Hulk wasn't exactly hard to find. He was, after all, at least twice his usual size.
He'd been legitimately disappointed when all of the monsters just up and disappeared. Lightning meant Thor, though, and he did like Thor. But his friend was busy so he let him do his thing while he -- well, this was boring.
He wasn't new to this. There'd been many fights over the years. These people all expected him to do the fighting bad guys thing and then hand the reins back over to Banner and he was tired of it. Thanos wasn't here, why couldn't he just...you know. Stay out? And there were friends here. He'd already seen many of them and that was a good thing.
And then there was the girl. That had been a surprise. The part of him that was always conscious when Banner was in control knew she existed, but seeing her was odd. But special. Something neither of the men who shared this body had ever expected.
He heard the tiny voice and put down the huge piece of rubble he'd been clearing from a building. What? He could help, too. May as well, there was nothing left to kill. She had the taller yellow-haired one, too. Thor's child. Hmm. Not the rescue team he had expected. "What?" Like he didn't actually know.
