The Mysterious Moonman

High above the city, from behind a dark drifting cloud the bright moon, magicianlike, appeared while, far below, in one of its myriad deserted alleyways the equally mysterious, black and silver clad superhero, Moonman materialised out of the thin night air.
Noticing the luminous glow of Moonmans suit, one of the muggers who had been holding an old man pinned against the alley wall turned and pointed his switch blade towards him.
"Get out of here before I cut you", he said.
The lunar powered crime fighter made no reply but, extending his right arm towards the mugger, used his gravitational ability to pull the handle of the switchblade from the criminals hand into his own.
Scowling the mugger ran towards him, his fists raised but then, using his remarkable phasing ability, just like his shining namesake, Moonman half disappeared, becoming less than a slender crescent of himself and, instead of colliding with him, the mugger ran through him and smack into the alley wall behind knocking himself unconcious.
Seeing his friend out cold, the other mugger started to run towards the entrance of the alley but Moonman wasn't about to let him escape with the old mans money and, extending his arm, the superhero turned his gravitational powers up full latching onto the fleeing criminal and dragging him back towards him before grabbing him from behind and drawing his silver, crescent shaped sickle from his belt he held it to the criminals throat.
"The old mans money and possessions if you please", he said in a sort of throaty whisper.
The mugger reached into his jacket pocket and took out a wallet and wristwatch.
"Please don't hurt me", he asked Moonman, handing the watch and wallet back to the old man.
The old man checked his wallet.
"Its all there", he told the hero.
"Alright", said Moonman to the mugger, "I'll let you go but everytime your out at night and you see the moon in the sky, just remember I'll be watching you".
But then, hanging his sickle back on his belt, he let the mugger go and the terrified man tore out of the alleyway.
"That was amazing", said the old man, "You really showed those young punks".
But then, suddenly, horrified the old man heard the sound of gunshots and saw Moonman fall to the ground.
The other mugger, the one that had been knocked out earlier, had regained consciousness and had pulled out the revolver he kept for emmergencies and shot the superhero in the back.
"Damn you", shouted the old man, waving his walking stick at the mugger, "You killed a hero".
Putting away his revolver the mugger laughed.
"Guess he wasn't so tough after all", he said.
Just then however, the old man noticed something odd about the body of the superhero lying on the ground at his feet; it was starting to change.
As the man watched, to his amazement, the black of Moonmans costume started to become bright blue and the silver became gold and most amazing of all the bullet wounds and the holes in the back of Moonmans costume started to heal up.
Then, suddenly, getting up off the ground, another superhero stood where Moonman had fallen.
"Who the hell are you?", asked the Mugger.
The new hero extended his right arm towards the mugger and fired a blast of solar energy towards him knocking him off of his feet.
"Solarman", he said.
"Wow", said the old man, "That was amazing. You're two superheros in one".
"Well", said Solarman with a smile of gold, "When the Moon goes down, the Sun comes up".
