Siren was once a timid shark. Being sheltered his entire life by his mother he never swam out of his kingdom’s borders. Until Kappa came into his life he felt like he needed to keep everyone happy and not let his people down.

It only took an act of selflessness to show him that he can be his own person and not what everyone wanted him to be. 

Siren is however still timid around a few people and fellow sharks. But he can open up to anyone if he’s comfortable enough!
