The Smoke between worlds. A marvel/DC fanfiction

A.N: this is my first fanfic, so please excuse of the characters are a little bit OOC. And my spelling sucks. So yeah. Also superman \wonder woman is Canon.
Chapter one: 
The justice league was fighting robots, and none of them were happy about it. It was FIVE freaking am, Batman has just gotten back from patroll and fallen into his bed when he got the call. Wonder woman had driven her invisible jet into a robot as she flew to locationlocation, and green lantern had to come in from mars. For robots. Stupid robots. 
Admittedly, they were pretty nice robots, thought batman. He couldn't figure out where they came from, though: there was no recognisable brand. The words: stark industries flowed across the arm of a robot as it few by, though the words were almost hidden by another, larger logo that read, shield. What is shield? Thought batman. 
"Hey BATS!" Yelled berry allen, the flash,
" are you gonna HELP or just stare off into space? "
Batman might have actually growledgrowled, but he started fighting none the less. In twenty minutes the remaining robots were reduced to rubble. The justice league stood around the decapitated robots, thinking. 
"Who could have done this?"
" was it lex luthor? "
" no! Look at the side,it says shade."
" it says shield. "
"Oh."
" who is Stark? "
"Can I go home now?" Everyone looked at the flash. Then the plot gods decided to answer the second to last question. The ground they were standing around, began to glow. . .
Chapter 2:
A bright flash of light illuminated the clearing, but as soon as it appeared, it was gone. Leaving seven people in its wake.
The looks on their faces resembled wild animals.  six of the seven circled around a thin man,  in battered clothes, cuts all over his body.
hostage. They have a hostage.
That's when superman shot a laser at the man in the middle of the pack. It was barely blocked by a red white and blue shield.
