Prominemt suitor who is the arch-enemy of Telemachus?

The prominent suitor who serves as the arch-enemy of Telemachus in Homer's "The Odyssey" is Antinous. He is the leader of the suitors vying for Penelope's hand in marriage while Odysseus is away, and he is particularly arrogant and aggressive towards Telemachus. Antinous's disdain for Telemachus is evident as he openly mocks and threatens him, representing the opposition to Odysseus's family and legacy. Ultimately, his actions contribute to the tension and conflict that drive the narrative of the epic.
