Shapechanger

Shapechangers are gifted with shapeshifting, able to become whatever's needed. In the rare circumstance, a Doppelganger or something of the like has children, you would have the ability to change your form to suit your needs.

Minor Change

You can change your eye color, hair color, length of your hair, or anything else deemed minor by your DM. This lasts for an hour. Your features will slowly fade back to normal.

Also, you gain access to these spells. Disguise Self, Alter Self, Seeming, Shapechange, Polymorph, and True Polymorph

Read Thoughts

You have the ability to magically read the surface thoughts of one creature within 60 ft. of you as a bonus action. The effect can penetrate most barriers, but 3 ft. of wood or dirt, 2 ft. of stone, 2 inches of metal, or a thin sheet of lead blocks it. While the target is in range, you can continue reading its thoughts, as long as your concentration isn't broken (as if concentrating on a spell). While reading the target's mind, you have advantage on Wisdom (Insight) and Charisma (Deception, Intimidation, and Persuasion) checks against the target.

You can use this ability a number of times equal to your charisma modifier per long rest.

Animalistic Shifting

At 14th Level, you gain the ability to manifest some beast's features into your form. You can manifest wings, fins, horns, and claws. The wings (feathered, insect-like, doesn't matter. Your choice.) grant you a flying speed of 30ft. Fins (whatever they look like, doesn't matter. Your choice. You will have one on each limb, though.) give you a 30ft swimming speed. Claws (again, doesn't matter what they look like.) give you a 1d8 + dex damage modifier to your unarmed strikes. You can ram people with your horns (hey guess what, it doesn't matter what they look like. Your choice.) dealing 1d6 damage on a hit. These last for 1d6 hours, or you can dismiss them. At 14th level, you can shift two features instead of one, and at 18th you can shift all four.  

Shapechange

At 18th Level, you can use your action to polymorph into a small or medium humanoid you've seen, or back to your true form. Your stats, other than your size, stay the same in each form. Any equipment you are wearing isn't transformed. You revert to your true form if you die.
