Fan Casting Brainiac in Batman: Into the Millerverse

Brainiac is an alien super computer who allied with Lex Luthor against Superman. Working with Lex Luthor in running the United States of America, Brainiac aided in blackmailing Wonder Woman, Superman, and Captain Marvel by holding the bottled city of Kandor hostage and in check via a Red Sun lamp. As Batman's resistance continued to make a name for themselves, Brainiac enacted a plan to disgrace the usefulness of superheroes by destroying a city while ordering Superman to run away. When the hero refused to fight nor run, Brainiac continued to destroy the city anyway, prompting Wonder Woman and Captain Marvel to fight Brainiac instead. Brainiac's body was then destroyed by Superman and Wonder Woman's daughter Lara, with their heat vision which decimated a large part of the city. With Lara's existence revealed, Brainiac once again threatened Kandor to lure her to him, with the goal of digitizing her, falling under his control. Due to planning by Batman, Lara secretly deployed the Atom into the miniature city, who destroyed the Brainiac probes within, freeing the Kandorians. With their combined might, the freed Kryptonians, Lara, and the Atom finally defeated Brainiac.
