Pre-Crisis
Bat-Mite regularly appeared in Batman, Detective Comics, and World's Finest Comics for five years. Bat-Mite and Mr. Mxyzptlk teamed up four times in the pages of World's Finest Comics to antagonize Superman and Batman.[5] In 1964, however, when the Batman titles were revamped under new editor Julius Schwartz, Bat-Mite vanished along with other members of the Batman extended family, such as Batwoman, Bat-Girl, and Ace the Bat-Hound.
After this, only three more Bat-Mite stories were published in the pre-Crisis DC Universe: two more Bat-Mite/Mxyzptlk team ups in World's Finest Comics #152 (August 1965) and #169 (September 1967) (which were not edited by Schwartz, but by Mort Weisinger),[6] and "Bat-Mite's New York Adventure" from Detective Comics #482 (February–March 1979), in which the imp visits the DC Comics offices and insists that he be given his own feature in a Batman comic. This story featured protestors with picket signs shouting "We want Bat-Mite!" outside the Tishman Building (where DC's editorial offices were located at the time), and was accompanied by an editorial comment that this story was published to acknowledge the real-life requests of fans for this character's revival.
Post-Crisis
After the continuity-changing 1985 limited series Crisis on Infinite Earths was published, Bat-Mite was mostly removed from the Batman comics canon.[7] Bat-Mite made an appearance in Batman: Legends of the Dark Knight #38, although he may have been the hallucination of a drug-addled criminal named Bob Overdog. This comic states that Bat-Mite is one of the many admirers of superheroes from another dimension. This version of Bat-Mite later returned in Batman: Mitefall — A Legends of the Dark Mite Special, a one-shot book which was both part of, and a parody of, the Batman storyline Knightfall (with Overdog briefly in the Jean-Paul Valley role). In #6 of the 1999 Batman and Superman: World's Finest miniseries, Mr. Mxyzptlk encounters Bat-Mite, shortly after being mistaken for him by Overdog. While in this story, the post-Crisis Bat-Mite encounters Batman for the first time, Superman and Batman subsequently concluded that Mxyzptlk had created him, inspired by Overdog's ravings.
Bat-Mite also appeared in the 2000 one-shot Elseworlds comic special World's Funnest, in which he battles Mr. Mxyzptlk, destroying the Pre-Crisis multiverse and the post-Crisis DC Universe, as well as the Elseworlds of Kingdom Come, Batman: The Dark Knight Returns, and the DC Animated Universe.[8]
The first post-Infinite Crisis appearance of Bat-Mite was in Batman #672, written by Grant Morrison.[9] Batman is confronted with Bat-Mite (or "Might") after being shot in the chest and suffering a heart attack. Might, who bears a green insectoid creature on his back, claims to have come from "Space B at the Fivefold Expansion of Zrfff".[10]
After Batman transforms himself into "the Batman of Zur-En-Arrh", Might counsels Zur-En-Arrh, a 'back-up' personality manufactured by Bruce himself to keep Batman able to fight in case he was mindwiped, or driven to insanity. Batman #680 reveals that Might is a product of Batman's imagination, representing the last vestiges of his rational mind.[11]
Bat-Mite appeared in a self-titled six-issue miniseries which lasted from June to November 2015.[12]
Bat-Mite appears in the four-part story "Impossible" in World's Finest #26 through #29, June through September 2024. The story also features Superman, Batman, Robin, Jimmy Olsen and Mr. Mxyzptlk.
