Isonade morph

Isonade (Synth)
Named after a legendary water-creature from Japanese Mythology, the Isonade was designed by an offshoot of the corporation who designed the Takko morph, and has similar principles. Cetacean morphs are rare and sometimes at a premium, even in aquatic habitats, so the Isonade is intended as a synthetic alternative. It obviously requires no gills or oxygen reserve, and is equipped both with an aquatic propeller system, a thrust vector for Zero-G, and the underside can undulate along the ground when out of water but in gravity. The morph is equipped with a number of features which can be enjoyed by aquatic uplifts and are useful, such as its eelware and electrical sense. With equipped Sonar and enhanced hearing, the morph is capable of "speaking" Neo-Cetacean, and can also use the Octopus chromatophore language with Chameleon Skin. As a final useful feature, the Isonade has two retractable arms, which can telescope, so the morph retains it's manipulators as needed. However, it's synthetic shell isn't as fully optimized for proper "swimming" as an actual Cetacean morph. Sadly also, the extensive adaptation and custom shell does make it quite expensive to produce.

(The Isonade is a morph I originally designed in a little jam to build a Cetacean-compatible synthmorph option over in the /epg/ community. This is a later reiteration with some refinement. Like many synth alternatives, the Isonade (named after a creature from Japanese Folklore as noted above - giving it an echo to the Takko) is expensive. But carries a lot of benefit, and can probably be more easily mass produced then possibly GRM-locked uplift morphs. The addition of snake was an idea I had because I didn't want it to be useless out of water, but Thrust Vector might not be universally applicable. So in a pinch the Isonade can scoot along a surface to move. It loses some of the massive swimming bonus for a better natural weapon, the shell armor and some great bonuses - plus no need to worry about breathing at all)

Prosthesis

Prosthesis (Synth)
In the decades before cyberbrain technology and mind uploading was reliable, the only recourse for persons with medical or job requirements to utilize a Synthetic body was the full-body prosthetic. This system actually extracts the brain of the subject and places them in a custom built synth shell, designed to mimic a normal body. Due to its use for security or medical purposes, Prosthesis also tend to come equipped with strong sensory enhancements and a fortified body, to allow the user to function at high potential, while also mimicking normal human functions. These improvements tended to make the models expensive. However, due to being an older design, the faces and expressions of the prosthesis tend to be vacant, doll-like or otherwise subtly off-putting to most transhumans. These days, Prosthesis are almost exclusively used by rich bioconservatives (usually for their intended purpose of medical replacement), or by morph hipsters who enjoy the throwback in terms of synths to using a human brain in a can.

(The Prosthesis is a morph design I've run a few revisions through. The concept was to utilize the Brain Box in a different way, and harken to a lot of earlier cyberpunk material with a wholly synthetic body which did not replace the brain. What purpose could such a design have? Obviously a full-body prosthetic - with the terminology borrowed mostly from Ghost In The Shell. Of course, making a good synth, especially having to re-add some implants normally covered by a Cyberbrain, makes a quite expensive model, masked or no. This fits the requirements of the setting, of course, and given advances in Synthmorph/Cyberbrain technology, such a specific caveat for the Prosthesis means they're likely to be uncommon and expensive to build - this style of design has fallen out of favor. Like a lot of Synths, it makes a decent start to a combat morph, but can be general enough that one might find a use for it multiple niches).
