Leo Dooley

Leo Francis Dooley  is the protagonist of Disney XD's 2012-2016 comedy television series Lab Rats.

In Suddenly Bionic, Leo struggles with his bionics until Douglas helps him train with it. Of course, they come into conflict when he trains hard. In The Atypical Life of a Bionic Family, Leo is Lea Dooley, who discovers her step-uncle in her tep-faher's basement.

Canon History
He was the only son and eldest child of Tasha Davenport, the older half-brother of Naomi Davenport, the step-son and second-youngest child of Donald Davenport, the younger step-brother/cousin of Adam, Bree, and Chase Davenport, the step-cousin of Daniel  and Marcus Davenport, and the step-nephew of Douglas Davenport. Loyal, caring and intelligent, Leo is initially an outcast until he meets his step-siblings, Adam, Bree and Chase and grows up. His stepfather, Donald had a lack of trust for Leo due to his tendency to accidentally destroy things, but has started to change his opinion, as he made Leo the team's Mission Specialist.

Midway to Season 3, Leo becomes bionic after Douglas installs them to save his arm after it was crushed by a ceiling beam caused by Taylor when she blasted it on top of him and Donald put bionics in Leo's leg after it was crushed by a space elevator in an attempt to save Donald.

Personality
Leo sometimes feels overshadowed by his older siblings, similar to how Chase feels when Adam and Bree are praised more than him and how Douglas felt with Donald all of his life. This is shown in "Lab Rats: On the Edge," where he expresses hope that his siblings don't see him as just their little brother. After saving Chase and taking charge, Donald realizes Leo is ready and levels him up to mentor, where Chase tells Leo he is proud of his little brother.

Leo got a bionic arm in "You Posted What?" and became an official member of the team in "Rise of the Secret Soldiers." Apart from dressing in his Davenport bionic Academy uniform, Leo mainly wore his mission suit when he was out in the field with Adam, Bree, and Chase. He had a black leather jacket with a hood but the jacket's right sleeve was colored red to signify his bionic arm and black gloves with red outlining on it. Additionally, Leo wore a pair of black boots and pants, as well as black knee paddings for protection. In "On the Edge," when Leo was promoted to mentor, he had the mentor uniform that Adam, Bree and Chase wore.
