The frame above is from the very beginning of the new Netflix Daredevil
series (not to be confused with the Affleck movie
) where a young Matt Murdock is blinded after being hit by a truck and exposed to toxic chemicals that were being transported on it. Note the open manhole cover in the background, with the toxic chemicals spilling down into it. In the original (non-Marvel, BTW) Teenaged Mutant Ninja Turtles
comic books, the Turtles received their powers during the same incident as Daredevil, from the same chemicals.
