Undertale Soul OPs 2 Role Tier List
Best Attack, Defense, and Support characters when six souls are on the line.
Co-op in Undertale Soul OPs 2 breaks down into three practical roles even though OyunKlavuzu does not always label them in-menu: Attack (delete waves and bosses), Defense (protect souls and absorb pressure), and Support (buffs, healing, perks, and aura control). With five players guarding six souls, lobbies that cover all three roles clear higher waves than five duplicate DPS picks. This community guide ranks the best characters per role for soul defense—not 1v1 duels.
Use this page alongside the overall tier list, starter rankings, and Team Comp Tool when planning pub queues or friend stacks. Rankings assume average coordination; organized groups can bend the rules with perk stacks from badge characters.
Attack role — kill threats before souls chip
Attackers prioritize DPS, wave clear, and boss phase burst. Souls still die if attackers face the wrong direction, but the role’s job is to remove enemies fast enough that Defense never hard-locks.
S tier Attack picks
- Undyne (starter) — Best free Attack; spear lanes protect souls indirectly while melting health bars.
- Galaxy Sans (tier unlock) — AoE pressure for clustered spawn points.
- Gaster Sans (tier unlock) — Burst windows for boss telegraphs; pairs with Beat Gaster strategies.
- Dust Sans (gamepass) — High skill ceiling carry; dominates when the player knows i-frame timing.
A tier Attack picks
- Sans (starter) — Reliable ranged DPS for learners.
- Fresh Sans (tier unlock) — Mobility-heavy harasser.
- Cross Sans (gamepass) — Hybrid burst with self-sustain between combos.
- Jevil (tier unlock) — Chaos patterns overwhelm waves if souls stay centered.
B tier Attack picks
- Papyrus (starter) — Control-heavy; Attack rating rises when a second DPS follows up.
- Asgore (starter) — Melee DPS with Defense lean; Attack tier only when souls are already covered.
- Reaper Sans (gamepass) — Spiky burst cycles; downtime hurts long defend phases.
Attack tip: In pub lobbies, two Attack mains is ideal; a third Attack without Defense support is how souls hit zero at wave twelve.
Defense role — souls are the win condition
Defenders sit between threats and six souls, using HP, shields, taunts, or zoning to reduce chip damage. Defense wins co-op when Attack is strong but undisciplined.
S tier Defense picks
- Asgore (starter) — Natural body-block tank for new players.
- Toriel (starter) — Lower DPS but strong zoning in full support comps—not solo carry, excellent Defense when paired with S-tier Attack.
- Dream Sans (tier unlock) — Support-Defense hybrid with team protection tools.
A tier Defense picks
- US Papyrus (tier unlock) — Bone walls and ally positioning help.
- Frisk (gamepass) — Flexible kit can pivot Defense in clutch phases.
- Underfell variants (tier unlock) — High risk melee Defense; reward good spacing.
B tier Defense picks
- Outertale skins (tier unlock) — Moderate stats; better for flavor runs.
- Badge tanks with Regeneration — See Dio perk routes on badge roster members.
Defense tip: Stand between souls and the spawn vector for the current wave—not chasing kill icons on the minimap.
Support role — perks, auras, and team tempo
Supports buff allies, apply debuffs, or run perks that multiply team value: Echoing Shadows → Corrupted Presence, Unnerving Aura, DJ Stand, Zapper, event perks, and more. One strong Support often equals half an extra Attack in effective DPS.
S tier Support picks
- Dream Sans — Buff windows and soft Defense; staple in five-stacks.
- US Papyrus — Ally enhancement and zone control.
- Echoing Shadows (badge) — Corrupted Presence aura shifts team damage profiles.
A tier Support picks
- Papyrus (starter) — Entry-level Support before US Papyrus unlock.
- Frisk (gamepass) — Adaptable utility for players who read fight pacing.
- Dio (badge) — Regeneration sustain lengthens Defense windows.
- Quack (badge) — Meme pick with niche perk synergy in casual lobbies.
B tier Support picks
- Event-only supports — Strong during events but power varies after banners end.
- Zapper / DJ Stand perk carriers — Situational; shine when the lobby stacks compatible auras.
Support tip: Stack perks intentionally—random badge picks without reading Perks overview wastes aura slots.
Sample five-player comps

Frequently Asked Questions
Quick answers for Undertale Soul OPs 2 players.
What roles exist in Undertale Soul OPs 2 co-op?
Players organize around Attack (damage), Defense (soul protection), and Support (buffs, perks, utility). The game does not force roles, but soul defense lobbies succeed when all three are covered.
How many Attack characters should a team bring?
Two Attack mains is the pub-queue sweet spot. Three Attack picks without Defense or Support often fail when rush waves target souls directly.
Is Toriel Defense or Support?
Both in practice—she zones for souls (Defense) with lower damage (not Attack). She ranks C-tier as a starter carry but A-tier as a dedicated Defense slot in coordinated teams.
Which perks matter most for Support role?
Corrupted Presence from Echoing Shadows, Regeneration from Dio, Unnerving Aura, Zapper, and DJ Stand are common picks. Read the perks page for patch-specific stacking rules.
Do gamepass characters fill all roles?
Frisk flexes Support and Defense; Dust Sans and Cross Sans lean Attack; Skip Normal and Faster Lobby are not combat roles—they are quality-of-life purchases.
