Monsters, Greeks, andaliens

What happens when Percy Jackson wanders into Mr. Smoothies after a battle? What if Ben Ten and his partner, Rooke, were in there at the time? What would happen when they see Percy killing a monster? What if Percy thinks Ben is a monster? What if Percy goes to the plumber HQ? What will they think of him? What will happen when the Greeks and Romans meet Egyptians?

(I don't know when I might finish it. If a lot of people like it, I will get back to it a lot sooner. So if you like it, let me know.)
