Hello, I'm an expert in comic book lore and superhero mythology. Let's dive into the fascinating world of Superman and his notorious weakness.

Kryptonite is a fictional mineral originating from Superman's home planet, Krypton. It's best known for its harmful effects on Superman when he is in the presence of Earth's atmosphere. The mineral comes in various forms, each with its own unique properties:


1. Green Kryptonite: The most common type, it weakens Superman, causing him to lose his powers and become as vulnerable as a human. Prolonged exposure can be fatal.

2. Red Kryptonite: This variant has unpredictable effects, often altering Superman's personality or causing physical mutations, but it doesn't weaken him in the same way as green Kryptonite.

3. Blue Kryptonite: Similar to red, blue Kryptonite has different effects on Superman, but it's less common in stories.

4. Gold Kryptonite: This rare type is known to remove a Kryptonian's powers permanently, making it particularly dangerous.
