Who was the leader of the Paeonians, a Trojan ally killed by Achilles?

Asteropaeus was the leader of the Paeonians, Trojan allies whom Achilles fought and killed. Homer introduces him in the Iliad as a commander serving with the Paeonian forces on Troy’s side.

Asteropaeus was the son of Pelagon and grandson of the river god Axios, which makes his encounter with Achilles especially significant. As Achilles massacres warriors beside the Scamander, the river god gives Asteropaeus courage to stand against him. Asteropaeus is ambidextrous and throws two spears at once: one strikes Achilles’ shield, while the other draws blood from his forearm.

He is the only Trojan warrior in the Iliad explicitly said to wound Achilles. Nevertheless, Achilles kills him and boasts that his own divine ancestry through Zeus is greater. Later, pieces of Asteropaeus’ armor appear as prizes in Patroclus’ funeral games. The name is also commonly transliterated Asteropaios, the form used by the English Wikipedia article.
