time to stop the supervillains who raised them from altering history. When trying to change Batman's history back, Batman breaks down and shoots Joe Chill – the killer of Thomas Wayne and Martha Wayne. The Legion then team up with Ra's al Ghul to take over the world. Superman and Batman restore history, but the murders they committed haunt them. Issue #19 (illustrated by Ian Churchill) is a stand-alone backdoor pilot story for the Supergirl series. The issue was later reprinted as Supergirl #0. In "With a Vengeance!" (issues #20–25, illustrated by Ed McGuiness), Mister Mxyzptlk battles the Joker, who has tricked Bat-Mite out of his powers, using other characters as their pawns. Superman and Batman fight a team of superheroes from an alternate universe called the Maximums (a pastiche of Marvel Comics' Avengers series, more specifically their incarnations from the Ultimate universe, the Ultimates). Keeping the bargain he made in "Absolute Power", Superman frees Darkseid from the Source Wall. Double-crossed, Superman becomes stuck in the wall himself. Bizarro and multiple Supergirls rescue him. Everyone so far and many more other duplicates fight in an arena before Bat-Mite escapes. The two imps tie up all loose ends with their cosmic powers. Additionally, Superman, Batman and the Toyman discover that Captain Atom is alive. "Who Would Win?" (issue #78) Sam Loeb Before he finished writing Superman/Batman #26, Jeph Loeb's son, Sam, died on June 17, 2005, at the age of 17, after a three-year battle with cancer. The issue was supposed to be Sam's DC writing debut and was to be illustrated by Pat Lee. Jeph, along with 25 other comic book professionals and artists who had known Sam, worked on the issue, scripting or penciling individual pages. Marvel Comics allowed John Cassaday and Joss Whedon to work on the issue, despite their exclusive contracts. All 26 contributors donated their fees and royalties for the issue to the Sam Loeb College Scholarship Fund. In "The Boys Are Back in Town" (issue #26), Superman and Batman send Superboy and Robin to visit the Toyman in Japan because he has not been heard from in a while. The issue was released shortly after Superboy's death in Infinite Crisis #6, and Robin's eulogy of Superboy serves as both a framing sequence and as a meditation on the author's passing. The 26 contributors to the issue: "Sam's Story", a back-up story written by Jeph Loeb
