The Invincible Full-Moon System

In the world of Supernaturals, the different races varied in terms of powers and customs but a single common fact, stands strong. Those who have the bloodline of the Origin will always be the strongest of their kind.

No matter whether it was low-rank, mid-rank, or high-rank Supernaturals, this fact stood.

Having been blessed and given power by a higher being, the Origins didn't only possess the fundamental power of their race but also experienced a minor ascension, turning their blood into the associated power itself.

Because of that, the descendants that came directly from them were powerhouses.

Hard for others to compete with these royals.

However, out of the entire Supernatural races, the Werewolves are slightly different.

Of course, the Werewolves who were the direct descendants of the Origin were stronger but in the Werewolf society, there were a few instances, where others, could compete, and even as surprising as it might be, rule over the royals only under the Origin.

It was naturally due to their overwhelming sheer strength.

Despite their weaker bloodlines, these Werewolves are favored by the Lunirich Gods.

So favored that they could even be stronger than the Princes or Princesses.

A freak incident that caught not only the Werewolves but the Supernatural world off guard.

Recognizing these Werewolves, the Origin declared a shocking decision.

He announced that those who are blessed with power will also be able to be the rulers.

Following the disappearance of the Werewolf Origin—there were a couple of rulers that were not from the royal families because of his declaration. All of these events, played inside all of the Alpha Primes when they heard what Prince Alaric said.

And no matter how much they try to deny it, Prince Alaric was right.

As of this moment, the Royal Black Prince is the strongest and, therefore, the rightful ruler.

Swoosh~

Despite the nervousness, Mavok and the two Alpha Primes got down from their mounts.

Giving a subtle glance, the mounts nodded and leaped away.

All three of the mounts leaped—in different directions, creating a triangle-shaped formation, with the steadily approaching Royal Black Prince at the center. Then—the mounts bite down the ground, channeling a lump of energy and shooting it into the earth.

Being the mounts of a Prince and Alpha Primes, these mutated wolves aren't normal.

One of their fangs was replaced by an artifact.

It could create a barrier that is highly effective in keeping clashes of auras within its confines.

And with more fangs supplying its energy, the confine became stronger and stronger.

As soon as the energy combined, a massive pyramid-shaped barrier was created.

Glancing over to Prince Alaric, Mavok raised an eyebrow.

"Your Highness, are you not going to come with us?"

"No, I have my fills already. I'll watch from a safe distance"

Mavok nodded before he nudged his chin.

In response, the two Alpha Primes leap to either side, making a distance between them.

Before engaging in any kind of deal or conversation with a new, friendly person, it's a custom in the Werewolf society—to exchange claws first. Claws reveal the person, and the Werewolf could feel the others' intentions through a clash.

Fixing his gaze on Rex, the Alpha Prime on the right got down on all four.

Grrr!!

A vicious growl crawled its way out of gritted teeth as a purple dot appeared on his forehead.

His black furs fluttered with sparks of purple kingly energy.

One could see the purple dot began drawing a powerful symbol, rather, a King Mark.

It took a good couple of seconds for the King Mark to complete, sourcing the Violet Moon.

Aooouu!!

He unleashed a mighty howl as his violet moon-kingly energy basted out of him like flames.

Not stopping at him, the Alpha Prime on the left also prepared himself.

A green dot manifested on his forehead—he took a knee down before stabbing his claws into the ground with a violent thrust. Upon doing that—the veins underneath his skin glowed with a green hue, starting from his arms and spreading to his entire body.

Like the other Alpha Prime, a green kingly energy exploded from him.

And on his forehead, the Harvest Moon King Mark was there to see with all its brilliance.

Rex watched them activate their powers without stopping.

He had learned the Werewolf's custom a long time ago and he knew this wasn't hostility.

It was a greeting gesture between strong Werewolves.

"Violet Moon King Mark—and Harvest Moon King Mark, I hadn't fought anyone like them," He mused, pleasantly surprised by the view. He then turned to Mavok, "Now, what King Mark do you have...?"

Seeing a small smile crossing the Royal Black Prince's lips, Mavok nodded.

His two friends were ready and now it was his turn.

A red dot appeared on Mavok's forehead as he looked down and focused.

Mavok could feel his heartbeat rapidly increasing, hastening the flow of his blood through his bloodstream. His breaths came out rough like a bull, before he raised his elongating claws, to his chest and with one brutal stroke, dragged his claws across his chest.

In an instant, the act caused a sudden increase in his aggression as his King Mark formed.

His eyes glowed red as he flared his chest open.

Such an act was the most familiar to Rex, Mavok has the Blood Moon King Mark.

Roar!!

Using Mavok's roar as a signal, the other two Alpha Primes instant rushed forward.

Knowing that they were battling the Royal Black Prince with fearsome feats such as killing an Executor, the Fifthborn, the two Alpha Primes held nothing back, going all out fro the start. In a violent rush, their legs moved faster like a blur, closing the distance between them.

One that reached Rex first, unsurprisingly, was the Alpha Prime with the Violet Moon.

Concentrating his kingly energy on his claws, he grunted and made a fierce swipe.

Bam!

Crack!

Rex raised his arm to block the swipe but the force from the attack rippled through the point of impact, shooting a massive beam to the other side, cracking the ground, on its path. Such a force was nothing less than expected from an Alpha Prime.

But the attack didn't stop there, a purple gush of energy remained and hovered to above.

It then rapidly morphed and turned into a purple ethereal clone that struck Rex once again.

Seeing this, Rex smiled, this was the first time he had seen a strike like this.

He blocked the attack again while keeping walking forward.

Expecting that the attack wouldn't be enough to do anything to Rex, the Alpha Prime became even more ferocious, striking five strikes followed by another five from the ethereal clone in a mere second, showcasing his speed to the fullest.

"Moon Ability, Five Violet Assault"

Bam!

Upon making a powerful swipe, five purple clones appeared instead of one.

All were stronger than before and struck from different angles.

Five strikes.

First, Rex tilted his body a little, avoiding the vertical heavy strike from above.

Second and third, Rex bent his body forward, seamlessly dodging two strikes from behind.

It made use of his blindspot but Rex was extremely attuned to his surroundings.

Fourth and fifth, Rex raised both hands, stopping them mid-swing.

All of it unfolded in the time it took the Alpha Prime to blink—swift, strong, and unbreakable.

"Is that it?" His baritone voice seeped into the Alpha Prime's ears.

Knowing that this was not the extent of his power—another clone manifested and attacked, the blow caught Rex's chin, a powerful upswing, that forced him to look skyward. Using this moment, the Alpha Prime leaped and thrust his claws, aiming to pierce Rex's eyes.

But at that moment, the Alpha Prime's eyes widened.

Clang!

His claws, reaching longer with purple kingly energy, were stopped mid-track.

Rex caught the claws with nothing but his teeth, catching them as if they were nothing.

A grin crossed his face seeing the Alpha Prime's shocked expression.

Just then, however, the Alpha Prime quickly recovered and quickly leaped out of the way.

Replacing him, dashing from behind with a big amount of green kingly energy, in his mouth was the other Alpha Prime. He reached inches away from Rex's face, before unleashing his mighty roar that blasted a powerful emerald soundwave right to Rex's face.

It was a point-blank attack, enveloping Rex's face entirely.

Such an attack would obliterate others' faces without fail.

Knowing that it was the Royal Black Prince, the Alpha Prime with the Harvest Moon King Mark was hoping that this attack would force the prince to use his King Marks and thus, consider this greeting more seriously.

Seeing that the Royal Black Prince halted in his tracks, the Alpha Prime smirked.

'Good, with this, he would have to take us more seriousl-'

Before the Alpha Prime could finish his thoughts, his eyes widened.

A smirking silhouette could be seen through the torrent of soundwave and before long, the Alpha Prime felt a chill run down his spine when Rex's face, simply came out of the energy, completely unscathed.

Not even a tear on his skin could be seen, it was almost as if he was invincible.

Rex, with his massive hand, grabbed the Alpha Prime's face and lifted him off the ground.

"Y- You're invincible!"

"No, I'm not. I'm simply too strong for you"

Upon saying that, Rex threw the Alpha Prime to the side with a nonchalant swing.

But the Alpha Prime was tossed hard, breaking the sound barrier and rolling for miles away.

It was only then did Rex was face to face with the last Alpha Prime, Mavok.

"Mavok, your Highness. Go easy on me," Mavok declared.

Rex smirked in response.

He could see that the words from Mavok's mouth were the opposite of what he wanted.

"A fellow Alpha of the Blood Moon, I don't think that's what you wanted"

"Your Highness read me too well,"

Scanning Mavok with the System, Rex nodded his head before he continued his advance.

Mavok readied himself but stopped when he saw something.

A red dot appeared on Rex's forehead that soon drew the King Mark.

Unlike the regular King Mark, Mavok could see that there was a thin line, that protruded out of each side of the full moon, an extension, that he had never seen before. Additionally, the kingly energy that seeped out of Rex's King Mark was devastating.

It was unlike what he had ever seen before.

Giving Mavok what he wanted, Rex's eyes glowed crimson.

He then flexed his muscles and bared his fangs to growl menacingly—his energy steaming.

Seeing this, Mavok also leaned forward and growled before he pounced forward.

Fueled with the predatory impulse to test his strength against someone who many deemed to be unbeatable in the new era, Mavok immediately galloped forward on all four—racing in delight at the immense spectacle before him.

His speed quickened with each gallop and his claws glowed bright crimson.

Enhanced by the dripping blood from the open wound on his chest.

Rex also did the same thing, sprinting ahead, matching Mavok's pace as he too, was excited.

"Moon Ability, Savage Impulse!"

"Direct Moon Ability, Brutal Impulse!"

Kaboom!!

A powerful shockwave exploded the moment both of their claws clashed.

Rex was surprised to hear that Mavok's moon ability was similar to his, but then again—both of them have the same Blood Moon—supporting them. Feeling the weight of the attack, Rex nodded in affirmation.

Out of the Alpha Primes, Mavok was definitely the strongest in raw strength.

Despite that, he could be seen struggling, overwhelmed by Rex's kingly energy.

Unlike Mavok's moon ability, his was a direct one—connected to Kaiser himself.

As the clash reached the breaking point, another explosion happened.

Prince Alaric and the other two Alpha Primes waited outside of the smoke, eager for the end.

But as expected, when the wind blew the smoke, Mavok was kneeling.

In front of him was Rex, still standing the same as before.

However, a slight surprise marred Rex's face as he reached for his cheek.

Looking at his hand, he found blood, Mavok was surprisingly able to slice through his skin.

He's quite strong, even stronger than the rulers of the kingdoms, under my empire. It wasn't only for show that the Werewolves are considered a high-rank Supernatural race, even their Alpha Prime was this strong.

But Mavok in particular... he's strong.
