It's the Joker who so horrifically scars Alexander Luthor and then seems to shoot him dead... the Joker who did this.. in the 7th and last issue of "Infinite Crisis".. I have so many serious, serious, serious, majorly important thoughts about how this Joker was not written by Geoff Johns at all... not even slightly .. but was rather written .. I mean literally written .. by Phil Jiminez.. Phil Jiminez.. Phil Jiminez...
