Left out one clue (discovered when I started recalculating the tally); it'll be folded into the other clues if not found first:

63. From a TV show; based on comics; 10s; Black Lightning; nickname is currency of some sort

A lot of the remaining characters don't warrant another round of character-specific clues so will start a Hangman round. Unlike the Arrowverse rounds, I generally haven't bothered with real names for characters using aliases. To avoid making it too easy to match with the tally, I'm not adding the source to the Hangman aspect. At this stage I'm not yet adding letters, just showing the number of characters

239 Stefano Galante, Birds of Prey movie

I think you need to check some of the clues, as he's neither an original character nor from a TV show.

63 Frank "2-Bits" Tanner, Black Lightning

117 Lucy Ricardo as Superman, I Love Lucy

166 has been identified. 

103 Linda Montoya, Lois and Clark

89 Dr. McIntyre, Smallville

Apologies if a few of the source clues are off. Because there are usually a lot of characters left when I start these, I sometimes make errors copying and pasting. I'll take a look at the remaining characters. While I tried to prune them out, some previously removed clues may have come back because the Hangman round was originally going to resume last week. But then more guesses happened, so I put it off until another lull, necessitating removing characters found in the meantime.

Everyone correct; list updated.

In the case of Lucy, I wanted to highlight the episode where she meets Superman, but it's not clear if the Superman she encounters is the same one from Adventures of Superman (thus already in the 2020 collages), a close counterpart, or a counterpart of George Reeves rather than Superman (likely back then they wouldn't have split hairs that way). But at least by showing Lucy in costume I could at least allude to that episode.
