Summary
The Titans work with the Justice League to deal with the catastrophic threat of Starro, who has been unleashed by the alien android Brainiac (with secret collaboration of Slade) to attack Starfire's home planet of Tamaran. As her teammates work with the League to stop the disaster, Starfire gets help from Martian Manhunter to discover how Slade knew so much about her world and she is about to discover a rather unsurprising but very shocking truth about it.
