MXYZPTLK: A fifth dimensional imp with powers that are beyond any in the Supergirl CW TV Universe! With a simple snap of his fingers, Mxyzptlk or Mxy can create reality as he sees fit. Cracking the Earth in two, rebirthing Krypton from its ashes, even ending reality as a whole are but a simple snap away for this villain. That said, villain is potentially a harsh term for Mxy. He is misguided and doesn't understand freewill and love but his intentions are to win Kara Zor-El's heart. His power alone is what makes him so dangerous. Luckily, 5th dimensional creatures only appear in our existence with a series of rules that they layout. This includes keeping a beings' freewill intact, and most importantly if they say their name (or write it) backwards, they are forced to return to their dimension.
