Legend of the Bat Ninja!

"You know, if you wanted help with cleaning the basement you should've told me." An old man said helping his wife move a large chest upstairs.

"Please Hanzo, you know very well as I do that I'm more than capable of moving some stuff for a little cleaning." The old lady chuckled.

"I know Sayuri, but neither of us are getting any younger and soon we won't be around in this world anymore." Hanzo reminded that they're time will come any day in their old age.

"True, but at least we'll leave things to the next generations like Asuka and her friends." Sayuri smiled as they made their way to the living room and sat is down next to the couch.

"Now, let see what we should send away for donation?" Hanzo asked as he opens the chest.

"Better not be something dangerous or perverted, we don't want any more perverts like you in the world." Sayuri stated as she sits down.

"That's hurtful honey, I take things serious!" Hanzo defended himself.

"Like how you tried to train Asuka and Homura?" Sayuri reminded her husband of that day, Hanzo chuckles nervously.

Hanzo looks down at the many items he had stored in over the years, seeing some old ninja equipment he used in his ninja days.

See, Hanzo and Sayuri weren't just normal people in their younger days: they were ninja or shinobi whichever you like to call them and made themselves known as legends among the other shinobis with their great strength in battle and having kind souls for being Good Shinobis always willing to help others and completing missions and battling against Evil Shinobis too. But that's all in the past now and they're retired from battling though despite their old age they can still hold their own in fights to show the youngsters to never mess with their elders.

Hanzo then spotted something in pile and pulls out an old book with a bat symbol.

"My, my, I nearly forgotten about this." Hanzo said walking to the couch and sitting next to his wife.

"What's that you got there?" Sayuri asked.

"It's the book my mother and father used to read to me when I was a little child, the Legend of the Bat Ninja." Hanzo answered showing her the book.

"Oh, I remember that story it was a famous story that some Shinobis today heard about it." Sayuri smiled.

"Yes, the story of a ninja bearing the symbol of a bat that had to said to be the strongest shinobi in the world and there was even a whole clan of them. The Bat Ninja would always help lives from within the shadows and seek out evil in the name of vengeance with skills of every martial arts in the world and a great mind like two smartness detectives combined." Hanzo said flipping through the pages seeing the words just as he remembers.

"Whenever I hear the story, it always makes me feel that I could become strong too and taught me to never give up hope." Hanzo mentioned.

"Yes, though I am curious to known what happened to them legend says that in ancient Japan the country was in great danger that could destroy the world and the Bat Ninja stop it, but he suddenly disappeared without a trace along with the clan." Sayuri wondered what ever happen to the Bat Ninja.

"Well, I think that the world was saved the Bat Ninja wasn't need anymore and some say that when the world about to face that danger again, the Bat Ninja will come to aid us once again." Hanzo believed, stroking his bread.

"Well, it would be something special." Sayuri smiled, hoping that the legend is true then she looked at her watch seeing the time.

"Oh dear, I better get going." Sayuri said getting up from the couch and heading towards the door.

"Heading out?" Hanzo asked.

"Yep, I'm doing a special event for Asuka and her friends for training with the other shinobis from different schools." Sayuri smirked.

"Including the rogue shinobis?" Hanzo asked, Sayuri nodded.

"I see, well, have fun and tell Asuka to work hard in both mind and body." Hanzo said.

"Will do, goodbye dear." Sayuri said, giving her husband a quick kiss on the head before heading out.

"Knowing that woman, it'll probably be something both dangerous and fun." Hanzo chuckled, looking at the book for a moment before setting it down on the table.

What either of the elder shinobis know is that the legend about a ninja bearing a bat symbol is about to come true.

(DC Universe)

"Hey, come on you slowpokes, we have to get these stuffs in before the Boss goes crazy on us." Henchman 1 ordered as the other henchmen are moving some wooden boxes in the trunk.

"These things are heavier than they look." Henchman 5 struggled to hold it any longer until he managed to put it in.

"It's better than having to stand near the guy and he's only like, 16-years-old." Henchman 8 stated.

"I know, the guy gives me the creeps with that makeup of his. I'm starting to see why the Government banned the circuses in the world." Henchman 5 said.

"I'm pretty sure it was about the animal abuse." Henchman 3 corrected.

"Guys, can we just get this done? My mom is making pasta tonight and they're good, I want bath in her pasta sauce!" Henchman 7 with an Italian accent drooled a bit.

"Eww, way to make food sound so gross man." Henchman 3 grossed out.

Unknown the clown-mask wearing henchmen, a figure outside is watching them with his mask through the ceiling window.

"Seem they're getting some machine parts, what could they be up too?" The masked-boy asked himself.

He moves on the edge of the roof looking down to see two men guarding the door.

"So far, there are only two of them guarding both the front and back door. Better take them out first." He said.

The guards at the front door stand with guns in their hands given order to shot anything that comes here and hopefully not alert the police, then something quickly ran on the wall and knocked out one guard leaving the other shock before having his head slams to the brick wall knocking him out too. Next the two guards at the back door, one yawning getting bored with this job, probably regretting not finishing clown college, then suddenly a rope pulls the two guards together and are pulled away from the door as one almost screamed with a gun shot before replaced with silence.

"What was that?" Henchman 2 asked about the gunshot.

"It's probably just one of the boys spotted a rat and killed it from boredom." Henchman 4 said.

"Hey, you don't think… "he" is coming, right?" Henchman 5 asked worry.

"Who are you talking?" Henchman 7 confused of the question.

"I mean that new "Bat" hero I've been hearing about." Henchman 5 said.

"Seriously, just how many sidekicks does the Batman needs?" Henchman 9 winced, feeling like he got a headache.

"Doesn't matter, who knows about this warehouse believing to abandoned instead hold some very high-tech and the kid wants this stuff soon." Henchman 1 reminded the others of the job they have to do.

Henchman 2 and 4 went to pick up more boxes and suddenly felt something grabs their shoulders and pulls them into the corner screaming for an instant.

"What was that?" Henchman 7 asked.

"Don't know, let's go check it out." Henchman 8 said.

Both walk toward to where their buddies where at and found them unconscious and tied up together, as they are wondering what happened to them heard footsteps moving fast from above for a second and they found nothing.

"This is freaking me out, man." Henchman 7 panicked.

"Keep your cool, it's probably just the rats." Henchman 8 said.

"Squeak, squeak."

They jump quickly turning around and fire bullets at the unknown stranger and kept firing hoping they hit something, but that's has been proven nothing when the shadowy figure jumps from shelf and drop kick Henchman 8 down and punch Henchman 7 a few punches until he's out-cold.

"What's going on over there?" Henchman 1 shouted, but the only response he got was something sharp being thrown at the ceiling lights destroying lightbulbs making the place darker with only the moonlight from the sky.

Then before anyone know it, the henchmen are knocked down one by one as Henchman 1 started to panic and just fire his bullets in random directions hoping to kill the guy even if it means killing the others too, then he felt a punch across the face fired at where the fist came from. However, he couldn't tell if he actually hit something as he begun to sweat like a scared pig looking around trying to see who's the bastard messing with him.

"Where are you? Who are you?" Henchman 1 demanded.

"Right here."

Suddenly Henchman 1 felt his feet being pulled together and being dragged up to the ceiling window upside-down as he screams in fear and when he reaches the I-beams something pushes him higher clashing his body right through the window feeling cuts on his face. Now, being grabbed by the neck of his shirt and slam his face against the glass roof, Henchman 1 looks up to see the one doing all this tonight as the moonlight shines on the figure's appearance.

The figure seems to have some built in muscles though looks younger like nearly in his late-teen years, about 16-years-old to be exact, he's wearing a black mask that covers his entire head including the mouth with red-leans for the eyes and pointy ear-likes on the top. His whole clothing is colored black in the consist of traditional Japanese ninja uniform with a metal plate on the chest that is shape like a bat, two arm pads with three sharp spikes on each, and a katana in a black sheath on his back.

"I'm the Bat-Ninja." Bat-Ninja said, dragging the older man to the edge and holding him to the ground.

"What were you planning on doing with those techs?" Bat-Ninja asked.

"W-we were asked to bring them to out boss, he never told us why though." Henchman 1 answered, not wanting to be dropped.

"You sure you don't know why he wants them?" Bat-Ninja asked.

"Huh, yeah, yeah, never said a word." Henchman 1 said blinking a few times and looking away. He's definitely knows.

Bat-Ninja lets go the man letting him fall toward the ground as he screams as he gets closer to the ground, then Bat-Ninja pulls a thin string that's still tied to the guy's ankle stopping him from just a few inches to the solid concert.

"What did your boss told you about the techs?" Bat-Ninja asked again.

"I don't know, what he said didn't made much sense." Henchman 1 answered panting.

"Just tell me what you know, or you'll literally be swimming with the fishes." Bat-Ninja threatened as he pulls him up and swings the upside-down man back and forth.

"No, no, no, no, no, no, stop, I tell you what he told me?!" Henchman 1 panicked as he knows he can't swim and regretted not taking the swimming classes his mom wanted him to go.

Bat-Ninja made one up bringing the grown-crying man back up and grabbed him by the neck.

"He… he said something about going to a new place, a new place far different than ours." Henchman 1 revealed.

"What place?" Bat-Ninja asked angry.

"I don't know, I swear, that all he ever said to me and he also gave this weird chocolate bar. Something about giving a real "boom" in the flavor." Henchman 1 mentioned.

"(Boom…)" Bat-Ninja thought until he realized what that means and quickly push the guy away, then a big explosion pops from Henchman 1's stomach destroying him and blowing Bat-Ninja away as he falls down to the ground inside the warehouse.

"Darn it, I was hoping that guy would take you to Hell with him." A high-pitch young man voice disappointed that his trap didn't work.

"You always been sick of insane, Jaakuna warai." Bat-Ninja growled as he slowly gets up.

An insane laugh erupts echoing all over the warehouse as a young man looks to be about the same age as Bat-Ninja with his face completely white with spiky green hair and yellow eyes, wearing a purple-white clothing that's consist of old-fashion Japanese business clothing with green polka dots on the top and red dots on the pants.

"Glad you could "drop" in, I wouldn't want you miss the surprise I got for you!" Jaakuna warai punned.

"So, this whole heist was just a setup to get me here?" Bat-Ninja figured it out.

"Bingo! For guessing that right, your prize… a one-way vacation trip FOREVER!" Jaakuna warai shouted holding up a device with purple liquid inside.

"This baby right is called the Quake Engine, it was made created by that smart-ass gorilla for time travel, my mentor even told me that he was VERY close to ruling Japan too. Then I got an interesting idea." Jaakuna warai grinned as he began doing some wiring with Quake Engine.

"If this baby can send you back to different time, then how about to another dimension, wouldn't that be fun?" Jaakuna warai laughed.

"(I can't let him get away with that Quake Engine, if that device can send him anywhere in time and space then all will be in danger!)" Bat-Ninja thought and quickly tackle the clown boy making him drop the Quake Engine.

"Fuck Batty, I'm not letting spoiled my fun this time!" Jaakuna warai grunted before punching Bat-Ninja off.

Bat-Ninja got up on his feet to quickly block a slash attack with his arm pads seeing Jaakuna warai holding two fans with razor-sharp spikes.

"Hope you like that punchline because not here comes the fan-dance of death!" Jaakuna warai declared charging at Bat-Ninja.

Bat-Ninja blocks the crazy-boy's attacks and dodging some for a while until he sandwiched jab his hand letting go of one fan and kick the other fan out before uppercut Jaakuna warai a few feet away.

"Looks like you need the vacation, in Arkham." Bat-Ninja said.

"Oh, I don't think so…" Jaakuna warai giggled before showing he has the Quake Engine in his hand and its already turn on.

The purple light engulfed everything within the warehouse as Bat-Ninja brace himself for whatever's about to happen and Jaakuna warai just laughs insanely as the light completely consumes them for seconds later, it faded in an instant showing that everything looks normal. Except that Bat-Ninja and Jaakuna warai are nowhere to be found as there is a burn circle where the two were last standing with a single smoke sizzling from the center.
