This is an interesting AU, I was playing around with the Hetalia wiki and found an article on one of my favorite segments: Neko!Talia. That's right, cats. I started laughing as I was wondering what would happen if there were cat versions of FMA characters roaming around. So I had my Fem!Ed get a cat version of herself and thought she would be lonely. Then I remembered, it was either Aztec or Mayan, but they predicted that this century will end with a rain of cats that use fire. That probably means something entirely different but it made me evil grin… a cat Roy Mustang would do the trick.
So, ready for the saga of Ed Cat and Roy Cat? Too bad, you're about to get it anyways.
The office of Roy Mustang had been rather quiet since Edwarda Elric quit. Maes Hughes dropped by whenever possible to fill the noisy gap. Not even Roy minded the noise his best friend made. One such time, Maes looked up as Edwarda walked in. "Hey, Ed!"
"Hello everybody but Mustang!" She cheered.
They all gave Roy's office door a look but it remained shut. He hadn't heard or he ignored her. "How are you doing, Ed?" Riza Hawkeye asked.
"Fine, but the strangest thing happened last week. I was thinking about cats and then my side was paining me. I looked down and there was a cat on the floor, a golden eyed calico."
"Ed Cat?" Maes asked.
"Yeah. I went shopping for stuff to take care of her and would up with double of everything so I put it aside just in case. I won't need cat food for a while." She blinked. "That reminds me, I got a book in about predictions of how the world will end and you know what one legend is?"
"Falman probably does," Heymans Breda remarked.
"Which one?" Vato Falman asked. "There's so many."
"I'm talking about the giant flaming kittehs of doom one."
"So, in other words," said Maes, "Roy Cat."
"Something like that," Ed admitted.
"What the hell?" Roy was heard shouting through the closed door. "A cat just came out of nowhere!"
Maes and Ed walked into his office as he came out, rubbing his scarred side. "It's an omen," said Maes.
Roy looked at him in confusion. They walked out again, Ed carrying a large domestic black cat. "It can't be," she said. "This guy's too small and there's only one of him."
"So Roy Cat isn't a sign of the end times?"
Both the cat and Roy blinked with the same black eyes. "We better keep an eye on him just in case he starts displaying the same abilities as his human counterpart, because if he does, it just may be so," Ed said thoughtfully.
"What the hell are you talking about?" Roy asked. "This cat is me and the end of the world?"
"I don't know about the end of the world part," Ed replied, "but yes, this is the cat version of you. What are you going to do with him?" A large black paw slapped her across the face. "No, bad Mustang Cat."
"I don't like cats, but even if I did, I still couldn't keep him," Roy told her. "My landlord doesn't allow pets."
"Fine then," said Ed. She got slapped again. "Stop that."
She lifted the displeased cat out of slapping range. "Meow!"
"You're a cat alright and I have a soft spot for cats. I'll take you in." She repositioned him. "Even if you are Mustang Cat."
"What was that supposed to mean?" Roy asked.
"You called me a bite-sized brownie last week."
"That was payback, half-pint?"
"I'm just going to leave now and pretend Colonel Mustard isn't out here. Bye, everybody else!" She left, the cat looking over her shoulder at them.
