The Protodeka was a gigantic repulsorlift weapons platform with rapid-firing heavy turbolasers and deadly seeker missile launchers with rapid-fire ability. Designed by a Colicoid scientist, it also had a seismic wave emitter that destroyed anything within 10 meters.
The Protodeka was CIS prototype juggernaut designed by the Geonosians and the Colicoids. It purpose was to serce as mobile gound siege weapon. Despite having heavy armor, slow speed and a slow turn rate, it was armed with masive laser cannons and new lethal homing concussion missiles. Despite the missiles being slow, they had a long seek time till they became exhausted. The first prototypes were vulnerable from their rear and at point blank range. Thus the Geonosian attached to this added a special short range area effect siesimc pulse weapon that was capable of shattering any ground units within range.
The Protodeka first saw action on Raxus Prime where they were able to slow down General Kenobi's forces long enough to get pieces of the Dark Reaper off Raxus prime till they were destroyed. After that, they were then stationed on Thule to defend Kessia. They were however destroyed by Generals Windu and Unduli. After the Dark Reaper Crisis, the CIS stopped mass producing them, for they were to expensive to build.
