Captain Planet and the Planeteers/Awesome

"Wheeler: Gi, you don't really want to do this! Gi: Yes, I do!"
 * Katara's not the only Waterbender you do not want to get angry. In the episode "Teers in the Hood," when Gi learns the identity of the gang member who shot and hospitalized her friend, she completely snaps and uses her ring to send him flying up a waterslide and down into a pool where she tries to drown him. Beware the Nice Ones, indeed!

"Captain Planet: (bearhugs Captain Pollution) EARTH! (drives them both through the Earth's crust) FIRE! (they reach the Earth's mantle) WIND! (flies back into the sky, swings Pollution around by his ankle) WATER! (throws him into the sea) Captain Pollution: (Captain Planet retrieves him) Oh, have a heart, Captain Planet! Captain Planet: Ah, you've had enough? Well let me hang you out to dry! (slams him down)"
 * Gi going all gangster when she takes the gun off Wheeler and intends to use it on who shot King.
 * The end of the episode "Teers In The Hood." The images of civil rights leaders are one the most powerful and serious moments in a kids' cartoon even to this day.
 * Ma-Ti punching out Hitler. If you know anything about one Colin Ross, this becomes all the more epic.
 * The epic way Captain Planet defeats Captain Pollution the first time.
