I've been toying with the idea of creating my own series of kaiju-inspired creatures for a series of children's book illustrations that feature a tiny character known as "Cocoa Cub". Cocoa Cub is on a mission to learn about the monsters in his world by asking deep, personal questions without getting eaten or smashed. During a recent rewatch of the original Ultraman series, I was surprised to see how much the writers seemed to want to instill feelings of compassion for the kaiju, many of whom were interstellar outlaws, but also sentient beings.
I'm also tempted to submit one of these new concepts to the recent AAU Children's Book Club call for entries in spite of its nascent weirdness. Why not? Let's see what happens.
