The Apsalas was only made as a test project, and its weaponry consisted soley of a pair of Zaku II D head vulcans. Its pilot, Mohammad Shahryar, took it to several combat engagements, but was only able to deliver a handful of aircraft kills with the behemoth. When the armor was taken back to Lhasa for an upgrade, Shahryar refused to pilot it again.

Constructed off the test bed Apsalus, the Apsalus II still incorporated basic Zaku parts and many of the same features as its predecessor. Ghinias Sahalin perfected Minovsky craft system this time around, making the Apsalus much more stable in atmospheric flight. It also incorporated an extremely powerful mega particle cannon, capable of blasting through thick layers of rock, reinforced metal, and even a mountainside. The Apsalus II is considered the foremost contender in real estate destruction.

Since the Apsalus's first test pilot, Mohammad Shahryar, was shot refusing to pilot it, Ginius chose one of his chief test pilots to fill the position. Lucas Marcolini, a man of mystery by most accounts, currently pilots the behemoth. Lucas has since become one of the Federations highest priority targets, responsible for the absolute destruction of Torrington, as well as for severely damaging Gibraltar. The Apsalas was grounded at the battle of Odessa, but Marcolini piloted a Zaku II at the battle, scoring several kills.
