The AMX-009 Dreissen is a mass-produced heavy mobile suit introduced in the anime Mobile Suit Gundam ZZ. One unit is piloted by Rakan Dahkaran.
Designed based on the data of the MS-09R-2 Rick Dom II, the Dreissen is however much more similar in function to its distant ancestor, the MS-09B Dom, as it was designed with high speed ground combat in mind. Although larger than the Dom and Rick Dom II, the new materials used in Dreissen's construction make it much lighter and thus more agile. Unlike both the Dom and Rick Dom II, the Dreissen was designed with melee combat in mind, but it proved to be a versatile suit thanks to the triple beam cannons mounted in its arms. Although developed with an emphasis on ground combat, it can also operate in space without issues.
During the First Neo Zeon War, the beam cannons on the Dreissen's forearms have exposed power supply cables, which can render the weapon inoperable if the cables are damaged during combat. Later, the Neo Zeon remnant group, the Sleeves, resolved this weakness by housing the cables internally in the arms.
When Neo Zeon forces launched its war against the Earth, it rolled out a number of new mobile suits designed for ground combat and one of them was the AMX-009 Dreissen. Although initially produced in small numbers, the Dreissen's excellent performance and adaptability made it a popular and versatile mobile suit, and it was soon mass-produced for both ground and space combat.
