I'm Batman! 13 1, 7:17pm

@Rogers
It is even worse /saying/ superman in Swedish, it sounds like the speaker is asking if it would be appropriate to get drunk.

[Swe] "Super man? rädda mig!!"
[Eng] "Getting drunk? save me!!"

[Swe] "Super man? Förbaskade hjälte!"
[Eng] "Getting drunk? Blasted hero!"

I can see why they went with Stålmannen.

Batman would by the way turn into Fladdermusmannen, pronounced Fladder-mus-mannen. Literally "The Flutter Mouse Man"
