Captain America #21
In "Soundquake," Captain America faces a crisis born from his own weapon: a fractured shield has unleashed a dangerous vibranium corruption spreading across the planet. With the threat growing, Klaw—last seen imprisoned in a vibranium cell—breaks free, setting the stage for a high-stakes confrontation. Written by Mark Waid and brought to life by Andy Kubert’s dynamic art, with inks by Jesse Delperdang, colors by Gregory Wright, and letters by Todd Klein, this 1999 issue delivers a tense, grounded thriller. The cover by Andy Kubert and Jesse Delperdang captures the urgency of the moment.
In "Soundquake," Captain America faces a terrifying new threat when his damaged shield begins spreading a dangerous vibranium corruption, putting the entire planet’s vibranium at risk. With Klaw—last seen imprisoned in a vibranium cell—now free and on the move, Steve Rogers must confront both the unraveling of his iconic symbol and a villain whose powers are perfectly tuned to exploit the crisis.
