This is not only going to be a gigantic list of demi-gods, gods and monsters with their descriptions
The Demi-God Files
Percy Jackson( This is going to be a long one)
Abilities:
Water bending- The ability to use his strength to shape ,change and even
summon water.
Water healing- Percy J. is healed by contact with any kind of water, though seawater works best.
Minor Heat Resistance- Percy J. is more resistant to heat though not immune.
Fighting skills and weapon preference: Riptide is Percy's main weapon and it takes the shape of a pen when not in weapon form. It can be turned into its sword form by uncapping the pen. What makes Riptide unique is the fact that its imbued with the essence of Zoe, and was once wielded by Hercules.
On the battle field Percy is unstoppable, plowing through monsters and demi-gods with ease, but due to his fatal flaw of loyalty his enemies often kidnap his friend and family as hostages and force him to surrender.
Personality and fatal flaw(If the hero's[or heroine's] fatal flaw isn't mentioned in the stories, I'll just write down what I think is their fatal flaw or just write undiscovered)
Percy is a natural leader and is fiercely loyal to his loved ones
