I'll do one :D

*As long as you don't mind me also using some variants of my Miitopia chars, and slow replies cause of ma book review.

We open on a peaceful scene.A lone blue reploid can be seen walking in a forest,listening to the sounds of wildlife.

X:(breathes deeply)Ahh...Another great day!^^The only thing missing is someone to share it with...

*nearby, there are two others, a black and red female reploid with spiky hair similar to Axl's, and a human wearing a white-blue-green cloak and having an odd staff - the two are having a picnic as the female Reploid is often too friendly for her own good*

Sora (the female reploid, she is Axl's sister if you're ok with that): So your name's Koko, huh? And you came from another world?

Koko: *is eating a sandwitch*

(nearby,X sees another reploid,a red cat-like hunter)
Alpha:zzz...
X:Hey Alph!
Alpha:(wakes up)Gah!(falls)Oww...
X:You alright Alph?(comes to Alpha,helps her up)
Alpha:I'm fine.Good thing I had a more rugged lifestyle growing up!^^My older brother on the other hand,Zero's had a bit more...luxurious childhood.
X:Agreed.(looks around and sees Sora and Koko)Hey!There's Axl's sister over there!
Alpha:I didn't know Axl had a sister...

Sora: *spots the others and eagerly waves* Hey guys!! :D *she's a very hyper sort of gal*

Koko: ? *looks at them curiously*

X:Hey Sora!^^Axl causin' mischief as always?
Alpha:Afternoon!
