During the Great Collapse, she took it into her own hands to try to save as many of Venomia's residents as she could. Many could not, either passing during the collapse or ending up lost in the void of the multiverse, nothing more then a wandering soul. She blamed outside forces were the catalyst for the Collapse, and yet she wanted to know more about them.
Now stranded amongst the fragments of a shattered universe; without a place to call home, Meta took it upon herself to create a perfect world in her image. A universe where no one would hurt, only living in peace and harmony while she observed and studied the infinite sea of the multiverse and beyond it. As she continued to isolate herself and her world, she created the cosmiums to assist in further data collection and protection, and the Zodiac was established; a council of 12.
Constette realized that true perfection isn't a possibility and would attract the outside forces that Meta Blossom feared. She began to tamper and disrupt with her perfect world, not of an intent to ruin, but because she cared. Meta did not see it this way, and isolated herself even more, creating a mask to hide her identity.
