Their most terrifying attribute was their innate petrifying gaze, which could petrify their prey upon eye contact, turning them into statues.
And these petrified prey were their most delectable feast.
Due to their natural talent, which was identical to Medusa's,
Medusa was incredibly fond of keeping such creatures as her war beasts, using her own petrified victims as their feed.
It was unclear whether it was because of this habit, but the Petrified Lizards raised by Medusa were usually larger than their wild counterparts and their petrifying gaze was even more difficult to resist.
Their drawbacks were equally apparent. In order to digest special prey, their bodies were uniquely structured. Their colossal bodies were also in a semi-petrified state, which provided them with strong defensive capabilities but also a terrifying weight, rendering their movement naturally slow.
Most of the time, they ambushed their prey rather than pursuing it.
