Basilisks are large, snake-like monsters. Their name means "little crown."
When the gigantes Polybotes walks past R.O.F.L., the goddess Iris' shop, the basilisks appear. Iris doesn't let them in and defends herself against the army with her rainbow. In retaliation, Polybotes releases three basilisks out of his hair and they circle the shop, not letting anyone leave or enter. Frank Zhang manages to kill them with some help from Gray, a gift from his father, Mars.
They are little green snakes with an expandable color of white spikes around its neck. They can breath fire and their touch is poisonous. They can be as long as a man's arm.
- They are able to spit fire and are very poisonous. When one simply touched Frank's bow, it disintegrated.
- In myths, they were said to have the power to cause death with a single glance.
- The basilisk are also called "KING" because it is reputed to have on it's head a mitre or crown-shaped crest.
- Weasels are deadly to them.
- The giant Polybotes can make them fall out of his hair.
- "Basilisk" in science refers to Basiliscus, a South American genus of lizard containing four species.
