Memento Mori

Memento Mori is a newly built particle beam cannon that was installed onto the lower orbital ring of the solar satellite system in Gundam 00. The cannon has the destructive yield of nukes (how many Hiroshimas is unclear) to instantly vaporize an entire country off the map. It draws power from the solar collection grid.

Memento mori is a Latin phrase that may be translated as "Remember that you are mortal," "Remember you will die," "Remember that you must die," or "Remember your death". It names a genre of artistic creations that vary widely from one another, but which all share the same purpose, which is to remind people of their own mortality.

History

Development

It's unknown when the Memento Mori was designed or built, but Innovator's Ribbons Almark forwarded the technology to the Federation for development. Wang Liu Mei was Ribbon's sponsor for the project in their mutual beliefs to Aeolia Schenberg's plan for planetary unification and preparing humanity into space.

Unifying Earth

Destroying Suille

To accelerate the unification of the world, Ribbons decided to activate Memento Mori to test its capabilities and wipe out the Suille Kingdom (last country(s) left to oppose the Federation) at the same time. A-Laws successfully vaporized the Suille Kingdom instantly with a single blast, nearly taking several nearby Federation Army units as well.

Assault on Memento Mori

The A-Laws had plans to eradicate any Katharon base they can find. At the same time, Katharon deployed their entire fleet to destroy the weapon. However during this time the Memento Mori showed that it was not only capable to fire on Earth but also into space. It used this ability to destroy several ships of the Katharon fleet.

The remainder of the Katharon forces were decimated by the A-Laws mobile suits defending Memento Mori, until Setsuna F. Seiei arrived in the 00 Raiser. While Setsuna diverted the defending mobile suits, including Healing Care's Gadessa, the Ptolemaios 2 moved into position to attack. After using Arios's Trans-Am to dodge Memento Mori's beam, Tieria Erde uses Seravee GN Bazooka II to blast a hole in the weapon's outer bulkhead, allowing Lockon Stratos to snipe its light resonance chamber with Cherudim's GN Sniper Rifle II. This caused a chain reaction that destroyed Memento Mori.

Aftermath

In the aftermath of the superweapon's destruction, the Federation Government publically announced that it was a simple satellite in geosynchronous orbit. This gave the A-Laws the leverage to take direct control of the regular army to enhance security, prompting discontent over a small faction of the military, who planned a coup d'etat.

Second Memento Mori

During the coup d'etat, in which the dissidents occupy the AEU's orbital elevator, the A-Laws unveil another Memento Mori. Setsuna and Saji sortie against it in 00 Raiser and destroy the second Memento Mori with an enormous GN beam saber, but not before it fires and causes the orbital elevator to collapse.
