Years have passed since that faithful day, with Percy keeping his promise to write, and living on the streets. He survived from dumpster diving, pick pocketing and anything he could get away with. Using the library, he managed to learn basic survival techniques, along with anything else he could get his hands on. Like monster books for instance.
He compiled everything in a set of notebooks, which he bought with the money he pick pocketing, along with buying some food.
He did manage to master his ability to shapeshift, along with finding out his incredible strength and durability. He also managed to learn about his power to control storms and create Natural disasters. Even poison, how cool was that? This was after an unfortunate incident with the police in Washington DC, where he couldn't Shape Shift, and wished an earthquake stop or at least delayed his pursuers.
He eventually settled in Detroit Michigan, mainly for the high population and its extensive sewers were he could hide in.
Time continued to pass, with Percy becoming a bit of a monster lover, he saw dozens of monsters over the years, and traced them back to Greek Mythology. Since monsters must be real, then Gods, the underworld and everything else must be real as well.
Knowing this, he tried to figure out his father, as he could do things no other mortal could. This search was met with nothing; no other gods or even Goddesses have the ability to shapeshift, or use most Natural Disasters. The big three came close, but not a match. So he called his mother and asked her. He told her about how he knew that Greek mythology was real; she then gave him the biggest shock of his life. His Father was Typhon, the strongest monster, and the storm giant. A good thing out of this was that he created a monster form similar to Typhon regular form. Mainly because it made him feel slightly closer to his father.
The form he created was about 12 feet tall, bat like wings, along with black hair, regular human feet, thick skin, snake tipped fingers which could inject or spit venom that was similar to the Inland Taipan, and could become regular figures if he wished it. Along with Fire Breathe and a massive increase to strength and endurance, with a higher healing factor. This has become his favorite form, besides his human form, the form he used to kill Gabe and a giant monster wolf he created after reading the legend of Fenrir. He spends most of his time in these forms, using the library to learned Martial Arts and creates new ones with his forms abilities. His favorite is creating new venoms and toxins to use against people who threaten him; they even work on monsters which was a plus.
He also learned that the only way to kill a monster is using Celestial Bronze weapons, or by being another monster.
He could transform into a monster and use his powers, but what about when he runs out of energy? What will he do then?
The answer came to him, he needed immortal allies, and his mother recommended Hephaestus, for two reasons. He is one of the most level-headed of gods, and he was the greatest blacksmith.
This lead to Percy, staring at a tall, well-muscled man, with an artificial limb, staring down at him.
"Hello." The man said kindly to the scarred boy, with a hint of curiosity.
'Interesting, he has the aura of a demi god, but also that of a monster. Fascinating.'Hephaestus thought to himself as he continued to examine the young boy.
"What are you, I know that you are not a true demi-god, and have the aura of a monster."Hephaestus asked, Percy then answered seeing no reason to lie, to hopefully a possible comrade.
"I am the only demigod son of Typhon." He stated with complete certainty, Hephaestus almost believed him. One thought broke that though, the son of Typhon part, father of all monsters.
Percy seeing that Hephaestus didn't believe him, transformed into the Typhon counterpart. Once again shocking the god of the forge into almost speechlessness.
"Why did you pray to me?" Hephaestus then asked.
"I would like an immortal ally, as Zeus will most likely try to kill me. You are one of the most level-headed of the gods, and you are underestimated. People think you are only good at making weapons, but that is not all you are the god of." Percy explained his reasons, with Hephaestus nodding. It was a sound reason, and he could detect no lies from the unique boy.
"Fine, I will help you." Hephaestus said after a moment of silence.
"You will first need some celestial bronze weapons, and maybe some armor. Along with a backpack." Hephaestus started to mutter to himself, going over everything in his mind. Percy meanwhile stood silently waiting for the forge god to finish his mumblings.
"Ok, here is a basic sword and shield, I will make something better when I have an idea about what will best suit you, here is also a dagger, and a pair of light armor as well." Hephaestus said, summoning the mentioned items. Along with a black one strap back pack, that will hold anything and still feel as if it was empty.
"Thank you." Percy said grateful, the two then began to converse about their lives, similar to two old friends catching up.
"Do you have anything that could help the scars?" Percy asked as they were getting ready to part ways for the day.
"Healing is Apollo's area of expertise, I repair and build. Not heal."Hephaestus said to the crestfallen boy.
Over the years he gained three new weapons from Hephaestus. He received a set of bronze and steel chains, which wrap around his arms in the form of tattoos, as well as dual swords called Cataclysm and Apocalypse, and lastly, a bow. The sword were both pitch black with glowing red runes, they can either be set on fire at a command, or amplify his powers over Natural Disasters. The two Chains called the chains of Tartarus, were chains that could also be set on fire and bind even a god, as long as Percy has the energy for it. They could also help with his powers.
The bow was nothing special at first glance; simple wood with bronze tips, the real fun was the arrows. Arrows for everything, exploding, poison, recon, fake death, tranquilizer and basic bronze tipped arrows.
In thanks, Percy helped Hephaestus out, weather with a project, or just to talk. They both found themselves with a comrade. Bother were outcasts, Percy with his looks and abilities, while Hephaestus also with his looks and solitary nature. They developed an almost brotherly bond, despite the age difference.
Due to his life, he became the accomplished thief and fighter. He stole weapons like guns, and knives. Along with some clothes, food, a Sony Walkman, and even an electric guitar. He was also in a constant fight with gangs which allowed him to gain fighting experience, and become ruthless and unforgiving to his enemies. He even based a shape in the form off movies and video games, because why not and besides, Alduin was cool, a world eater, but cool. Too bad he couldn't use shouts, he tried but whatever.
Unknown to Percy his life is about to change, be it Good or Bad.
