If you saw the new Superman, chances are you caught that brief glimpse of the mural in the Hall of Justice honoring the 300 years of metahuman lore James Gunn’s new DC is founded on. While there’s been speculation about which characters were fleetingly depicted, Gunn has since shared the mural online for fans to pore over themselves and guess accordingly the who’s who of this new DCU.
As these are, indeed, some deep-cut characters, we’ve analyzed the data and are at least 75% sure we’ve identified each hero of yesteryear officially canonized. Here’s our guesses and guide from left to right.

Mural 1
Sister Symmetry/Madame Xanadu
If we haven’t missed our guess, the first hero to exist in the DCU is Sister Symmetry, a relatively new creation introduced in the pages of Justice League Dark back in 2019. Technically an enchanted cloak with a revolving door of alternating hosts who wear it, the entity possessed the Tarot card-reading soothsayer, Madame Xanadu, which, as you can see in the mural above, the character is haloed by. Not a bad start for this brave new world with such people in it…
Silent Knight
Next up is Silent Knight, the occasional time-traveling medieval hero from sixth-century Britain introduced in the very first issue of The Brave and the Bold in 1955. Created by Robert Kanigher, the character is secretly Brian Kent, the son of a feudal lord killed in a jousting tournament. While the character has had adventures with King Arthur, Morgaine Le Fey, and the Knights of the Round Table, his namesake derives from his refusal to speak while wearing his red and white suit of armor so as not to betray his secret identity to anyone—even his lady love, Celia.
Exoristos
An Amazon exiled from Themyscira for her poor behavior, Exoristos traveled the world for several years, becoming something of a legend for her numerous adventures—including one notable chapter in which she was turned into a vampire by Cain, the first murderer of the Bible, who also hosts his own horror anthology published by DC Comics. Happily, she would eventually find herself back in her fellow Amazons’ good graces after participating in the American Revolution. Good for her!
