Disney XD's Lab Rats Wiki

Donglas (Don/ald and Dou/glas) is the pairing between Douglas and Donald. They are brothers, and are formerly enemies. They started Davenport Industries together, but Donald kicked Douglas out. Even though Douglas was accepted again, he has a tendency to go behind Donald's back, though Donald is somewhat used to it. Despite this, Donald leaves Douglas in charge of the Davenport Bionic Academy when he's gone.
