Super wars: Iron man
Disclaimer: I don't own Marvel or DC.
Iron man was flying back to his house. He had just defeated Ultron and wanted to rest but nobody would let him sleep as SHIELD called him and asked him to use the hulk- buster amour on the Rhino. When he was done with that, Spiderman wanted him to team up with him and defeat the sinister six. When Iron man finally had some rest, he worked on a secret portal. He switched it on and the portal with a figure walking towards Iron man. He thought he was hallucinating when the figure said "Hey, I'm Batman and I'm here to kill you."
As soon as Batman had said the last sentence, Iron man had suited up and was ready to fight. He blasted Batman and blew him up with missiles. He then punched him in the face. This knocked Batman out cold. Iron man shut the portal and contacted SHIELD. He wanted answers and they had to be good.
