Danny frantically searched as he flew through Metropolis, Clark was in trouble and he needed to get there quick! It didn't take long to find him, Clark in his suit collapsed on a rooftop, arms shaking as he tried to push himself back up. An empty power suit stood nearby, between it and Clark stood Lex Luthor holding a fist sized lump of glowing green crystal. Ugh! This was why it had to be Danny and not any of the others.
Danny's red boots crunched on the crusty rooftop as he landed next to Clark, "Dad!"
"Nova," Clark gasped, his arms giving out.
"Well, well, well, if it isn't Supernova," Luthor said in a voice that sounded too much like Vlad. "Careful there, wouldn't want to get close to this." He held the ominous crystal a little higher, as if Danny hadn't seen it before even landing.
Internally Danny cheered, he knew exactly what he was going to do. Outwardly he ducked his head down, taking off his cape and laying it over Clark while he got his shit together. Then he stood and made uncomfortable eye contact with Luthor, keeping his face as blank as humanly possible while he walked towards the bald man.
"W-what?! What are you-" Luthor's feet stuttered as he took a few confused steps back, not nearly quick enough to get back into his power suit before Danny was standing uncomfortably close to him.
"There's something you don't know about me, Luthor," Danny said darkly.
"What?" Luthor asked, clearly having trouble processing what was going on.
Danny leaned forward, opened his mouth wide, then took a bite out of the chunk of kryptonite. He grinned far too wide and let his eyes flash green as he looked up at Luthor, "I'm adopted."
"You're…" Luthor stared blankly at the half eaten crystal in his hand.
Danny straightened and plucked the whole rock right out of Luthor's limp fingers, then unhinged his jaw so he could toss the whole thing in. It wasn't easy or fun to do that in his human form, but it was worth it to see Luthor's brain shut down in real time.
"Mmmm…" Danny said as he chewed through what was essentially ghost rock candy. "Tangy, juicy, fruity… sour apple? Not my favorite flavor, but still good."
"You're… adopted…" Luthor said blankly.
"Yup," Danny popped the P, hoping to keep Luthor distracted while Clark recovered. "There's a reason I don't wear the crest of the House of El." He pointed to the yellow starburst on the chest of his navy blue suit. "And this isn't even a recently discovered survivor of Krypton coming to Earth type deal, I'm not Kryptonian."
"Then what are you?" Luthor sounded genuinely curious.
Danny grinned even wider, showing off a row of razor sharp fangs, "Human, of course."
"Human," Luthor said with a snort, clearly not believing that.
"Born and raised here on Earth, human parents, human friends, red blooded human through and through.
"You are not!"
"Oh Lexie, can I call you that? Oh Lexie," Danny floated up high enough to easily pat Luthor on his bald head, "any human can do this. It's not my fault you haven't unlocked your full potential yet."
"Supernova," Clark said warningly as he grabbed the back of Luthor's shirt and lifted him up, but the twinkle in his eye told Danny he wasn't in any real trouble.
"Feeling better, Dad?"
"Much. Now to just take care of him."
"Put me down this instant!" Luthor demanded.
"Dad, can I keep the robot? I wanna see if it has any more rock candy hidden in it." And take it apart for parts, it would be so much fun to tinker with.
Clark made a show of thinking it over. "Sure, bring it to the Fortress."
"Yes!" Danny did an aerial fist pump before zooming over to his new pet project.
