No; Hercules is half-brother and a decedent of Perseus. Perseus and Andromeda had a son Electyron who with Anexo had Alcmene, the mother of Hercules with Zeus. Zeus is a…lso the father of Perseus.

Zeus is the father of Perseus; his mother being Danaë, now the son of Perseus and Andromedea was Electryon who with his wife Anaxo had Alcmene - mother of Hercules, wife …of Amphitryon. Perseus is thus both brother of Hercules by being the son of Zeus, and great-grandfather .

No Persues is the son of Zeus and Danae while Hercules(Properly spelled Heracles in the Greek version) is the son of Zeus and Alcmene. Persues is well known for Slaying the G…orgon Medusa and using her head to defeat the Kraken and save his future wife Andromeda. Heracles on the other hand is best known for his 12 labors. Heracles' actual birth name was Alcides, and it was later changed to Heracles as an attempt by Alcmene to placate Hera and beg forgiveness for Zeus' infidelity.

You're comparing Apples to Oranges. They don't compare mainly because they served different purposes. Both were heroes and both accomplished great feats and both were sons of …Zeus.
