Almost, but not quite right. O'Niel did not create Hugo Strange. Strange is slightly older than The Joker, appearing in Detective Comics 37 or so (The Joker and The Catwoman both appear in Batman 1 which came out around the same time as Detective Comics 40... Wherein Clayface I debuts).Klaus said:Denny invented, among other villains, Ra's Al Ghul, Clayface II, Hugo Strange and Man-Bat.
