The Dai-Gunkai resembles a massive centipede or some other kind of worm, with a long body and many small "legs" (actually fins) lining its sides. The bow of the vessel is shaped like a grinning face with eight eyes and a pair of scythe-like pincers. The bridge resembles that of a submarine, but is decorated with four eyes and has functional segmented arms with huge lobster-like claws.
