Fighting Lion

Fighting Lion is an exotic Grenade Launcher in Destiny 2. It was designed by Wei Ning.

Gameplay
Unlike most grenade launchers, which are power weapons, this one goes in the energy weapon slot. Fighting Lion's main perk is that when it strikes an enemy, quickly killing an enemy after will generate and reload another shot for the Fighting Lion.

Trivia

 * The Fighting Lion is considered by the community to be the worst exotic weapon in the series due to its exotic perk having very limited use, until it’s mechanics were revised in Curse of Osiris.
