Machines

Throughout the series, there have been various Machines that have been built, most of them by Edd. Most of Double D's machines are somehow involved in Eddy's latest scam. One notable exception is in the episode "Cool Hand Ed", when he is forced to construct a plane on the roof of their school by Eddy to escape the school.

There are four distinct categories of machines — they are Normal Machine, Vehicle, Structure, and Weapon:


 * The "Normal Machines" are generally devices like Double D's Jet Pack or Rolf's Power Generator. They are pretty much just normal machines that each have a certain function.


 * Then there are "Vehicles" such as Eddy's Professor Scam Flyer or The Kanker Sisters' Pirate Ship. The vehicles are almost always used for transportation, although some are used for more sinister purposes.


 * The "Structures" are built for different uses, but are generally used for scams. They are essentially the various structures used as parts of scams, such as the Sky Elevator.


 * The "Weapons" are, of course, weaponry. They are used for fighting. Many of them appeared in "The Eds are Coming" and their intended use was for agains the "aliens".
