did hawkman inspire he-man?

Hawkman is an old superhero from the Forties.

Here he is in DC's first Hawkman in the Sixties.

I couldn't help noticing old Hawk's emblem.

It reminded me of The Thundercats from the Eighties.

Here's Hawkman's emblem.

Here's Thundercats'.

And what about that X-belt the bare-chested Hawkman wears?

I reckon He-Man swiped that idea straight of his super toned back!

What do you think readers?

Coincidence?
