The Majin genes have now been infused into your extensive cellular genetic makeup, with it gaining a new transformation, granting you access to a Majin form at will. This Majin from gives you the physical properties and abilities characteristic of the Majin race, including their unique rubber-like physiology and much more.
Your new Majin heritage also complements your existing genetic legacy. You retain all the abilities inherited from your genetic pool gained through Cell, the Frost Demon race, the Saiyans, and more.
You have the freedom to choose the appearance of your normal base form, but your Majin transformation must have some physical characteristics shared by the Majin race (pink skin, tail,,,etc).
