Agamemnon. Agamemnon, king of Mycenae and commander-in-chief of the Achaean army, resembles Achilles in some respects. Though not nearly as strong, he has a similarly hot temper and prideful streak.ut Agamemnonâs pride makes him more arrogant than Achilles. While Achillesâ pride flares up after it is injured, Agamemnon uses every opportunity to make others feel the effects of his. He always expects the largest portions of the plunder, even though he takes the fewest risks in battle.
