I recently purchased a UK-exclusive Batman & Superman annual from 1974 and it features original prose stories including one where Superman fights a villain called the War Lord and Mayor Lyle Campbell of Metropolis appears. It seems there is not much effort on the Internet to chronicle Metropolis's mayors. I'm more of a Gotham man myself, but here is what I have for Metropolis mayors:
- Hansen (Superman #6)
- Worth (Action Comics #32)
- Phil Garson (Action Comics #37)
- Bragg (Superman #35)
- Caldwell (Action Comics #95)
- Mr. Mxyztplk (Superman #96)
- Harkness (Superman #263)
- Lyle Campbell (Superman & Batman Annual 1974)
- Summers (Superman #357)
- Frank Berkowitz (John Byrne's Man of Steel)
- Bradford Sackett
- Fleming (black female from Nick Spencer's Jimmy Olsen)
- Maxwell Minor (Morrison's Action Comics)
- Rob Morrisroe (New 52 Superman)
- Hopkins (Bendis Superman)
Just thought some fans might find this interesting. Any others not on this list?
