Warning: spoilers for DC vs. Vampires #4 are ahead.
Ever since DC Comics. He has the Batcave, batarangs, Bat-Signal, Bat-Computer, and more. The list goes on and on as he continues to name tools and gadgets as they are by simply preceding them with the word "bat." This is out of control and Bruce needs to be stopped.
The naming convention really is not so bad as long as Batman sticks to his crime fighting arsenal. As a bat-themed hero, it actually makes sense for Batman's best gadgets to be named that way. However, he crosses the line in DC vs. Vampires #4, written by Matthew Rosenberg, James Tynion IV, and Otto Schmidt. After a brief tussle leaves both Batman and Green Arrow injured and bleeding, Batman instructs Arrow to "try and not get any more blood on the 'batfloor.'"
ittedly, this is a fun moment in a rather dark setting, but it is also just one moment out of several where Batman has given a ridiculous name to something. It's finally time to look back throughout the character's history and look at some of the things the Dark Knight has bat-named.
To start, there was once a time where Batman renamed himself to Bat-Baby. 1962's Batman #147 by Bill Finger, Sheldon Moldoff, Charles Paris, and Stan Starkman sees Batman hit with a scientist's de-aging ray, a popular trend in comics at the time. Despite reverting back to a child, he retains all his knowledge and combat prowess, and continues to fight crime on the streets of Gotham. This is the only issue in history to ever feature Bat-Baby, and it's probably for the best. It would have only been a matter of time before the Bat-Rattle was introduced.
Tools are one thing, but not even animals are safe from Batman's naming. When Bruce's family scattered across Gotham at the end of Detective Comics #1033 from Peter Tomasi, Brad Walker, Andrew Hennessy, Dave McCaig, and Rob Leigh, he packs up and gathers up his pets for a vigilante road trip. Among them is the famous Bat-Cow. To be fair, Bat-Cow was named by Damian Wayne after being saved from a slaughterhouse, but Batman went with it and highly approved of the creature. In addition, there is the Bat-Shark Repellant, which was first introduced in the 1966 film, Batman: The Movie. It made its official comics debut in the 2012 Legends of the Dark Knight series.
From the Batmobile, to Bat-Shark Repellent, to batfloor, Bruce Wayne has a fun and weird bat-naming obsession that's out of control. But honestly, what if he does it just because he can? Who's going to stop him? With that in mind, it's only a matter of bat-time before Batman bat-names another bat-thing.
