I'm assuming you ment "Again". in that case, he has appeared in the series 5 times. once in luffy's flashback story, once when Mihawk visited him to tell his of Luffy's bounty, once when Shanks was in communication with Rockstar over Whitebeard, and last time we saw him in person was when he boarded Whitebeard's ship to discuss Ace and Blackbeard. Shanks was also mentioned by a Vice Admiral that he has intercepted Kaidu from attacking Whitebeard and started a fight with him. Shank's most recent appearance has been in one of Ace's flashbacks. Ace went to visit Shanks to thank him for saving Luffy.
