Victory Gundam Side Story version
Crossbone Gundam: Skull Heart version
Hidden MSZ-010 ZZ Gundam head
Unit type: custom mobile suit
Armament: high mega cannon x 1, double beam rifle x 1, pincer claw arm x 1, peg leg beam machine gun x 1
Pilot: Grey Stoke (aka Judau Ashta)
Mechanical designer: Yuichi Hasegawa
Note: Perhaps the most unusual contraption in Grey Stoke's collected of salvaged mobile suits, the Gump is a rather confusing mish-mash of parts. The tube-shaped "mask" over the head breaks open to reveal quite a surprise - a MSZ-010 ZZ Gundam head underneath!
