They are brothers, and were formerly enemies. They started Davenport Industries together in 1992, but Donald kicked Douglas out after Douglas illegally created bionic superhumans. Even though Douglas was accepted again, he has a tendency to go behind Donald's back and do things, though Donald is somewhat used to it.

- Donald and Douglas will have the same arrangement as they did in Season 4 of Lab Rats; Douglas does work at Davenport Tower, while Donald is out, especially due to taking care of Tasha until Naomi is born.
