What is a meta hero?

Excuse me, could you please elaborate on the concept of a Meta hero? I'm somewhat familiar with the term in the context of gaming and storytelling, but I'm curious to know how it might be applied or interpreted in the realms of cryptocurrency and finance. Is it a newfangled term that's gaining traction in the industry, or is it a more nuanced concept that's been around for a while? I'm intrigued to learn more about how it might relate to the ever-evolving landscape of digital assets and investments.
