We see a (Fe/C) Duck in a laboratory with a robotic arm and leg as he was working on a device with a screen on it. Then we see the front of him with special goggles over his eyes. Who is known as the Tech Genius Adventurer, F/N Duck. Then all of a sudden he hears a strange noise behind him, causing him to lift up his goggles and turn around.

Then out of nowhere we see a blue police box appear right in front of him, 5 feet away.

The door opens as we see a white duck with a white spiked up hair style wearing a blue suit, a red tie, red and white sneakers, and a brown trench coat.

???: (Nods) Doctor.

F/N: (nods) Doctor.

Doctor: Now, by any chance you wouldn't happen to have a-

F/N: Oh yeah. (Points to his right) It's, uh, right over there.

Doctor: Ah, brilliant!

The Doctor walks away off screen then walks back towards the police box with some sort of blaster that F/N made.

Doctor: And don't worry, I'll be sure to bring it back.

F/N: I know you will.

Doctor: Well then, Allons-y.

He shuts the door to the police box behind him as it takes off.

The blue police box disappeared right in front of him, leaving the Tech Genius Adventurer alone in his lab.

F/N: What a nice guy.

He turns around and continues to work on his device.

(A/N: And there's the introduction short! The reason why I made this now is because I didn't have any ideas until I remembered one. And as you can see it involves Doctor Who. David Tennant himself (The voice of Scrooge McDuck in this series) wanted to have a Doctor Who reference/Cameo in this series but we never got one, so I decided to do him and the rest of the Doctor Who fandom community a favor. So what did you think? Let me know in the comments below and be sure to use a Sonic Screwdriver on that vote button so others can see and I'll see you guys in the next chapter!)
