Voltron Sidekick?

Sidekick

"Uh, Coran? Are you sure this is the right place?"

"The distress signal came from this planet, I'm sure of it."

The paladins scout the mossy, vine and grass-covered area, searching for anything that's still living. "Careful guys, this air is highly toxic-"

Lance cuts off Shiro, "Highly toxic?! You could've mentioned that earlier! Why are we still here??"

"Relax Lance, this atmosphere doesn't have a strong effect on us, so we should be fine for about an hour." Pidge assures.

As the paladins spread out across the area, Keith finds a hidden shack underneath a bunch of vines. "Hey, I think I found something." He cuts vine branches out of the way and creeps into the building.

Everything in there is mostly covered in mold or torn apart. Despite the moss growing inside, the broken windows, and the awful smell, it could be a pretty nice house. Keith explores more of the shack, entering a small room, seeming to be a bedroom. He hears the slight sound of breathing coming from inside a closet. He carefully steps closer to the closet.

Keith opens the doors, revealing a boy inside with a knife. He tackles Keith to the ground and holds a knife up to his throat, "What do you want with me?! Who are y-" His bright e/c eyes widen, "Y-You're...not Galra?"

"...No, I'm not." Keith assures, but the boy presses.

"Yeah right, I bet they're tracking you right now. What more do you want from this place?!"

Keith grabs his wrist-the hand holding the knife-softly, "Nobody's tracking me. I'm one of the paladins of Voltron here because of a distress signal." He says carefully. The boy lowers his knife and leans away from Keith.

"I didn't think it'd actually work." He says to himself while staring down at his knife in his lap.

"What would work." Keith sits up, propping himself on his elbows.

He looks at him, then sighs, "After the Galra attacked our land, I was forced to scour around and find anything that'd help me survive. I found a ship, or something, and started it up. It can't fly, but there was this big button saying that it'd send help. I thought the thing was busted, but I tried it anyway."

"Are you the only one left here?"

"Yeah..." He fights back tears. "Can you paladins fix a ship?"

"Uh yeah, but I think you should stay with us."

"Why?" The boy snaps, "I can defend myself. I can fight! I would've cut you if you weren't a defender of the universe."

"That's why. You're emotionally unstable."

"What?! I outta cut your tongue off!" He threatens as his knife returns toward Keith.

In a flash, Keith slips out from underneath the boy, knocks the knife out of his hand, and pins him to the ground. "Now, are we gonna have any more trouble, or do you want to team up with Voltron?"

The boy struggles underneath him, "No! Get off me!"

Keith shrugs, "Fine by me."

~Time Skip~

"Where's Keith? He should be back by now." Lance looks around impatiently.

"Right here." Everyone turns around to see Keith with the boy tied up on his shoulder.

Hunk speaks up, "Okay Keith, what are you doing?"

"Yeah, what is that?" Shiro questions.

"The source of the signal. C'mon, let's take em in the castle."

~In the castle~

"Keith! You can't just tie up a stranger and bring him on board!" Shiro yells at Keith.

Him?! The boy wonders.

"Why not? He's the last person on this planet, plus he can fight. I think he can help us." Keith explains.

Pidge kneels in front of the tied up boy, who was put on the ground, and eyes him. "Guys, I think he's human." 

"What makes you say that?" Lance says.

"Well for one, he has a regular skin tone. And he has an average body temperature. Can you speak English?" Pidge pulls the tape off his mouth.

"Yes, I am human." He says.

"What's your name?" Shiro asks.

"Y/N L/N" He answers.

"What's a human like you doing out in space on a different planet?" Lance questions.

Y/N chuckles, "I can ask the same thing." 

Allura steps forward, "Y/N does not seem like a threat. Perhaps...he could join our team."

"Wait, hang on a second...is there free food?" Y/N asks hopefully.

"Yes."

"I'm in."

"Fantastic." Coran cheers, "A new member to the team. You can help me around the castle, like cleaning, fixing t-"

"Around the castle? But if I'm gonna be kidnapped by Voltron, the least you could let me do is fight with Voltron!" Y/N argues.

"No can do. We don't know what you can do yet, so for now, leave the hero work to the paladins." Y/N slumps.

"So it's settled." Shiro walks over to Y/N and starts untying him. 

"Hang on a second," Keith says, "When I asked you if you were the last one at the planet, you said yes. If you're human, who else were there?"

"My family, of course. We left Earth together and settled on that planet. There were only small creatures living on our planet back then, so the Galra took advantage of our land." Y/N takes a deep breathe, "They killed my family for fighting back."

"Oh...I'm sorry." Pidge says solemnly.

"Forget about it. My family was just dead weight anyway." Y/N says harshly leaving everyone in silence. Y/N awkwardly continues, "So uh...what's for dinner?"
