Ring Boomerang
      When Ring Man is defeated, Mega Man gains the ability to use the special weapon Ring Boomerang. The following is a very detailed list, in alphabetical order regardless of game, of all the enemies that can be attacked with Ring Boomerang. Along side the list, is how many (if applicable) shots it takes to destroy the listed enemies with this special weapon (Keep in mind that - Mega Man 4: if Ring Boomerang goes through an enemy, it will come back to Mega Man potentially hitting the same enemy again. This said, amounts listed below are assuming that each hit is one use and in Mega Man IV, Ring Boomerang does not pass through most enemies (some projectiles and small enemies), instead it allows Mega Man to grab drops/items from far away). There are two games that feature the Ring Boomerang as a usable weapon (excluding the "Bridge" and Weapons Archive bosses): Mega Man 4 and Mega Man IV. 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)
