Titans / Young Justice: Graduation Day #3 (2003)

Part Three: Recessional
The Titans and Young Justice battle the Superman robot, which has already killed Omen, but fare poorly against it. Troia fights it to a near standstill, but is killed by a burst of heat vision through her heart. The robotic life-form is able to complete the shut-down of the Superman robot before shutting down itself. At Troia's funeral, attended by many heroes, the leaders of both the Titans and Young Justice disband the teams. Meanwhile, elsewhere, Donna Troy begins a new life, facing the prospect of battle like the Amazon she is.
