Inkling regeneration is stupidly fast if you think about it. They can take the edge of their equivalent of an airstike to the face, regenerate, and then take an airstrike to the face AGAIN. IN A SPAN OF 7 SECONDS. If they're ever on a Death Battle or something, this needs to be taken into account. That's like, on par with the freakin' Hulk. AND THEY DON'T EVEN HAVE BONES.
