INTRUDUCING N-GIRL! ( the "N" stands for nutrition ) The plucky heroine whos super powers are fueled by healthy good for you foods. (fruits, veggies, ect)
Carrots give her laser vision.

Milk makes her invulnerable.

You can porbobly guess what spinache gives her.

And just as healthy food is the source of her power eating junk food takes them away. (and waht kid DOESN't like junk food?






(this idea actually came to me in a dream.)
