The Isekai Quartet Cartoon Universe

Subaru Natsuki was staring at the Owl House and the Mystery Shack in confusion.

The Goddess Ishtar and Mayor Glossaryck were debating what to do with Steven Universe.

"We need another Magic Teacher, hold everything, Eda Clawthorne is getting married at the Mystery Shack today!" Mayor Glossaryck proclaimed while reading the Newspaper.

Major News: The Time Baby Resurrects the Time Lords, Princess Star Butterfly goes missing!

"I'm sure that Queen Moon Butterfly would love to know how I found Star Butterfly!" Mayor Glossaryck proclaimed next.

"This can't be right, Star Butterfly's Timeline has changed itself!" Mayor Glossaryck declared in sudden horror.

"What are you talking about?" The Goddess Ishtar asked curiously.

"Star Butterfly killed Toffee, the Lizard General, I remember it happening beforehand! It's no longer in the History Books! The past is getting worse without it happening!" Mayor Glossaryck proclaimed.

"Hello irony, guess who's back?" Bill Cipher declared.

"Charming introduction, Bill." Toffee says.

"Why are you summoning me? I told you about the Whispering Spell already." Bill Cipher ponders thoughtfully to himself.

"Princess Star Butterfly has gone missing." Toffee explained the problem.

"You Lost Star Butterfly? How did you even manage that?" Bill Cipher asked suspiciously.

"You don't know!" Bill Cipher yelled in complete disbelief.

Bill Cipher looked across history worriedly.

Meteora Butterfly and Eclipsa Butterfly were taking power away from Queen Moon Butterfly.

Removing Star Butterfly left Eclipsa Butterfly's Fate within Bill Cipher's Hands.

Bill Cipher scowls feeling annoyed.

"We need to Free Eclipsa." Bill Cipher told Toffee the Lizard General pointedly.

Bill Cipher took his only option, Help Eclipsa and use the confusion to his own advantage afterwards.

The Magic Wand was with Star Butterfly, meaning that creating another one for Eclipsa would go undetected if she was still there.

Eclipsa Butterfly was gone with Meteora Butterfly rising to power unchecked, Bill Cipher's Entire Plan was ruined instantly.

"Alright, New Plan, Planet Earth... Human Pawns, who would be useful" Bill Cipher tells himself thoughtfully.

"Hello, Sabrina Backintosh, Cheerleader, 14 Years Old Student of Echo Creek Academy. I'm Bill Cipher, you have been chosen to save the world today."

Subject Name: Sabrina Backintosh

Species: Human Female

Age: 14 Years Old Teenager

Current Magic Teacher: Bill Cipher the Talking Triangle

Current Power: Magic Transformation

"So how do we do this?" Bill Cipher asked himself worriedly.

Star Butterfly goes missing and suddenly Bill Cipher feels nervous.

Meteora Butterfly Conquers Gravity Falls? Nobody Conquers Gravity Falls Before Bill Cipher Does! His entire plan to Get Sixer's Knowledge would backfire if he died beforehand.

Stanford Pines and Stanley Pines were both dead inside the future, Bill Cipher needed to understand why.

Once Gravity Falls disappeared, Bill Cipher ponders who was behind it happening and what their objectives would be.

"The Time Baby is unconscious! The Time Lords are back?" Bill Cipher realized in sudden horror.

The Rick and Morty Dimensions were being pulled into another Dalek War.

"Rick and Morty... Useless Dalek Bait, I'm doomed without better help!" Bill Cipher declared frantically.

The Goddess Ishtar and Mayor Glossaryck were debating their next move.

The Rick and Morty Teams were getting slaughtered.

Nobody thought the Daleks Hunting Rick and Morty down would ever happen, it dumbfounded everyone who thought they were unstoppable beforehand.

Pulling Star Butterfly into the future only got Bill Cipher panicking about the Daleks, it didn't help them.

"Well, Bill Cipher noticed something was going on." Glossaryck says hopefully.

"Bill Cipher is your plan for Defeating Daleks?" The Goddess Ishtar asked.

"Do we have another choice?" Glossaryck asked back.

"This will not work!" The Goddess Ishtar protested.

"Maybe it will do some good before the Daleks kill everybody, probably get someone better to fight the Daleks for us afterwards." Glossaryck says hopefully.

"Milo Murphy asked the Time Baby for help and the Daleks invaded." The Goddess Ishtar reminded him.

"The Time Lords and their Time War got pulled into our dimension, it probably was an accident." Glossaryck says worriedly.

"Rick and Morty are hiding while the Daleks are invading entire dimensions unchecked, why is Bill Cipher suddenly our only hope?" The Goddess Ishtar asked.

"The Time Baby's Army will be destroyed otherwise, we need options, we need Bill Cipher fighting the Daleks instead of us." Glossaryck explained.

Bill Cipher started checking alternate reality versions of himself telepathically.

The Daleks were killing him repeatedly to Enslave Humanity.

Several dimensions where Bill Cipher Conquered Gravity Falls only for the Daleks to murder him afterwards dumbfounded him.

Curse Murphy's Law and the Daleks invading!

Bill Cipher floated around the room nervously.

"I need help, the Daleks are smarter than the Humans. Somebody better than Rick and Morty... the Time Lords distrust me, who else? The Lovecraft Gods, the Cthulhu Collective maybe useful." Bill Cipher debated.

Sabrina Backintosh was asleep, unaware of her new life inside the Mewni Farming Community outside.

"I don't fully believe the Time Baby needed the Time Lords to Save Milo Murphy, I wonder what really went wrong?" Bill Cipher debated.
