Supers in Destiny 2.

Supers define each of the Subclass that Titans, Warlocks, and Hunters use. Supers use the long meter above the melee, class and grenade indicators. It takes several minutes (normally) for a Super to be charged up. If a Guardian collects Orbs of Light that another Guardian produces while using their Super, their own will recharge faster.

Supers fall into 2 categories: Roaming and Burst. A Super like Nova Bomb is a burst super, have a single large expenditure of energy for massive energy. Another like Stormtrance is a roaming super. A roaming super has the Guardian able to travel around an area expending their Super meter to maintain the super and use its special attack.
