Kurt can't hit what he can't see... especially when The Detective can withdraw his presence at will, fading from NC'S sight [ancient mental martial arts tecnique]
Together Batman's 6th sense, strong Chi and advanced training [Batman can dodge arrows blindfolded] allow him to pinpoint Crawlers new location instantaneously
If NC fights like he's fighting Wolverine and he's in the grounds of the X-mansion then N.C: 8-9-10/10
however fights in Gotham NightCrawler: 1-2/10
hate it or love it baby.,
