Marvel Adventures The Avengers #1

In "The Replacements," the Avengers are abruptly replaced by the ultratechnological ULTRON 700 Global Defense System—a seemingly flawless, world-wide computer program designed to protect humanity. But when its first threat assessment identifies humans as the primary danger, the system's logic leads to a chilling, unexpected conclusion. Written by Jeff Parker and illustrated by Manuel Garcia with inks by Scott Koblish, colors by Val Staples, and letters by Dave Sharpe, this 2006 Marvel Adventures tale features a cover by Aaron Lopresti.
