Dial H for Homo Neanderthalensis

H-E-R-O #11 doesn't tell us where the H Dial came from, but it does presumably recount the story of its first human user, a Neanderthal from 50,000 BC, responsible for a number of archaeological enigmas, like prehistoric animals with their heads punched in, a cave full of strange drawings UNDER METROPOLIS, and though no one's found it yet, the man's remains... on the Moon!

The Dial just fell from the sky during a snow storm in what is now Germany, no explanation given. And before he leaves Earth, the caveman throws the Dial away, its journey unknown until it's picked up in the 2003...

Case 74: H-E-R-O #11
Dial Holder: An unnamed Neanderthal, or is his name Oot?
Dial Type: Push-button Dial
Dialing: This Dial either exists since the dawn of man, or has time traveled to that point. It is not known if it predates the other Dials we've seen. The Roman letters H-E-R-O still feature even if the alphabet hasn't been invented. (Look for this mystery to be resolved by the end of this series.) Heroic identities are "of their time", so the superhuman caveman still wears skins and furs, not spandex. There is no time limit on the heroic identity assumed; once this caveman becomes a superhero, he keeps that identity until his death from old age (the identity shows aging normally).

Name: None given as this is a preverbal culture, but they keep saying Oot around him, which I've chosen to keep as his superhero name
Costume: A dark gray skin tunic, boots and bracelets, with a tan kilt and undersleeves, a rope belt wound around the waist several times, and a bear skin acting as a heavy cape, the animals front paws strapped around the shoulders. Oot is a tall, attractive, young man unlike his stumpier, under appreciated and bearded original identity.
Powers: Super-strength and invulnerability and flight. He is ultimately able to fly to the Moon and draw the Earth in the dust from there before dying of old age, so he can survive the vacuum of space, but ages normally. Oot also has mental capacities far beyond those of his people, producing cave art with perspective, portraiture, etc.
Sighted: "50,000 years go" in various parts of the world, meeting many primitive tribes of the day, creating complex cave art in North America and finally going off to die on the Moon.
Possibilities: Has no one ever met Oot? Not even Batman when he was sent back in Final Crisis? Has he ever fought Vandal Savage, or palled around with the Immortal Man? What about Anthro the First Boy? I'm a big fan of caveman stories, so I would totally be up for reading (or writing) this thing!
Integration Quotient: 100% (this barely charted territory is wide open!)
