In an alternate universe, Ohm was a mad Time Lord god. Savar met Ohm whilst searching for Omega within a black hole. (PROSE: The Infinity Doctors)
Behind the scenes 
Edit
- OHM was also a proposed (but never used) name for Omega, as the name when rotated 180 degrees forms the word "WHO". [source needed] Coincidentally, Ohm is a unit of measurement represented by the upper case version of the Greek letter Omega.
