Thursday Theatre!
In terms of speed, durability, and strength, Kara represents, arguably, the ultimate opponent.
Think about what the combination of speed, durability, and strength to such levels mean:
You can't hit her unless she allows you to.
You can't hurt her when you do.
And you won't have many options available if she decides to retaliate.
But Supergirl writers are a determined lot.
So re-enter now the rarest of the rare --
a non-powered villain with enough cleverness, resource, and luck to give our ULTRA-powerful heroine a legitimate challenge, SANS magic, SANS red sunlight...SANS kryptonite...
