In his awakened form, little of Kaleo's appearance changes. Of course, his wings are only present in his awakened form, small and adorned with silver blue feathers. However, should Kaleo come into contact with water, his skin will be slowly covered by shimmering blue scales. If exposure to water is prolonged, Kaleo's feathers will molt until they are bare bone, and eventually his form will shift
, condemning him to live within the water. Even so, the bones of his wings will remain.
As a siren, Kaleo has the ability to entrance whom he wishes with his voice. All human minds are bendable to his will. However, the minds of his fellow beasts are another story. Kaleo can only compel awakened to come to him, and little to nothing more. All humans, and many awakened, will feel a strong sense of attraction to Kaleo should he sing for them, often leading to a deadly infatuation.
Kaleo is very loving individual, with a weakness for children and animals. He will care for others before himself, despite his natural selfishness, which he is quite ashamed of. Truly, he only cares for others and animals in hopes they might stay with him; love him. Kaleo is a very good listener, and often doesn't sign or write much, choosing to simply reply with facial expressions. Kaleo can be quite the shameless flirt. When he sets his eyes on something, whether it be a person or not, it's very difficult to switch Kaleo's focus. His thoughts will be tainted with the object of his desire until he's able to have it.
Kaleo is mute, his voice sealed away with his true form. He reads lip rather easily, and is fluent in sign language. Kaleo loves flowers, and is quite the gardener; his yard is home to a greenhouse larger than his house.
