Superman shook off the remains of about half the pseudo-Eiffel Tower that used to be standing in front of the Paris, and, making sure not to shower anyone with debris, he rose up into the air and shot off into the desert, back into the fray. He looked down and saw the oncoming mess of what looked like the entire contents of every horror movie out in the last ten years, and he put on more speed.
Hulk, he noticed, emitted a light that was keenly human, even more so than the confusing flexing colors of the dragon. It took a special way of looking, but Superman was the most powerful man on earth, and he had a solid moral compass. He didn't even eat meat. So, he dropped down out of the sky and rather than attempting to fight off both Hulk and dragon, he dropped a boulder scrounged from a canyon several miles off onto the dragon's lower half. It squirmed like a lizard pinned under a shoe, and as the dust cleared, Superman lowered to about the level of Hulk. "Need a ride back to town?"
Back on the strip, the mini Bot flew off to take a scouting position high above the carnage and lingered there on autopilot, sans hologram and without Tony's presence.
