Dr.'s Black and White are a duo of characters from Phineas and Ferb and are a pair of characters that appear in the first season of The Knights of the Multiverse. They are a pair of twin brothers that work for the evil organization L.O.V.E.M.U.F.F.I.N..
In between experiments, Dr. Black took up a small acting role in several low-budget films, mostly in the role of an evil scientist (obviously). This started to cause tension between the twins, with White getting upset that Black was focusing more on some dumb acting career than their evil schemes. After L.O.V.E.M.U.F.F.I.N. was disbanded, Black went to focus more on his acting career while White was imprisoned with several other scientists.

Abilities & Equipment Edit
Like most of the other L.O.V.E.M.U.F.F.I.N. staff, both characters were never named in the original series. Also, it is possible that Dr. White was just Dr. Black miscolored, but for this series, they're depicted as being twin brothers.
