Dealing With The Joker

Back in the later 1960s, Joker had just become another clown that Batman faced.

But, he was due for a revival in a big way, and here is a look at two of the issues that established the new normal (if Joker could ever be considered normal) for the Clown Prince Of Crime well until the Crisis On Infinite Earths...

The Joker's Five-Way Revenge

Here, in Batman #251 (September, 1973), by Denny O'Neil and Neal Adams, this team did to the Joker what they had been doing with the Batman...took him back to his roots.  While still having the clown motif, Joker was also shown to be much more of a homicidal killer as he methodically worked his way through 5 of his ex-henchmen.

Also important here, is that the Joker establishes that he enjoys his battles with the Batman...

Death Has The Last Laugh

In Brave and the Bold #111 (February-March, 1974) by Bob Haney and Jim Aparo, the unlikely idea that Batman and Joker team up happens (especially with the new norm just established in the Joker's last appearance above).  Still, it happens, as Joker lets Batman know that he was innocent of murdering a family, and the two work together to find the killer.

Still, as always, the two spar and there's a twist at the end.

But these two appearances set a tone for the Joker, as well as giving him more comic exposure, leading to the introduction of Arkham Asylum in Batman #258 (October, 1974) where a Two-Face rivalry was established, as well as Joker's 9 issue series which kept the Joker in the public eye...but, sadly, the Joker series ended before its tenth issue could be published due to low sales, because the series missed one important fact...the Joker needs Batman to be successful, it was their epic battles fans wanted, not just the Joker's murderous mirth.
