New Body

It is not uncommon at all for any species to change body form many times across their life-span. The ease with which they can do so depends on the continuity's technology level. In some, changing bodies requires an extensive full-body rebuild and tends to be resource-draining and even dangerous. Sometimes, however, all it takes is to transplant their brain or personality program into a compatible new body. Other times, the existing body itself will be "reformatted" on the spot using a scan of a local compatible alt-mode.

Getting a new body sometimes also involves getting a new name.
