Reborn as a Saiyan in marvel

William was sent flying from the impact of the explosion and was smashed into a nearby building before being forced to dodge to the left as a red boot came crashing towards him, "BOOM!" the building collapsed on top of Superman and William flew up into the sky and fired off a series of ki attacks.

"BOOM, BOOM, BOOM!" the building exploded into rubble due to the attacks leaving a small mushroom cloud that was suddenly pierced from the top, "GET OFF MY PLANET!" Superman lands a strong punch, "BOOM!" hitting William on his jaw and sending him into deep orbit.

William allows himself to be carried by the momentum and soon arrives halfway to the moon and begins panicking slightly as he has never been to space before however after a moment realizes his biology and his suit are working in conjunction to make fighting in space possible!

A yellow glint catches his eye, and William remembers the yellow ring of Fear and takes it out before marveling at its design and sliding it onto his finger yellow veins extend from William's pupils before his Green and black suit becomes Yellow and black with the symbol of fear emblazoned on the front and having a faint yellow shimmering aura surrounding the suit.

Feeling the surge of new power William imagined a yellow ball filled to the brim with his ki energy and it formed in front of him, "boom!" the sound of someone breaking the sound barrier was heard and he looked down to see Superman flying with his eyes glowing a deep red!

"Here is a little tribute to the great Yamcha, TERROR BALL!" he launches the fearful ball, and Superman attempts to punch through it as the ball approaches his fist a sinister smile appears on William's face, and he flicks two of his fingers upward causing the ball of energy to move upward effectively dodging the punch before slamming hard into Superman's face and forcing a ribbon of blood from his nose!

William's smile continued to widen as he flicked his fingers from left to right, "BANG, THWACK" The ball struck Superman's ribs and spun around before slamming into his kidney!

"HWAGG!" Superman coughs up blood and the red in his eyes intensifies however what happens next causes Superman to completely drop his guard, and the Fear orb begins to reshape into the image of a very pregnant Lois Lane although in a yellow tint!

"L... Lois... I've missed you so much!" tears formed in Superman's eyes as he approached and hugged the clone of his dead wife, the clone opened its mouth and spoke suddenly catching Superman off guard, "I could never love what you've become!" before her form began to take on nightmarish proportions and proceeded to explode, "BOOM!" a massive cloud of energy exploded outward directly onto Superman's face and body sending the Kryptonian flying toward the surface of earth so fast that he generated a corona of fire around him.

A massive yellow fist crashed into William from behind and sent him tumbling forward, he turned around to see a red alien with a thin mustache surrounded by a series of other fear users!

"Surrender the ring and we will kill you quickly, or don't and we get to have fun either way works really!" The red alien arrogantly stated as he stared condescendingly 

William ignored the alien and continued playing with the yellow energy in the distance, a vein formed on the red alien's forehead, "You dare... hahaha you have guts, boys... tear them out!"

A dozen yellow lanterns began charging at him and using their rings to summon a vast array of nightmarish creatures and devices, "HAH!" William stretches his hands outward forming a barrier of fear energy and ki which looks like a set of yellow plates placed within a green energy mesh, "BOOOM!" A yellow tentacle smashed into the barrier causing it to vibrate but nothing more, "Crack!" a spiked whip lashed the barrier and didn't leave a mark a series of fear energy attacks blended and managed to form a small crack on the shield.

"My turn!" William says before summoning a fear energy image of Thor who appeared amidst yellow lightning as he spun his mighty hammer, "HOOOO!" Clone Thor yelled out as a massive bolt of yellow lightning struck his hammer and he began charging at the enemy lanterns who put up barriers on top of each other after feeling the threat of the opponent 

William was tired of zero-gravity fighting and began descending back to the planet below as Clone Thor held off the lanterns. He arrived back in the sky over the metropolis to witness the sea retreating to its territory, and the militaries of the world sighed in relief!

 Superman lies in a crater below, cradled by Wonder Woman who flies him back to safety and is followed by the rest of the regime, who are flight capable.

William's feet touch the earth below as the sea falls back and people begin leaving the buildings and flooding the streets.

It wasn't long before they noticed William in his suit and suddenly felt a wave of fear, as people wearing that suit typically worked for the regime. Ignoring them, he began to fly again, landing on one of the taller buildings. He paused for a moment to think about his next move. Before long, a series of yellow flashes from the upper orbit caught his attention, the fear energy construct had been defeated at great effort by the Yellow Lantern Corps at the cost of several of their members. 

The emptiness of space above the earth was littered with corpses surrounded by a yellow light that circled once before heading into deep space to choose another host, the red-skinned alien's eyes were bloodshot from the close call, the construct hammer was mere inches from his face before the construct was destroyed leaving a lingering fear in the lantern's hearts simultaneously causing him distress as well as empowering him!

Wreathed in his yellow light he and several of his surviving lanterns descended to the earth below and after a few seconds of searching saw the yellow suit from a distance and begin their approach simultaneously the red-skinned alien radios for backup, "This is Sinestro I need backup in metropolis specifically the Lecorps tower!" a moment passed before he heard a reply, "Shazam and Black Adam are on route!" a smile formed on Sinestro's face as he approached the tallest building, "Form up around him, leave him no means of escape!" Sinestro ordered the corpsmen via the rings!

William had a relaxed expression as he watched the enemies surrounding him, "Oh you are still here?" he looked Sinestro up and down, "I expected your head to be on the other side of the solar system by now!" a wicked grin formed on William's face as his hand reached into a separate space and pulling forth a mystical staff.

As soon as his ring hand made contact with the mystical staff, it began to transform. The shaft of the staff extended by several feet, and the Uru metal developed yellow veins that etched their way from the metal into the mystical wood beneath. At the crown of the staff, a yellow blade formed, warping into a perfect setting that allowed the blade to extend several more inches after being secured.

William swung his spear toward one of the lanterns that attempted to put up a multi-layered shield however what happened next caused the rest of the lanterns to gulp in fear, "ZIP!" the spear disappeared in his hand, and before the lantern could react, "CRACK!" the body of the lantern was impaled on his construct from behind!

The yellow light left his eyes, and his suit disappeared leaving a near-naked purple alien with pointy ears, the ring began to fly out into space the view of which was blocked by a sudden appearance of storm clouds!

"RUMBLE!" 

The Sinestro Corps began firing blasts of energy and creating constructs to assault William who after retrieving his deadly weapon began spinning the spear in position, "DING, BANG, BOOM, CRACK BOOOM!" 

William blocked what he could and destroyed what he couldn't block however a construct tentacle grabbed him from behind and slammed him back into the roof of the building and he lay there immobilized by the tentacle, suddenly William heard a couple of voices roaring in unison, "SHAZAAAAM!" a massive lightning bolt descended from the sky and struck William and the building under him, "BOOOOOM!" the massive bolt of godly lightning blasted through the Lecorps building and fried a few civilians inside and left William in a crater with lightning coursing through his body!

Two beings descended from the sky one wreathed in red the other in black.

The one in black approached William before he grabbed him by his neck and lifted him however William suddenly opened his eyes and grabbed the startled man before slamming his head into the roof of the Lex Corps sending a shockwave down the length of the building, "BOOM!" his face was buried into the cement and William was about to smash his foot down to finish his opponent when yellow chains wrapped his limbs and held him in place!

"BOOM!" the red one arrived in front of William and threw a lightning-coated punch to his face which caused William to lose his footing, and he was suddenly drug by the chains off the building and out into the open air, "RUMBLE!" the building rumbled as the one in black successfully removed his face from the building!

"YOU DARE!" His eyes were bloodshot from embarrassment, and he began charging his body with his godly lightning before launching it at William, "CRACK!" the chains around William broke and his aura took on a golden sheen that seemed to blend into his suit and his muscles expanded to great proportions!

William raised his weapon and absorbed the lightning which began turning green under the control of the young Saiyan causing the one in black to be stunned as he gazed at the weapon in William's hand!

"I like your weapon, I'll put it to good use after I tear it from your cold dead hands!" He says as lightning fills his eyes as he nods toward the one in red who also began charging his lightning, the two charge at William and throw a barrage of attacks with the one in black going high and attempting to uppercut William in his jaw, the one in red attempted to go for the knees!

William saw through their attempt and smiled, "EXTEND!" the spear in his hand extended its length from both sides, "Squelch!" the one in black was pierced through his shoulder and carried into the distance with the blunt end smashing into the face of the red one and rendering him unconscious from the combined force before retracting the spear to a handheld size!

The one in red began to fall from the sky however a pair of hands caught the man and began flying so fast that he appeared to have teleported to another town, a town covered in nearly constant cloud cover and rain!

The man in black flew back over with a noticeable and very large open wound on his shoulder, "Where did he go? Where is the boy?" he roared at the remaining Sinestro Corps members who were confused by their inability to perceive the speed of their opponent!

"Calm yourself Adam we need to regroup before we face him again, let's gather all the heavy hitters!" Sinestro said before signaling his men to fall back and stand by, he looked back to Black Adam who had already vanished and sighed!

In a fortress made of crystals Superman was going over footage while Wonder Woman provided his shoulders a massage however it wasn't long before her hands began to wander down below, "Clasp!" Superman grabs her wrist and turns his head with a questioning gaze, "What are you doing Diana?"

She presses her chest against his back and says, "You just seem tense I thought I'd help!" her breath brushing against his ears and rubbing his chest!

"Diana?" he says but she puts a finger to his lips and within a few minutes the room they are in is filled with wet noises!

[In Gotham]

William arrives at a rooftop holding the man in red and sets him down with a slight impact, "Crash!" he falls into a group of trash cans the sound and impact of which cause him to startle awake, "HUH WHO?" he said as he began floating before an arm grabs him from around the head, "Do you want to be a good boy, or do you need punishment?"

The man in red had lightning forming in his eyes, "SHAZAAM!" he roared; however, William grabbed him with his other hand and held him aloft just in time for the lightning to strike the man's body, "POOF!" a puff of smoke encapsulates the duo on the roof and when it clears William is seen holding a kid up by his shirt, "W... Who are you?" he asks as he struggles in William's grip.

"I'm the one that's going to save your life if you are willing to listen!" he says before setting down the kid who glares up at William before the glare becomes questioning, "What do you mean to save my life?" he questions with clear derision in his eyes.

"One day Superman threatens to begin destroying towns and cities and even entire dimensions, you begin to take exception to this all culminating to the point where you say a word that seals your fate..." He pauses before staring deep into the boy's eyes, "Lois!" he says as a peel of thunder goes off as if to punctuate the word!

The boy is about to say something but can't, he has noticed Superman's increased manic behavior and the fact that he has even killed civilians who were merely protesting against the harshness of his rule.

He finally works up the courage to say something when a shadow is cast over them and a dark silhouette is seen perched on a nearby roof, "Batman?" the boy says with confusion.

The silhouette approaches glaring at Billy before he turns his head to William with confusion, "I know him, but who are you?" Batman's eyes squint as he goes over every hero or villain he has ever encountered, "Names Viridian, I'm no one important and am merely passing through!" Batman's eyes turn into slits before he walks over to Billy and picks him up by his shirt before squeezing a pressure point on his neck causing the boy to collapse in Batman's arms.

William seeing this is stunned but doesn't show it.

Batman slings the boy onto his shoulder and begins walking toward William, "Follow me, Viridian!" he says before jumping off the edge and using a zip line to swing down to his vehicle below.

"ROAR!" fire shoots out of the exhaust of the vehicle as he speeds through Gotham toward the secret hideout with William floating next to him.

They arrived at a waterfall and passed under it arriving at a small garage filled with specialty vehicles used by the bat family, "Touch nothing!" Batman's rough voice echoes through the garage just as William is about to touch one of the vehicles.

He turns away and heads deeper into the compound following Batman's steps and arrives at a large room with a big table and a massive computer, he lays the boy down on the table before he walks to the computer and pulls up a video of William fighting Superman in orbit.

"How are you able to fight him evenly and are you Willing to share the source of your strength?" He asks as his hands fold over themselves, "Of course, I won't ask something for nothing if you do offer to share your power or at least help ill off you this!" he reaches in his belt and pulls out an emerald ring, "A green lantern ring that I've been unable to use!" Batman states and sets the ring down on the table.

William stares at the ring for a moment before turning back to Batman, "Most of my strength is a combination of hard work and racial trait combinations, however, I may be able to help you with your fight against Superman!"

Batman walks to the center of a platform and gestures for William to follow.

William walks to the platform, "What have you got in mind?" he questions the dark knight in front of him, "I want you to show me your skills, spar with me!" he throws a smoke bomb toward William which explodes into a cloud, "Shink, Shink!" a couple of Batarangs came flying in his direction from two sides! 

"Ding, Ding!" William deflects the two Batarangs but he senses some movement from above and uses one of his arms to block, "CRACK!" A large boot slammed into his arm from the smoke sending William sliding back from the force, "OOOH nice!" William had a smile on his face when the attack landed but before he could regain his footing a zipline between William's feet began pulling and a boot slammed into William's stomach.

Batman slid between William's legs and appeared on the other side attempting to throw a spinning kick, "Bang!" To Batman's utter shock, William's hand grasped his leg and stopped the attack in its tracks.

Batman's visor dropped and a bright light began flashing into William's eyes causing him temporary blindness and disorientation, however, "ARRG!" Batman struggled valiantly to escape the grasp on his leg however nothing worked.

William took his middle finger and thumb and came near Batman's armored head, "SMACK!" he flicked Batman in his forehead knocking the man out!

After Batman lost consciousness William carried him to his chair and grabbed the ring from the table and slid it onto his middle finger, "WHOOSH!" the energy within him surged forward and sent papers and small objects crashing into walls, his yellow and black suit began to shift to yellow and green with each color trying to assume dominance over the other before settling on a delicate balance! 

His new suit was a streamlined blend of yellow and green with thin black veins spreading from the center and separating the two colors as if forming a barrier.

Batman woke up and saw this and nodded, "Normally Will and Fear would attempt to destroy the other, but you use what I'm assuming as your primary source of power as a membrane to prevent conflict!" his mind went into overdrive as he was determined to work out the mechanics of Williams power.

William lifted his hand and a ball of ki swirling with a chaotic mass of will and fear energy coursing through it he aimed his fingers and the chaotic mass of energy towards a nearby target, "PEEW!" a beam of chaotic energy hit the target dead center causing the target to begin to deform and become embedded into the cavern wall!

"Needs work but it's a start!" William says as he is impressed by the extra power such a small attack gained just by adding two conflicting energies.

Batman approaches William and looks at the target and back at William, "Don't break my things!" Batman says with a glare before sighing, "I'll get to the point the insurgency against Superman's regime could use someone with your talents, you could be instrumental in tipping the tides!"
