"What could cause Nash more grief than losing a daughter figure?" Oh, I dunno, maybe being Pariah and being forced to watch the annihilation of the Multiverse while knowing it's all his fault? Sheesh, I thought
The Flash was the one show that really
was exploring the aftermath of Crisis, and now even they're ignoring it. Well, the "Crisis on Infinite Wells" being in Nash's head was addressed, but Pariah is completely forgotten.
I guess when Thawne said "See you next Crisis," it wasn't so much about being involved in the Crisis as managing to exploit its aftermath. Perhaps being Pariah was the reason Nash drew all the other Wellseseses into his head, and Thawne spent enough years with his DNA altered to match Wells on a genetic level that he was able to piggyback on that. Hey, maybe that's
why he changed his appearance back to Wells! In
Crisis on Earth-X, it seemed like an arbitrary excuse to use Tom Cavanagh in the role instead of adding Matt Letscher to the already huge cast, but now we see a possible reason for it, if he somehow knew this was coming.
The Sunshine character has been touted in the press releases as the Arrowverse's first fully original supervillain with no basis in the comics (quite a change from the old days of superhero TV when original villains were the norm), but is that really true? Have we never before had a supervillain that had no counterpart or namesake in the comics? Certainly there have been antagonists that fit the bill, like various of the criminals-of-the-week in
Arrow, or Mallus on
Legends. But have all the costumed/powered/nicknamed supervillains really been comics-based without exception?
Anyway, they seemed to make a big deal out of giving Sunshine an impressive debut, and I'd say it was fairly effective. Plus they've established that Black Hole's pet villains are all, ironically, light-based -- the new Dr. Light, Ultraviolet, and now Sunshine. I wonder who else they might use. Looking over the DC Database, I see that other
photokinetic villains include a one-shot Milestone character called Laserjet (the last villain in the original
Static series), a couple of Legion of Super Heroes villains called Lazon and Quanto, a Charlton character named Doctor Spectro, an Appellaxian alien called Glass-Man, a recent Batman villain called Gnomon (though I doubt we'd see him on
The Flash since he's the father of a Batman-adjacent character who might show up on
Batwoman sometime), an Atom villain called Strobe, and others. It's a pretty common power, it seems, so Black Hole could have a pretty sizeable meta team on its side.
