Poseidon, the god of the seas and earthquakes controls the waves. He is one of the three main Olympians.

That's difficult to answer. The names of the God of the Underworld were often conflated and confused, which makes this difficult to answer clearly. In most modern tellings, Pluto was the name of the Roman version of Hades, the Greek god of the Underworld. Hades was also the name of the Greek Underworld, while the Romans called it Orcus. More accurately, though, Classical Age Greeks were already calling Hades by another name, for fear of drawing his ire by using his name too often (or to prevent confusion with the name of the land itself). Usually, they called him Ploutodotēs (giver of wealth), or the diminutive Ploutōn. This was later Latinzed to 'Pluto'. The Romans actually didn't refer to their underworld god as "Pluto" (unless they were retelling the name from Greek - which most Romans spoke), but rather as Dis Pater, which means "Rich Father." They would also sometimes called him Orcus, after the land over which he ruled. So, in summation, Pluto is actually Greek, though so is Hades.
