Gorirat Megaton Implode Build: The 300% "Infinite Monkey Nuke" in Palworld 1.0

If you've been following Palworld news since the 1.0 launch, you've seen the clip: a Gorirat walks up to a tower boss, detonates itself with Megaton Implode, and strolls out of the smoke with a full health bar. PC Gamer and AUTOMATON both covered it; the Japanese player testing it posted a ~450,000-damage hit. What those articles don't tell you is how to build it — and the "gorirat megaton implode" build is one of those searches where the content stops at the news headline. This guide goes past it: the mechanics, the four ways to get Heavily Armored, the multi-generation breeding chain that puts Megaton Implode onto a gorilla, and the honest math on whether it's worth it.

Why This Build Exists: The 1.0 Passive That Broke Self-Destruct

Megaton Implode is a Neutral active skill with 1,200 power on a 60-second cooldown — one of the hardest single hits in the game after the 1.0 buff raised it from 500. It has exactly one problem: it incapacitates the user. One shot, then you're reviving at the Palbox. Historically, that made the move a meme.

Then 1.0 shipped a Rainbow-tier passive called Heavily Armored — a single line of text: "Immune to explosion damage." It nullifies self-inflicted explosion damage from Implode, Megaton Implode, Radiant Barrage, and Bee Quiet. Your Pal detonates at full power and its own health bar doesn't move. The only real limiter left is the 60s cooldown.

Why Gorirat Specifically

The "infinite monkey nuke" (a name from the community thread that started this) stacks three things on top of the basic trick:

1. Gorirat is Neutral-type, so Megaton Implode gets STAB — the same-type attack bonus.
2. Full-Power Gorilla Mode, its partner skill, temporarily boosts its attack by +75% at rank 1 up to +300% at rank 5 (buffed from 200% in pre-1.0). Three hundred percent on a 1,200-power STAB move.
3. Hooligan, its fixed innate passive, adds another +15% attack on top (at the cost of −10% work speed, which is irrelevant on a combat Pal).

Gorirat's base stats back it up: HP 90, melee attack 110, defense 90, and its exclusive Ground Pound (Lv 15) is a fine filler between detonations. It also has 305 valid parent pairs in the current breeding table, which matters for the chain section below. Wild spawns sit in the early grassland zones (11–20) with the Mountain Stream Grotto (22–25) as the best dungeon source — so sourcing the species itself is easy.

Getting Heavily Armored: All Four Routes

The passive is the bottleneck — everything else is deterministic. Four ways to source it, from least to most control:

1. Catch wild Pals. Every capture rolls up to four random passives, and the 1.0 regions drop Rainbow-tier passives more often. Volume-farming the World Tree area works; it's just slow and random.
2. Pal Surgery Table implant. Unlock Technology 38, buy a Disposable Implant: Heavily Armored from a Bounty Officer for Bounty Tokens, apply it to any Pal. Zero RNG, level-gated.
3. Breed it across. Once any Pal carries Heavily Armored, chain-breed it onto whatever you need. Inheritance odds: ~73% when both parents have it, ~31% with one parent, ~2% as a random mutation. Keep the parent pool clean.
4. Mutation eggs. Rare chance on any hatch; treat it as a bonus, not a plan.

Route 2 is the pragmatic answer for most players: deterministic, and the implant puts Heavily Armored directly onto your Gorirat line without generations of RNG.

The Hard Part: Putting Megaton Implode on a Gorirat

Megaton Implode cannot be taught with a Skill Fruit, and Tocotoco (Paldex #53) is the only Pal that learns it naturally — at level 22. Getting the skill onto Gorirat means breeding it through the chain: breed a Tocotoco that knows Megaton Implode with a compatible parent to produce an intermediate Pal that inherits the skill, then keep breeding forward until you land on Gorirat. In practice that's a 3–4 generation chain that depends on which intermediate species sit at the right CombiRanks in your Palbox.

This is the step that separates a working build from a news headline — and the reason the naive advice ("just breed Tocotoco with Gorirat") fails: the two species' ranks don't resolve to a direct pair in the 1.0 table for most players' stock. A deeper walkthrough of the Heavily Armored mechanics and the Tocotoco bomb lives in our Infinite Bomb breeding guide.

Passive Loadout and the Rank-5 Math

Four slots, one locked by the build:

If Immortality is out of reach (it only drops from Alpha Necromus), sub in Musclehead or Ferocious — you'll lose a bit of sustain, not the combo.

Hitting the +300% cap costs 116 Gorirat condensed into the parent (rank 5 partner skill). The damage stack then looks like: 1,200 power × 1.5 (STAB) × 4.0 (300% gorilla mode) × 1.15 (Hooligan) × 1.3 (Savior) — before support Pals. Ribunny's Happy-Go-Lucky adds another +20% Neutral attack per condensed rank while benched; four ranked Ribunny = +80%. The Japanese testing that went viral stacked most of this and recorded hits around 450,000 damage.

The Honest Math: When It Wins and When It Loses

• One-shot burst: nothing in the current patch beats a rank-5 Gorilla Mode Megaton Implode for deleting a single target.
• Sustained DPS: the 60s cooldown is the ceiling. Over a long fight, a properly built Bellanoir Libero with Nightmare Bloom out-damages it — the gorilla wins the screenshot, the siren wins the boss kill.
• Practical role: tower bosses, one-shot challenges, and anything you can kill inside one detonation window. Not your general raid DPS.

So: build it because it's fun and it deletes bosses — just don't put it on your farming team.

The Efficiency Bottleneck (and the Tool I Ended Up Writing)

The chain-breeding step is where the build dies for most people. You need to trace which intermediate species actually exist between Tocotoco and Gorirat in the 1.0 table, confirm you own the right genders, and keep Heavily Armored + Megaton Implode alive across every generation — all while a single wrong hop resets your passive pool. Doing that by hand against a 41,000-cell breeding table is an evening of spreadsheet work per attempt.

I wrote a small solver called PalForge (palbreedingcalc.com) to handle exactly this. You drop your level.sav into it, it reads your actual Palbox locally in the browser, and it lays out the shortest multi-generation chain from the Pals you already own to Gorirat — flagging which steps must carry Megaton Implode and Heavily Armored, with per-egg inheritance odds at every hop. Free, 100% client-side, no uploads.

Honest limitations: it works from your save file only, the UI is basic, and it can't force RNG — it tells you the odds, not the outcome. For one-shotting bosses it also can't help you farm Alpha Necromus for Immortality; that part is still a grind. But it turns a multi-hour route-planning session into a 10-second check, and that's the part that used to stop me from finishing builds like this at all.

FAQ

Can you get Megaton Implode on any Pal?
Only by breeding — it's not teachable via Skill Fruit. Tocotoco is the sole natural learner, so every Gorirat with the skill traces back to a Tocotoco breeding chain.

Does Heavily Armored protect against Megaton Implode self-damage?
Yes — that's the entire basis of the build. The immunity covers all explosion self-damage, including Radiant Barrage and Bee Quiet.

What level does Gorirat's Full-Power Gorilla Mode reach 300%?
Rank 5. It scales +75% / +115% / +165% / +225% / +300% at ranks 1–5 (buffed from 200% pre-1.0).

Where do I get Gorirat?
Wild spawns in the early grassland zones (around level 11–20), the Mountain Stream Grotto dungeon (22–25), or breeding — it has 305 valid parent pairs in the 1.0 table.
