Soppo Build in Girls' Frontline 2

Soppo is the playable return of M4 SOPMOD II. She is an Elite AR Sentinel and the first Doll who deals Freeze and Burn as a dual kit: tile control, Agile Combat-style repositioning, and AoE. She is not Resonance. She is not OTs-14 with a paint swap. Targeted Procurement for her is 17 September 2026 through 7 October 2026. Signature AR is Sky-Shattering Howl (also listed as Skysunderer’s Howl). Outfit is Redline Racer.

This page is the combat build. Banner clocks and skip math live on Soppo Banner and current banners. Pity: gacha and pity. Parent hub: Dolls. Tile fusion: combat and tiles. Priority vs other names: who to pull.

V0 is the practical copy. Signature helps tile uptime; it is not the entry fee if the Doll herself is the hole.

Forms, tiles, and the rotation

She starts in Freeze (Hound Form). Basics and several actives deal Freeze until she switches.

• Mad Dog Form turns those hits into Burn and paints incineration tiles instead of frost.
• S1 is the AoE / tile skill. Almost everything except her basic is area damage.
• S2 is the switch into Burn. In Freeze it is not a damage button; it wants a Burn or Freeze tile to stand on.
• S3 is the switch back toward Freeze and is Freeze-only damage.
• Prey Mark (community S0 shorthand) stacks when she uses S1 or S2 and feeds S3. V0 generates a handful of stacks per turn; higher copies add more.

She wants Burn and Freeze teammates so Monophase and Multiphase fusion happen on purpose. Burn + Freeze is Smoldering Suspire. That is the Tile Transformation combo this kit was built to abuse. Do not overwrite her floor with a random Hydro paint.

Stat priority follows other Sentinel carries: Attack Boost > Crit DMG > Attack > Crit Rate. Attachment set: Freeze Boost or Burn Boost depending on the form you live in for the map; Phase Strike is the lazy universal. Physical Boost does not apply.

Soppo character PV and dual-element kit

Keys, copies, and Sky-Shattering Howl

Load mobility and single-target Keys the same way you would on an AoE Sentinel who still has a boss button. Full Key philosophy is on weapons and builds. Do not 160 a second copy until attachments and Helix on V0 are finished.

Copy	What you actually get
V0	Dual forms, tiles, AoE loop. Practical stop.
V1–V2	Stack generation and uptime. Spend only if she is the account carry.
V5–V6	S3 consume / CI tricks. Whale / endgame.

Sky-Shattering Howl is her Elite AR on a separate weapon banner. Weapon pity is not Doll pity. Outfit Procurement for Redline Racer is a third counter. Pull the Doll first. A V0 Soppo on a substitute AR will outperform a signature sitting on an empty slot.

Redline Racer does not change Keys. Springfield’s Stirring Mermaid and other Part 2 skins ride Outfit Procurement; some tickets drip free. None of that is a reason to convert Collapse Pieces the night before if you still need the Doll.

Teams she actually enters

Staff her on a Freeze or Burn core from team comps, not as a fifth random portrait on a Hydro map.

• Freeze: Soppo + Makiatto or Robella + Suomi/Alva. Robella is a Reunion Oath / standard-era piece that plays with her ice; she is not mandatory if Makiatto is already invested.
• Burn: Soppo + Qiongjiu / Vector + a Burn Support (Sharkry, Ksenia). Mad Dog wants friends on the floor.
• Dual-tile: the point of the kit. Bring one Freeze painter and one Burn painter so Smoldering Suspire is intentional.
• OTs-14: Resonance can sit as a fifth if you already own her. She does not replace Soppo’s tiles.

If the weakest link is “I have no Freeze Support,” Reunion Oath may print Suomi. If the weakest link is “I have no Burn engine,” Qiongjiu from standard still exists. Do not 160 Soppo to fix a Support hole.

Pull plan in one paragraph

Pity does not carry from OTs-14, Basti, or Voymastina. A 79 on the wrong banner is worth nothing on 17 September. Keep pulling Soppo if dual Freeze/Burn tiles are the account gap and you can finish 80–160. Stop if you cannot fund this 80 and still wanted Resonance last week — that ship closed 16 September. Soppo Banner is the calendar; this page is the kit.

Build the copy you keep: Reports, a substitute AR or Sky-Shattering Howl, one elemental set, then stop shopping. The Commander who finishes V0 Soppo on a real Freeze or Burn team will get more fights out of dual tiles than the Commander who owns Redline Racer and an empty Helix.
