The leak, extracted from Steam achievement data and tied to a larger set of files affecting multiple titles, supplements official information Capcom and partner teams have released in recent weeks.
According to the achievement listings made public in the leak, the complete roster of Robot Masters for Mega Man: Dual Override includes Boat Man, Build Men, Cleanser Man, Cook Man, Jet Man, Sand Woman, Tank Man, and Twinkle Girl.
Twinkle Girl was already announced by Capcom last month; the achievement dump adds the remaining characters and confirms which fan-submitted design took the contest’s top prize.
Capcom had previously named six finalists in the fan design contest tied to Dual Override.
The achievement data indicates that Cleanser Man is the contest winner, and the leak includes an asset that displays the character’s design.
In journalistic terms: Capcom’s earlier finalist announcement is now complemented by evidence in the achievement files that identifies Cleanser Man as the winning entry.
The Steam achievements leak is part of a broader disclosure that has exposed metadata and achievement lists for multiple games.
Among the other titles affected by those leaks is Kingdom Hearts 4, where achievement entries reportedly revealed additional details; outlets covering both stories have linked the two disclosures to the same source of dumped achievement data.
Mega Man: Dual Override’s 2027 launch on Nintendo Switch 2 and Nintendo Switch positions the title for wide exposure across Nintendo’s handheld-console family.
Capcom is the publisher and developer historically associated with the Mega Man franchise, and the company’s promotional schedule has included periodic reveals via Nintendo Direct and eShop listings in past campaigns for Switch releases.
For readers tracking Dual Override, the achievements leak provides the most complete Robot Master roster revealed to date and confirms the fan contest outcome.
Capcom’s official channels remain the authoritative source for final character rosters and launch details; the studio has released select updates and developer interviews about the project in recent months.
