Mr. Terrific: He's Good at Everything!

[Michel Weisnor]

I always loved the fact, Mr. Terrific believes in fair play so much, he uses it as his insignia.

Most of his appearances in JLA as part of the JSA teamups didn't emphasize the fact that Terry Sloane was good at everything.  He was simply shown as an athlete in a costume. They did give him the nickname "Man of a Thousand Talents" but never played that up much or even explained it.
