In Batman '66 Meets Green Hornet #4, the Dynamic Duo confront the Green Hornet and Kato, who appear to be robbing the Gotham City National Bank. This turns out to be a clever ruse to track General Gumm and the Joker, who are after a priceless coin collection. The issue features a showdown between the two heroic teams, culminating in Batman and Robin falling into a trap set by the villains. This issue is notable for continuing the beloved 1966 television series' crossover continuity with classic villains and the creative team of Kevin Smith and Ralph Garman.
