They are light and energy in the shape of multi-colored butterflies. Sentient symbiotic life forms which, are a part of the Twacon species.
When call by a Twacon to help they can reform life into other things, as in their first calling they decompose the dead clones into new life, plants in the Bio-garden and recreate Dide into a new-born Twacon. This recreation happens whenever the butterflies are first called forth from the Twacon adult or child, that is how the species reproduces. Each Twacon reproduces only one pure Twacon, they can give birth to children but although gifted they will never merge with a dieing planet to become its heart and soul, the spirit butterflies re-energizing the planet.
They can change a person, such as Fred teaching them new holistic values. If called to judge and the individuals or animals are killing mulishly they are reformed into water, rock or even dirt. Anger and killing is evil energy and cannot be reformed into sentient life of any kind.
They can communicate with any creatures mind threw mind thought. They are never angry they are total love.
