Basil

Basil is an elderly male basilisk who lives in the Reptile House in the Wyoming Menagerie.

Appearance
Basil is described as a "perfectly hideous giant lizard who was almost as long as Logan was tall". He has a spiky crest fanning around the top of his head like a small crown, and stumpy legs ending in thick claws. His scales are grayish-green with white spots as if "someone had splattered [him] with milk".

Personality
Basil is shown to be sleepy, and has many attributes that come from his old age.

Dragon on Trial
Zoe fed Basil as one of her chores.

Krakens and Lies
Basil breaks out of his enclosure in the Reptile House and tries to escape the Wyoming Menagerie by riding their zaratan. He gets off of the zaratan when Zoe, Logan, Blue, and Jasmin go into the Menagerie to stop him. Logan gets caught by Basil, and Basil attempts to kill him through hissing, but Logan is protected by his scarab. Marco then arrives, in rooster form, and crows to put Basil to sleep.
