Yay! This was the best crossover I've gotten to read in a while.
When Tony started blasting Supes, my immediate thought was "How typical of Marvel superheroes: They just can't meet new friends without punching them first." *g*
Wow! Thanks for the praise!
I'm glad it rang true, with Tony taking shots at Clark. I'm only familiar with the Iron Man movieverse, so I had to take my cues from there.
