One day Poseidon was out on patrol when he saw a huge Land Hydra destroying the city/state of Athens he knew he had to help out. The cities defenses were not doing well every time they took a chunk out of the beast it just healed by itself. Poseidon Knew that this was not his fight so he called for his Ultra Omega Hydro Dragon! Now it was a fair Fight so he ordered it to wash the Hydra away using his Hydro Cannons. But just as they thought it was over the Land Hydra was self destructing right in the city so the Hydro Dragon put a water shield over the Hydra so it would only destroy itself not the city/state so then the
city/state was saved and Poseidon flew off on his Hydro Dragon.
