Collaboration, PV and Battle Arena
Edward Elric Is Officially Entering the Battle Arena
The most important confirmation from the first announcement is that Edward Elric will enter the Compass Battle Arena.
Edward is the central protagonist of Fullmetal Alchemist. In the original story, he becomes a State Alchemist at an exceptionally young age and earns the Fullmetal Alchemist title after losing parts of his body following a failed human transmutation.
His established fighting style combines alchemy performed without drawing a transmutation circle, physical combat and the automail attached to his right arm.
Conceptually, that gives Edward several traits that could fit a game built around movement, skills, direct combat and area control.
That should not be treated as confirmation of his actual mechanics, however. Until Compass publishes a detailed hero breakdown, his role, statistics, skills and playstyle remain officially undetailed.
Edward's Gameplay Details Remain Unannounced
The collaboration PV and announcement confirm Edward's inclusion without providing a complete gameplay breakdown.
There is currently no verified official information identifying him as an Attacker, Gunner, Tank or Sprinter.
His Hero Action, Hero Skill, passive effects, movement parameters, attack range and card interactions also remain unexplained in the main material currently available.
The same distinction applies to his voice. Romi Park voices Edward in Fullmetal Alchemist: Brotherhood, but this article does not assume a specific voice implementation in Compass until the game itself confirms it.
Those details may arrive through a dedicated hero introduction or in-game information once the collaboration opens.
The PV Is the Main Reveal Material
Compass accompanied the announcement with a dedicated collaboration promotional video on YouTube.
The video serves as the primary visual material connecting Fullmetal Alchemist with the Compass Battle Arena while confirming Edward's involvement.
Because the crossover announcement and video are the central subjects of this article, the 12-image media grid uses frames from the official PV rather than generic Compass store screenshots.
Google Play remains included as the primary mobile-store embed for the game itself.
Compass Packs 3v3 Battles Into Three Minutes
Compass is a real-time online mobile battle game built around three-minute 3v3 matches.
Two teams move across an arena and compete for control points. Players choose heroes with different characteristics while also building decks from skill cards to adjust their tactics.
Victory is therefore not based solely on defeating opponents. Positioning, area control, hero composition and card usage can all shape the outcome of a match.
That system gives crossover heroes the opportunity to function as more than cosmetic appearances. Previous collaboration characters have joined the game's actual roster, although Edward's specific implementation remains unannounced.
The Collaboration Arrives During Fullmetal Alchemist's 25th Anniversary Year
The timing is also notable because 2026 marks the 25th anniversary of Fullmetal Alchemist.
Square Enix officially identifies 2026 as the work's 25th anniversary year through projects including the Fullmetal Alchemist x Daemons of the Shadow Realm exhibition.
Hiromu Arakawa's manga began in 2001 and eventually concluded across 27 collected volumes. Square Enix currently states that the series has surpassed 80 million copies in worldwide circulation.
Fullmetal Alchemist: Brotherhood aired from 2009 to 2010 with BONES handling animation. Romi Park voices Edward, while Rie Kugimiya voices Alphonse Elric.
The Compass crossover therefore joins a broader year of new Fullmetal Alchemist activity tied to the franchise's anniversary.
Characters, Cards and Event Duration Are Still Incomplete
Although Edward is confirmed, several major collaboration details remain unanswered.
The verified main announcement does not yet confirm whether Alphonse Elric, Roy Mustang, Riza Hawkeye, Winry Rockbell, or other characters will appear as heroes, cards, costumes or another form of content.
The complete collaboration-card lineup has not been detailed, and neither has any costume lineup for existing Compass heroes.
An end date is also absent from the main announcement. September 28 is therefore treated only as the confirmed starting date, without inferring the event's duration from earlier Compass collaborations.
Why This Matters
1) Edward is entering the Battle Arena rather than appearing only in promotional art
The official announcement explicitly states that Edward Elric will participate in the Compass Battle Arena.
2) Edward's established combat style creates interesting possibilities
Alchemy, automail and close-range combat offer several potential directions, although the official mechanics still need to be announced.
3) The crossover arrives during a major Fullmetal Alchemist anniversary year
2026 marks 25 years since Hiromu Arakawa's manga began in 2001.
4) A substantial amount of collaboration information remains open
Edward's role and skills, cards, costumes, additional characters and the event's end date have yet to be fully disclosed.
