Something to change everything

Bad Guy was startled when he was suddenly teleported but given a look around makes him realize what just happened, "Why am I... in a final boss arena?" Bad Guy asks as human Sweetie Belle appears and laughs.

She looks at Bad Guy and drops the sinister face as she gives him a hug, "We're alone... oh... how wonderful, isn't it? I'll take care of those pesky heroes for you," she said as she looked at his face.

Bad Guy sighed and moves human Sweetie Belle's hair and sees his eyes in her, "Heh, you got my eyes," Bad Guy said as he properly returned the hug, "Man, you know what they say, kids grow up fast. How's your mother? Still a naivé idiot?" He asked.

Sweetie Belle let the hug go, "Is there anyone in this city that isn't an idiot? Well... aside from you," she said as Bad Guy chuckled.

"True true, I forgot how stupid the people of this place are. But... you didn't have to kidnap me, kid," Bad Guy said.

It was Sweetie Belle's turn to chuckle, "I knew that, but it was more fun seeing Tamer get all pissy because I stole you," she replied. The two just looked at each other, before Sweetie Belle sighed, "You've been out of my life nine years, I saw you once during those nine years. Everyone always said that it was no good trying to find you since you were, and I quote, 'a huge piece of shit.' But I wanted to find you regardless of how much of a piece of shit you were," she said as Bad Guy smiled.

"Aww, got my personality too, but we both know that flattery doesn't save someone from a villain," Bad Guy said as he ruffled Sweetie Belle's hair, who just giggled in response.

Meanwhile, with the heroes and Tamer Sweetie Belle...

Sweetie Belle and Batty had just killed another enemy in pure rage, the enemy was somewhere in here and they were going to save Bad Guy if it killed them! "Sweetie Belle!" Twilight said, causing Sweetie Belle to snap her head in Twilight's direction in pure anger. "There's a puzzle this way but none of us can figure the answer so we thought you might know it," Twilight said as she went down a hallway and Sweetie Belle followed.

The room had everyone in the party staring at the puzzle and Sweetie Belle knew the answer since she'd seen the exact puzzle in Bad Guy's base, "Ahem, 'For every ounce of kindness, there is a gallon of darkness, and for every gallon of darkness, there are ten gallons of evil,'" Sweetie Belle said and the door opened, "Before you ask, Bad Guy had the exact same puzzle in his base, out of reach of you since the solution required knowledge none of you'd have," she added before she and Batty ran forward.

"Okay... yep, I remember the last time she got mad at me and that was still tamer than her anger now," Jacob said earning a look from Dan, "Seriously a good idea to leave Bad Guy alone unless you want to incur Sweetie Belle's wrath."

Jacob, Brendan, Twilight, and the remaining CMC members hurry forward leaving Dan alone. "I can't believe a child could actually grow to like Bad Guy, he's the biggest piece of shit ever," Dan said as he got moving as well. Next were three doorways, each one having a symbol on it. "Bad Guy did this same thing where we had to go complete a mini dungeon based on our own experiences, but why three doors? Why not four or five?" Dan contemplated as he entered his door.

Brendan and Jacob entered their door with Scootaloo and Apple Bloom. Leaving Twilight and Sweetie Belle to enter their own door.

Me and Sweetie Belle looked around the area and saw Ponyville, well... if it was heavily compressed but that didn't matter as Sweetie Belle took off yet again.

Remind me to never piss her off because doing so is literally playing what Bad Guy'd call 'Russian Roulette.' Regardless, I could tell Sweetie Belle was still pissed off beyond compare and said nothing to avoid pissing her off enough fpr her to just murder me. Outright. She actually is thinking about murdering me but is restraining herself.

Following Sweetie Belle, we saw puzzles related to our adventures, trivia related to Nightmare Moon, a sliding tile puzzle picturing Chrysalis' form, moving a Crystal Heart shaped light source to make a Sombra shaped shadow. Frankly, the puzzles were fun and I wish Pinkie Pie could see them... maybe I can ask Bad Guy if he could make a sort of magical door which changes the contents based on who opens it that anypony could use since it could allow for a nearly infinite possible number of puzzles... and since I know he likes getting something from it... maybe he could charge to allow them to enter the door?

Just an idea. Albeit, a mildly scary one. Me and Sweetie Belle found the exit door with minimal opposition so we left this room.

Meanwhile... with Brendan and co...

Brendan slammed his mouse on the new version of the Computer enemy called Computer ++... real creative. "Okay, that should be the last of them, crazy to know that enemies can go beyond + in teiring," Brendan said as everyone murmured in agreement.

"Ah hafta admit, this house is kinda nice," Apple Bloom said as Jacob opened a window and found the mini-dungeon was just as bad as the real thing.

"Yep, still trapped in the middle of fucking nowhere but hey, at least we don't have much shit to fuck up," Jacob said as he closed the window. Brendan chuckled.

"Aw yeah! Adventure time is really gettin' good!" Scootaloo said as she found a puzzle and immediately noticed a pattern in it.

Brendan approached the puzzle himself and looked deep in thought, "'For one who is real, what was the name of the brother associated with teal?' Hmm... wait... Matthew!" Brendan announced as the wall broke door reveong the sleeping 6 six old, well shit, guess I gotta carry him so he doesn't cry upon waking up," Brendan said as he picked Matthew up and put him on his back.

"Ya'll had another brother?" Apple Bloom asked as Brendan and Jacob nodded.

"Yeah, I didn't want to mention Matthew since he just wanted to get back home and so... we let him. Me and Jacob had so much fun on our adventure that... we... didn't go home. We were fine not being there... but now the Sour has really fucked up," Brendan said as the group went forward. Jacob seemed to share Brendan's anger.

A few more puzzles and now the group was exploring an amalgmed version of Diamond Tiara's basement, the Temple of Memories, and Bad Guy's base, "Definitely seems like the Sour loves the memories you've formed," Scootaloo said before killing a + version of a jackalope. Jacob got excited as he killed a Money Bag +.

"Be careful, remember we'll have to fight enhanced versions of all of Bad Guy's troops, most likely of the ++ variety since when we first explored Bad Guy's base, it was full of + enemies. At least the new + versions are cool looking," Brendan said.

Brendan and Jacob solved the familiar puzzles and puzzles related to stuff they didn't see or live through were done by the ponies. Eventually finding the end where they see the memory Bad Guy sitting in his throne, "So you have made it, seems even my strongest couldn't defeat you... whatever. I shall do it myself if nothing else can!" He said as his skin turned blue and his hair turned purple. He started the battle with a laugh following with Antagonistic Dash but it wasn't long before the saw the real threat. Bad Guy's skin has turned bright red and his hair is now a vibrent pink, his outfit has also undergone a change to include a masssive cape.

"Bad Guy's revenge, even the Ultimate Trimmer would fail to defeat Bad Guy as he is now, it might be benefitual to give up," Jacob said from his Observationalist ability.

Apple Bloom rolled her eyes though, "Give up? What are we? Pussies? Not last ah checked," Apple Bloom said as she struck Bad Guy with her whip, "And Brendan, stay outta the fight considerin' yer situation," she said causing Brendan to sigh and go have a seat out of the combat.

Brendan couldn't believe it, a new fight and he has to sit out to protect the still sleeping Matthew. Matt stirred slightly from the noise and Brendan comforted him, "Shh shh shh shh shh, it's alright Matthew, just stay asleep and everything will be over soon," Brendan said but it did nothing as Matthew awoke and looked not scared... but shocked.

"Great, not home anymore but now I can help out!" Matthew said as he pulled out his sword, lovingly called The End, and stabbed it into the ground, summoning many pillars of fire, "Hey big bro, got room for one more party member?" Matthew asked as the fire finished Bad Guy's revenge.

Brendan looked at everyone else who looked conflicted but Brendan looked back at Matthew, "Of course we do! The whole trio's back together!" Brendan said aloud!

Exiting their room, the party of five reunites with Dan, Twilight, and Sweetie Belle, "Oh, we're finally ready to move on! One battle... one battle's all that stand's in the way of victory. Speaking of, welcome to the team Matthew, I am Twilight Sparkle and the little pissed off girl here is Sweetie Belle," Twilight said as Sweetie Belle nodded and then ran into the final room.

"She still hasn't calmed down? And I thought Jacob was bad with his anger sometimes," Brendan said.

"It isn't because it was anybody... it's because it was specifically Bad Guy who was stolen, anyone else and she probably would have been less angry for less time," Scootaloo said as she and Apple Bloom followed Sweetie Belle's example.

"Hold it, Bad Guy's on our side now?" Matthew asked.

Twilight shook her head, "It's... complicated. Like, he is but he isn't. He's only on our side if Sweetie Belle is involved and disinterested otherwise, without compensation," she said.

And everyone was now entering the final room... "Now or never," Dan said.

Bad Guy was just lying on his side, watching human Sweetie Belle tell animated stories about her manipulations and thievery.

Then they heard the door open. "Eh, seems like the heroes caught up to ya. Hey, mind doin' me a favor, kid? Avoid killing them if you can, one of them is actually my friend," Bad Guy told his daughter as she nodded and flew up.

"I'll do you proud, dad," human Sweetie Belle told Bad Guy.

"Let Bad Guy go you fucking... bitch...?" Tamer Sweetie Belle said as she entered the room and realized that Bad Guy wasn't tied up or locked up... he was just lying there. Apple Bloom and Scootaloo entered the room next and were equally as confused as Tamer Sweetie Belle. Then Twilight and the others entered the room and were just as confused.

"Hey everybody, guessing you all have questions about my situation, well... let's just say I connected with someone I had purposefully abandoned because I'm just built different. Nah, basically found out that this world's counterpart to Sweetie Belle is my child that came about because of a one night stand and then proceeded to never see like the piece of shit I am," Bad Guy explained, dropping the jaws of everyone except human Sweetie Belle, "That's the expected reaction, guess you could say evil runs in the family isn't that right... dad."

The wings and green hair of Good Guy appeared, "So you sensed me, figured. It does seem I have a grandchild even if it seems the linage I started will never die," he said.

"Now, if you don't mind, let my daughter have fun, she's been waiting to have her father watch her do something like this," Bad Guy said as he watched the two sides clashing. He was happy, someone was willing to try and finish what he started. Someone to carry his bloodline farther.

Everytime it seemed like his daughter was going to win, something always turned the tables. Then she lost. "I... I lost... I... I'm sorry..." human Sweetie Belle said, tears starting to well up.

Bad Guy came up to his daughter and gave her a much needed hug. "Hey, kid, wanna know something? You did so damn well, I'm proud that you even attempted that even if it didn't exactly... work out," Bad Guy told his daughter as Bad Guy started unknowingly sprouting wings. Everyone present watched in awe at the sight. "You know, you're a real sour kid. Hardly an ounce of sweetness if you, so why don't I call you Sour Ball? Far better than Sweetie Belle and actually allows me to tell the two of you apart by name," Bad Guy told human Sweetie Belle... who smiled widely and hugged him tighter, "I'll take that as you liking the name."

The day continued with Sour Ball fixing the mess she had made and sending everyone off on their ways... "Kid, keep up the good work, remember, I'm never far off," Bad Guy said as he stood in front of the portal.

"Dad... I just got you and now you have to leave me... you know... Mom sent a message asking to see you before you left and while I don't care much whether you do or don't due to jow much of an idiot she and my sister are," Sour Ball replied. Bad Guy sighed... it was time to face a face he had intentionally avoided.

"Got it, I'll... I'll pay her a visit right now... Equestria can wait," Bad Guy said as he used his dark teleportation.

Bad Guy looked at the other end of the room. Cookie Crumbles was looking at him like she expected him, "You're really bad... you know I've been waiting for you to return," Cookie Crumbles said.

"Crumbles. I'm sure you know what our daughter did," Bad Guy replied.

Cookie Crumbles gave a slightly sad chuckle, "I know... she always was more like you and... I'm proud of her as much as you are... because she chose her path instead of letting others choose it for her," Crumbles said.

"Heh, yeah. Look Crumbles I'm... not planning on staying... Sour Ball has you and... well... she's grown up wonderfully without me," Bad Guy said.

Cookie Crumbles was sad Bad Guy was planning on leaving again but... she couldn't stop him. "What if I let you take care of her on the weekends? She doesn't need me and Hondo Flanks holding her dream down. Her dream of being just like her father," Crumbles said getting a thoughtful expression from Bad Guy. Any normal person would assume he was going to ask for what he would get out of the deal... but Crumbles knew... Bad Guy didn't want anything more than offered and was just thinking of if he was going to take it.

"Know what? That sounds fine by me, weekends are usually the most annoying for me anyways due to how irritating ponies are sometimes," Bad Guy says, "But you're telling Sour Ball, I'm not telling the kid as it's a surprise considering the weekend's... tomorrow."

Cookie Crumbles nodded, "Sounds good, I do hope you'll visit me occusionally, Bad Guy, Hondo has been eager to meet you," she said.

"I'll... think about it," Bad Guy said as he teleported off.
