This physical reliance is very importance to make stories more immersive, that's notably was my character/power mostly relies on tangible references mankind is very familiar with (absorption, memorization, replication, information, template, transformation, etc.), only the source reaching the most transcendent level possible, in order to ensure the ability's completeness beyond any reasonable doubt.

Supernatural versions of energy certainly permeate many exotic realities, quite a few even directly run on it. But there may as many where "energy" is simply absent, notably conceptual ones operating under completely different paradigms, where things may happen out of pure randomness, without any qantifiable factor directing their course

Eldritch realms may have their own version of energy, and merely follow twisted versions of our reality's pattern. But they may as well follow totally unrelated ones, or even none at all. Energy is a reliable reference to induce an immersive touch of realism to stories, but nothing can reasonably guaranty its rule in every single reality.

In short, the most crucial factor of a given reality may be completely irrelevant in another.

Which is why "omniverse" doesn't seem suited for a power so heavily reliant on real-life.
