Chapter 217

A New Power and All For One is the two hundred seventeenth chapter of Kohei Horikoshi's My Hero Academia.

Synopsis
Around 7:00 PM at evening, Izuku Midoriya and Katsuki Bakugo Bakugo engage in a sparring match at Gym Gamma. Katsuki questions Izuku on why he hasn't activated his Blackwhip ability, in which the latter reveals that it apparently can't be unlocked as of now. All Might immediately tells the two to halt the match for the sake of discussing more about Izuku's current development. As the brief brawl stops, Katsuki points out that Izuku’s black tendrils only appear whenever he's put into mortal danger. All Might then expresses concern for his pupil, Izuku.
