Marvel Rivals Boss Guide: How to Beat Every Major Boss

2026-06-09·Boss Guides

Key Takeaways

  • Galactus (Season 1 final boss) requires at least 2 hitscan DPS — Hela and Punisher are nearly mandatory for the cosmic ring weak points.
  • Thanos's Infinity Gauntlet phases rotate predictably: Power → Space → Reality → Time → Mind → Soul. Each phase has a specific counter.
  • Doctor Doom's Doombot summons are the real threat, not Doom himself. Kill Doombots immediately or they overwhelm your team in 60 seconds.
  • PvE boss loot is weekly — farm each boss once per week. The drop rates for legendary skins are ~2%.

Galactus (Cosmic Threat — Season 1 Final Boss)

HP: 500,000 (shared across team) Phases: 3 Recommended Team: 2 Vanguard, 2 Duelist (hitscan), 2 Strategist

Phase 1 (100%-70%): Cosmic Ring

Galactus hovers above the map, invulnerable. Six cosmic rings orbit him — these are the weak points. Shoot them with hitscan weapons (projectile heroes like Storm can't hit them reliably).

Each destroyed ring spawns 3 Herald adds (flying enemies). Designate one Duelist to clear adds while the other focuses rings.

Phase 2 (70%-40%): Grounded

Galactus lands. Now he's targetable but also attacks. Key mechanics:

  • Cosmic Stomp: Every 15 seconds, Galactus stomps. Everyone within 20m takes 200 damage. Tanks can survive; others must be outside the radius.
  • World Ender Beam: Targets one player, sweeps across the arena. Hide behind the cosmic debris (pillars that spawn during this phase).

Strategy: Tanks hold Galactus's attention from opposite sides (he turns slowly). DPS focus one leg at a time — destroying a leg staggers him for 5 seconds.

Phase 3 (40%-0%): Desperation

Galactus spawns ALL mechanics simultaneously: rings, stomps, beams, and adds. This is a DPS race.

Save all ultimates for Phase 3. Pop Luna ult for sustain, Groot ult to trap adds, and unload every DPS ult into Galactus's head.

Doctor Doom (Latveria Invasion — Recurring Event)

HP: 250,000 (Doom), 50,000 each (Doombots) Phases: 2

Phase 1: Doombot Army

Doom is invulnerable. 6 Doombots spawn every 30 seconds. You must survive for 3 minutes while destroying Doombots.

Strategy: Kill Doombots AS SOON AS THEY SPAWN. If more than 8 Doombots are alive simultaneously, your team wipes. Dedicate 2 DPS to Doombot clearing, 2 tanks to kiting, 2 supports to staying alive.

Phase 2: Doom Direct

Doom becomes vulnerable. He uses:

  • Force Field: Blocks all damage for 8 seconds. Don't waste ults during this.
  • Lightning Storm: AoE circles on all players. Spread out and keep moving.
  • Doombot Reinforcements: At 50% HP, 4 more Doombots spawn. Kill them first.

FAQ

Q: How often do boss events rotate?

A: Galactus is permanent (Season 1). Thanos returns for Infinity Saga events (~every 3 months). Doctor Doom rotates in monthly.

Q: Can I solo any bosses?

A: No. All PvE bosses require 6-player teams. Use the in-game LFG (Looking for Group).

Q: What's the best boss for farming loot?

A: Doctor Doom (fastest clear, ~8 minutes). Galactus takes 20-30 minutes and the drop rates aren't proportionally better.
