Chagelings are a powerful race of evolving lizards. Their home planet is unknown.
Vary in colors. They have color coded orbs on their body.
Changelings are incredibly durable and can survive most things. They are too strong to control their own power, so they employ Regression to contain their power.
There are 3 stages of Regression that a Changeling can employ to supress their power. What is normally seen as a "Fourth Form" is actually just a Changeling's base form before Regression. As they grow weaker with each Regression, a Changeling will look less and less monstrous and powerful.
While not a full Changeling, dark FREEZA is the dark COUNTERPART of the legendary Freeza, who is a Changeling.
