I'm thinking of making an rp. Here's the storyline so far. Please note none of this is finally yet.

Humans (This may include other species), Demons and Gods have been alive for thousands of years. For a long time they lived peacefully. Yet around 1000 thousand years ago the gods entered a civil war. During the war the demons began to attack the humans. Humanity tried to fight back but with the gods busy they failed. Humanity soon fell under the rule of the demons. While the gods where still busy fighting with each other, the demons sealed the portal between the gods and humans. After 500 years of fighting the war finally ended between the gods. Yet they were unable to enter the human realm. So they decided to give a human a large amount of powers. This human would be a God King. The next year the God King was born. After 27 years the God king lead humanity to fight the demons. After 60 years he managed to reclaim the human world but not before being killed by the demon leader. As a result the demons began to invade again but after 100 year when the God King was born he was remade into another human. Once again the new God King leaded humanity to fight against the demons. Once again the demons where defeated. The demons realize that each time they killed the God King he would just be remade. So the demons decided to give the next God King some of there own powers. Then about 2 years ago the next God King was born. Yet he could not control his own powers and created a new race. This race was called the monsters. These monsters attack both the humans and the demons. As a result the God King gave certain individuals powers of both demons and gods to fight these monsters.

Normal: There normal personality. This personality has no powers and is just a regular human. This personality is usually dominating personality.
Light: A guarding type of personality. This personality gains the power of defensives/supportive/healing powers. This personality is usually the 2nd most dominating personality. It may sometimes take over there normally personality becoming the dominate one. This power comes from the God powers of the God King.
Dark: An evil type of personality. This personality is usually the less dominating personality only coming when the person is about to be killed. This personality gives the person much offensive abilities. It may sometimes take over there normally personality. This power comes from the Demons powers of the God King.

So how many people would be interested in this rp? Feel free to post any suggestions or comments.

So explain more about time line, creatures existing there and everything. Fantasy Medieval, super-natural modern or maybe futuristic ?

It takes place in the medieval times.

I'm skeptical. If Gods were unable to enter the new earth then how can they transfer their powers into a human being? Why not then commit suicide and be reborn as a human with godly powers instead? Also they way you portrayed demons it looked like they were afraid of gods powers and hence they had to wait until gods broke out war amongst themselves to plan their invasion of earth. If such was the case would they really have powers to defend against gods onslaught? i mean if theyre the mighty gods what demon barrier can really keep them at bay? I also don't understand how the last God King who goes around pillaging both humans and demons decided to give some of his powers to humans to fight against monsters who is coincidentally what he's become?

Your assuming to many things.

God King created monsters by accident. The God King helps humans. Also these gods aren't all mighty. They have the strenght of the Greek gods. In one case of Greek mythology human managed to trap Thanatos the God of Death. The demons also used humans to increase the power of the barrier. The barrier stops physical objects but not magical abilities. Gods can give human powers from there own realm. Also if a God dies then he dies. The God King isn't affected by this rule since he has the power of several gods and is still a human. The God King does not become a monster. Demons were not afraid of Gods. They just saw an opening and took it. The most recent God King is now in hiding trying to control his new powers.

I read through the 1st post but I'm a little confused.

Perhaps you can state the aims of each race and what their abilities are? I'm unsure whether the various races in this RP are fighting each other or are they just living side by side? Abilities explanation might help too. You won't want Humans to be able to shoot Goku fire balls and Gods only able to wield swords right? Hence, more elaboration will help. :)

I got the rp running in the one mangas forum. It more detailed there: http://forum.onemanga.com/showthread.php?t=13531. If you still have any question feel free to ask.
