For changing appearance I came up with Biogenetic
Alteration, a.k.a. the Chameleon Effect. The sentient undergoes a series of chemical & nanobot treatments making their body mutable. For alteration, then DNA programmed nanobots are injected for the proper alteration of skin color & texture, hair changes, eye color, cartilage, scars, etc. The alteration takes at least 24 hours to safely undergo the processor to reverse it.. A DNA marker can also be added to disguise your DNA signature. I would say at least TL12.
