Character: jade "cascade"
A female, indigo skinned, ex-human, anthro orca kaiju created by Rismic. She stands at 15 feet tall, which isn't large for a kaiju, but the character's creator wanted practicality over immense size. She has super strength, a body highly adapted for the water, and can fire a radioactive beam from her mouth. Jade is her first name and "Cascade" is what she is called in the media. Her life after her transformation is controlled by the military, who keep her away from the public by having her secluded on a private beach and a portion of ocean sectioned off for her, only letting her out to deal with monster attacks. As a result, she lives a lonely life as a kaiju.
This is the last character Rismic posted artwork of on her account before her death in 2015, but not the last she commissioned.
