In Batwoman S01E09 aka Crisis on Infinite Earths: Part Two, we see that Superman Return version of Clark had a big loss in a gas attack (supposedly by Joker):

and we do see causality name few times skimmer over, I got one such screenshot:

I can figure out:

• Lois Lane

• Perry White

• Jimmy Olsen

• Ron Troupe

Is there any other prominient DC comics character from the casuality list?
