A reporter suspected it was 1 of 4 best friends: Jack Wheeler (actually Wild Dog), Andy (a cop), Lou (another reporter) & Graham (a Fed). While the original min-series tried to play up the mystery of his real identity, it was always REALLY obvious.

AS far as I know Midnighter & Apollo are only in Stormwatch, which I think is on the chopping-block.
