This story came into my mind and wanted to type it.
Disclaimer: I don't own Pokemon and Dragon Ball Z
It was a dark day for the world of the Pokemon shapeshifters. One of them, female, stood on a cliff as an Arcanine watching the destruction of her planet.
"Mom!" a small, shiny Growlithe growled as she ran up to her mom. "Frieza just arrived on the planet!"
"Well done Hawk," the Arcanine said. "Where at?"
"Over by where the Shadow-Shifters used to live," Hawk said.
"Hmmmm," the Arcanine hummed. "You can't stay here."
"Why not?" Hawk barked eagerly. "I can fight!"
"I know," Hawk's mom said, "but you have a bigger role to play right now my loving daughter."
Picking up Hawk in her mouth, the Arcanine ran with all her might to an escape pod.
"Mom! Please!" Hawk begged. "I want to stay and fight along side you!"
"Hush now!" the Arcanine said, putting the Arcanine in the escape pod, where two humans were sleeping. "What I want you to promise me right now is to protect these two, no matter the cost!"
"But-"
"Promise me!"
"I promise, mom."
"You three should be well on Earth by the time the two wake up."
"Ok mom. What's with the bag though?"
"Evolution stones."
With that said, the Arcanine closed the escape pod and Hawk stared at her mother sadly before pushing a button to escape from her doomed planet. The Arcanine, pleased that her daughter escaped with the two humans, turned and ran to where Frieza was, knowing that the battle would be epic and one will come out victorious. The Arcanine narrowed her eyes as she ran faster and faster to determine her future.
"FRIEZA!" the Arcanine barked out when she saw the purple monster. "I am Rogue! Defender of this planet!"
"Oh! I'm so scared!" Frieza mocked as he grinned. "Or are you foolish enough to challenge me?"
"I fear no one Frieza," Rogue snarled. "I am the last of a rare bloodline! After me, there is no one else!"
"Rare...bloodline?" Frieza asked, rather bored. "Let's just get this over with."
"I agree!" Rogue said, transforming into a Rayquaza.
"Oh dear, what ever shall I do?" Frieza asked, in mock horror. Rogue, smiling used Thunder on him, but missed as Frieza dodged it swiftly. Getting close to Rogue, Frieza used his Death Beam in hopes of hitting her first, but that wasn't the case as Rogue turned into a Mew and dodged it fast. Turning into Arceus, Rogue used Judgement and hit Frieza head on.
"Got him!" Rogue said.
"But not good enough!" Frieza said using another Death Beam and hitting Rogue this time. Rogue stumbled back and used Giga Impact, hitting Frieza head on again. Standing as a target, Rogue begged for her strength to come back.
"Come on," Rogue growled.
"What's the matter?" Frieza mocked. "Can't move?" Frieza raised a finger and fired a Death Beam at Rogue. Rogue smiled and used Double team to dodged it.
"Almost had me!" Rogue said, laughing. Frieza, not used to being laughed at alot, growled.
"Why you little..." Frieza snarled. Moving at a speed Rogue can not match, got pounded time and time by Frieza until Frieza knocked her to the ground. "Had enough?"
"Not yet," Rogue gasped, turning into Dialga. Frieza smirked and rushed Rogue, only to find himself moving a tad bit slower than Rogue. "One of my last playing cards. ROAR OF TIME!" Rogue, trying to save her planet, unleashed a horroryfing roar that breaks time apart.
"Ugh!" Frieza grunted as he flew backwards. Panting, Rogue turned back into her human form, losing all of her power using the roar. Getting up, Frieza looked around at the damage Rogue did.
"Well, well," Frieza said, walking up to Rogue. "What have we have here? Oh wait! I know! A foolish human trying to defend her doomed planet. If you didn't attack me, I would let you join me, but you were foolish." Turning away, Frieza used his Death Ball to destroy the pathetic little planet. Going into his spaceship, Frieza ordered his men to get away from the planet.
Rouge, using the last of her energy to stand up and yell,
"FRIEZA!"
Frieza, watching from above, smiled as the planet blew up into nothing.
Well how was that? If you want, you guys can give me a few tips.
