Batman/Grendel Vol 2 #2

"Devil's Dance!"

Grendel-Prime is out of place and out of time. He came to Gotham to retrieve the essence of Grendel -- the skull of Hunter Rose. Now that he has the unholy relic, he must find his way out of Gotham before Batman catches up to him. Plenty of criminals come into his city, but they don't leave until the Dark Knight has delivered justice.
