Titans / Young Justice: Graduation Day #1 (2003)

Part One: Invocation
Troia has been having disturbing dreams of bloody battle for several months, and is becoming ever more accustomed to them. She and the rest of the Titans meet a corporation called Optitron which wants to sponsor them, basically as a tax write-off; they also extend this offer to Young Justice. Nightwing is very strongly against the idea, but the others see it as a great opportunity. The then encounter a cybernetic life-form which is seeking out others of its kind in order to repair itself. When it interfaces with Cyborg, this is seen as an attack. The robot proves more than capable of defending itself, and by the time it is driven off, many members of both teams are unconscious, though Cyborg is adamant that it did not intend to hurt anyone.
