I am very impressed with the design work STO did for this species. It deviates from the novelverse but that never really felt right to me. I remember their creator from Deep Space Nine, Robert Wolfe envisioned them as being like the Hakazit from Jack L. Chalker's Well of Souls novels. He saw the Tzenkethi as being "heavily-armored lizard things".
I am excited to encounter them in game.
