38. Superman vs. Mongul
It’s Superman’s birthday and Batman, Robin and Wonder Woman are going to visit Supes at his Fortress of Solitude to give him some presents. However, the villainous Mongul has already beaten them to the punch by giving Superman the Black Lotus, a flower that attaches to people and forces them to live their happiest fantasy.
Now, Superman is able to fight the Lotus a little bit, and that is why his dreams of an unexploded Krypton are filled with not-so-happy memories, specifically that he is an ineffectual bureaucrat in this life.
Eventually, the Lotus is taken off of Superman, and boy, is he mad at Mongul!
Writer Alan Moore and artist Dave Gibbons (these two would later do some comic about a smiley face that some people think is okay) handle the fight beautifully, particularly Superman’s rage.
That “Burn” line is perhaps the most badass thing Superman has ever done.
