Rainbow Energy

Rainbow Energy is not a Pokémon but a special Energy card that has been a staple in the Pokémon Trading Card Game since its introduction. It represents a universal source of power, capable of fulfilling any Energy requirement for a Pokémon's attacks. Unlike basic Energy cards which provide one specific type, Rainbow Energy's unique property allows it to provide any color of Energy, making it incredibly versatile for decks that utilize Pokémon with diverse Energy costs or multiple types. While it doesn't have a Pokédex entry, its function in the TCG is critical for many strategies, particularly those involving multi-type Pokémon or complex attack costs. Its concept of universal energy is often reflected in various forms across different TCG eras, underscoring its enduring utility and strategic depth.
