It had been months since Beatrice Flynn learned a terrible truth. That her father, Phineas Flynn had not only created a twin brother for her, but when Beauregard sought to take over Earth, and he was thwarted. Phineas redacted all memory of him from her files.

Not only that, but Beauregard was reactivated in secret by the Vigilant of Ic'thao. Aliens from the future that sought to exterminate humanity, and allied himself with them for his own ends.

Since then, Bea has largely cut herself off emotionally from her family. Unwilling to forgive her father for keeping such a secret from her, and her mother Isabella for her complicity in the matter.

Eventually, however, the Christmas season came. "So... what'cha want to do for Christmas?" Isabella asked of Beatrice one morning.

"I... I dunno." Beatrice said sullenly.

"Bea, you've got two weeks off from school. You must want to do something?" Phineas asked.

"Maybe... but I'm drawing a blank," Beatrice said sullenly.

"Oh, good grief!" Her Human sister, Bethany said in aggravation. "We get it, your upset that mom and dad kept Beauregard a secret! You've been like this for months! Can you please get over yourself!?"

Beatrice glared at her sister. "Familial ties are the only reason I'm not putting you through the wringer for that comment," Bea said angrily.

Phineas and Isabella looked exasperated by this entire situation. "Bea... what is it going to take for you to get out of this funk?" Isabella asked in concern.

"Also, don't threaten to hurt your sister," Phineas added.

"Or what? You'll put her away, and remove any memory of her from me?" Beatrice said coldly.

Meanwhile, on the other side of the galaxy. Beauregard Flynn, along with Sool-Aaris and Monocle-Tron were working on the surface of the ancient planet of Nidavellir. "So... we got everything except for the power source," Beauregard said as he looked over the nearly completed Quantum Android Forge.

"Why was that not constructed first?" Sool-Aaris asked telepathically.

"Indeed, with Doombringer taking over every Auto-Foundery on this planet. It's a miracle that we've managed to make the rest of the QAF without interference." Monocle-Tron said.

"Look, it made sense from my father's notes! And I did my math, and this can only be constructed properly in this specific way." Beauregard said. "Any other way, and we'd instead create a bomb that could blow up the entire universe... and that's a best-case scenario!"

"Very well... let us begin on the Quantum power source." Monocle-Tron said, then without warning the lights in the foundery blinked wildly before exploding and cutting out completely.

"What just happened?!" Sool-Aaris said in surprise.

Later, onboard the Vow of Vengeance, the flagship and mobile headquarters of the Vigilant of Ic'thao. Beauregard met with Doombringer, the leader of the giant transforming robots. With the rest of the VI and there allies attending. "So... let me see if I have this right. You... Burnt out an entire continent?"

"Apparently." Ty'raka said as he looked over a holographic clipboard. "That entire eighth of Nidavellir has been burnt out."

"And it's all because... you repurposed the entire planet to build Cy'tar's for your army?!" Beauregard yelled in frustration at Doombringer.

"Not just warriors. But warships to transport them." Doombringer said, indifferent to the young robot's frustration.

"AND YOU DIDN'T THINK TO AT LEAST WAIT UNTIL I WAS DONE?!" Beauregard roared in anger.

"ENOUGH!" Then, the Eternal King stepped out of a time portal. "Be silent... Doombringer, you have put a vital project at risk. Can you finish it, even with the rest of Nidavellir under Doombringer's control?"

"No... creating the power source is incredibly dangerous. And as I'm certain I don't have to tell you. I don't have the experience to build a new one from scratch without a Nidavellir Foundery." Beauregard said in exasperation.

"Then... I am afraid that for this affair to be settled, there is only one choice. Beauregard... you must go to Earth, and get the Sym'ian's that Ty'raka sent to aid you in acquiring a Quantum power source for the Quantum Android Forge." The Eternal King said.

"What? Why can't you get Ty'raka to do it?" Beauregard said.

"For one thing, the Vow of Vengeance is not going anywhere near that ball of dirt until the time is right. To face your sister on even ground. And for another, the Day of Memory is coming up, and the Ancient Laws say that we cannot dirty ourselves with combat or violence of any kind until the Day of Memory itself dawns." Ty'raka explained.

"Well, why not Doombringer? It's his fault this is an even an issue!" Beauregard said irately.

"We celebrate this day as well. All the more reason why your not just a pile of scrap on the floor." Doombringer said.

"In other words, young Beauregard. Your the only one who can do this. I would do it myself... but Phineas Flynn and his companions have wizened up to my presence. He has managed to create defenses against my people's technology." The Errant King said.

"Impossible! Even our peoples, Yoral, or Cy'tarian have been unable to fully negate the technology of the Spaa-Chrounous!" Ty'raka said in disbelief.

"He also built a robot, and a mech suit that handed you aliens your collective can's despite your superior training and technology. AKA, my sister, and the Silver Automaton armor." Beauregard said proudly.

"All the more reason to send you in." The Eternal King then opened a portal. "This leads to the Sym'ian ship, fortune favor you young Beauregard." Beauregard then went through the portal and found himself on the Sym'ian ship. "Alright, you apes! Listen, and listen good!"

The Sym'ian crew looked at him. "Who the heck are you?" A blue-furred Sym'ian female asked.

"The Eternal King sends his regards. Now listen, very carefully. He wants me to acquire something of importance to his plans. But I need your help to get it." Beauregard explained.

"Okay... what specific kind of help?" The shaved Sym'ian, Nallirk asked.

"That... I haven't figured out yet. I only just got here." Beauregard said, he then went to a computer terminal. "Just give me a moment." He then hacked into the Earth's Internet.

"Well?" Bullama, the Sym'ian scientist asked.

"Patience little monkey. Not drawing Machina's attention will be difficult. Which will be harder considering that this ship is past the furthest body in the Sol System... it's going to take a while." Beauregard said several hours passed as he scanned through online content. "Well... this looks like an opportunity." He said grimly.

"Okay... why don't you look happy about it?" Nallirk asked.

"First off, it's Christmas. Secondly, this mission involves stealing something from my father. Thirdly... thirdly it'll distract my sister. So why should you care you shaved little weirdo?" Beauregard said snappishly.

"I have a rare allergy to my own fur! And... well look I might not know you well. But it's perfectly normal that you don't want to do these things." Nallirk said.

Beauregard scowled. "Just make preparations."

A few days later, Beatrice returned home with her arms filled with Christmas presents. "Well... I finished my Christmas shopping for my friends." She said to herself.

"You walked home rather than flew home, didn't you?" Phineas asked.

"I wore my winter clothes," Beatrice said, not even trying to be defensive. "Now if you'll excuse me, I need to wrap my presents for my friends." She said as she went into the basement lab and over the course of several hours. Wrapped all of the presents for her friends. Then she laid down on the Quantum Android Forge and started to cry. "It's Christmas... why can't I forgive my parents?" She wept.

Then before she could lament further, an alarm went off. "EMERGENCY! EMERGENCY! SYM'IAN SHIP DETECTED IN ORBIT OF EARTH! SYM'IAN BIO-SIGNATURES DETECTED ON THE SURFACE OF THE PLANET: EARTH."

Beatrice's sullenness quickly turned into rage. "Where are they?"

"THE CLOSEST SYM'IAN LIFE SIGNS ARE AT THE NORTH POLE!" The computer said.

"I really got to find your volume controls SAEBS," Beatrice said as she donned her Silver Automaton armor.

Later on, G'reet and Vo-Kaa were shivering in the snow. "Okay... I distinctly remember this place being warmer the last time we were here." Vo-Kaa growsed, then Beatrice in her armor arrived.

"You can thank the minds at PFD Technologies. Since you misbegotten, apes trashed this world. My creator and his associates have repaired the damages you caused and more." Beatrice said. "Which brings me to you two... why are you back?"

"Because you lied to us, Beatrice Flynn!" G'reet said irately. "Your really an infant under that armor!"

Beatrice chuckled heartily to herself. "Oh, please tell me you figured that out yourselves. I'd be the first real credit to your intelligence that I've ever seen."

"Let's just say... a shared associate told us," Vo-Kaa said sinisterly.

"Ty'raka... of course he's still out there," Beatrice grumbled.

"Yes, and under the guidance of the Eternal King. He is mustering a great army to take this world!" Vo-Kaa gloated.

"You know... I didn't even ask what that dinosaur was doing." Beatrice noted.

"The point is, we're taking back this world!" Vo-Kaa said.

"Really?... so you've been training non-stop in the last decade. Instead of mopping across the galaxy about how you failed, and everyone's made fun of you for being kicked off a pre-FTL world." Beatrice said.

"Yeah- NO! I MEAN! YES, WE HAVE BEEN TRAINING!" G'reet said.

Beatrice just rolled her eyes underneath her helmet. "Your flinchy betrays you. So you can either tell me what's really going on... or I'm going to put you monkey's twelve feet under for good."

"I thought the Earth custom was six feet?" G'reet asked confused.

"Yes, but I'm willing to double for your... royal highnesses," Beatrice said.

Vo-Kaa then breathed an aggravated sigh. "Look, we just wanted to get your attention while we took over your moon... where the one you know as Santa Claus has relocated." He explained.

Beatrice clenched her fist in anger. In the ten years since the Sym'ian Occupation, Santa Claus had moved his workshop and his worker elves to the moon. Specifically, the Largest Building on Earth that Phineas and Ferb built when they were children, and thanks to Doofenshmirtz's Lunar-Rotate-Inator was on the opposite side of the moon from Earth.

"You... wouldn't." Beatrice fumed.

"Kid, if we were willing to burn you down to the robo-bones. Would it really be that hard to believe that we'd threaten an old man and his army of midgets?" Vo-Kaa said.

"I wish I was on the moon... it has to be warmer," G'reet whined.

"G'reet, their moon doesn't have an atmosphere!" Vo-Kaa said.

"I know... but they have hot chocolate and sweats up there!" G'reet said, then he and Vo-Kaa flew into the sky.

"BLAST! Why didn't I take the chance?!" Beatrice roared in anger, she then flew after the Sym'ian's.

Eventually, she landed on the moon, on the outskirts of Santa's new Workshop. "-and that's why I'm on the moon."

"All the same, please wait for backup," Phineas said over his daughter's comm channel.

"Dad, it's the same two Sym'ian's I beat to a pulp in this armor. And their merry band couldn't even touch me when I was without." Beatrice said confidently.

"But they might have some new weapon! Or new technology that could tip the balance in their favor." Phineas said in concern.

"They all but admitted that they've been sitting on there laurels since they were driven off. Even with token help from the Vigilant of Ic'thao, I can take them... trust me, dad. I'll be home in time for Christmas." Beatrice said.

"B-But Beatrice!" Phineas pleaded.

"Begining radio silence," Beatrice said as she deactivated the comm channel. "Heh... it's funny because we don't use radio waves anymore." She then made her way into the giant skyscraper and found Santa Claus and his Elves were tied up.

"Your Flynn's girl ain't ya?" An older looking Elf said. "I'm Clewn't, you mind getting us down from here?"

"It's my very reason for being." She said as Beatrice began with Santa's bonds.

"Beatrice, you need to get out of here! It's a-" Santa's warning was interrupted as a purple fist slammed into Beatrice, sending her flying out of the building. "...trap"

Beatrice was dizzy from this, and when she stood up. She saw exactly what punched her. "Oh, you've got to be kidding me." She said in disbelief at the giant spectral monkey that was stepping out of the building.

"Do you like our makeover?" The monkey asked, seemingly speaking with at least six voices. "It took a lot of busywork to uncover the Ritual of Soul Merging. But we... are now ONE! We are the Psi'vatar! Now prepare to fight!"

XXXX

Meanwhile on Earth. Phineas was beside himself. "How... how are we going to get Beatrice to forgive us for keeping Beauregard a secret from her?" He said despondently to his wife.

"I don't know Phineas... but we'll find a way." She said, then as if on cue. Phineas's phone rang.

The caller ID showed it was Santa Claus, and Phineas answered. "Oh thank goodness your there."

"What's going on up there?" Phineas asked in concern.

"Well... it's a bit of a long story Phineas." Santa said shakily. "But those Sym'ian's tied up me and my Elves. Then Beatrice came, I tried to tell her it was a trap... but that Psi'vatar they made cut me off."

"A Psi'vatar?" Phineas and Isabella asked.

"Yes... some sort of gestalt form the Sym'ian's made from there psionic powers. Now all six of them are fused and... well it's big." Santa said in concern.

"How big are we talking here?" Phineas asked in concern.

"You remember those giant robots you got? The one that can turn into a space ship and the other one that requires two-pilots in order to work safely?" Santa asked.

"Technically Titan Beak needs three pilots, two for locomotion and one to manage the advanced weapons system," Phineas said.

"Well, this thing is big enough, that only they have a fair chance of fighting this thing in a fair fight!" Santa said. "It's frankly a miracle that she's still standing at this point.

"Then we have no time to lose. We'll be up there shortly. Just make sure she's alive when we get there." Phineas then hung up. "Isabella, I need you to call up the other BEA-Droid's and Bea's friends. I need to go and get Titan Beak operational." He then bumped into the Errant Traveler. "What the- what are you doing here?"

"Ah... well, you remember how you and Ferb asked me about getting a Cy'tar Ener-Heart for Stellar Imperium?" He pointed out. "Well, it took a bit of work. But I found an Ener-Heart rated for a Cy'tarian Colossus." Then a number of his companions entered the house, carrying the giant green battery.

"You said we were carrying a couch!" One of the alien companions complained.

"Yes... technically my people's word for an Ener-Heart translates to 'a long upholstered piece of furniture for several people to sit on.'" The Errant Traveler's companions looked in disbelief at this explanation. "Yes, I know it's really weird. But that's the honest truth there!"

"Just get it to Stellar Imperium. We'll handle things on our end!" Phineas commanded.

"You heard the man! Back into the Tacho'noma with the Ener-Heart!" The Errant Traveler barked.

Unknown to anyone, Beauregard was keeping a close eye on his childhood home. "The board is set... the pieces are moving... and the game begins in earnest." He said to himself.
