Meet Kara Krypta, the Mare of Steel ;3  
(Yes she is based of Supergirl lmao)
 
A seemingly normal earth pony reporter, this pony is apparently the last survivor of a different planet out in space (Although there are reports that there is another stallion who also survived), and now lives amongst the ponies of Equestria.
 
She has dedicated her life to helping out others, and is seen as a hero by the public.  
She has super speed and flight, heat/x-ray vision, freeze breath, super strength, and super hearing. She is also completely invincible, but she can be hurt by these glowing green rocks, rumoured to be from the remains of her home world.
 
Although she is a kind soul and is willing to help alot, she can get very cocky and arrogant when she is doing her superhero duties and fighting criminals, making her get distracted.
 
She and Barbat Gordon/Bat-Mare know of eachothers secret identites, and have a good relationship, and are curretnyl a couple.  
Both of them are considered to be a crime fighting duo, and when they are not out fighting crime, both of them like to act like nerds and talk about cartoons and vidoe games and ships X)
