I think a kaoani rabbit / bunny power could be cute, but I would love to visually see what it is you have in mind. Would it be more of an Easter Bunny with bright colors, or just a standard rabbit?
I recognize these items are in your post, but having them listed clearly with visual aids are very helpful in a post like this!
Furthermore, I would highly discourage editing your post to an entirely different concept - you are free to make multiple topics. I liked the idea of a skull power more than the idea of a rabbit power personally.
