History of Black Death Destroyers

invid_scorpion2a.GIF (68282 bytes)With the design of the Black Death Destroyers, the Invid Regent ordered a mecha so powerful that it could engage multiple REF mecha and come out victorious.   This mecha, armed with the most powerful weapons and sensors ,would become the command mecha for his elite forces.  The Invid research teams did not disappoint him.  The Invid Giraa Command Mecha was armed with no less than 5 PL-5X, plasma cannons found on the shock trooper, and 16 PL-3L, plasma cannons on the armored scout.  A volley of any of these weapons would bring an REF veritech to its knees.  The Invid Giraa was given the Invid's first missile launcher system, the IM-10, mainly to use against incoming missiles but it could be used to engage the enemy at extreme distances.  To guide these missiles a primitive radar system was added.  In addition to the formidable ranged weaponry, four combat claws were added to rip apart any mecha foolish enough to engage in melee combat

The Invid Giraa Command Mecha proved to be the most powerful Invid Mecha fielded by the Invid during the wars with the Robotech Expeditionary Forces.   However, the Scorpion as called by the REF, also proved to be extremely difficult to produce.  For every Giraa Command Mecha approximately 100 Invid Troopers or 50 Shock Troopers could be manufactured.  As a result only approximately 1,000 units were created.  The Giraa was for the exclusive use for the highest ranking stage four Invid in each hive or members of the elite Protoculture Death Squads formed on Optera.

The design proved to have some serious problems.  First and foremost, the Giraa was severely underpowered, although four 4 x Zyerri protoculture generators were included.  As a result the mecha could not fire all its plasma weapons in a single volley.  Secondly, the missile system proved to be extremely inaccurate to the point that its primary purpose of anti-missile protection was a wishful thought (game terms:  will only strike mecha on 10-20, and missiles on 18-20).  Finally, the REF forces took advantage of the weakness built into all Invid Mecha, that of the sensor eye.   There are countless cases of Giraa command mechs destroyed with a single shot through the eye without any damage to any other location.

A majority of the Giraa Command mecha were destroyed during battles with the REF; however, no less than 10 units were spotted with the Invid Regis during the occupation of Earth.  REF intelligence believes that the Invid Regis was examining these units as possible command mecha for her own stage 5 Invid; however, she turned towards the Royal Command Battloid as the incredible cost of production was too great even for her own tastes.

  2. arm_scout.jpg (23653 bytes)FOUR PL-3L PLASMA CANNONS: The Invid Scorpion has four plasma cannons mounted on each of the four arms..  Each cannon is the same design as that on the armored scout (see picture above).  All the plasma cannons on each of the arms are target together.


  3. SHORT RANGE MISSILE SYSTEM IM-10: The Invid Scorpion has, for the Invid, a revolutionary short range missile system


  4. HAND TO HAND COMBAT:.  Like all Invid mecha the Invid Scorpion possesses a considerable ability to engage in hand to hand combat
