Fued.

One feud I am familiar with is the feud between Autobots and Decepticons.These two  Organisms dislike each other because the Deceptacons want to harvest Energons energy for evil power, the Autobots want to make peace between each other and rebuild Energon. The Autobots and Decpticons show that they are in a feud by constantly fighting and killing each other. Trying to take over Earth while the Autobots try to save the planet and all the people in it. As a result of the feud, the Autobots defeated the Decepticons and sent them back to there home planet and some of the Autobots stayed on Earth to keep the humans safe. The fued will end when all of the Decepticons are of planet Earth and there is no more tormenting of the humans. It will be over when the Decepticons and the Autobots make peace.
