Loki. If he doesn't find a way to mess it up, it's truly bulletproof

https://en.m.wikipedia.org/wiki/Sphinx

In Greek tradition, the sphinx is a treacherous and merciless being with the head of a woman, the haunches of a lion, and the wings of a bird. According to Greek myth, she challenges those who encounter her to answer a riddle, and kills and eats them when they fail to do so.

The word sphinx comes from the Greek Σφίγξ, associated by folk etymology with the verb σφίγγω (sphíngō), meaning "to squeeze", "to tighten up".
