Pokemon: I will save them all

Ash was a Pokemon trainer. He was a new trainer so he wasn't really strong. He went to see Prof. Oak.
"Prof. Oak I'm a new trainer so I need a good Pokemon to catch them all!" Ash said.
"I'm sorry Ash you're late so you can't have Pokemons. So I can't give you Pokemon."
"No! This is so cruel!" said Ash and he saw a Pokeball on the floor.
"Don't touch this Pokeball uncounscious pig!" screamed Prof. Oak and Ash jumped back.
"Why? Isn't it empty? Is there a Pokemon in it?" Ash asked.
"No... Yes no... This is very dangerous Killer Pokemon. I had it but I can't give to you because it's too dangerous!"
"No you will give it to me!" said Ash.
"No I won't" said Prof Oak and he hid the Pokeball somewhere so Ash couldn't take it.
Ash was so upset he started to cry.
"If you don't give me that Pokeball I will commit suicide!" he said.
"No are you crazy don't do that" said Prof Oak and then the laboratory of Prof Oak exploded.
There were screams and then nothing. Ash didn't know what was happening and THEY CAME.
Two bad guys dressed in black were theer. One didn't have hair and eyes and nose only a big mouth on his face. The other had very long hair and had tears of blood. He was holding a cut head of a man with glasses.
"Prof. Oak We know you have it give it to us now!" said Hairy.
"No I will never!" said Prof Oak and he showed to Ash where the Pokeball was hidden.
Ash ran there.
"Where are you going you little simpleton!" said the two man who started to run to Ash but Oak jumped on them and they fell.
Ash took the Pokeball.
"I have it!" he said;
"Okay this is soooooo good so now you must escape before they take it!" said Oak and Baldy hit Oak and Oak was uncouscious.
Ash ran away but the Pokeball fell and it opened. A... Pikachu appeared!
"Pi-ka-chuuuu!" Pikachu said.
"LOOK it is not what we want but we will take it" said the two men.
"Pikachuuuuuuuuuuuuuuuuuuuu" said Pikachu.
"Nooo Pikachu do go to them you must not because they are evil bad guys who killed people!" said Ash.
Pikachu stopped and then went to Ash and Ash escaped with Pikachu.

Ash was running with Pikachu and then he looked behind him and he saw Pallet Town was burning.
"I will avenge Pallet Town you evil bad guys"! said Ash
