Phorcys

"I promised to tell you everything you need to know. The thing is, however, you don’t really need to know anything. You see, even if you made it to Rome, which is quite unlikely, you’d never defeat my giant brothers without a god fighting at your side. And what god would help you? So I have a better plan. You’re not leaving. You’re VIPs—Very Important Prisoners!"

- Phorcys to Frank and Percy

Phorcys (or Phorkys, from Ancient Greek: Φόρκυς), is a god of the hidden dangers of the deep. He is a primordial sea god, generally cited as the son of Pontus and Gaea. His wife was Keto, and he is most notable in myth for fathering by Keto a host of monstrous children collectively known as the Phorcydes.

The Mark of Athena
Percy Jackson, Frank Zhang, and Gleeson Hedge met Phorcys and his sister Keto at the Georgia Aquarium in Atlanta. He let Percy, Frank, and Gleeson Hedge in for three denari and gave them the V.I.P tour. He showed them the rare monsters he had in captivity, but Keto soon took Coach Hedge to a different area to show him more dangerous monsters. Then Phorcys trapped Frank and Percy in their own tank with plans to make them fight everyday for the entertainment of the visitors. Percy tried to control the water, but failed because it was Phorcys' territory. He and Frank, who turned into a koi fish, tried to get Hedge's attention. Frank, Percy, and Hedge then broke the glass tank, and escaped with Percy promising to return and free the monsters and sea creatures that Phorcys had kept in captivity.

Personality
Phorcys was very robust. He had the tendency to act on the more flashy side of things. Instead of relying on information to entertain tour groups, he used fireworks; he felt that too much information would bore quests, which led to him constantly getting angry at Keto. He was also, playful, joking around with Percy and Frank before finally trapping them. Much like Keto, he had no problems mistreating sea creatures except if it prevented them from performing tricks.

Appearance
Phorcys wore a wet suit that appeared to be several shades of green. There were glittery silver words printed on the side: PORKY'S FOLLIES. In his greasy wiry hair, he wore a microphone headset. His eyes were milky blue with one higher than the other. When he smiled, his smile looked like it was being peeled back.

Phorcys had many features similar to a crab. He tended to scuttle around sideways on his bowed legs. He had a hunched back. He also kept his arms in the air as if holding plates.

Abilities
Being a god of the sea, Phorcys had some level of control over sea water. He used his ability to aid in his control of the aquarium and all the creatures kept there. He was able to overpower Percy's ability to control water, but only as long as he was in his immediate area.
