The Boohbah is unnaturally strong and indestructible. Therefore it has an increase in both aspects.

As Boohbahs are fear itself, they have a natural proficiency in intimidation.

As a Boohbah you can get all of creation to submit to your power. With just a simple word you can trick living creatures into completing your goals.

At level 10, by simply saying Mr. Man to any creature you can cause them to make a wisdom save of 10+prof. Bonus+wis modifier. On a failed save they polymorph into Mr. Man and must do your bidding for 5 hours. At the end of the 5 hours they repeat the save with a DC of 2 lower. This repeats until they are free from your curse.

As the alpha of creation and fear itself you know the five most terrifying languages. You speak, read, and write Boohbah - Abyssal - Deep Speech - Infernal - Primordial

At  level 20 the original Gods of the Boohbah grant you the power to indoctrinate others to the infinite expanse of familial bonds. Once a month you may hug (grapple) any bipedal creature and force them to make a Wisdom Saving Throw against a DC of 18 + Your Proficiency bonus. On a failed save they become one of you, resetting their level back to 1 and losing all their previous racial abilities in exchange to an everlasting devotion to Jumbah, Zing Zing Zingbah, Zumbah, Jingbah, and Humbah.
