Another Doctor Who/LOK fanfic here you go u r WELCOME.
At first he’s just laughing, the same laugh as his brother. And as they laugh together, doubled over with their hands on their knees, all Mako can think is that they’re safe. Safe from Amon, safe from his evil minions, the Equalists; they’re all safe from it all, back in the TARDIS. Bolin clasps a beefy, sweaty hand on his shoulder and exclaims, “You did it, bro! Man, you should have seen it! You were glowing—and I don’t mean “glowing” because we both know you’re never that charming—but I mean really glowing. Like—blue! The blue Korra glows! The blue the TARDIS glows!”
So the laughter dies down and Mako gathers his bearings, thinking. “Glowing? Blue?”
“Don’t remember, do you?” Her voice is tight, quiet and Bolin and Mako stare at her as she stands in front of the TARDIS control panel. She grunts, squeezing her eyes shut a few times, balling her fingers in fists. “Not surprised. The Avatar State isn’t something meant for mortals.”
Mako frowns. “I was in the…Avatar State? How?”
Korra bangs the TARDIS. “I keep this thing alive, and in turn, it keeps me alive. It’s heart contains all my lives, past and future.” He’s suddenly aware of her labored breath, the sweat collecting at her brow. “Tell me—do you really not remember?” she asks softly.
Mako closes his eyes, trying to think. He sees faces—so many faces—and almost gets overwhelmed. So he pushes them away, compresses the memories to dusts and answers, “No,” because he simply can’t handle remembering—he isn’t her.
“Right,” she drawls, but she’s grinning all the same.
“Alright then!” Bolin rubs his hands together hungrily. “Where to next? The Planet of Ba Sing Se?” he dances around spookily. “The Spirit Realm?”
Korra chuckles, a pained look on her face as she stares at her palm—she watches as bold blue beams like a light, pulsing through her veins. “I was so looking forward to taking you guys there. Oh, the places we never got to see! Especially my favorite planet—a tundra really. But a world of white. I’ve never seen anything more beautiful. The penguin sledding is also a bonus.”
Bolin frowns. “Why can’t we go?”
She huffs, “Maybe we will—but not like this.” She points to herself and a pathetic excuse of a laugh comes trickling out. “Not as Korra, Mako and Bolin. No. Not like this.”
Mako becomes aware of the glow in her hands. “What’s wrong?” He asks hurriedly.
“I—“ She lurches back, her eyes disappearing behind a blue tinted glow, so fierce, so bright, the boys have to shield their eyes until it fades, seconds later-like a firework, she popped and fizzled, but the light was soon gone. They take a few steps forward before she screeches. “No! Don’t come any closer!”
“Avatar Korra? What’s going on?” Mako hears the frightened child in Bolin’s tone.
She grunts. “Mako absorbed the glow from the TARDIS—the power that gives me the Avatar State, and so much more. But I had to absorb it to save him—more than I can handle, more than any other Avatar could handle—“ she pauses. “It’s too much. My cells are dying, bursting. Every one of them.”
Mako spends all his time with her—so much time, his concept of time has been strewn. All he knows is that she’s taught him that time is constantly moving—everything is spinning and turning and when he’s with her he believes her, because he can feel it too. Standing next to Korra he can feel the Earth spin thousands of miles per hour under his feet.
But at this moment he swears time stops.
“Can’t you do something?” Mako asks, breathless. His hands ghost toward her pained figure, but he keeps his distance like she asks.
“Yeah, of course—I don’t die, not really. I told you I’ve lived thousands of lives and I’ll live thousands more. Time to move on to the next one. Go easy on me, will you?”
It gets quiet as her friends, her companions, just stare. “I don’t understand.”
“I’m going to change,” Korra says blunt, harsh, and it’s like a knife to both boys’ hearts. “I could have green eyes or brown. I could have fiery red hair or no hair at all! I could be mean…well, meaner. I could be a total wimp. But I’m going to change. I’m not going to see you again—not as Korra. Not ever again. So, before I go—“
Mako steps forward tears welling in his eyes. “Korra, please, don’t—“
“Mako, Bolin—it’s going to be okay. Just…deal with it, alright? You got to deal with it. And you’ll be just fine. I know it.”
And like a star bursting, expanding…like a firework bursting in the navy sky her eyes ignited, then her arms, her legs, her—everything. She is engulfed with the prettiest shade of blue and that’s when he decides—
—that is the color her eyes had been all along.
The light fades and Korra leaves—but the blue, the blue remains.
In a bright arrow atop her—his—head.
His head is shiny, bald. He’s about the same age, fairly close Mako decides. The Avatar before him has grey eyes, stands taller but a smile just as wide as hers.
“Ah, hello—oh.” The Avatr stops, bewildered. “That’s a man’s voice. Alright then. Mako. Bolin. Where were we? Oh yeah! Will you go penguin sledding with me?”
Bolin leans into his brother and whispers, “She never said she could end up a dude…”
But as Mako stares at the new Avatar before him, decked out in blue tattoos and childish wonder, Mako can’t help but laugh.
“Let’s go penguin sledding then.”
AN: I decided that if I’m going to go fuck around with this crossover I might as well fuck around with the Avatar cycle so yep Korra regenerates into AANG WOULDN’T THAT BE WEIRD.
