Super Brawl 3: Good vs. Evil is an online flash crossover versus fighting game found on Nick.com, in which both heroes and villains from various Nickelodeon cartoons can be played as brawlers. The previous two "Super Brawl" games were made prior to Nickelodeon's work with the Teenage Mutant Ninja Turtles franchise. This is the last Super Brawl game in Flash, as Super hero brawl 4 was in html5, and Super Brawl Universe was first released on the Google Play Store.
Players are given a choice of characters, which includes the four Turtles and Shredder. They may also choose a male or female "Fan" - a human companion dressed like the character, that will jump in for a super "Fan Power" move upon filling a bar. The Fan Power moves replaced the Super Move from the previous Super Brawl games, as they are both very powerful attacks that require a bar to be filled up before they can be used.
Special combo move — This move is different for all characters. For Korra, it is Right arrow, Left Arrow, X, and produces an Avatar Blast which causes her to bend all four elements at the same time. For Amon, it is Down arrow, Right arrow, Z, and produces a Blood Bending Stun, a strong, quick blow to the opponent.
The special attack can only be used when the fan power meter is full. The effects vary from character to character, and when charged completely, the playing field is engulfed in lightning-like images along with a powerful attack. For Korra, the playing field is engulfed in gold-colored lightning, Naga runs across the screen, and a fangirl/boy (the choice is given at the start of the game) cheers from the side. For Amon, the playing field is engulfed in purple-colored lightning and the fangirl/boy shoots lightning at the opponent.
