Wild speculation theory here:
It's going to be some kind of special armor the whip up to Match the VF-27 (either as a counter to it or to fight vajra like it). The big guns are quantum beam guns, with the "power condenser unit" being a device to draw power from the mech to charge the guns. the wing cover things have extra engines for more power/speed (just like the VF-27 with it's 4 engines), Micro missile launchers just like the VF-27, and it looks like the nacelle over the wing gloves (where the normal boosters go) may have large beam guns (just like the nacelles on the VF-27).
