As Derpy = the Galaxy-class USS Enterprise, all she’d have to do is just raise shields.
 

 
Never mind the ‘Fourth Wall’, Derpy can shatter dimensions#!
 

 
She can be in two places at once! And whilst on the Sci-Fi theme, if you’ve ever wondsered what “Babylon 5”’s Kosh looked like outside his Encounter Suit, sans the genetic manipulation of the ‘Younger Races’ by the Vorlons…:

‘Understanding is a three-flavoured Muffin.’ X3
 
#- As Derpy is blonde, I am now imagining her wearing a black Barrier Jacket, and wielding Bardiche in ‘Zamber Mode’: an energy blade that can cut through dimensions. [/“MGLNStrikerS”]

Wait!  
Why isn’t she burning at the touch of a Dalek?!

@Lunalove  
Given that her employee number is 1701-D, that seems an a-propos thing to say.

To paraphrase Cdr. Riker in “ST:TNG”:
 
‘Fate. Protects fools, children, and pegasae named Derpy Hooves.’
