Some familiar faces are returning to the world of Arkham.

Coming ahead of Batman: Arkham Knights' latest trailer release on Monday, it has been revealed that Nightwing, Robin, Catwoman, and Azrael are all returning as characters for the final Batman: Arkham installment. As part of their marketing for the game, developer Rocksteady hid codes for each character within the trailer, that when entered on the official Arkham Knight website, revealed each character and their biography.

But, the Internet being what it is, beat Rocksteady's trailer to the punch and deduced the codes before they could even appear in the trailer, which doesn't land until April 27.

When one enter the code "flying graysons," the character bio and a GIF for Nightwing appears.

When you enter the code "bostaff", the character bio and GIF for Robin appears.

When you enter the code "parkrow," the character bio and GIF for Catwoman appears.

And finally, when you enter the code "suit of sorrows," the character bio and GIF for Azrael appears.

Clever, Rocksteady. But apparently, not clever enough.

You can read all the character bios in the gallery below. But what say you, readers? Excited by the reveals? What other characters from the Arkham-Verse would you like to see return? Sound off in the comments below.

Batman: Arkham Knight hits PS4, X-Box One, and PC on June 23.
