A/N: And here it is, the final arc of this story. Thanks for sticking around, everyone. I'm going to try and give this the awesomest ending possible.
––
Pikachu's footsteps echoed throughout the room as he cautiously stepped into the Temple of Time. He was getting very nervous, and the eerie chanting in the background music wasn't doing much to calm him down.
"Man, I can't believe we really have to fight Mewtwo. I thought this day would never come," Togetic sighed. I'll be frank, I'm not too optimistic."
"Aw, c'mon, T-money! I'm the Hero of Time! We have to win!" Pikachu assured her, turning to look at her and promptly crashing into a wall as a result.
"It's official. We're gonna die. This is the worst day ever."
"I've been waiting for you, Pikachu," came a voice from behind them. They turned around to find Absol standing in front of the temple entrance.
"HOLY CRAP! THIS IS THE BEST DAY EVER!" Togetic shrieked in joy, zooming over to him only to violently jerk to a stop as she strangled herself on the collar around her neck.
"Sorry man. I thought she might do that, so I put a leash on her," Pikachu said to Absol.
"I'm still trying to figure out how you got that on me without me realizing it," Togetic grumbled.
"…Right," said Absol, who would have been more weirded out by this scene if he didn't already know Pikachu and Togetic very well. "Now then, Pikachu, I'm sure you realize that your final showdown with Mewtwo is about to begin. I can't stress how important this is, and although it's probably beyond your brain capacity I need you to take it seriously."
"The hell, man? I'm completely serious!" Pikachu fumed as he scratched his butt and belched loudly.
"…But before you go off to fight him, there are some things that I need to tell you and only you."
"WHAT ABOUT ME? CAN YOU TELL THEM TO ME?" Togetic cried frantically, jumping up and down and flailing her arms while Pikachu spaced out and picked his nose.
Absol's eye twitched. "BOTH OF YOU, STOP BEING IDIOTS RIGHT NOW! WORDS CANNOT EXPRESS MY UNDYING HATRED OF BOTH OF YOU!"
Togetic frowned. "That's mean."
"Oh, he's joking. Everybody loves us! Even that angry mob that chased us over here!"
"If I can get on with my story?" asked the extremely weary and long-suffering Absol. "Now Pikachu, the first thing you must know is that Mewtwo does not have the entire Triforce. Part of the legend states that if a person whose heart is out of balance lays their hands on the Triforce, it will split into three parts representing Courage, Wisdom and Power. Mewtwo only received the Triforce of Power, which represents the force he believes in the most. Maybe you should write this down, Pikachu."
"Yeah, yeah." Pikachu was quickly scribbling stuff down on a notepad. "So the most sacred and powerful relic that forms the entire backbone of our very religion and existence got shattered by somebody touching it. That makes no sense at all, but literally nothing else in this world does either."
"And there's something else," Absol went on. "When the Triforce was broken, the two remaining pieces, Wisdom and Courage, also went to the two people who best embody those traits. Mewtwo cannot hope to obtain true power unless he finds those two people."
Pikachu perked up. "Ooh, really? I bet I got the Triforce of Wisdom, didn't I?"
Togetic promptly went looking for a body of water to drown herself in.
"No, Pikachu. But unfortunately, you did receive the Triforce of Courage. Not because you're brave, but because giving you the Triforce of Wisdom would have created a world-destroying paradox akin to dividing by zero."
"Ah."
"And of course, the bearer of the Triforce of Wisdom," said Absol, "is the seventh Sage, who is destined to be the leader of them all…"
Suddenly, Absol held out his front paw, and a bright glowing Triforce symbol appeared on the back of it. Pikachu and Togetic stared at it awe (Pikachu was mainly entranced by the shininess), when suddenly the glow became blinding and a brilliant flash lit up the room.
When the light died down, Pikachu and Togetic opened their eyes… which promptly bulged out of their heads.
Standing in Absol's place was a very familiar small brown Pokémon. She was seven years older and fully grown, but there was no mistaking who it was.
"It is I, Eevee, the princess of Hyrule."
There was an extremely heavy, tension-filled silence. Pikachu glanced over at Togetic and saw the look on her face, then got nervous and quickly sidestepped away from her.
Eevee noticed this as well and sighed. "Hoo boy…"
"YYYYYAAAAAUUUUUGGGGGHHHHHHHH!" Togetic screamed. She ripped off her collar, threw herself at Eevee and tackled her to the ground, then grabbed her by the head and started repeatedly bashing it into the floor.
"YOU STUPID B#TCH! ALL THIS TIME I THOUGHT YOU WERE A SEXY HUNK OF MAN AND NOW YOU TELL ME IT WAS ALL A LIE? I'M GOING TO #*?&ING KILL YOU AND THEN RIP YOUR EYEBALLS OUT AND USE THEM TO PLAY TABLE TENNIS!"
"T-money, don't! You can't beat up a princess! We'll get sued!" Pikachu cried, running over and prying her off of Eevee. She lay curled up on the ground while screaming incoherently and foaming at the mouth while Eevee reluctantly got back up.
"Well, she took it much better than I thought she would. Pikachu, I'm sorry I had to deceive you all this time, but it was the only way to avoid being captured by Mewtwo."
"But he's Psychic. Don't you think he'd be able to see past a plain old disguise like that?"
"Shut up. Now Pikachu, you remember that day seven years ago when Mewtwo attacked Hyrule Castle. I remember seeing you there as I fled with my attendant, and I entrusted the Pokéflute of Time to you. I'm not really sure why anymore, probably because I had been sniffing paint earlier that day."
"I love doing that!" Pikachu said cheerfully.
"I'm sure you do. But the point is, our efforts were in vain and Mewtwo was able to follow you into the Sacred Realm. He obtained the Triforce of Power and became the great evil king, and he won't stop until he has pried the two remaining Triforces from our cold dead hands."
Pikachu said nothing.
"That's a bad thing."
Pikachu blanched. "Crap."
"But that's not going to happen, because you and I are going to defeat him, Pikachu. You go and do whatever it is that's gotten you this far without dying horribly, and then the six Sages and I will banish Mewtwo back into the Sacred Realm forever. This is an incredibly difficult spell that requires the blood of a hundred virgin sacrifices under the full moon, so please don't screw things up."
"Well, I can't make any promises, but…"
"In order to penetrate Mewtwo's defenses, you'll need this," Eevee concluded, causing Pikachu to snicker at the word "penetrate". "It's the TM for Thunder, the most powerful Electric attack of all. With this combined with the Light Ball, you should be able to bring him down."
Eevee then lifted up her arms, and in an unnecessarily flashy glowy sequence, the TM appeared in the air over their heads and floated down to Pikachu.
"Dude! This is so awesome!" he cheered as he grabbed it. "I'll be an unstoppable killing machine now! I'm going to cause so much completely pointless destruction!"
"Yes, I know, which is why giving that to you goes against every fiber of my judgment. But we should still be all right, just so long as Mewtwo hasn't been listening in on us this entire time."
"Mwa ha ha ha haaaaaa!" came a disembodied laugh that belonged to Mewtwo.
Pikachu stiffened. "That disembodied laugh belongs to Mewtwo!" he gasped, making the previous statement redundant.
"No… it can't be…" Eevee muttered as the entire Temple of Time began to rumble dangerously. She gasped and screamed as a bright pink crystal prison suddenly materialized all around her, trapping her inside.
"Hey, that thing looks like a Rupee! I want it!" said Pikachu, running up to the crystal and gnawing on it.
"Well well, Princess… I commend you for avoiding my pursuit for seven long years," came Mewtwo's voice. "But you let your guard down… plus you put your trust in this dumb kid, which is the most fatal mistake that could possibly be made! Now the power of the Triforce of Wisdom will be mine!"
It was at that very moment that Togetic decided to snap out of it. "OH NO YOU DON'T!" she shouted, jerking her head up. "YOU CAN'T KILL HER BECAUSE I'M GOING TO KILL HER!"
She flew at the crystal and started pounding on it while shrieking maniacally, but it didn't do a thing. Suddenly the crystal began floating up into the air, taking the terrified Eevee with it and leaving Pikachu and Togetic to watch helplessly.
"If you want to rescue Eevee, come to my castle!" said Mewtwo, and Eevee and the crystal vanished into thin air as he let out a wicked laugh.
––
Knowing he had no other choice, Pikachu raced out of the Temple of Time and over to Mewtwo's Castle as fast as he could. It was situated in the same place Hyrule Castle used to be, but this one was huge and dark with a towering spire in the middle, and it was sitting on a land mass that was floating above a lake of lava. This was never given any explanation.
"Okay T-money, this is it! We gotta rescue Eevee and defeat Mewtwo once and for all! Now let's storm that castle and bust some heads!"
"I'd love to, Pikachu, but we can't get in the castle. There's no way to cross over that lake of lava."
"Really? Okay, I give up. Let's go home."
"Pikachu… can you hear me? It's Jolteon, the Sage!" echoed a familiar voice in the air. "The six of us will combine our power to form a bridge over to the castle. Once you're inside, though, it's up to you to destroy the six evil barriers blocking the way to the castle keep."
Togetic frowned. "Seriously? If you guys can create matter out of thin air, why are you making Pikachu do all the work?"
"For the narrative drama, mostly," Jolteon replied as a bunch of multicolored sparkles suddenly began floating down from the air. Pikachu jumped back in surprise as they coalesced to form a huge bridge spanning the gap across the lava bed, leading directly into Mewtwo's Castle.
Pikachu didn't look pleased. "Excuse me, but why is this bridge all sparkly and rainbow-colored? I demand a MANLY bridge!"
"Shut the hell up, Pikachu. Now get in there or we'll drop a second bridge on top of you."
"Okay, good incentive," Pikachu decided, quickly charging across the bridge. "C'mon Togetic, let's go rescue Eevee!"
"Yes, I agree! We have to save her so I can painfully kill and eviscerate her later! Nobody plays with my heart like that!"
"T-money, I'm pretty sure she wasn't playing with your heart all. In fact, she was pushing you away the whole time, and now we know why."
"That's enough out of you, fatty!" Togetic snapped, kicking him off the bridge.

A/N: Sorry to everybody who was expecting Eevee to be a Glaceon. I thought it wouldn't make much sense for her to evolve into an Ice-type when Zelda's supposed to be the Sage of Time. :/
