Despite the impression we were given in the first issue,
O.O. Heaven did return in the second issue of
Bunny, and once again in issue #4 before someone finally said
"Knock it off!" and he disappeared, presumably undercover or perhaps rotting in a 3rd world prison, awaiting the seemingly inevitable dark & gritty reboot.
Or maybe he just got fired.
