The other end of the spectrum is the worst Tauric creature I came up with, an Orc Centipede. Light blind, stupid, and ugly from orc, slow and weak from the centipede plus you lose the poisonous bite.
I did make a group of Tauric Orc Scorpian that were a lot of fun, the Skorshien (Score Sheen) they had a climb speed and came down a hallway like the xenomorphs from Alien. The funny thing was, I made a huge sized Skorshien king, the party found him in the middle of the day fast asleep. One of the characters flew to the ceiling of the chamber and dropped a forty pound block of brass onto his head, killing him instantly. The moral of this story, never give a party a forty pound block of brass
