Here's the final obstacle, which will be focused on my OC's choice. In addition, I own no one else, and I own nothing else; just my OC. In addition, the song I put in I also do not own but is a parody of "Stronger than You," sung by Estelle/Garnet and belonging to Rebecca Sugar and her awesome work Steven Universe. Thank you for letting me put in the disclaimers, and enjoy.

The inside of the area looks more tranquil than they expected. It is almost like they've stepped into the Temple of Zeus while it's still young, but the columns looked as though they're peppered with gems. And the floor is marble so well polished that Pam thought it's under a huge pane of glass.

But the great power that stands before them is a sight to behold as well. It looks almost like a giant version of the monstrance that Pam sometimes sees at church, except it's made of glass instead of gold. There are also six orbs encircling a seventh, each of the seven holding swirling energy within with a crystal inside: a red flame; an orange twister; a yellow sun; a green mountain; a blue water droplet; and a violet moon. The seventh one in the middle is a yin-yang.

"This is it, guys," Pam said to them with a smile. "The great power that will help save all of Ponyville."

"Yeah, but…now what?" asked Skrawl. "How are we to use it?" They then thought about it.

"I wonder if…" Jaden said before walking up to the large monstrance. He then held his hand up to the orb with the flame and placed his hand on it…and his Dueldisk started to glow red!

"Nice thinking, Jaden," Nos replied with a smile.

"Yeah, but…nothing else seems to be happening," Chazz pointed out.

"Maybe uno isn't enough," Goth stated. That's when Pam recalled Starswirl's words.

"As you work together as a team, let your hearts be as one."

"Goth, you're right," she said. "One isn't enough."

"It isn't?" the others replied.

"No," she answered. "In the four obstacles before, we had to be a team. This is one is about teamwork as well. All off us have to be holding our hands onto our respective orbs, and that should activate the great power."

"Then what are we waiting for?" replied Pythor.

So as Discord stood at the side to route for them, the others went up to the monstrance. Nos placed his hand on the twister orb, and his Dueldisk started to glow orange. Goth placed his wing-claw on the sun orb, and his Dueldisk started to glow yellow. Skrawl placed his Armorph-hand on the mountain orb, and his Dueldisk started to glow green. Chazz placed his hand on the droplet orb, and his Dueldisk started to glow blue. And Pythor placed his hand on the moon orb, and his Dueldisk started to glow violet.

Pam is now the last one. As she reached out to place her hand on the yin-yang orb…

"DYAUGH!" Hearing Discord cry out, Pam turned around sharply to see him suddenly pinned to one of the columns by black rings glowing sickly green on his neck and arms.

That aura, Pam thought with shock. Oh, no…not her…She turned sharply to the others.

"Guys," she cried, "keep your hands on the orbs!"

"Oh, why don't you just let them do the opposite instead?" a low female voice advised rather coldly. They turned to the front to find the former Changeling Queen Chrysalis standing before them with a sly but arrogant smile.

"Chrysalis!" Pam cried, activating her Dueldisk and holding her other hand up to the last orb. "One false move, and I'll touch the last orb!"

"You know that old hag?" Skrawl asked, his hand still on his orb.

"Who are you calling a hag?!" Chrysalis demanded angrily.

"She's a has-been enemy of Equestria wanting to conquer it all," Pam answered. "She's obviously here to stop us from activating the great power like Starswirl warned us." Chrysalis only smiled at her softly.

"Actually, I'm here to stop you from making the worst mistake of your life," she explained calmly. Pam glared at her suspiciously.

"What are you saying?" she demanded.

"I'm saying that Starswirl hasn't been fully honest with you, Pam," the Changeling stated. "Don't you know what will happen if you activate the great power?"

"Duh," Pam replied with an unconvinced roll of her eyes, "all those Monsters trying to attack Ponyville."

"Well, yes, that," Chrysalis replied. "But if you also activate the great power…" She then gave her a half-lidded gaze. "You won't be able to go home." Pam's angry glare fell to shock.

"Wh…What?" Chrysalis only smirked at her.

"That's right, Pamela," she stated. "The great power is your key to returning to your world. As long as it says inactive like it is now, you can still get home. But if you use it on those Monsters attacking Ponyville instead, you'll lose your chance and be trapped here in Equestria forever."

"Don't listen to her, Pam!" Pythor cried to her. "She's obviously trying to trick you! If you go home, Ponyville's done for!" And yet Pam can't stop but pay attention to Chrysalis with growing sorrow.

"How else will you be able to return home, Pamela? Think about everyone in your world you've left behind…your friends…your family…your—OW!"

Pam blinked with surprise when something struck Chrysalis close to her eye, nearly poking it out. Looking down at the floor, she saw it's a chocolate wafer straw. Chrysalis turned to Discord, who's obviously the one who threw the straw at her with his tail.

"Just ignore her, Pam," he said to her smugly despite his current situation. "She obviously stinks at lying far worse than a skunk." Chrysalis was ticked off at that insult.

"Me?!" she demanded like an immature brat. "You're a liar too!"

"Used to," Discord corrected her. "And unlike you, I've been reformed and made some friends. I swear, you're such a bratty little sister."

"Bratty lit—YOU'RE NOT EVEN MY REAL BROTHER!"

At those words, Pam immediately snapped out of it. She saw Mel through Chrysalis' enraged expression…and remembered her words from their fight that led her here.

"YOU'RE NOT EVEN MY REAL SISTER!"

Discord was right…Chrysalis had to be lying to her…Her family had lied to her, after all. So with the Changeling distracted, Pam turned and placed her hand upon the yin-yang orb, causing her Dueldisk to glow rainbow colors. Then the monstrance started to glow with a white light. Sensing it, Chrysalis turned to the seven heroes with dismay.

"No…NO…NOOO!" At her cry, a rainbow-colored pulse erupted from the great power and across/up from the subterranean. It spread throughout Ponyville above. And when it struck the Monsters, they glowed white before shrinking into harmless cards that fluttered down towards the surprised Ponies coming from feeling the warm pulse.

Back at the subterranean, the light vanished, and so has the monstrance. The seven heroes stood in its place.

Jaden's black turtleneck has become crimson, and a flame-patterned cape is attached to the back of his jacket's collar.

The red parts of Nos' body suddenly grew brighter into persimmon, and his cape has been replaced with a wind-patterned one.

Goth has on a goldenrod breastplate on his torso like a conquistador, and attached to the shoulders is a sun-patterned cape.

Skrawl has two viridian bands (one tied around his head like Rambo, and the other around the upper bicep of his Armorph), and the string of his leaf-patterned cape is hitched together on the shoulder of his Armorph.

Chazz's jacket's open to reveal a cerulean turtleneck underneath, and a water-patterned cape is attached to the back of said jacket's collar.

Pythor has on a lavender gi, and attached to the shoulders is a moon-patterned cape.

Pam has changed the most of course. Her denim jeans with white sneakers have been replaced with onyx leggings and ivory knee-high boots. Her black shirt and black pleather jacket have been replaced with a pearl turtleneck under an unzipped vest that looks to be made of sequins of opals. And instead of a cape like the guys, she has on a pastel-colored silk scarf and ivory fingerless gloves. And her glasses are gone.

Once her vision had cleared, Chrysalis turned and saw that the seven have changed because of the great power, much to her shock and dismay.

"Hey, Chrys!" Discord mocked with a laugh. "Don't look now, but you just got your flanked whooped again…This time, by a human! Ha-ha-haaaa!" Chrysalis only ignored him as she scowled at Pam, obviously ticked off as she is chagrinned.

"Are you serious?" she growled. "You couldn't get back home if you activate the great power, and chose to do it anyway? Why? I know you well enough considering I know your name." Pam only laughed at her softly, upsetting her more that she doesn't believe her.

"You're wrong," Pam then said with a gaze that's reminding Chrysalis that she's lost. "You don't know me well enough, and you don't know my friends either. We're different now after coming together."

"How would you know?" Chrysalis spat.

"Because if that weren't true," Pam answered, "you would've won. But the reality is you have lost…to seven new and improved knights."

Pam: We're the Duel Knights

Here together

And we're never going down

To the likes of you

'Cuz we know far better

And every part of us

Is saying, "Go beat her!"

Chrysalis only scowled at Pam and the others smirking at her as they would at a sore loser. They're not going to get away with making a mockery out of her. So with her horn's magic, she summoned forth a black scythe with a sickly green blade.

Pam: My boys and I

We'll never follow your rules

Come at us without

Any of your lame-o tools

Let's face it

We know you're through

So let's go

It's us versus you

Pam only smiled before snapping her fingers by her eyes, and a pair of onyx sunglasses appeared in front of them. Chrysalis then charged at the group to slice them with her scythe, but they dodged it. As the Changeling tried to beat them, Pam and the boys kept on mocking her via song, making her unable to think straight.

Skrawl: Go ahead and try to beat us

If you're able

Nos: But you'll see that our bond

Is now more stable

Goth: I see you hate us

Saving everypony

But I think you're ticked off

'Cuz you're lonely

Because of this, Pythor knocked the scythe out of her magical grip with is tail and into Skrawl's Armorph hand. The Zoner then broke the weapon in half like a twig before tossing the blade half up to Nos, who flew up to Discord and used the blade to cut the rings and free him. As Discord flew off to check on Twilight, Starlight, and the others, the enraged Chrysalis spread out her wings and charged at the knights, who also charged at her.

Jaden: But you'll never stop

What we made together

Chazz: We're gonna stay

A team forever

Pythor: You can't break us apart

'Cuz we'll be back newer

Pam: And we'll always be

Better Duelists than you are

Meanwhile, the Ponies in the castle sensed that Pam and the others have found the great power and rushed for the subterranean.

Pam: We're Equestria's

Du-u-u-uel Knights

Du-u-u-uel Knights

Du-u-u-uel Knights

They had just entered what used to be the first obstacle when they saw Discord rushing up to them.

Pam: Du-u-u-uel Knights

Du-u-u-uel Knights

Du-u-u-uel Knights

"Discord," Twilight said when they got closer together. "Where are Pam and the others?"

"They're in the last room fighting Chrysalis," he panted, trying to catch his breath.

"Chrysalis?!" they cried in shocked unison.

"Why didn't you say so sooner?!" Shining cried, rushing past the Draconequus.

"I just did," Discord called back before they rushed after him.

Pam: This is who we are

This is who I am

And if you think you can beat us

Then you better rethink your plan

Because we are a team

And I won't let that end

And we won't let you have Ponyville

And we won't let you hurt our friends

Back with Pam and the guys, they are mopping the floor with Chrysalis. Completely outnumbered seven to one, every time she one of them, another of the team attacks her from her blind side. It wasn't long before Goth's summoned Ferus Arcus cracked her horn with his bow and arrow, close to shattering it.

Skrawl: Go ahead and try to beat us

If you're able

Nos: But you'll see that our bond

Is now more stable

Goth: You think we're something

You're not scared

'Cuz you think you see

What we're made of

Chrysalis then took flight and nosedived to impale Pam with her cracked horn, but the girl grabbed it and judo-threw her. Her horn broke off and she ended up crashing into the now empty monstrance, shattering it into hundreds of beautiful crystal shards.

Jaden: But we're more than

Seven knights

Chazz: All we love makes us

Fight for right

Pythor: We are one yin

'We are one yang

Pam: We are one family

As she stood up from the shards, the team then finished her off, one blow at a time from their summoned Monsters, which are stronger because of the great power. First was Chazz with his Ojama King; second was Nos with his Vampire Lord.

Pam: We're Equestria's

Du-u-u-uel Knights

Du-u-u-uel Knights

Du-u-u-uel Knights

And we're stronger than you

Third was Jaden with his Elemental Hero Flame Wingman; fourth was Skrawl with his Jinzo.

Pam: Du-u-u-uel Knights

Du-u-u-uel Knights

Du-u-u-uel Knights

And we're stronger than you

Fifth was Goth with his Ferus Arcus; sixth was Pythor with his Hyozanryu.

Pam: Du-u-u-uel Knights

Du-u-u-uel Knights

Du-u-u-uel Knights

And we're stronger than you

Pam was last with her Seiyaryu. Unable to take another beat-down, Chrysalis collapsed and was down for the count.

Pam: Du-u-u-uel Knights

Du-u-u-uel Knights

Du-u-u-uel Knights

Discord, Spike, and the Ponies rushed into the room. All they found were the Duel Knights in their new looks, a beaten down Chrysalis, and Pam holding the Changeling's cracked horn in her hand.

"Aw, man!" Rainbow cried with dismay. "Don't tell me we missed the fight!" The Duel Knights turned to her and the others.

"Sorry to say this, Rainbow," Jaden said with a shrug, "but…yeah, ya did." Rainbow groaned/whined in reply as Rarity went up to Pythor.

"My stars, Pythor," she stated. "That cape is definitely you."

"Oh, you think so?" he asked, checking it out. "I always thought I was more of an eminence until I got it." Shining Armor meanwhile went up to Pam's side, glaring hostilely down at Chrysalis.

"What is she doing here?" he demanded. Pam can tell that he's holding quite the hostile grudge against her for what she almost did to him…to his wife Cadence…and to his daughter Flurry Heart.

"Apparently, she was trying to trick me into not activating the great power with the guys," she answered bluntly, crossing her arms across her chest as she also glared down at the defeated has-been queen. "But I chose to activate it anyway and help the guys beat her." Shining then turned to him with a calmer smile.

"Well, thanks to you seven, Ponyville's safe again," he assured her. "And don't worry; we'll make sure she receives the upmost punishment." While they're not looking though, Chrysalis took out a blue vial with her tail.

"That's what you think," she snarled. That remark made Pam and Shining turned to her…just as she slammed the vial into the ground. It shattered with a SMASH and released a cloud of blue smoke so huge that it filled up the room. Pam staggered back as she and everyone else started coughing and sneezing.

"What is that?!" Nos cried. "I can't see anything!"

"Smoke bomb!" Skrawl coughed.

"Hang on," Discord called with a sneeze. "I got this." There was suddenly a loud whirring sound before the blue smoke disappeared into a vacuum cleaner that the Draconequus conjured up.

"Nice work, dude," Jaden replied with a smile. "That's one way to help someone with allergies."

"Guys, she's gone!" Chazz cried. They all saw that Chrysalis has indeed vanished. They even spotted a hole in the ceiling of the room to indicate her escape.

"Darn it!" Shining growled, slamming his front hoof into the floor (not cracking it, of course). "She got away again!"

"Don't worry, Shining," Pam said to him, looking down at the Changeling's horn still in her grasp. "I've a feeling we'll be seeing her again."
