Basilisk (creature)

Basilisks (バシリスク Bashirisuku) are recurring enemies from the series. They are giant horned lizards with bulging eyes, although in several recent installments they have become more Anacondaur-like in their appearances. Their common threat is their ability to Petrify characters using their stare, although there are often times when this status is their biggest weakness. The petrification usually is gradual (similar to Condemned is with Death), but in some games it happens instantly.

Etymology
The Basilisk is a fictional beast that appeared in Medieval bestiaries, it is said that a single gaze to their eyes would kill or petrify the observer. It was supposed to appear when a chicken's egg was hatched by a snake or a frog (hence their reptilian appearance).
