Penn was now back in the rainbow void, with his friends by his side.

"WHAT?!" Bill Cipher was shocked, "YOU SAVED THEM?!"

"Yep!", Penn said, "And now I'm going to save you!"

"I don't need to be saved." Bill said.

"He's right, Penn." Sashi said, "This is starting to be just like UNDERTALE."

"How about a change of fandoms?" Penn asked.

"No, just battle like normal." Sashi said.

"Wait!" A puddle exclaimed. It reshaped itself into Shope.

"Shope?" Sashi asked, "What happened to you?"

"Penn awakened a new power in me!" Shope explained, "I can transform into different elements now!"

"Really?" The other Noobs asked.

"Oh yeah!" Shope exclaimed, "Flame On!"

"Marvel's definitely going to sue us for this..." Boone groaned, as Shope wreathed herself in flames.

"Aww." Shope moaned, as she extinguished herself.

"Enough talk, let's fight!" Bill exclaimed.

Shope covered herself in metallic armor to protect herself from attack.

"Nice!" Sashi said.

"I can still move with it too!" Shope exclaimed, her voice in a metallic pitch, "and watch this!"

Shope's arm transformed into a sword. She then slashed Bill.

"First attack!" She exclaimed, as she returned to normal.

"Don't hog all of the fun!" Sashi said, as sent out Yanmega and surfed on the Bug Type Pokemon.

Sashi kicked Bill.

"That's fun and all, but what about this!" Roach exclaimed, as he rocketed into Bill with a giant fist.

"Ow!" Bill yelled, "Not fair!"

"Time for a Continental Crush!" Shope exclaimed, "Fists of Rock, activate!"

Shope's hands became rocky. She used all of her might to create a massive boulder, about the size of a Wailord.

"FUS RO DA!" Shope yelled.

"Where did that come from?" Kevin asked.

"I've been playing Skyrim." Shope noted.

"Oh." Kevin said.

"Nope!" Bill said, as he teleported, "By the way, did you know I can use any Stand effects without the actual Stand?"

"Watch as I do Star Platinum!" Bill exclaimed.

"Watch out!" Tyler said, as he grabbed the Part Time Heroes and teleported them out of the way.

"ORAORORAORORAORAORAORAORA!" Bill yelled as he tried to pummel the heroes. But it failed.

"ZA WARDO!" Bill exclaimed, as he froze time.

"I've got you right where I want you!" Bill exclaimed.

"I can't move!" Penn cried.

"I've got Killer Queen too!" Bill exclaimed. "Killer Queen can erase you at any time. For you see, Killer Queen can turn anything it touches into a bomb."

"Now for it's third bomb: BITES ZA DUSTO!"

Bill looped time back to the beginning.

"ENOUGH!" One of the Pillar Men exclaimed.

"KARS?!" Bill was shocked.

"Bill Cipher, you think you can beat these heroes in a battle?" Kars asked.

"Oh yeah!" Bill said, as he fired a giant laser that disintegrated Kars.

"WHAT THE HECK JUST HAPPENED?" Penn asked.

"Was that a JoJo reference?" Boone asked.

"Your worlds are falling." Bill said, "And soon, there will be nothing left."

"I AM THE ULTIMATE LIFE FORM!" Bill bellowed, his voice as loud as Krakatoa.

"AH FRICK MY EARS!" Sashi yelled.

"I WON'T LET YOU WIN!" Penn yelled.

Penn didn't get hurt by Bill's battle cry.

"What's happening?" Bill was shocked.

Penn knew what was happening. The Dimension Warriors had gotten so far on their journey. It would be game over for the entire multiverse if they lost.

That's why Penn was the leader of the Dimension Warriors. Even through all the pain and suffering, Penn never gave up.

"Say your goodbyes, Bill, because you're already dead." Penn cried.

"Nani?!" Bill exclaimed, as Penn punched him in the face.

"NO!" Bill yelled, "This can't be happening! A-X-O-L-O-T-L! My time has come to burn! I invoke the ancient power that I may return!"

Bill was glitching out.

"PENN ZERO!" He yelled.

Penn punched Bill in the face again, causing him to shatter.

"I can't believe it." Penn said, as his friends returned to normal, "We did it!"

Then, the Dimension Warriors were teleported to what seemed like the center of the Multiverse.

"Where are we?" Penn asked.

"It's been a while, Penn Zero." An old woman said.

"Phyllis!" Penn cheered.

By her side were all of the allies that the Dimension Warriors befriended during their journey.

Then, music played. It was as if the team had entered the Pokemon Champion Hall Of Fame.

"Penn!"

"Boone!"

"Sashi!"

"Tyler!"

"Kevin!"

"Shope!"

"Roach!"

"Kirby!"

"We did it!" Penn said, "Bill's been defeated, and now the multiverse is safe!"

"Now what?" Boone asked.

"It is time to say goodbye." Phyllis said.

"Wait, what?" Penn asked.

"I think she's serious." Sashi said, holding back tears.
