i know very very very little about marvel aside from having watched most of the movies + daredevil and i was wondering, do dc superheroes exist in any way in the marvel universe??

i mean in terms of like, would anyone ever say "___ is your kryptonite" like would foggy ever say that to matt or does the marvel universe have absolutely no reference/knowledge to/of the dc universe?? i mean as far as i'm aware they don't exist as actual people but like do they exist in comic/character form?? could foggy have read superman/batman comics growing up??
