How to unlock the I Ain't Afraid of No Ghost achievement in SONIC UNLEASHED - Definitive Guide
The first place he appears is near the entrance stage in Spagonia - you will need to skydive from inside a tower and collect two ghosts.
The second is near the entrance stage in Adabat where you must collect another 2 ghosts which are relatively close together.
The trophy description is half-wrong, because you have to do a mission in Adabat. For you to net this trophy, you must have unlocked the Spagonia and Adabat hubs. Talk to Marcantonio during the day in Spagonia (he'll be near the Entrance Stage Gate) and he'll give you a mission involving ghosts. The day mission can be hard though. Take your time, stay in the middle and don't get hit by the spikes.

But that's not all. When you have completed the Spagonia mission, Marcantonio travels to Adabat. Travel to Adabat (make sure it's night) and talk to him again. He'll give you another mission of tagging two ghosts. Complete it and the trophy's yours.

Note about the videos: The Marcantonio missions will not be on the stage select screen on the world map if you haven't completed them.
