At least these were legitimate fights and not as farfetched to be a discouragement against fanboys. I'm iffy about the Nightcrawler battle as teleporting still sometimes take some energy out of him and he has to get a good jump on him too (i.e. Sebastion Shaw isn't exactly the fastest, but he was able to tag him). The others, Batman has a decent chance especially when he does have a utility belt and this isn't just a required one on one fist fight. Also, he's faced superior fighters than him and still won (i.e. Lady Shiva).
