BU-17 (Bio-Unit #17) is an artificial lifeform that has lavender hair, faded greenish skin, pink eyes and hot pink irises, bloated stomach, and illuminates throughout her entire body, due to enormous amount of energy that was pumped into her. She stands about 6"1" and can levitate and can talk by telepathy. BU-17 has no evil intentions, but can be easily manipulated by whoever possesses her. 

After the Hazmat Bros gather DNA samples From Saint Zayan, Madam Rogue, Tauni, Selma, Angela, Ayame, Mei Lien, and many others, BU-17 was later created by Edom King Esau II to carry out one specific mission which is to destroy all the 12 Tribes of Yasharala. After absorbing so many DNA samples, she possesses such ridiculous amount of power to where she may be the most dangerous character in the Earth Realm. She contains so much power that she is a danger to not only all life on earth but to herself as well!!! Unfortunately, Edom King looked past the fact that BU-17's body is not stable enough to carry such enormous power and end results may be horrific

Fun Fact: Edom King used a DNA sample of his own niece to create a clone and that is how BU-17 was born
