Finiis'ral

From Memory Alpha, the free Star Trek reference

Finiis'ral was a stage in a Kriosian empathic metamorph's life that was similar to late-stage puberty. During the end of stage, a metamorph would morph and imprint for the final time, a process that took about two days, as the metamorph would reach absolute sexual maturity.

In 2368, Kamala was experiencing the final stages of finiis'ral when she was accidentally released from a stasis cocoon aboard the USS Enterprise-D. (TNG: "The Perfect Mate")
