Marvel Tōkon: Fighting Souls Guide: How to Master Carnage’s Necrosis Loop

Daniel Carter11/08/20264 min read

Carnage has crashed into Marvel Tōkon: Fighting Souls, and Arc System Works’ official character guide for the symbiote killer confirms his kit revolves around inflicting a stacking debuff called Necrosis before cashing it in with tendril follow-ups. Marvel Tokon: Fighting Souls is available to play starting today, and Carnage’s character guide video has been released that details how to play the fighter. Despite his monstrous design, the villain is rated as one of the more approachable characters on the launch roster.

Carnage is said to be among the easiest fighters to play in Marvel Tokon. His ease of usage rating is just as high as Captain America and Hulk’s, despite some important caveats that need to be understood in order to properly play him. That accessible-on-paper, tricky-in-practice profile is exactly why a dedicated guide was needed before players started dropping him into ranked matches.

Necrosis and Parasite Fang set up Carnage’s damage

Carnage’s unique mechanics “Necrosis” and “Parasite Bomb” are fundamental to making his kit work. The primary way to apply that debuff is Parasite Fang, described by Shacknews as a long-range strike that affects the enemy with Necrosis on hit or block, with a standing or crouching low version available on the ground to swing straight ahead at the enemy.

Independent outlet DashFight corroborates the mechanic’s core loop, noting that Carnage is shaping up to be an extremely aggressive character built around the Necrosis state, where infecting an opponent with one of his specials lets subsequent H attacks deal extra damage on hit or block while further attacks refill the Necrosis gauge. In other words, once the debuff lands, Carnage’s heavy attacks start punishing guards as hard as they punish whiffs.

Parasite Bomb converts pressure into chip damage

Fighting game fans familiar with M. Bison in Street Fighter 6 will recognise how Carnage’s Parasite Bomb operates. Landing Necrosis with Parasite Fang and then following up with a special or the Unique button turns ordinary block strings into a source of guaranteed extra damage, rather than a purely offensive gamble.

That’s also why the character is described as rewarding patience rather than button-mashing. There are important caveats that need to be understood in order to properly play Carnage, and skipping the Necrosis setup leaves him with multi-hit normals that rack up combo counters without dealing serious damage on their own.

Carnage anchors the Knights of Doom villain team

Carnage wasn’t a solo reveal. Sony’s PlayStation Blog confirmed him back in June alongside Magneto and Green Goblin as part of a new villain faction, noting that Doctor Doom, voiced by SungWon Cho, leads the Knights of Doom, which bring three powerful newcomers to the roster: Magneto, voiced by James Arnold Taylor, Green Goblin, voiced by Steve Blum, and Carnage, voiced by Kellen Goff.

EventHubs’ coverage of that same reveal detailed Carnage’s gameplay identity ahead of launch, reporting that Carnage can use his symbiote powers to stretch and transform his body with crazy range, and has a “symbiote-infested” state that boosts his abilities and drains health even from guarding enemies. That framing lines up with the finished game’s Necrosis system now available to every player.

The trade-off: no full-screen projectile, sluggish neutral

Carnage isn’t without weaknesses. Shacknews’ hands-on breakdown of the character warns that his attacks are disjointed and multi-hitting, his gimmick has to be applied to get to his full potential, and his movement can feel sluggish outside of his specials, which pose risks if used in the wrong place at the wrong time. That risk-reward tension is precisely what separates a competent Carnage player from a great one.

The character also lacks the safety net that many of his teammates enjoy. He doesn’t have a full-screen projectile, meaning he can be pinned down in a fireball fight against the characters that do. Against zoning-heavy fighters like Magneto or Iron Man, Carnage players will need to close distance carefully rather than trade at range.

Notably, Carnage wasn’t part of the game’s Open Beta test window, which ran before launch, so he was one of the characters unavailable during that period, meaning most players probably know more about the other combatants than Carnage at this point. That knowledge gap is exactly why character-specific guides like this one are drawing attention in the fighter’s opening days.
