Marvel Rivals Players Can Finally Complete Final Cerebro Database Chapter Mission For Free Mantis Skin

With the release of Marvel Rivals' second season, the Hellfire Gala, in April 2025, which welcomed two more heroes added to the growing roster, a refreshed in-game Store, and a Battle Pass, there is a few additional new content to explore. Aside from the new map with a couple of Easter Eggs for players to locate, there is a new event, the Cerebro Database, which rolled out in four waves with new missions to complete and rewards to claim.

However, the developer has made things interesting with the Cerebro Database event, in which mission blocks are provided and will be unlocked at specific intervals, and the final wave or chapter has now gone live in-game. The final reward for players to claim upon completing the entire event's missions is a free skin, the Flora Maiden costume, for the Strategist hero, Mantis.

The Cerebro Database event features nine mission blocks that unlock at periodic intervals, during which four chapters of missions will become available to players to complete. The main objective is to "complete missions and form any three lines (row/column/diagonal) to clear the challenge," which, after completing any line, whether it's in a row, column, or diagonally, they'll unlock rewards for each wave or chapter completed.

Each wave or chapter features slight variations in rewards, which include Chrono Tokens, Units, Gallery Cards, and Sprays for specific characters, namely Black Panther, Emma Frost, Namor, and Wolverine. Additionally, it's worth mentioning that the 75 Units bonus will be available to claim for a limited time before disappearing from the rewards tracker from the event's page.

Once all missions for the Cerebro Database event have been completed, they'll immediately unlock the "Mantis - Flora Maiden" costume for their efforts, which players have until 9th May 2025 to complete all remaining missions and claim all rewards. There are a few rumors that the "Mantis - Flora Maiden" costume may be available to purchase from the in-game Store; however, we have no information to verify this as of writing and will update the page once it has been confirmed.
