Broccoli

The Green Lantern is a superhero character whose powers are fueled by the creativity of his mind. But broccoli, also colored green, refuses to be outdone by any superhero. Broccoli, too, is creative in the ways in which it puts a stop to several types of cancer. Great in salads and flavor-soaked in stews, broccoli is the veggie of choice against tough cancers that need to be taught a lesson.
