Heroes are characters that a player can choose to play as during Missions. Each belongs to a class, granting varying bonuses. Each hero has individual traits in the form of special perks (passives) and abilities.
Before, there were subclasses that grouped heroes inside the 4 main classes, the perks and abilities were shared between more heroes. As of Season 8, that has been removed.
The number of perks and abilities depends on the individual hero's maximum evolution and level, with all unlocked after the third evolution and attaining level 30. The highest an individual hero can evolve is based on that hero's rarity; all heroes have the capacity to gain all perks and abilities, with evolutions beyond the third continuing to increase stats:
- Uncommon: up to three evolutions
- Rare: up to four evolutions
- Epic, Legendary, and Mythic: up to five evolutions
