Karl Franz (mirror)

Memory Beta, the wiki for licensed Star Trek content.

In the Mirror Universe, Karl Franz was the first commanding officer of ISS Enterprise (NCC-1701) and was assassinated in due course by Christopher Pike (TOS novelisation Mirror, Mirror).

This seems to indicate that Franz' counterpart was, in fact, Robert April.
