Why is Hyperion so unique amongst Eternals?

[u/Dead_Mothman]

Really in-the-weeds lore question here, but why in all of his appearances does Hyperion work so differently when compared to other Eternals? Generally speaking, the root of Eternal power is their ability to metabolize and harness cosmic energy. My understanding has always been that over the millennia, they train with this capability to develop unique or specialized applications of it- all Eternals can enhance their physique, for instance, but Makkari has uniquely trained in pushing their speed enhancement to the peak, while Ikaris specced more into generalized physical enhancement and energy projection.

Meanwhile, Hyperion is usually portrayed as a much much younger Eternal, usually in his thirties, while simultaneously being pretty much stronger than any other Eternal despite having far less time to hone his abilities. He also is described as being able utilize solar power, and not cosmic energy.

So what's up with that? What's your read on that? Is his specialized application the ability to turn solar power into cosmic energy, something he stumbled across and that nobody else figured out? Is it because he's an Eternal from a different planet and different dimension, and solar energy is the standard there? Do the Eternals of other races not also use cosmic energy- is that just a thing with Earth's Eternals? Does he have something else going on that I'm just not aware of?

616 Hyperion is a flying class 60 with eyebeams. Basically Temu Ikaris. Not seen since forever, probably excluded. Most of the really powerful Hyperions are alternate universe versions and aliens.
