I do not own the Avengers, Doctor Who, or any of its characters. I just thought this would be cute.
The Avengers were sitting in the living room of the Avengers Tower on Halloween, giving out candy to trick-or-treaters. Steve heard a whirring sound coming from the street. He walked to the window, and saw a big, blue...police box. Like, from Britain. How did it get here? Steve wondered. Then, the doorbell rang.
When Steve opened the door, a tall man with a bright red bow tie and a fez yelled,"TRICK OR TREAT!" while a woman with bright red hair and a man with brown hair ran up behind him. "Doctor," the woman said,"Why are you trick-or-treating? It's a kid's holiday, and the last time I checked, you're not a kid." "Oh, Amelia," said fez-man,"It's free candy! I am getting FREE CANDY. It's fun because it is innocent." With that said, fez-man stuck out his tongue at the girl and smiled at Steve. By that time, all of the Avengers had joined Steve at the door. "Who are you?" Natasha asked. "Sorry! Forgot to introduce myself. I'm the Doctor!" fez-man said," This is Amy and Rory." The Doctor stepped through the door and looked around. "A very nice space," the Doctor sighed,"too bad it's not bigger on the inside." Ignoring Tony's confused and furious looks, the Doctor turned around and drew a metal rod...thingy. He pointed it at Steve and pressed a button. A noise was emitted, then the Doctor flicked his wrist and read something on the rod. "Ah, the super soldier serum," the Doctor whispered," Very easy to re-create...if you have the right supplies." Steve looked stunned, Bruce looked awestruck, Natasha and Clint looked suspicious, Thor looked so happy, and Tony was still pissed about the 'bigger on the inside' comment.
"Thor! It's nice to see you again." the Doctor exclaimed,"Is Asgard still rebuilding your hammer? I'm sorry I broke it." Thor swept the Doctor into a bone-crushing hug. "All is forgiven, Doctor of Gallifrey. We are still in your debt for chasing those metal contraptions away. You look different. Have you regenerated again? How is Rose of Tyler?" The Doctor's twinkling eyes turned dark for a moment, then brightened up. "The Daleks? Oh, I've faced them before. Yes, I regenerated, and Rose, she's in another dimension, for her safety." "Is Gallifrey safe?" Thor asked, looking sad. "Oh, Thor, I've told you this." The Doctor sighed,"Gallifrey is in the Time War. It was Time-Locked. Gallifrey is basically destroyed. Well, it was nice to meet you all. Must be going. Hang on... would you all like to see my TARDIS?" "Oh, friend Avengers!" Thor exclaimed,"You must see his Time and Relative Dimensions in Space! It is amazing!" The avengers nodded their assent, and the group walked to the police box. "Ladies and Gentleman!" the Doctor exclaimed,"Welcome to my TARDIS!" They all stepped inside.
AFTER
"WOW!" Tony and Bruce were still in a sort-of semi shock after stepping into the box that was bigger on the inside. They couldn't believe all the sciencey things in there. Steve was amazed. They travelled back to the end of the war, and he saw his team again.(They didn't see him, though.) Clint and Natasha asked Thor," How do you know the Doctor?" Thor replied," He saved our race from the metal beings called Daleks. He is also very unusual. Just then, a computerized voice yelled, "EXTERMINATE! EXTERMINATE!" "Oh, great," Thor sighed,"The Daleks are back."
