Berserk Button: Network will bite, claw, scratch and kick like the devil is you even suggest making her psi-blind. Justified in that without her telepathic powers, she's unable to read, speak, or communicate.
For Cascade, it's even suggesting that she's remotely like her mother, Matriesse.
For Finale, it's the mere thought of getting wet. Believing she had made contact with water literally drove her berserk at one point.
Big Eater: Cruiser's telekinesis is fueled by his body mass.
Continuity Nod: Several for the main DCU, including a Road Trip to Gotham City during the Contagion Storyline, the events of Final Night took place during Network's turn as a Fake Defector, and the events of the Genesis storyline.
Eyepatch of Power: In the final issue, a character sports an eyepatch that she previously hadn't worn. The Sovereigns assumed it was due to an injury in the close quarters fighting they were currently locked in. Turns out it was a gunsight for a Kill Sat.
Fake Defector: Network pretends to be under the Mind Control of the Chimera android, until she reveals that she's merely playing along to rescue an infant telepath from the organization's clutches. Her friends, however, do not take her actions very well.
Kill Sat: The Mir Space Station functions as one in the final issue.
Never Learned to Read: Network. As a telepath, her "language" is based in imagery and not symbols or letters. It's been stated that without her telepathy, she would be incapable of learning spoken or written language.
What the Hell, Hero?: Pretty much everyone's reaction to Network's Fake Defector stint. Network decided she couldn't let the others in on her scheme, for fear it would be discovered, and Cascade took it so hard, she actually left the team for a time.
