Miscellaneous
- Brain made an appearance in issue #29 and a cameo in the Teen Titans Go! comic book series.
- Although he never appeared in Justice League himself, a version of the Brain from this continuity appeared in a comic story based on the series, where the League faked an elaborate 'auction' to lure all of their villains into one place. When the Brain realizes what is happening, he attempts to deduce which members of the auction are actually League members in disguise, but his deductions are thwarted by the assumption that Superman, Batman and Wonder Woman were not among the League members (being seemingly frozen in time by Chronos) and he only had to track down Flash, Green Lantern, Hawkgirl and Martian Manhunter, when in reality even Chronos's role was faked (Chronos being a disguised Batman) and the League managed to capture the villains.
