Action Comics #853

In "3-2-1 Action! Part 2 The Signal," the lab monkey from the Kryptonite Man's creation escapes and reunites with his unstable creator, setting off a chain reaction at Rydertech's labs. With Jimmy now operating as the hero Mr. Action, he faces a dire challenge when both he and Superman are overpowered—only for a hidden signal to summon Krypto, the last of Krypton's dogs, in a moment that changes everything. Written by Kurt Busiek and illustrated by Brad Walker, with inks by John Livesay, colors by Pete Pantazis and Lee Loughridge, and letters by Jared K. Fletcher, this 2007 Action Comics issue features a cover by Brad Walker and John Livesay.
