So I kind of lied. (Y/n) in this story is OP. Period. Here's an example for the future.

This won't give away critical plot, but...Spoilers alert!!!

(Third Person POV):

At the center of Tartaros' headquarters stood three demons. They were staring at the archive magic screens in wonder. A yellow spiky demon was tapping away on the keyboard. Suddenly, they let out a sound of confusion.

Kyoka:"What is it, Franmalth?" The feminine demon with green wing-like horns sticking out of her head asked. The yellow demon now known as, Franmath, pointed at one of the screens.

Franmalth:"You said we dealt with all of the Fairy Tail scouts, correct?" He questioned his superior. Kyoka nodded.

Kyoka:"Yes. All of the demons we sent came back fine. Except for Jackal and Tempester." She confirmed. Then the other feminine demon with large breasts raised her finger.

Seilah:"Don't forget the Devil' Cross Legion. They never returned for some reason." She pointed out. Kyoka grit her teeth in frustration.

Kyoka:"Yes. They were one of our failures, but that shouldn't be a worry." She tried to assure. However, the other two in her presence thought otherwise.

The Devil's Cross Legion were their elite demon spawn hit squad. It was composed of 666 demons. Together their power would match Kyoka. For them to be defeated would be impossible. At least until now.

Franmalth:"I'm not so sure, but we have a problem." He told the other two. Then the three demons looked at the screen.

There was a lone figure making their way towards Tartaros' base. He had a (f/c) cloak that was tattered and flapping in the wind. His (h/c) hair and (s/c) skin were tainted with black and red liquid. No doubt blood and something evil.

A blue striped scarf covered most of his face, but even the three demons could feel the emotion emitted from the man. After all, nature was reflecting on his emotions.

Static filled the air to a point where electricity formed. Wind gusts blew around violently. Giant waves formed and flooded areas. His footsteps left smoke and embers. The air felt cold where his burning footprint didn't fill.

The sky then darkened. Storm clouds covered the air and lightning began to strike. The earth rumbled with every step the male took. Finally, the vest he wore shifted aside clearly. The three demons' eyes widened in shock. On the left side of his chest, right where his heart lied, was the Fairy Tail emblem. It was glowing bright golden.

Then the male removed the scarf covering his face. It revealed a scowl and his eyes. One was pure black and the other glowed golden.

Kyoka:"Who the hell is that?" She asked and began to tremble. His power felt more immense than either of these three have ever experienced.

Suddenly, the man let out a roar of indescribable anger. What happened next was unbelievable. One single lighting bolt struck down on the floating cubic island. Then the damage went into effect. The area the man stood on island engulfed into a fiery explosion.

It created a shockwave that knocked the three demons off their feet. The Tartaros base rocked violently and parts of it crumble from the sheer force elicited from the intruder.

Kyoka:"What is this power?!" She asked in disbelief. The intruder's roar of fury boomed across the land and continent. Finally, the explosion died down to reveal the aftermath.

One third of Tartaros' cube island was gone. Completely wiped away. The two of the three demons monitoring the situation slowly stood up in pain. Even though the attack wasn't directly aimed towards them, it left an effect.

Seilah:"Why do I feel injured?" She asked weakly. Franmalth moaned in pain and was out cold. Kyoka stood up and looked at the monitor. Her eyes widened with fear she had never felt.

Kyoka:"No...it can't be..." She muttered with a shaky voice. It began to scare Seilah as well.

Seilah:"Who is that?!" She demanded. Kyoka slowly turned her head and gave Seilah a trembling stare.

Kyoka:"H-He took out one third of the island with one scream." She stuttered. Seilah than grabbed her superior and shook her out of the fearful trance.

Seilah:"Tell me what or who he is!!! Just tell me something!!!" She screamed now in terror. Suddenly, they heard the footsteps of their comrade. It was a man with black hair and silver armor. His name was Silver.

Silver:"That right there is a first generation demon slayer." He answered grimly. The demons turned to look at the screen. It was cracked and glitchy, but still projected an image.

The man on the screen was now covered with black markings that took over half of his body. He barely looked human anymore, but still his anger was one of humanity.

Silver:"That is (Y/n) (L/n)." He announced, and the entire room grew cold at the mention of his name. Then (Y/n) spoke.

(Y/n):"WHERE'S ERZA?!?!??!!" He roared and made the land tremble once again. His wrath has only begun. Once (Y/n) is finished, every single demon would do anything for death.

A/n: Just something that demonstrates his power potential in the far future. I wanted to write something to share with you all. Until the next actual chapter, bye!
