The Deus Ex Machine is a form of Plot Device used by the Customercons for various nefarious purposes. Wielded by Franklin Delenor Roosevelt Minicon III, earl of ToeJaAm, a named lackey, it has been a vital part of numerous nonsensical plots and escapades. Because of its unpredictable nature, it is a constant threat to the Arbitrary Autobots.
Having examined the methods used by Some random guy called Megatron, the somewhat sinister and enigmatic leader of the Customerscons saw a flaw with his plans and devised a way to overcome them. Rather then building a new, tailor-made plot device every week, he would, instead, build a single plot device that would do everything that he might need it for.
Unfortunately, this resulted in a needlessly over-complicated and overly elaborate device of questionable functionality. Rather then being good at any one thing, it instead offers mediocre performance and questionable functionality, often breaking down or not working as intended. At other times, it will fire off randomly with unexpected results.
A good example of this was when Franklin Delenor Roosevelt Minicon III, earl of ToeJaAm was trying to use the Deus Ex Machine to lay a four-lane highway at the rate of a mile a minute. Rather the machine misfired, striking Fishimus Prime while he was dosed-up on Warm Flat Black Fuzzy. The result was the creation of Black Crystal Pepsi Convoy, an evil, soft drink-fueled clone bent on destrucity.
After this event, it was agreed that the Deus Ex Machine was far too dangerous to be used. So Franklin Delenor Roosevelt Minicon III, earl of ToeJaAm continued to use it.
