[Dc Comics] Does the general populace know about Martian Manhunter? How's he perceived, what do they think of him?

What with being an ali**e**n and all. I mean sure Supes is also an alien, but at least he looks human.

Do they know what his power s**e**t consists of? Specifically his shape-shifting? Which personally would scare me.

Martian Manhunter actually has many secret identities. He's been here since before Superman landed, and he's a world traveler. He spent, and continues to spend, a lot of time battling injustice in countries where the Justice League and other high-profile heroes seldom go.

People tend to accept him, because he uses his telepathic and shapeshifting abilities to choose a form the locals trust. In the US, he often goes by John Jones, detective. But if he needed the trust of someone with no reason to open up to Det. Jones, he could just as easily be an illegal immigrant, little old lady, scientist, underpants-wearing no-powers street vigilante, or your favorite family member.

His public image is an odd one. Ordinary people know him as a polite heavy hitter who fights major threats or catches criminals — the green, caped muscle-man. They think of him as a different, more shy Superman. But the truly horrifying extent of his powers isn't widely known to humans outside of antiterror/espionage circles.
