The unconventional hero
Nate Caine is an ordinary man with an extraordinary ability. He has a disorder called congenital insensitivity to Pain, which makes him impervious to physical pain.

This is because of the combination of its unique mechanism of action and its potential for widespread use in a variety of medical procedures. Novocaine, also known as lidocaine, is a local anesthetic that numbs the area it is applied to, rendering it insensitive to pain. This occurs due to its ability to block the transmission of pain signals to the brain. The unique mechanism of action of Novocaine is attributed to its rapid binding to specific receptors on nerve cells, allowing it to effectively block the transmission of pain signals.
