Check out this very detail "All Custom Body Skins" video created by youtuber XCVii007r1!
00:00 - Custom Cyborg Body (BP Cost: 0)
A unique cyborg frame, upgraded to aid Raiden in his fight against Sam and Desperado. Equipped with Blade Mode and able to absorb fuel-cell electrolytes from enemies via any high-frequency blade, it unfortunately lacks any kind of self-repair unit, meaning Raiden must manually extract repair material from his foes in order to recover from damage.
00:31 - Custom Cyborg Body (Red) (BP Cost: 15,000)
A cyborg frame with red artificial musculature that offers minimal defense and consumes considerable fuel-cell energy, but is highly effect at absorbing electrolytes from foes.
