Someone showed me this image:

The Periodic Table of Fictional Elements

In particular, they noted the comic book element redstone, Rs. the format states it is created by HA.

I did a bit of searching, checking Wikipedia, and I'm pretty stumped by what this element called redstone is or where it is from. Of course I know redstone from Minecraft, but this is apparently distinct, since it's in the comic book section.

Who or what is HA, and what is this version of redstone?

    @shanu At the risk of flooding the site with "what fictional element is this" questions, you could always ask a separate question about what "Clown" is.

    @F1Krazy Chances are it might be marked as dupe of this one, since I mentioned in the answer below how to learn more about every elements in the picture. But yeah, I agree, I almost answered in the comment until I saw yours.

According to this website, there used to be an interactive version of that fictional periodic table:


However, that link is no longer functional because the site died. But we can access it through the wayback machine. The page is blank, but upon checking its source code, we can download the following Flash content, which is the interactive periodic table: periodiekklein.swf.

By using a software to run the Flash content, we can see the following:

An interactive version of the fictional periodic table, which allows us to get more information by moving the mouse over a square.

Name: Red Stone
Source: Fullmetal Alchemist - Hiromu Arakawa
Specifications: Reddish stone. Ampifies the transmutation power of alchemists. Made with Red Water, a high-toxic liquid.

The Red Stone is also called the Philosopher's Stone in the manga Fullmetal Alchemist; although in this particular case, since Red Water is mentioned, it is most likely a reference to another kind of Red Stone from the 2003 anime, which is distinct from the Philosopher's Stone. HA is the author Hiromu Arakawa.

If you want to learn more about the other elements, you can download the file and run it either with a standalone Flash Player, or any browser based Flash Player (e.g. Ruffle for example).

    For what it's worth, I initially tried to find any comic book publisher whose name might be HA. In the end, I pasted the question's picture into Google image, and I luckily stumbled upon the website that mentioned the interactive version among many other results.

    The Red Stone mentioned in the table is a 2003 anime version (because it mentions Red Water), and in there it is another amplifier distinct from Philosopher's Stone. Jan 28, 2023 at 9:04

    Note that the 2003 anime diverges significantly from the manga which HA wrote. It is a bit of a stretch to attribute Red Stone to her, since it is not actually present in the material that she wrote. As a rule of thumb, Fullmetal Alchemist: Brotherhood (2008) is the more faithful adaptation, so if something is present in the 2003 anime but absent from Brotherhood, HA probably didn't create it.
