Tony didn't dare leave the roof, or Obadiah would immediately chase after him, and it would be meaningless to detonate the electric generator.
Pepper, however, still didn't make a move. She looked conflicted. "No, I can't."
Tony could only say emotionally, "Trust me, okay? We don't have… Huh?" He suddenly stopped.
Pepper, who was below, immediately tried to look at the transparent ceiling, only to see a black figure that was much smaller than Iron Monger standing where he had been, but Iron Monger had disappeared.
She exclaimed in surprise, "Batman?"
Tony, who was confronting Obadiah on the roof, had the clearest view as a spectator. He saw everything clearly.
Just as he told Pepper to take action, Batman's ghost-like black figure emerged from the side of the roof and silently glided behind Iron Monger. He grabbed Iron Monger's arm that was firing from behind and threw the colossal creature down to the ground below.
