Ash gives her a funny look then bursted out laughing

Serena: Whats so funny?!

Ash: LOOK AT YOUR BUTT!

Ash keeps laughing

Thinking ash is a pervert, she reluctanly looks at her butt...

Serena gasps

Serena: WHAT IS HECK IS THAT?!

Suddenly she finds her and her clothes shrinking
(She keeps her hair)

Serena: Well, at least my clothes shrunk with me...

Ash: Serena, your mew DNA is getting in your system, and its mixing with your human DNA so you are now turning in to a mew

Serena: so im at least still human?

Ash: well, im actually part human too!

Serena: then why did you need to turn me into a pokemon

Ash: well, i felt like if i didnt, people might still judge us...

Serena: oh...

Ash: plus then we can team up against bad guys like team rocket!

Serena: oh okay!

Ash: also 2 more reasons... 1 then we are both the exact same 2 species! Also, of your not part pokemon you have to have permission every single time you enter The Hall of Origin...

Serena: oh okay!

Ash: WAIT! I am forgetting the most important reason! If i dont, i will just outlive you! But now we are both imortal!

Serena gasps

Serena: were i..imortal?!

Ash: yup!
Ash gives her a toothy grin

Ash: and excuse me for a second, i need to make a video call

On the video call

Ash: Hey Gary! We have an emergency!

Gary: IS TEAM ROCKET TRYING TO TAKE OVER THE WORLD?!

Ash: No! All our friends except Paul, Zoey, Kenny, Sawyer, Clemont, Bonnie, Max, Barry, and Serena have turned on us!

Gary gasps

Gary: EVEN BROCK?!

Ash: yes, even Mr. Super Ultra Pervert!

Gary burts out laughing

Ash: they tried to kill me though!

Gary gasps

Gary: WHY?!

Ash: They said im so weak that im a discrase to all trainers and that i had to die because my existance threatned the lives of all legendaries! But its irronic that thats the main reason!

Gary: and why is that?!

Ash goes into his arceumew form

Gary's jaw drops

Gary: a..ashyboy.... what a..are you?!

Ash: im actually the son of acreus and mew, which i found out right after the insident

Gary: how long ago was it?!

Ash: 1 year ago, for the past year i was training with my dad and the other legendaries so i can help protect the earth from 'it'

Gary: WHATS 'IT'?!

Ash: every evil team known to man is going to team up and try to control the world!

Gary gasps

Serena: hey gary! Guess what?!

Serena changes into her mew form and garys jaw drops

Gary: h..how?!

Ash: i made her half mew so we can date!

Gary: Man! I wanna be part mew!

Arceus telepathocly sends ash a message-
Any recruits are aloud to become part mew if you let them...

Ash: *telepathicly* Thanks Dad! =D

Ash turns Gary into a mew

Ash; hey gary!

Gary: yeah?

Ash: theres something on your butt!

Gary sees a pink tail then shrinks along with the clothes hes wearing
(He keeps his hair)

Ash goes into his regular mew form as well (he also keeps his hair)

Ash: now we are all mews!

Gary: you actually let me?!

Ash: my dad said all recruits to help save the world were aloud to become 1/2 mew

Gary: COOL!

Ash: okay guys! You ready to get back at those traitors?!

All: yeah!

Suddenly Dawn burts in and they all instantly change into their human forms

Dawn: GUYS I NEED TO APPOLOGISE BIG TIME! THEY WERE FORCING ME TO DO IT! THEY SAID IF I DIDNT THEN THEY WOULD KILL MY POKEMON!

Ash: oh... well we forgive you!

Ash turns her into a mew

Dawn feels herself and her clothes shrink and she becomes a mew (Keeps hair)

Ash and Serena both go into theyre mew forms

Ash: Now all of us are mews!

Dawn: WAIT WHAT?!

Dawn: well are you two ready to get back at those traitors?!
