Batman '66 Meets Green Hornet #2 2014

In Batman '66 Meets Green Hornet #2, the Fearless Foursome escapes General Gumm's sticky train trap. The Green Hornet and Kato temporarily subdue Batman and Robin to pursue Gumm independently. A major reveal sees Gumm partnered with the Joker, featuring Cesar Romero's iconic portrayal. Both heroic duos eventually converge on Gumm and the Joker, leading to a confrontation. This issue is notable for continuing the classic 1960s TV series' tone and dialogue, and for the unexpected team-up of two major villains.
