Frankenstein's Pocket Monster (Zombie Gallade)

Story
A conversation took place one day.

-"Huh? what is that smell? where is that-HOLY SWEET ARCEUS!"

-"Oh...hi there! Nice to meet 'ya!"

-"Uh...I...think there's something wrong with your pokemon-"

-"Oh, my Gallade? What do you mean? He looks fine!"

-"He looks...and smells...like he just came from a dumpster fire-"

-"Yeah, he had a bit of a mishap. But it nothing I can't fix! *laughs*

-"Did he...die!?"

-"Well...haha...maybe a little...but thankfully, I was able to heal him up pretty easily!"

-"Is that rotting skin!? I think I'm gonna vomit..."

-"Is something wrong?"

-"I'll tell you what's wrong! You! You can't just bring dead pokemon back to life like this! Look at him!"

-"What do you mean? All I had to do was fix him up a little bit, and now we can have adventures forever and ever!"

-"You're a psychopath! I'm calling the police!"

-"Well, sorry to hear that! *more laughter*"

-"What are you talking about!?"

-"Gallade, you know what to do!"

-"Huh? What does that...wait, w-what are you-*screaming*"

-"Good job, Gallade! Now, let's get out of here before anybody sees the body. We have more fun adventures to go on! *laughing*"

Later, a body was found on route 13. It seemed that his body was mangled and cut open in an extremely gruesome way. Clearly, no human would've been able to do this.

Summary
There was once a pokemon trainer with a Gallade. This was his favorite pokemon and they had so much fun together. But then, one day, his gallade died. He couldn't just accept that his favorite pokemon died, so he went to the pokemon center. When they couldn't do anything, he decided to take matters into his own hands. He went into a lab and spent YEARS trying to bring back his beloved pokemon. He finally managed to bring Gallade back to life, but he was a mindless zombie that does nothing but listen to his orders. However, during this time, the trainer had been driven to insanity, so he didn't care what gallade looked like anymore. He's just glad his friend's back.
