@MidnightRider Look up the graphic novel "Negative Space." Minus the Trump part, that's basically the plot.
@TheEyeOfBalor Refresh my memory. I probably read it but it's been 40+ years
@artildawn
Can't remember the exact publication date nor specific edition number, but there was an alien named ZZZax which fed off fear. The JLA killed it by creating a nightmare in Superman's unconscious, which was so powerful it overwhelmed ZZZax and killed it. It came out between 1974 and 1977, I believe. I owned it back in the day!
@TheEyeOfBalor wait...Zzzax is Marvel's. A quick search for aliens feeding on fear for DC gave me Nekron. That was in 76, which I was reading at that time, but the characters doesn't look familiar at all.
@artildawn
Yes, that's the one! He fought the JLA and was thrown down, literally, into the Eiffel Tower, if memory serves.
@artildawn @MidnightRider
There was also a Justice League comic book back in the mid-'70s with the same premise.
That said, it's certainly applicable today.
