The Doctor fluttered outside the burning TARDIS. "Hey, Pikachu!" said Ash. "It's a new pokemon! Let's catch him!"
"No, no, no!" said the Doctor. "It's me, the Doctor!"
"You're not the Doctor." said Ash. "The Doctor isn't a pokemon."
"I changed." said the Doctor. "After I- uh- Wait, what happened again? Sorry, it's regeneration after-effects. I can't remember what just happened.
"Well," said Ash. "Pikachu,-"
"OH YES!" said the Doctor. "That's right! Pikachu shocked me, and I began to die! But I'm all better now! I regenerated, and changed my physical- *COUGH!*" The Doctor coughed up some golden dust.
"What was that?!" asked a surprised Ash.
"Whoops." said the Doctor. "Hold on, I'm still regenerating. My body's finalizing it." His hands glowed for a second, and he coughed up more golden dust. "There we go, ha ha!"
"So, what happened in there?" said Ash. "The windows shattered to pieces!"
"Oh, did they?" said the Doctor. He turned around and looked at the windows. "Huh. Well, long story short, I exploded, and now I'm a pokemon."
Ash remembered the sonic screwdriver. "Hey, what was that blue flashlight, anyway?" he said.
"Uh oh." said the doctor.
"What?" said Ash.
"NO, NO, NO!" the Doctor screamed. "I left it in the TARDIS! She won't let me back in!"
"Who won't let you back in?" said Ash.
"The TARDIS!" the Doctor replied. "She's still rebuilding! Stupid me! Oh, whatever, the screwdriver's probably broken, anyway."
"What screwdriver?" asked Ash.
"My blue light-stick thing." the Doctor said. "It's called a sonic screwdriver."
"Um, okay." Ash said. "NOW WHERE'S THAT DOCTOR GUY?! IS HE DEAD, OR WHAT?!"
"Kid-," the Doctor began to say.
"It's Ash." Ash said.
"Right, right sorry. Look, Ash. I'm the Doctor."
"How can you be that guy from a minute ago?!" Ash demanded.
"Well Ash," the Doctor began. "Gosh, am I gonna regret this…" he whispered to himself.
The Doctor fluttered up into the air a bit. He pointed his head down, aimed it at Ash, and without warning, head butted Ash square in the forehead.
