The HGUC RX-78-JK Gundam Jackknife uses the HGUC RX-78-2 (revive ver.) and the HGBF Powered GM Cardigan as a base. Originally submitted as a build-off entry on r/buildfightsystem’s discord server, this is no ordinary Gramps Gundam! For the most part, it uses the RX-78-2 as the main body, however the GM Cardigan’s legs were added to it to allow for the ability to equip and purge the extra armor that was added onto it. In terms of weapons, it uses a modified beam rifle, two arm-mounted gatling pods, two beam sabers, a giant machine gun on its left side, and a beam ultrarifle on its right side, and two shields mounted on subarms. When the armor is purged, it switches to a simpler loadout of a beam spraygun, two beam sabers, and a small shield with a heat blade attached.
