Raids are special battles than can only be undertaken by Leagues and do not consume Stamina. Currently, the "Brainiac: Collector of Worlds" Raid requires the players in a league to defeat 5 bosses, including 4 sub-bosses: Boss Gorilla Grodd, Boss Doctor Fate, Boss Scarecrow, Boss Captain Cold, and finally Boss Brainiac who has 4 phases and can only be attacked after the 4 sub-bosses have been defeated, but the 4 sub-bosses do not have to be defeated in order.

The raid has to be funded by the league, through donations of members. Once started by an officer, the raid will last 3 days.

Each boss has a huge amount of health, 3 modifiers, and is immensely difficult to defeat in one go by a single player. Instead, damage dealt to bosses will accumulate; every player can fight in the raid 3 times, done by up to 30 members (max number of players in a league). Each boss also has a "weakness" to three certain heroes; if they are on your team, you gain different team-wide bonuses against that boss (this does not change between raids or difficulty changes). For raid I-IV, each character you own can be used once per day (max 3 times per raid). For raid V and VI, each character you own can only be used once per raid.

When a league defeats each raid boss, rewards are granted to every member; additionally, upon completing a raid there is a rank reward that depends on how well the player ranks against other league members in terms of damage dealt to the bosses. This will always include League Credits; other possible rewards include hero shards (including League exclusives), level 30, 40, or 50 gear.

  • Despite Boss Scarecrow having Horrific Scarecrow's appearance and pausing will show Scarecrow's passive, neither passives are active during the boss fight against him.
