Scooby Doo Meets Batman
Kids love Batman and kids love Scooby Doo, so why not have them meet? This seems like about the reasoning behind the crazy cartoon crossover that was Scooby Doo Meets Batman, which had both Batman and Robin meeting up with Scooby-Doo and his friends in two separate episodes of The New Scooby-Doo Movies from 1972. It’s definitely a bit weird, and not exactly good, but at least the original cast of Scooby Doo is intact. And everybody loves Batman!
