The defenders

The Defenders is an anti-troll group started by Pac-Man. Known members include Leap Frog, Frogger, Pori, Batman, Arthur, Spyro, Cheetoman, Trix Rabbit, Doug, Skeeter, Hello Kitty, Kermit the Frog, Ronald McDonald, Vivian, Woodstock, Dexter and later Tails.

In Chapter 20 we learn that The Defenders isn't real. The whole organization is a part of Cheetoman's criminal empire and the other members are extorted into working for him.
