Komkor 001

Komkor 001 is a Zerkalo Bloc Machine and walking Fortress sent to secure this earth from the monsters and fiends that menace it, acting not only as a gigantic support fighter, but boasting a command and general staff within it to give direction to it's forces.

Lore
Standard strategy doctrines guide the sequence of steps in every Zerkalo Bloc invasion. The first wave is led by brute force mecha that carve out a "landing zone" in the new dimension. When a relatively safe area is established, the leaders of the expeditionary forces arrive. These forward command and control mecha are not only staffed by expert pilots who understand combat on a massive scale, but they also command staff to plan the specifics of the invasion from a forward position. For such a formidable war as the Monsterpocalypse, the high command decided that their most decorated machine and crew would return to active service to ensure a great victory.

Trivia
