Title: Clash of the three Beasts
You start off at home, in your room, and you hear three terrifying roars, each one sounding different. You rush downstairs to see what your mom had to say about it, but she claims she didn't hear anything. You rush outside to see if anyone else heard it, but it's only you. You run into either Gary or Misty, depending which hero you chose to be. Gary/Misty claims she/he heard it too. You rush to Professor Oak's Lab, where he says that the roars were just a figment of you imagination. You nod, but Gary/Misty storms out angrily, sure that he/she is right. You start to leave when Professor Oak calls you over before you leave. You run over to him, and he asks you if you have a Pokémon. You say no, and he hands you a Poke ball. If you chose to be Misty, you get a Poliwag. If you chose to be Gary, you get a Umbreon. He tells you it's a Pokémon he caught, and he's giving it to you. You gladly take it, and he hands you a Pokedex and 5 Poke balls. He also hands you a gym badge case, and tells you to head to Floria town, where the first Gym Leader is. You start going to Floria town, when Gary/Misty confronts you. He/she is still upset, and calls you out for not backing he/she up. Then he/she challenges you to a battle, and you except. You win, and Gary/Misty storms away. You then start heading to Floria town.
The Floria gym leader is happily awaiting challengers in the Gym, so you head on in. You spot Gary/Misty currently battling the Gym leader, and is creaming the Gym leader. Gary/Misty eventually wins after you check out the Pokémon center and Poke Mart. After the win Gary/Misty spots you. Misty wishes you good luck, and Gary just ignores you. The Gym leader's name is Leon, and has grass type Pokémon. After you win, you get the badge, and head out of Floria town to the next town, Gellion village.
At Gellion village, you realize the Gym Leader, Zane, is very sick. You are asked to find a plant in Treewood forest that can heal the sickness. When you find the medicine, you hear one of the roar's again. You head in it's direction, to find a Rayquaza destroying part of the forest. You walk out to confront it, but someone else beats you too it. The person is quickly blown away by Rayquaza, so you try to confront it. You walk up to it, and it roar's. But then looks at you for a while, and fly's away. You shrug, and continue to get out of the forest. You quickly get out of the forest, and give the medicine to Zane. After defeating Zane, you get the badge and walk outside. Gary/Misty is waiting for you, and challenges you to a battle. You accept, and beat he/she. Gary/Misty claims that it was just dumb luck you won, and runs away. After that you head to Clacia town.
At Clacia town, you quickly do a quest for the Gym leader, Kate, by tracking down a theif and sending him to jail. You begin to challenge her, but Gary/Misty runs in front of you and asks Kate first. Kate agrees, and Gary/Misty happily runs into the gym to wait for Kate. You ask to battle her after Gary/Misty. She accepts, and you walk away. You look around the town until you come across a girl name Celest. She tells you that she has been hearing mysterious roar's, and you tell her about seeing Rayquaza. She gasps, and tells you a legend. The legend is three great legendary Pokémon will appear and start destroying the world bit by bit, and that it's unstoppable. Except, three warriors
with three legendary Pokémon that can save us will stop them. She tells you the three warriors will be able to hear the roars, and that you Gary/Misty and herself are the warriors. She tells you to watch out for the three legendary good Pokémon and that you have to catch one of
them. After that you battle the Gym leader and get the next badge.
Once you beat the seventh Gym leader, you find the three good Pokémon. Entei, Raikou and Suicune. You get to choose which one you want to catch, and catch it. After that you see that Gary/Misty was following you and catches one of the Pokémon that you didn't catch, and Celest catches the last one. You head to the last Gym leader in Frosnow village.
At Frosnow village, you beat the Gym leader Chill, and head to the Pokémon league. On your way there, You are called by Professor Oak to come back quickly. After that you head back to your town, which is on fire and completely destroyed. You, Gary/Misty and Celest get rid of all the fire, and you try to find your mom. You look around the whole village, and she is nowhere to be seen. Professor Oak tells you that the legendary Pokémon Groudon came and covered the town in fire and destroyed it and took you mom. You take Professor Oak's bike and start riding to a boat dock in Floria town.
At Floria town, you get on a boat with Gary/Misty and Celest and start riding to Lava Island where Groudon's cave is, when Kyogre confronts you. You get out your Pokémon and face Kyogre, who you defeat and Kyogre runs away. Gary/Misty heals you, and you continue to boat to the cave. At the cave, you realize Groudon went to the Eclipse shrine, so you follow it to there.
At the Eclipse shrine, Groudon Kyogre and Raquaza are waiting for you. You run up to one of them, and face them. You can either catch or defeat them. After you catch/defeat them, you head to the Pokémon League, where you face the champion Kion. After defeating Kion, a man dressed in black comes out. He claims he's been watching you, and he's the one behind Groudon Kyogre and Rayquaza starting to destroy the world. Celest interrupts and claims that it was in the legend and he had nothing to do with it, but in his hands he held a missing part of the legend. Celest tears it from his hands and reads it. She tells you that the missing part was that after defeating Groudon Kyogre and Rayquaza a great evil will come. You face the man in black, who has lvl. 80-85 Pokémon. After defeating him, he claims he will come back in 100 years and haunt your descendants. He then disappears, and you become the champion.
After finishing the main story, you will go one hundred years into the future and face the man in black again, stopping him from haunting your descendants. But this time, he has a whole crew who tries to stop you. You go from town to town, that looks way different, tracking the man in black. Each time you get to a town, either a girl name Krystal, a man named Ruff, and a woman named Valerie will confront you and challenge you to a battle. You obviously win. When you reach Frosnow, you finally face the man in black again and defeat him. After that you send him into a vortex that traps him forever in a frozen world. You then go back to your own time.
