Blake: wow this cafe is really nice.

You: well I know a guy who got me a secret drink he's really fast with texting.

Blake: well you ready to give this a shot.

I then went to a rooftop and said an embarrassing thing to my friend Barry.

You: love you.

Barry: wow Y/n never knew you felt that way.

You: Barry! Wait you're Oliver Queen. And you two no idea?

???: I am Arthur this is Dianna where are we?

Oliver: looks like vale.

You: wait you're batman. The batman.

Batman: yes Y/n it appears we haven't formed the justice league.

Barry: no we have he isn't apart of it now where's our Batman?

Batman: great my doppelgänger must have went to this earth by mistake we need to find him before super man and his army shows up.

You: wait doppelgänger is this another earth? And why we running from super man?

Batman: trust me flash we need to find him.

You: Barry your the flash and I can't my ring is nearly out of power did this world me get fired.

Batman: no.

You: good I have to go send me your location.

I arrived at Ironwood Air Force to find the battery then I heard an electric sound and went to find it.

You: hey!

Cyborg: you're green again.

Raven: no this isn't our Y/n L/n.

You: you're cyborg and Raven part of the teen titans.

Cyborg: was.

You: I don't know what's going on but I have to stop you.

They both tried to attack me but I had enough juice to knock them out with a shockwave but it used up my power and went to an ice cream girl.

You: you ok?

She had a shocked face then tried to kick me.

You: hey wait I'm on your side.

She started do hand sighing.

You: sorry I can't understand I'm a green lantern maybe if I can find a power battery I can. And she's gone.

Barry: Y/n help two guys dressed as you one is called Sinestro and the other.

You: hang on I'm coming.

I arrived to see Wonder Woman and I figured who everyone was then I was hit by Sinestro.

Sinestro: so a L/n we meet.

You: I heard you took over your planet now you're working with Superman.

Sinestro: an alliance was necessary now come at me!

We clashed our rings and fought but I gained the upper hand and knocked him out I went to help Wonder Woman.

Wonder Woman: Y/n.

Y/n: someone call my name?

You: Yello lantern did the ring corrupt you.

Y/n: no after loosing them and the guardians didn't care I followed Sinestro.

You: who's them.

Y/n: you will find out.

You: fine then time to kick my ass.
