The eponymous organisation to which almost all of the superheroes seen in this show belong. Its purpose is to oppose the show's villains as well as fighting for truth and justice generally.
Traditionally, the Justice League's members come together to oppose some threat that they would not be able to handle individually: a threat to the whole Earth, the galaxy or even the entire universe. The members, including the animal ones, carry small signalling devices which are used to alert the other members so that they can meet at the designated assembly place, the Watchtower. There, they have instruments to locate threats on Earth or in space so that they can then move to deal with them, making use of the League's vehicles if necessary.
