Deciding to "wash their hands" with this business, the Gods of Olympus have chosen the currently strongest Greek Demi-God and Roman Demi-God to make into Immortals as the "Representative Gods" of each Demi-God aspect: Roman or Greek, for a number of times these two sides would clash in indecisive battles and coupled with parallel missions by Demi-Gods - skating both of their Nations unintentionally closer to war.

Greeks

 * Percy - Born a son of Poseidon and acting as free as the sea, Percy was raised as the Godly representative of Greece and such his free will coupled with his disobedience shows the true nature of Greece, what the Romans see as Barbaric is in fact that Greece is as free as the sea making a son of Poseidon the perfect representative.

Romans

 * Jason - The Son of Jupiter and therefore the Roman Equivalent of the Greek God: Zeus, even as a Greek God Zeus was serious and demanded obedience quite similar to the modern day Romans and that has been enhanced by developing further his Roman features, because of Jupiter's refinement it would only be perfect that his son commanded the Roman Demi-God aspect due to his disciplined and militaristic personality inheritance.
