A Black Dragon is the one hundredth and sixty-sixth chapter of Hiro Mashima's Fairy Tail.

Full Summary
The chapter starts with a flying Microphone announcing that Magnolia Town is changing to Gildarts' mode. Back at the guild, Lucy is shocked to learn of the 100-year job, and asks Mirajane what Gildart's mode is. Mirajane tells her to go outside to see. Lucy goes outside and is surprised to see that Magnolia has split to form a path towards Fairy Tail. Mirajane explains that Gildarts' magic allows him to smash anything he touches, and he sometimes destroys houses when in town. Everyone is excited when they saw Gildarts walking towards them. As soon as Gildarts walked through the door, Natsu challenges him to a fight. Gildarts ignores him and asks Mirajane were Fairy Tail is. As soon as Mirajane explains where they are and who she is, Natsu charges towards Gildarts. Gildarts greeted him and tosses him to the ceiling ending the "fight". Gildarts is catching up with everyone when Makarov asks him about his mission. Gildarts explains that he failed much to everyone's surprise. Makarov is happy that he was able to come back. Gildarts then leaves through the wall after saying good bye and telling Natsu to go to his house. Natsu and Happy is walking towards Gildart's house. When they arrived, the first thing Gildarts asks was about Natsu and Lisanna's relationship. Natsu explains that Lisanna has died two years ago and turns to leave. Gildarts stops him by saying that he met a dragon during his mission. Gildarts says that it was a Black Dragon not the red one which is Igneel. Natsu tries to leave again saying that he will ask the dragon about Igneel's whereabouts. Gildarts stops him again and shows the injuries that he got from the dragon, saying that humans can't beat the dragon. Natsu replies that that was the reason why there are Dragon Slayers. Natsu then leaves. Gildarts tells Happy to support Natsu saying that a human can't beat a dragon, but maybe a dragon can. Meanwhile at Fairy Tail, Makarov is thinking about his three Dragon Slayers (Natsu, Wendy and Gajeel) and fate making its move. Back to Natsu, Natsu is running down a hill, trips and falls to the river. The episode ends with a picture of a young Natsu and Igneel and the real Natsu thinking about how his "dad" was doing...
