Author's Note: This is for Gamelover41592, for requesting a PnF and KH for reviewing on my sister's story Finding a way back to our Dimension. Unfortunately, she doesn't have time to create it, however, I told that I'll take care of it and here it is. Enjoy and don't forget to Review.

Summary: Terra has helped Doofenshmirtz created a Death Ray-Inator, and he defeated all the unversed Vanitas who came out of nowhere with a little help from Doofenshmirtz. Then, Ventus and Aqua came over. Aqua helped Perry defeat Dr. D. Meanwhile, the Vanitas came to the Flynn-Fletchers household and Ventus, Mickey, Phineas and Ferb teamed up to defeat them.


Chapter 1 - Terra and Doof built a Death Ray

Disclaimer: I don't own anything.


While Terra was travelling to the galaxies, He saw Vanitas goes to the World of Phineas and Ferb. Terra followed him, and landed at Doofenshmirtz Evil Incorporated.

Terra: Where am I?


Later...

Terra: Excuse me, have you seen a boy with a black suit and a helmet?

Doof: No. Ooh, why not help me build a Death Ray-Inator! *evil laugh* and I'll help you find your kid deal?

Terra: Okay.


After building the Machine or the what-you-called "Inator".

Doof: Ooh, Let's test this baby.

The unversed popped out of nowhere

Doof: Aaah! what are those?!

Terra unleashed his keyblade.

Terra: The unversed, stay behind me!

(A/N: Don't kill me. I skipped the battle scene.)


Doof: Whew! Thank you.

Vanitas: Terra, what a pleasant surprise.

Terra unleashed his keyblade

Terra: You!

Vanitos unleashed his keyblade.

Doof: So, He's the one you're looking for right?

Terra: Yep, and his very dangerous, so stay out-of-the-way.

Doof tries to hit Vanitas with his Death Ray-Inator, but Vanitas blocked it. Terra used Mega Flare and Vanitas got hurt. Vanitas is aiming at Terra, but Terra used Dark Firaga, but then again, Vanitas shot-lock. Terra got hit and hurt. Doof uses his Death Ray-Inator again, and Vanitas got hit. Terra used Ars-Solum and of course, Vanitas got hit and hurt again. Vanitas counters with Thundaga, Terra blocked it, but our beloved Dr. Doofenshmirtz got hit. Terra used Blizzaga, but he missed and used Aerial Slam and Vanitas got hit. Vanitas attacked Terra, and Terra got injured and he used Curaga. Doof wakes up and hit Vanitas again with his Death ray-Inator, and Vanitas became unconscious.


Terra: Are you okay?

Doof: Yeah I'm fine. You?

Terra: Yeah.

Doof: And, He's gone.

Terra: Don't worry, He won't come back.

Doof: Thanks anyway. I mean you kinda saved my life twice.

Terra: Don't mention it. I gotta go.

Doof: Okay.

With that, Terra left.
