Justice League Unlimited #21

Justice League Unlimited #21 was published in 2006 by DC Comics, serving as part of a tie-in series designed to expand upon the continuity of the popular animated television program of the same name. These comics were intended to provide younger readers and fans of the DC Animated Universe with supplemental stories that mirrored the aesthetic and tone of the Bruce Timm-led animation style, bridging the gap between television episodes.

The issue features work by writers such as Adam Beechen and artists who specialized in the clean, bold linework characteristic of the DCAU aesthetic. The series was designed to be accessible and episodic, maintaining the continuity established in the television show while allowing for character-focused narratives that did not always fit the constraints of a half-hour broadcast. It was received as a faithful extension of the animated medium, valued primarily for its role in maintaining the engagement of the show's established fan base.
