Omake: Flight Test
[Camera P.O.V.]
The camera screen flickers on, focusing in on the hanger of the Plumber Base. The camera lens peers around taking in the stakes of large crates and alien devices strewn about the hanger, up above lies a catwalk leading to the higher levels of the Plumber Base.
^Are you sure about this?^ The camera peers over to Glad-One who is perched atop a nearby crate.
He's holding the nozzle of a large fire extinguisher that sits just beside his body.
"No, but I need the practice." Izuku Midoriya holds up his deactivated hoverboard, shaking his head, he has yet to notice the camera trailing on him. He's currently wearing his one of a kind hoodie, its black and green hues matching his Omnitrix. "I rather not have to learn to use this thing while on the job."
^And why not? You're very good at learning on your feet.^
"Thanks, but I figured this is for the best."
^Yeah, wouldn't want to hurt, humiliate, or maim yourself in front of a villain.^ chimes in Sad-One, the camera shakes as he speaks.
Izuku throws Sad-One an insulted glare before his eyes widen at the sight of the camera he's holding. "What's…with the camera?"
Glad-One goes ahead and explains. ^Oh, it's for the documentary series!^
Izuku raises an eyebrow. "Documentary what?"
^It's when we make fun videos for our lovely audience!^
Izuku shouts out in worry. "Audience?!"
^Well, if we had an audience that is.^
Izuku visibility relaxes. "Oh, so no one's going to see this?"
^Most definitely not. Not like they'd like to.^
Izuku frowns dejectedly before shaking head. "Alright, I guess it's not an issue." He begins to back away from the camera while gripping his hoverboard. "Let's do this, right." Izuku looks over toward Glad-One. "You're on fire safety, right?"
Glad-One nods his little body. ^Of course! And you can say I'm fired up for this test!^
Izuku chuckles. "Ha, good one."
The camera screen shakes. ^No it wasn't.^ comments Sad-One.
Izuku goes ahead and moves on. "Well if everyone's ready, then I should get set too."
Izuku tosses the hoverboard down and it immediately activates, enlarging itself and becoming a hovering platform. It hums as it remains motionless in the air awaiting its rider.
"Alright, step 1: get on the board." With a nervous breath Izuku jumps onto the alien device. "Woah. Woah!" His arms flail about as the hoverboard wobbles underneath his feet, threatening to launch out from under him.
^Steady Mr. Deku. Steady.^
"I'm trying!"
^Clearly not trying enough.^
"Not helping!"
^I'm not trying to help.^
After a moment of wobbling and shaking Izuku gradually gains control, becoming steady. "Phew, that's it. I think I'm getting it."
^Yay! I knew you could do it!^
^At least one of us did.^
"Alright, that was step 1 but now for the real thing." Izuku takes a nervous breath. "Flying."
Before he can even attempt it, Glad-One begins to cheer and ooh! ^Ooh, ooh! Can you say it?^
"Say what?"
^You know, say Flight Test Number 1. For the camera, for our documentary.^
"Um, okay I guess." Izuku goes ahead and goes along with it, looking directly at the camera while still trying to maintain his balance. "Um, this is Hoverboard Flight Test Number 1."
^Thank you!^
^You're too easily excited.^
The two counter-parts that make up One-One soon settle down as Izuku prepares himself for flight.
With his arms still outstretched, maintaining his balance, Izuku peers over at Glad-One. "You ready with the fire extinguisher?"
^Yes!^ Glad-One shakes around the nozzle of the fire extinguisher to emphasize his point.
"Camera?"
^Yeah…^
Izuku nods, taking another slow breath as he gently eases himself.
"Gonna start off nice and easy. No need to rush it."
The entire hanger is silent, only the hum of the hoverboard makes any noise as they all wait with bated breath for Izuku to start.
When he finally feels good and ready Izuku looks to Glad-One and gives him a nod, confirming he's ready.
Glad-One nods back, his fire extinguisher at the ready.
And so Izuku begins, leaning ever so slightly forward to get the hoverboard to move. "Moving on 3…2…1."
He leans and immediately the hoverboard rockets backwards and smashes Izuku in a pile of crates!
"Gahh!"
With no hesitation, Glad-One fires off the fire extinguisher dowsing the cadet in foam.
Flight Test Number 2
A foam covered Izuku stands before the camera. "Okay, Flight Test Number 1 was a bust but I'm sure Flight Test Number 2 will be way better."
He backs away from Sad-One and the camera, towards the already in place hoverboard.
Izuku goes ahead and jumps onto the device, it wobbles underneath him, threatening to throw him off, but he manages to regain his balance.
When he feels ready, Izuku signals that he's about to begin with a nod. He leans and… The hoverboard fires forward right from under him, throwing him off!
"Wah!" Izuku slams onto the ground, groaning in pain.
Glad-One peers down at the young cadet. ^Oh, boy. That looks like it hurt.^
Sad-One nods in agreement. ^I bet he broke something.^
Flight Test Number 5
"Wah! Woah! Woah! Wahh!" Izuku is desperately trying to keep his balance as the hoverboard shakes and wobbles under his feet.
And then the hoverboard zips up and over, flipping Izuku backwards and throwing him onto the ground.
Izuku groans and hisses, knowing full well that a bruise will be there for sure.
Glad-One gasps in worry. ^Are…are you okay?^
Izuku responds with a pained groan.
^He's fine.^ replies Sad-One.
Flight Test Number 9
"Woooooaaaaahhhhh!" The dizzy and nauseous greenette is being spun around like a top as the hoverboard spins and spins continuously under him!
Flight Test Number 14
A banged up and bruised Izuku is just standing there, staring down at the hovering hoverboard, blinking at it like it'll just come to life and give him the answers.
Glad-One gives Izuku a questioning and somewhat concerned look. ^Aren't you going to get on?^
Izuku nervously looks away. "Um…maybe later." He quickly retreats, deciding now was a good time for a break.
As he marches off Glad-One looks to camera unsure of what to do next.
Flight Test Number 20
"Ahhhhhh!" Izuku is gripping onto the hoverboard for dear life as it rockets uncontrollably about the large hanger. "Get me off this thing!"
Glad-One chases Izuku from below, the fire extinguisher bouncing along behind him as he drags it along. ^That looks like fun! I want a turn!^
Flight Test Number 37
Izuku takes a breath and steps away from the camera, gripping the inactivated hoverboard. He is armored up wearing a helmet, knee and elbow pads, and even chest pads. But most importantly there is an air of determination emanating from him, even though he's all decked out in padding he just has a feeling about this go.
"Flight Test Number 37." Izuku tosses down the hoverboard that immediately expands and activates. "As you can see, I am properly geared up for this one. And for lack of a better option, One-One is still on fire safety."
Izuku quickly addresses said robot. "By the way, please don't dowse me again, I'm pretty sure that stuff doesn't wash out."
^Oops, sorry.^ Glad-One aims the fire extinguisher away from Izuku. ^I guess I've got a bit of an itchy trigger finger.^ He stares down at his stubbly little appendages. ^Which is weird because I don't have fingers.^
Izuku shakes his head in amusement before turning his attention to the matter at hand. "Alright, nice and easy." He cautiously mounts his hoverboard, which wobbles but he quickly manages it. "I'm just going to start with a slow start." He braces himself, bending his knees, and taking a few breaths. "3, 2, 1."
With a gentle lean forward Izuku begins to move, slowly inching his way forward. He leans more to the side, turning his trajectory and soon he's moving in a slow circle. As he moves around, he notices Glad-One aiming the fire extinguisher after him. "Please don't aim that thing at me-Wah!" He temporarily loses his balance before regaining it. "It makes me feel like I'm going to catch on fire, spontaneously."
Glad-One quickly aims the fire extinguisher away. ^Oh, my we wouldn't want that, now would we?^
^I don't know I think that'd be something worth seeing...^ adds in Sad-One. ^But I guess it wouldn't exactly be a blaze of glory, now would it?^
Izuku ignores the two and focuses back in on the camera. "Alright, now I am going to try to move a little bit faster."
And so with fire in his heart, the will of determination pushing him forward, Izuku slowly moves forward. He then slowly rises higher and higher into the air and as he gains confidence, he begins to move just a tad faster.
Sad-One has to prop the camera up while keeping the lens trained on Izuku as he gradually flies about the hanger.
Soon with enough confidence Izuku is flying faster and faster around the hanger. He nearly slams into the catwalk and piles of crates a few times but thankfully he never goes tumbling off the alien device. Eventually he's moving through the air performing skateboard like tricks.
"Wooo!"
Glad-One claps! ^Well done, Mr. Deku!^
Sad-One mopes. ^I bet he crashes.^
"Hahaha!" Izuku swoops down and over the bots, whipping wind at them as he races past.
He swerves and circles around before gliding down to his start point, coming to a full stop before looking to the camera.
"Yeah, I can fly."
