an inch because of the pain she took. The crew was about to do more attacks, but Palutena stopped them.

Palutena: "That's enough!"

Palutena walks to Medusa while the crew makes way and space for her.

Medusa: "...SSSSoooo... You're going to finish me off for Real?"

Palutena: "Listen... Despite everything you've done... I can't."

Rampaging Whisper: "Huh?!"

Palutena: "You're still my sister; This whole situation was honestly my fault as I should've been a better sister to you a long time ago."
