Any tougher than Smallville's Supergirl? We don't think so.

Laura Vandervoort played Supergirl, perhaps the toughest blonde of all.

Don't try to sneak up on Laura with your hunk of Kryptonite, because she has a real second-degree black belt.

On the show she was Clark's cousin, Kara who was also born on Krypton. She had all of his powers plus the ability to fly.

Even on "V" she was out of this world.
