Marvel Tōkon Datamine: Rocket Raccoon DLC Leaks & Spider-Man Dominates CEO 2026

The dust has finally settled on the first major competitive proving ground for MARVEL Tōkon: Fighting Souls, and the landscape of Arc System Works’ ambitious 4v4 tag team brawler is already taking a definitive shape. Since its highly anticipated launch on August 6, 2026, across PS5 and PC platforms, players have been grinding out optimization in the lab, battling the Champion of the Universe in Episode Mode, and testing the absolute limits of the netcode. Over this past weekend, CEO 2026 provided the definitive stress test for the game’s competitive viability—and it delivered spectacular storylines, unyielding meta developments, and a trail of datamined secrets that have the community buzzing about Year 1 DLC.

From SonicFox taking the crown in a tournament fueled by sheer spite to the realization that Spider-Man is practically mandatory at the top level of play, the inaugural competitive chapter of Tōkon is writing itself at lightning speed. Meanwhile, PC players poking around in the Unreal Engine 5 files have unearthed what looks to be our first glimpse at the post-launch roadmap. Here is everything you need to know about the current state of the game, the latest datamines, and how the competitive tier list is shaking out.

The CEO 2026 Aftermath: SonicFox’s Spite Win

With over 1,000 entrants signed up for the game’s first massive offline major at CEO 2026, the stakes were incredibly high for MARVEL Tōkon: Fighting Souls to prove it had the mechanical depth to sustain an esports ecosystem. Any doubts lingering from the July open beta were completely shattered as the Top 8 produced some of the most blistering, high-octane anime fighting game action seen in years.

FGC legend SonicFox ultimately took home the trophy, carving through a bracket filled with killers like Supernoon and Leffen. What makes this victory particularly compelling is the narrative behind it. Early in the beta phase, SonicFox was highly critical of certain mechanics, catching significant flak from the broader community for their blunt assessments. Following the grand finals victory, they didn’t mince words. Speaking to GamesRadar+, the champion stated that this historic first major win was fueled “purely out of spite.”

It’s a classic FGC storyline, but it also underscores a critical reality about Tōkon: the game rewards absolute mastery over its unique systems. To win a major right now, you cannot simply rely on raw offense. You have to surgically manage the shared Vital Gauge, making split-second tagging decisions to preserve your team’s health pool. Furthermore, elite players are proving that optimizing the Assemble Gauge for perfectly timed assists and combo extensions is what truly separates the pros from the casual crowd.

Spider-Man’s Web: The Undisputed King of the Meta

While the tournament produced a variety of team compositions, one character cast a massive shadow over the entire event. According to a detailed breakdown of the Top 23 teams at CEO 2026 compiled by the Reddit community, Spider-Man is heavily dominating the competitive meta. Out of the 23 highest-placing teams, Peter Parker appeared a staggering 18 times.

What makes the Amazing Guardians staple so ubiquitous? The answer lies in his unparalleled versatility. In Tōkon, characters are often drafted to fulfill specific roles, and Spider-Man excels in the two most crucial ones: Leader and Shooter. As a point character (Leader), his web-swinging mobility and unpredictable air dashes make it incredibly difficult for opponents to establish a solid anti-air game. He dictates the pace of neutral, forcing the opposing team to play his game.

However, his true terror lies in his utility as a Shooter assist. Because the Assemble Gauge dictates how often you can call in your teammates, having an assist that provides massive screen control and long blockstun is invaluable. Spider-Man’s projectile assists lock opponents down, creating easy high/low frame traps or allowing a grappler like Hulk to get in for free. Furthermore, his bread-and-butter (BnB) combos are incredibly efficient at building the Skill Gauge. He doesn’t need to spend EX meter to deal respectable damage; instead, he acts as a battery, filling the Skill Gauge so that heavy hitters can tag in and dump Ultimate Skills for the kill.

Spider-Man’s dominance has already completely reshaped the early tier list. Even popular Knights of Doom villains like Magneto and Green Goblin—who saw respectable usage at CEO—struggle to contest Spider-Man’s relentless air-to-ground conversions.

The Datamine: Rocket Raccoon, Classic Costumes, and Battle Passes

While the pros were battling it out in the arena, dataminers were busy dissecting the game’s files, looking for clues about the officially confirmed Year 1 DLC (which promises 4 characters and 1 stage). Over on the r/GamingLeaksAndRumours subreddit, users struck gold, uncovering plain-text references to unannounced content.

The biggest bombshell is the heavy implication that Rocket Raccoon will be joining the roster as a DLC character. While Arc System Works has deliberately kept the post-launch lineup under tight wraps to avoid spoiling the surprise, files explicitly tagging Rocket as a post-launch addition have seemingly slipped through the cracks. If true, Rocket would bring a much-needed zoning and trap-based playstyle to the game, likely synergizing well with rushdown characters who need cover fire to approach. It is important to note that this is community-reported and not yet officially confirmed by Arc System Works or Sony Interactive Entertainment, so treat it as a strong rumor for now.

Beyond new fighters, the datamine also revealed extensive cosmetic plans. Fighting Souls boasts a stunning cel-shaded anime aesthetic, and it looks like the developers are leaning into nostalgia for customization. Files referencing “Classic” and “Legacy” costumes were found for Spider-Man, Green Goblin, Doctor Doom, and Hulk. For Doctor Doom, who currently sports his heavy supreme ruler armor as the leader of the Knights of Doom, a classic comic-accurate tunic would be an instant fan favorite.

The mechanism for delivering these cosmetics appears to be a Battle Pass system, which was also referenced in the datamined strings. Given the game’s structure, introducing seasonal passes tied to the Year 1 roadmap makes perfect sense for long-term player retention.

Execution Matters: Mastering the Ultimate Skill

As the meta evolves and players settle into their primary teams, execution consistency is becoming the primary hurdle for ranked climbers. The visual chaos of a 4v4 tag fighter can make inputs tricky, especially in scramble situations.

For players utilizing leverless controllers, the community is already circulating optimized input methods. HitBoxArcade recently highlighted the input shortcut for Captain America’s Ultimate Skill, “Sentinel Of Liberty.” To execute this devastating super, which costs a significant chunk of your Skill Gauge, the most consistent input on a leverless setup is a smooth Half-Circle Back, then tapping Forward simultaneously with Medium and Heavy attack buttons (HCB, f + M+H).

This type of input buffer is standard in Arc System Works titles, heavily rewarding players who practice clean execution rather than mashing. Understanding these input quirks is essential because dropping an Ultimate Skill in Tōkon doesn’t just waste your Skill Gauge; it leaves you wide open to a devastating four-man punish that will obliterate your shared Vital Gauge.

Squirrel Girl and the Expanding Universe

Finally, amidst the fierce competition and data leaks, the community has also been hunting for easter eggs. One notable discovery shared on Reddit is a background cameo appearance by none other than Squirrel Girl. While she isn’t playable in the initial 20-character roster, Arc System Works has a history of teasing future DLC candidates through background stage elements and story mode cameos. Fans are already rallying, half-jokingly demanding her inclusion so they can spam squirrel assists on the competitive stage.

As MARVEL Tōkon: Fighting Souls transitions from its chaotic launch window into a stable competitive title, the foundation feels incredibly strong. Between SonicFox pushing the mechanical ceiling, Spider-Man defining the neutral game, and dataminers hinting at a rich pipeline of upcoming content, Arc System Works clearly has a massive hit on their hands.
