Brainiac and Superman in “Knight Time”

I suspected that we might meet, Batman.

[as Batman] You got into Wayne's computers during his partnership with LexCorp.

Yes.

[as Batman] You saw that his company could built you a rocket, so you took control of Bruce Wayne and had him authorize the project.

You're every bit the detective that your followers on the Internet believe.

[as Batman] I also know how you work: collect a planet's knowledge, then destroy it. I can't allow you to leave.

What you allow does not concern me. While your deductive skills are impressive, you are still only human.
