Linker3 started off as a land linker to a water linker same with the body it was the battle ship then changed it to submarine ish, last picture is the old versions. Also in the video for linker3 i explain that the trident can be summoned from the ocean and/or lakes, the pilot is also not human, the black square piece on the head as an eye it represents a eye patch but also its targeting system in the combined form.
Old version
