The Dark Grenade, also known as the Grenade or Dk.Grenade, is an enemy from Final Fantasy IV. It is the strongest of the Bomb-type enemies, and takes a bit more effort to defeat, but is not much of a threat unless left alone at high HP and it decides to use Self Destruct. They are even more of a threat when in groups, so it is advised to take them out first before focusing on other enemies, or use group attacks. However, a single Leviathan or Bahamut summon is more than enough to dispatch all of them. A good way to defeat them is by using a non-lethal Lightning attack since they will cause a chain reaction that not only destroys the Dark Grenade but also destroys every enemy in the battle.
