Skull Barrier
      When Skull Man is defeated, Mega Man gains the ability to use the special weapon Skull Barrier. The following is a very detailed list, in alphabetical order regardless of game, of all the enemies that can be attacked with Skull Barrier. Along side the list, is how many (if applicable) shots it takes to destroy the listed enemies with this special weapon. There are two games that feature the Skull Barrier: Mega Man 4 and Mega Man III. Unless specified otherwise, the default game this list is referring to is Mega Man 4. Enjoy! (TIP: Press CTRL+F to search for a specific enemy)
