Perseus was not as important to the Romans as to the Greeks, but his name would be the same. While his name didn't change several of the heroes such as Odysseus and Achilleus did have Roman names, Ulysses and Achilles, so it is not just the gods that the Romans changed the names.
Perseus was said to be born in Argos. So back then surnames were not used. So to answer this I wold say his name is Perseus of Argos.

Perseus was Greek.
Perseus was not as important to the Romans as to the Greeks, but his name would be the same. While his name didn't change several of the heroes such as Odysseus and Achilleus did have Roman names, Ulysses and Achilles, so it is not just the gods that the Romans changed the names.
PerseuV was the Greek name, it was translated as Perseus as the Latin name.
The myth of Pegasus is Greek in origin (Perseus is one of Greece's "founder kings") so there is no Roman analog for him. As such, since the name is already in proper syntax, they just called him Pegasus.
Formal, the common name for Perseus today is Percy. Percy is short for the English name of Percival. Perseus is probably not a common name, except perhaps in Greece.
Medusa was a Greek mythological figure which featured in the legend of Perseus. There is also a "Roman" Medusa. Medusa also featured in Ovid's Metamorphoses. He added more stories about what happened after Perseus slayed her.
Perseus was said to be born in Argos. So back then surnames were not used. So to answer this I wold say his name is Perseus of Argos.
His first name is Perseus (like in the myth of Perseus, Percy is short for Perseus) and his last name is Jackson (since his mother is Sally Jackson and Poseidon doesn't have a last name). His middle name has not been mentioned. Perseus Jackson
