I liked Superman ( And Supergirl ) best when they had to use their brains to defeat a bad guy.
That was a GREAT lesson there : No matter how powerful you are, there is always someone out there MORE powerful than you.
Brains are required at that point..and it is best to be a quick thinker, as well!
Superman is the son of a scientist. Kara's Dad was no slouch in the brain department, either. That made them both smart before they ever became super smart.
