Avengers - The Trial of Yellowjacket (2012)

Collects Avengers (1963) #212-230.
THE END OF AN ERA! They say that pride comes before the fall, and this tumultuous tome is proof of that! When longstanding and founding member Hank Pym -- in his guise as Yellowjacket -- demonstrates reckless behavior in battle, his fellow members schedule a formal court-martial hearing in order to determine the fate of their emotionally conflicted comrade. Will Yellowjacket triumph over his inner demons -- or crumble under the pressure of being an Avenger?
