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 is used to disable an enemy's shield, quickly killing said enemy instantly reloads 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.
