Slimer (LEGO Dimensions)

Abby Yates, along with her fellow Ghostbusters, attempted to capture Slimer in New York City. After Slimer broke free, Harry Potter subdued him with his wand while flying past on a broomstick.

He later charged into battle alongside Scooby-Doo, Harley Quinn, Abby Yates, the Doctor, Gizmo, Finn the Human, Jake the Dog, and Harry Potter in the Land of Ooo. (WC: New Adventures Await!)
