Reminds of when Barney on How I Met Your Mother was trying to remember the holy grail of cups

Childhood trauma

Per Glen Weldon in his book Superman: The Unauthorized Biography, kryptonite representing the destructive force of nostalgia and survivor’s guilt, reminding us that clinging to the past can undermine the present.

Siegel and Shuster had created the Man of Steel as the ultimate immigrant, the personification of the promise America represented to them. His abilities are metaphors for limitless potential and opportunity, for new horizons stretching out before us: the American Way.
It seems fitting, then, that the only thing capable of harming him would be a reminder of the Old World he left behind, a past that is irrevocably gone. Only the past—our past—can hurt us.
To this day, kryptonite functions in the Superman mythos as the physical manifestation of both survivor’s guilt and a particularly toxic kind of nostalgia, a reminder that when we dwell on what we’ve lost, we can kill what we have.

Superman's Kryptonite is that he can never, ever be fed after midnight!

Superman's kryptonite is the fact that he is popular and everyone thinks the character would make great media, but the character is way too overpowered to write good plots for.

Oh, that and actual Kyrptonite.

Zack Snyder.

🤨

Literally kryptonite. Particularly the green kind.

he needs a telephone booth to change?

Obviously loss of glasses, making him recognizable in civilian life.

Dats a shitpost alright

I’m like 99% sure that he is afraid of bald people. Whenever the reoccurring token bald guy shows up he gets really scared. He could just be afraid of robots, I remember he was afraid of batman’s robots too, I don't believe batman is bald, but I’ve never seen batman without his suit. Superman has X-ray vision though, and I'm not sure he can turn that off so maybe he is afraid of batman because he is bald and not because he is afraid of robots.

Robots and bald people, final answer.

Superman's kryptonite is interesting writing

I'm pretty sure it's magic.

He's super pee-shy, can we use that against him?

True heterosexual love between a biological man and a biological woman. It's why he never hooks up with Lois Lane and keeps sneaking peeks at Jimmy's junk at the gym.

Solid JJ the only real answer to this shit post

Superman's kryptonite is still unkown, unfortunately.
Scientists have speculated that understanding the physiology of Subman (Superman's greatest threat) may help us find it, but so far polite requests for non-invasive experiments have been declined and we cannot, in good conscience, forcefully subject him to them.

Kryptonite....

Trying to recreate that reddit post, huh?

Preparation time?

Horses.

A mixture of: 15.08% plutonium, 18.06% tantalum, 27.71% xenon, 24.02% promethium, 10.62% dialium, 3.94% mercury, 0.57% an unknown element not found on the known periodic table. You could use tar instead.
