Season 8 of Marvel Rivals, titled Sins of Alchemax, arrives on May 15, 2026, with Devil Dinosaur as the new Vanguard and a long list of hero adjustments across all three roles. The balance pass leans toward buffs, with most Duelists and several Strategists getting stronger numbers, while Vanguard Deadpool, Invisible Woman, and a few crowd-control kits get trimmed back.
Quick answer: Ten heroes receive buffs (Emma Frost, The Thing, Iron Fist, Star-Lord, Wolverine, Moon Knight, Squirrel Girl, Spider-Man, Rocket Raccoon, White Fox), Mister Fantastic, Phoenix, Mantis, and Loki get mixed changes, and four are nerfed outright (Vanguard Deadpool, Invisible Woman, plus crowd-control reductions on Mister Fantastic and Mantis).
Vanguard changes in Season 8
The frontline sees small durability bumps for two tanks and another damage reduction for Vanguard Deadpool, who has been overperforming since his arrival. Devil Dinosaur joins as a new Vanguard at launch and is not part of the balance list.
| Hero | Change | Details |
|---|---|---|
| Emma Frost | Buff | Telepathic Pulse energy decays more slowly after full charge. Diamond Form and Psionic Seduction damage reduction raised from 20% to 25%. Mind's Aegis reposition cooldown lowered from 3s to 1s. |
| The Thing | Buff | Base health raised from 700 to 750. |
| Deadpool (Vanguard) | Nerf | The Ban Hammer ultimate healing cut from 50/s to 25/s. Dual Desert Eagles single-shot damage lowered from 36 to 34 (standard) and 42 to 39 (upgraded). |
Duelist changes in Season 8
Duelists get the widest spread of adjustments. Most are small quality-of-life tweaks like shorter cooldowns and larger magazines, but Mister Fantastic and Phoenix see reworked tradeoffs that change how their kits play.
| Hero | Change | Details |
|---|---|---|
| Iron Fist | Buff | Jeet Kune Do hits cut Dragon's Defense cooldown by 1.2s (up from 1s). K'un-Lun Kick first-strike damage raised from 35 to 40. |
| Star-Lord | Buff | Element Guns ammo capacity raised from 40 to 50. |
| Wolverine | Buff | Regenerative Healing Factor trigger cooldown reduced from 105s to 90s. |
| Moon Knight | Buff | Moonlight Hook cooldown reduced from 15s to 12s. |
| Squirrel Girl | Buff | Mammal Bond cooldown reduced from 15s to 12s. |
| Spider-Man | Buff | Spectacular Spin damage per Spell Field raised from 13.6 to 15 (total damage over 2.4s up from 408 to 450). |
| Mister Fantastic | Mixed | Stretch Punch damage up from 65 to 70. Flexible Elongation no longer slows enemies, but charge time drops from 8s to 6s. Brainiac Bounce ultimate cost lowered from 3,400 to 3,100. |
| Phoenix | Mixed | Cosmic Flames direct hit damage raised from 50 to 55. Spark mark explosion damage reduced from 40 to 35. |
Strategist changes in Season 8
Support gets the most structural rework. Mantis trades a chunk of her damage amplification for a movement-speed aura, Loki swings further toward healing utility, and White Fox gains a much stronger sustained heal during her ultimate setup.
| Hero | Change | Details |
|---|---|---|
| Rocket Raccoon | Buff | Bombard Mode damage per projectile up from 16 to 17. Repair Mode charges up from 8 to 10. C.Y.A. ultimate cost lowered from 4,300 to 4,000. |
| White Fox | Buff | Fox Form Awakening aura healing massively increased from 25/s to 365/s, while per-hit burst heal drops from 35 to 25. Kumiho Unleashed ultimate ally healing raised from 40/s to 60/s. |
| Mantis | Mixed | Allied Inspiration damage boost reduced from 12% to 8%. New effect adds a flat 100 movement speed bonus to allies. |
| Loki | Mixed | Illusion's Mystical Missile healing ratio raised from 90% to 100%, damage ratio cut from 90% to 80%. God of Mischief ultimate cost raised from 4,300 to 4,500. |
| Invisible Woman | Nerf | Force Physics push distance reduced from 12m to 10m, damage cut from 55 to 50. |
New team-up: Primal Punishment
Season 8 introduces one new team-up ability tying Devil Dinosaur to The Punisher. With Devil Dinosaur as the anchor, The Punisher can mount his back during a fight. While riding, Punisher is restricted to his main weapons and the Scourge Grenade, gains damage reduction, and shares any damage taken and healing received with Devil Dinosaur.
The existing Chilling Assault team-up also receives a radius buff, expanding its area of effect without changing its core function.
How to verify the changes in-game
Once Season 8 goes live, you can confirm the patch is active by checking the season banner on the main menu, which will display the Sins of Alchemax title. Hero stat changes appear under each character's ability tooltips, and the Primal Punishment team-up will be visible on Devil Dinosaur and The Punisher's hero pages under the team-up tab.
Full patch notes from NetEase land alongside the May 15 update, and any late tuning adjustments will appear in the in-game news feed. Mid-season changes typically arrive with the Cyclops update in June 2026, so expect another smaller balance pass at that point.
