The fusion of the five Space Pirate Seacons results in the mighty God Neptune (ゴッドネプチューン Goddo Nepuchūn). A powerful force few can oppose, when all else fails, he is their ultimate weapon. Halfshell seems to be the dominant personality in the fusion but certain traits from each crew-member occasionally show through. The four members besides Halfshell form the limbs, but it's a lot tougher on those who become the legs, which sometimes leads to arguments, so the combination doesn't go very well. Their major disadvantage is the flighty Scylla, who'll occasionally leave the combination to do her own thing, leaving the Space Pirates wishing they had a peg-leg, instead.
