The El Dora( Gun x Sword)
The El Dorado Five is an older Armor once piloted the team of Nero, Jose, Carlos and Barrio. It is composed of five separate components which can split off into individual vehicles. But the full power of El Dorado is unleashed only when all the pieces are assembled. The Armor mostly relies on hand to hand combat but is capable of launching missile attacks. It is also an energy guzzler and will not last long in prolonged battles.

Plan-1056 Codarl



The Codarl is an Arm Slave developed by Amalgam and is known to be the first to utilize their experimental Lambda Driver. Specific design data on the Codarl are not known, but in combat it has outclassed the M9 in both speed and agility even without using the Lambda Driver. The Codarl limbs were modeled after feline and insect legs giving it added mobility and jump distance. Its most distinctive feature is the pony-tail like attachment on its head, this does not appear to serve any other function than being a decoy.
