Did Dirac's math hint at a shadowy twin of electrons?

Imagine you're playing a video game where you can create characters with special powers. Suddenly, you discover a character that can defeat another character of the same type but with opposite powers. It seems like a plot twist, but it's actually a real scientific discovery.

Dirac's math suggested there could be particles that are mirror images of electrons, with opposite charges, which we now call antimatter.

Example

In the game, if you have an electron character, Dirac's idea is like finding its antimatter twin, which can annihilate with it to release energy.

Remember this

Dirac's equation predicted antimatter's existence, showing that particles and their opposite charges are real, not just a game twist.
