Fluttershy

Jeff was walking to the training area, but as he was doing that, a pony that looked exactly like regenboog Dash was waiting for him.

Jeff: *Continues walking to training area*
Rainbow Dash: *Jumps out of corner, and tries to kick Jeff*
Jeff: *Dodges regenboog Dash, and punches her*

Then all of a sudden, the pony that looked like regenboog Dash turned into a robot.

Jeff: Wait. What?
Proxy: Good afternoon. My name is Proxy, and I have been designed door Twilight Sparkle to assist u in whatever jobs she gives you.
Jeff: Well, I didn't think she would create a robot that would attempt to kill me. *Sees changeling*...
