Green Lantern (real name John Stewart) is a minor character in Teen Titans Go!. His powers come from a mystical green ring on his finger that make him fly and create items to use against villains.
As far as Teen Titans Go!, Green Lantern makes a guest debut in "Real Boy Adventures" during the concert.
While Batman is performing a guitar solo to the crowd (assembled for a concert about Fleshy Guy being a real boy), Green Lantern can be seen pumping his fist to the music, along with other iconic DC Comics characters, such as Nite Owl, The Joker, The Riddler, and others.
Wearing a dark black jumpsuit, Green Lantern has a lot of upper-body strength. The color and wrists of his suit are colored a vibrant green, and on his hand is the infamous lantern ring. He is bald, and looks very serious/intense with his black moustache and beard.
