Unlock + stats + verdict · Updated 2026-07-07
Thermo Godzilla (community shorthand for Thermonuclear) has the highest level gate on the roster and needs a form you likely already own. Punch in your numbers below to see exactly what is left.
TL;DR: Thermo Godzilla fast version
Enter your current level and U-cells, tick off any materials you already hold, and this recalculates exactly how many hours of farming are left.
Gate: Level 65+ required
STILL FARMING
~52.9 hrs left
Breakdown: 45 levels to go · U-cells 1800 short (~12.9h at 140/hr) · materials ~26h remaining.
Total gate estimate from a fresh Level 1 account: ~40 hours (14 level + 15 Thermal Core + 8 Radiant Scale + 3 trial), plus the U-cell farm on top. The U-cell farming calculator covers currency-only planning if you want to isolate that part.
Five-axis comparison against the two other S-tier-or-above picks. Pick a rival to compare against.
For event and boss grinding: Thermo Godzilla's 90 AoE score is the highest of any S-tier-or-above form tracked so far, well ahead of Minus One's 40. Thermonuclear Pulse clears grouped event waves faster than either rival. This is the strongest pick here for pure PvE content.
Four ability slots, same rotation structure as every other kaiju. SULU KAKA does not publish exact damage numbers or cooldowns — these are community-reported and personally timed.
| Slot | Ability | Type | Cooldown | Damage tier |
|---|---|---|---|---|
| 1 | Heat Ray Surge | Ranged | 5s | A |
| 5 | Molten Slam | Melee | 7s | A |
| R | Thermal Vent | Defensive | 9s | C |
| T | Thermonuclear Pulse | Finisher | 16s | S |
Thermonuclear Pulse has the widest hit radius of any Slot T finisher tracked so far — it is the move that makes this form an event-clearing pick rather than a 1v1 duelist. Full slot-by-slot breakdowns for every form live on the moveset guide.
Worth it if you already play Godzilla Minus One regularly and grind events or boss content. The 90 AoE score is the highest of any form tracked, and Thermonuclear Pulse turns grouped event waves into a much faster clear than either Minus One or Destoroyah Form 4 manage alone.
Weaker case if you are a pure PvP player still deciding on a first S-tier unlock. The 55 Speed score is the lowest of the top three forms, which makes it easier to kite and punish between ability windows. Destoroyah Form 4 keeps the higher ceiling in clean 1v1 duels, and Godzilla Minus One is the more forgiving first S-tier investment for most players.
The honest framing: this is a second S-tier-or-above unlock for players who have already cleared the Minus One path, not a standalone first pick. The best kaiju tier list covers where every other form ranks if you are still deciding what to chase first.
Reach Kaiju Level 65, save 1800 U-cells, farm a Thermal Core from the rotating Overload Event (~9% per clear), collect 2x Radiant Scale from Godzilla Minus One boss runs, and clear the one-time Meltdown Trial mission. Budget around 40 hours total from a fresh account, longer if the Overload Event isn't currently active.
Roughly 9% per Overload Event clear based on community tracking across 22 event windows — the lowest drop rate of any material tied to a current unlock path. The event is limited-time and rotates in and out, so the real bottleneck is often event availability rather than the roll itself.
Effectively yes. The Radiant Scale material only drops from the Godzilla Minus One boss encounter, so that form needs to be leveled and farmable first. Thermo Godzilla is a second S-tier-or-above investment rather than a standalone first pick.
It sits a step above the standard S tier on AoE-heavy metrics — its 90 AoE score is the highest tracked so far, ahead of Godzilla Minus One's 40 — but its 55 Speed score is the lowest of the top three forms. It trades mobility for the biggest area-clear ceiling on the roster.
Worth it if you grind events and boss content — Thermonuclear Pulse clears grouped waves faster than Minus One or Destoroyah Form 4. Weaker case for pure PvP mains: the low Speed score makes it easier to kite than Minus One, and Form 4 still has the higher clean-duel burst. It is a strong second S-tier unlock, not the best first one.
Slot 1 is Heat Ray Surge, a ranged beam poke. Slot 5 is Molten Slam, a heavy close-range hit. Slot R is Thermal Vent, a defensive window that reduces incoming damage while venting a portion back. Slot T is Thermonuclear Pulse, a wide-radius finisher and the highest AoE finisher tracked on any current form.
Destoroyah Form 4 has the higher single-target burst (95 vs 90 Damage) and is the better clean 1v1 duelist. Thermo Godzilla trades some of that ceiling for a much wider AoE finisher and better range, making it the stronger pick for event waves and grouped boss fights rather than isolated duels.
