Here's How The Umbrella Academy Cast Compares to the Dark Horse Comics

Known in the comics just as "Carmichael," the show introduced this talking goldfish character in Season 2, and gave him a first name: "AJ." Since The Handler is a new character created for the show, their relationship here is uncharted waters. It's interesting to see that The Handler and AJ, who's her boss, have a prickly relationship—to put it nicely.

In the comics, Carmichael is the leader of Temps Aeternalis, which is what fans of the show know as "The Commission." He's a intelligent goldfish, and in the comic source material he uses that intelligence to influence the timestream—though it's significantly less impactful in the show.
