"Teen Titans -- Ghost! Part 1" is the seventh issue of the Scooby-Doo! Team-Up comic book series, and the first part of a crossover issue with the Teen Titans Go! comic book series. It was released digitally on May 5, 2014 and in print on May 7, 2014 by DC Comics.
Is Titans Tower haunted?! Robin calls in some experts - but when will Scooby, Shaggy, Cyborg, and Beast Boy stop chowing down on pizza and start looking for clues?
Running Gag: Starfire mistaking things for a game.
Starfire tells Daphne that she believes Robin and Speedy have vocal similarities referring to the events of "The Date" and both being voiced by Scott Menville.
Daphne notes that Robin acts differently around the Titans than with Batman. This references two episodes of the 1972's The New Scooby-Doo Movies: "The Dynamic Scooby-Doo Affair" and "The Caped Crusader Caper" which featured Mystery Incorporated teaming up with Batman and Robin, and the first three issues of Scooby-Doo! Team-Up which featured the two in their designs from the series.
When Daphne comments that Robin's voice doesn't sound like Shaggy's anymore, she alluded to the late voice actor Casey Kasem, who voiced both characters in the 1970s.
