Basilisk

Basilisks (βασιλίσκος in Ancient Greek) are small snake like creatures. Their names mean "little crown" and they are legendary beasts of Europe, and are said to have the power to cause death with a single glance.

History
The basilisk is called "crown" because it is reputed to have on its head a crown shaped crest. Stories of the basilisk show that it is not completely distinguished from the Cockatrice, another mythical beast. The basilisk is alleged to be hatched by a rooster from the egg of a serpent or toad. The reverse of the cockatrice, which was hatched from a cockerel's "egg" incubated by a serpent or toad. Sometimes it's used as a symbol of modern European mythology, without specifying any.

The Son of Neptune
Basilisks are first seen when Polybotes was walking past R.O.F.L., Iris' shop. Iris wouldn't let them in and attacked the army with her rainbow. In retaliation, Polybotes released three basilisks out of his hair and they circled the shop, not letting anyone leave or enter. Frank managed to kill them with some help from Gray.

Basilisks also appear during the battle at Camp Jupiter, in which Frank scares them off by transforming into a weasel.
