Izzy Davenport

Isabeau Henderson Davenport is one of the main protagonists of The Bionic Bunch. After Bionic Showdown it is revealed that she is the biological mother of Adam, Bree and Chase. Additionally, they learned that she is raising their sister. Out of their parents, Izzy is the only one who is called "Mom" by Adam, Bree,and Chase while Douglas does not get the privilege and called "Aunt Izzy" by her step-nephew and niece. Izzy is also best friends with her sister-in-law Tasha Davenport and they both share the maternal figure in the family.

In Season 5, Izzy becomes pregnant with Douglas' sixth child, Jackson, and her arch-enemy is revealed to be her younger twin sister Emma.

She also mentors her step-niece, Josie on how to be a better person and how to be lucky to have a brother as great as Leo, as she does not want Josie to end up like Douglas and Donald used to when they were younger.

Izzy married Douglas and agreed to genetically engineer children. While Izzy was initially with the idea to raise Ellie and her siblings as supersoldiers, over the years Izzy grew disillusioned with the idea after looking into the eyes of her four children when they were babies. After creating a fifth child,  she betrayed her husband to her brother-in-law, Donald, but took Ellie away. Though Donald and Izzy hid the children, Douglas gave daniel up for adoption and allowed Izzy to raise Ellie because Douglas never had the chance to make her a bionic chip.
