Liner Fusion Nelson Kaiser The word 巨船 (Kyosen) actually means Ocean Liner. Though in this context, it can also mean a gigantic ship in literal term. The word 合神 (Gasshin) is a play on the word 合身 meaning Fusion or Union. It's a typical term use in some mecha anime/shows for machines (or small robots) combining into a bigger robot. This particular Gasshin (合神) is stylized replacing the last word with "神" (God) for cool factor.
