Why bother with cyber-augmentation when at high TL bio-augmentation can do the same if not a better job?
Bio-modification could alter your eyes to allow you higher resolution vision, seeing more of the em spectrum (if a Terran animal has the feature find the gene and engineer it into the recipient).
Animals can be found with superior organ function - copy it. Add an extra heart to boost endurance and provide redundancy. Improve clotting. Strengthen bone and augment muscle.
Venom producing glands grown beneath the nails or teeth. The bio-electric generation of electric eels.
You could even copy the cuttlefish's chameleon like ability (it is better at it than the chameleon).
The advantage of bio-engineering is you re-grow damaged parts rather than needing a machine shop, and all you need to do is eat (although a little photovoltaic mod may help you out on that as well) rather than plug yourself in or rely on the batteries not running out
