In "Micro Management," Skulker projects a hologram recording of Danny onto a rock in the Ghost Zone. The hologram says, "Maybe you need to rely on your natural abilities," and then Skulker blows it up with his new arsenal of weapons on his suit as a show of power.
In "Beauty Marked," the Specter Speeder displays a holographic map of "real-world items" in the Ghost Zone when Danny and Tucker are looking for Sam's location.
In "Kindred Spirits," Vlad asks the Maddie hologram to play a series of videos of Danny and Valerie in combat and then to analyze them. She returns that the data is inconclusive and that a "mid-morph sample" of Danny going ghost will be needed for Vlad to complete his clone of Danny. At the end of the episode, while Vlad's lab is being destroyed, the Maddie hologram tells him that she loves the Jack hologram, not him.
In "D-Stabilized," Vlad asks the Maddie hologram to scan Dani and then analyze the results. She returns that Dani's structural density is at fifty-three percent, then eighty-five percent, and that her ectoplasmic energy readings are unstable. At the end of the episode, Vlad vents to the Maddie hologram about the events of the episode.
At the beginning of "Phantom Planet," several Maddie holograms are put in charge of analyzing ecto-ranium for Vlad on his satellite in Saturn's orbit. They fight over who will get to deliver their findings to Vlad. Later, the Masters' Blasters play a holographic recording of Vlad for the people of Amity Park to watch. Later still, when Vlad tries to turn the Disasteroid intangible but finds he is unable to do so, a wristwatch-sized version of the Maddie hologram reports that the Disasteroid is made of ecto-ranium, which he cannot touch.
