Porygon Labs — Pokémon Champions VGC Damage Calculator & Team Builder

v1.3.1

Stat panel reflects boost stages and held-item multipliers live — Choice Scarf shows the 1.5× speed, Eviolite shows the bumped Def/SpD, stage boosts/drops update the displayed numbers. Hover for the breakdown.
Pin Missile, Fury Attack, Spike Cannon, Comet Punch, Double Slap, Arm Thrust, Fury Swipes, Barrage, Tachyon Cutter, Double Iron Bash, Gear Grind, Dragon Darts, Bonemerang, Double Kick now all calc as multi-hit moves.
Protean / Libero is now a 3-state toggle: natural STAB (default — only same-type moves get STAB), all STAB (green — Protean activated to match this move), no STAB (red — Protean already locked the mon to a different type). Click the ability to cycle.
Form-prefix imports normalize: Eternal Floette-Mega, Alolan Marowak, Galarian Articuno, Hisuian Zoroark etc. all resolve to their canonical Showdown names.

v1.3.0

Accounts: register, log in, log out, password reset by email, delete your account.
Saved teams: name, tag, regulation, notes — filterable by tag and reg in the load modal, with name uniqueness enforced per account.
Match history per team: win/loss/tie, opponent name, archetype, your lead, and the opponent's full team layout (leads / brought back / didn't bring). Cursor-paginated with a record summary.
Saves and deletes are optimistic — match and team modals close immediately; the change shows up before the server response lands, with a toast and revert if it fails.
Custom autocomplete dropdowns for tag and archetype fields — themed to match the modal, no more browser autofill speech bubble.
Faster repeat loads: static datasets (moves, items, abilities, full move data) cached in localStorage per release; auth identity cached in sessionStorage so the header paints instantly on a returning tab.
Server cache headers + ETag on data endpoints — unchanged versions return 304 with no body, killing the re-download on every page load.
Search is now separator-insensitive: "u-turn" finds U Turn, "Will-O-Wisp" finds Will O Wisp, "Mr. Mime" works with or without the dot.
Password reset page now self-contained — guaranteed dark, themed, and editable regardless of cache state.

v1.2.25

Themed hover tooltips for moves and abilities (replaces the browser's white default; positioned so they don't get clipped by the panel edge).

v1.2.23

Electrify added to Heliolisk and made toggleable — when active, all that side's damaging moves are treated as Electric.

v1.2.22

Added Electrify (Electric / Status) — was missing from the move dataset.

v1.2.21

Blaze / Torrent / Overgrow / Swarm now toggleable for the 1.5× pinch boost.

v1.2.20

Reg MA pastes without SPs auto-fill the curated spread (mega / stance / regional forms included).
Opponent paste no longer drops parsed SPs.

v1.2.19

Move explorer allows up to 8 moves for what-if testing.
Damage table chunks calcs per attacker — large teams no longer render blank.
Round echo: toggle Round on a partner to apply the 2× BP boost.
Hover any move or ability chip for a description tooltip.

v1.2.18

Knock Off no longer 1.5× boosted vs compatible Mega Stones, Primal Orbs, Griseous Orb, or Rusted Sword/Shield.
Protean / Libero toggleable (defaults ON = STAB on every move).
Added Round (was missing — used to read Immune).
Twin Beam now correctly hits twice.
Speed order works past 12 Pokemon.
Paldean Tauros pastes resolve without the -Breed suffix.

v1.2.17

Fixed Freeze-Dry — it now correctly hits Water types for 2× instead of 0.5× (A-Ninetales OHKOs Pelipper again).

v1.2.16

Added Unlock Limit toggle to My Team (same as opponent side — bypass the 6-Pokemon cap).
Random button now seeds 144 top-placing Reg MA tournament teams.
Reg MA random teams show an "EVs not confirmed" notice — tournament pastes don't carry spreads.

v1.2.15

Added drag handle to Pokemon cards — grab the top-left handle to reorder within a team.

v1.2.14

Fixed Multiscale / Shadow Shield halving every hit of multi-hit moves — now only the first hit is halved.
Fixed move search returning no results after opening a shared team link.
Added per-Pokemon Burn and Paralysis toggles — auto-halves physical Atk and Speed (Guts/Facade/Quick Feet respected).
Reg MA usage sample expanded to 3,892 teams across 19 tournaments (through 2026-04-22).

v1.2.13

Fixed Reg MA damage calcs treating opponents as Terastallized — stale isTera state (from a previous regulation or the inline Tera checkbox) was replacing defensive typing and killing super-effective hits (e.g. Whimsicott Moonblast vs Sableye reading as neutral instead of 2×).
Added missing move: Zap Cannon (Electric, 120 BP, 50 acc, 100% paralyze).

v1.2.12

Fixed Protean / Libero not applying STAB — every move from a Protean/Libero user now correctly gets the 1.5× boost (disabled when Tera'd, since Tera locks types).
Fixed Meowstic-F not showing the Mega button — Mega Meowstic is accessible from both male and female forms.
Last Respects now ignores "out" markers — click the move in the damage table to cycle through 0–5 fainted allies and see the damage at each tier.

v1.2.11

Curated SP spread defaults for all 213 legal Reg MA pokemon — replaces the "max attack everything" fallback with thoughtful spreads per species (megas hand-tuned for the mega's role).
Fairy Aura / Dark Aura / Aura Break now actually applied in damage calcs (1.33x to Fairy/Dark moves, inverted by Aura Break).
Aegislash Stance Change implemented — click the ability on its card to flip between Shield and Blade Forme stats.
Liquid Voice now converts sound moves to Water type (Primarina's Hyper Voice / Sparkling Aria / etc.).
Last Respects BP now scales with fainted allies (50 + 50 × N).
New "Single Target" checkbox next to Critical Hit — removes the 0.75x spread modifier for calcs against a single target.
New "Helping Hand" checkbox next to Critical Hit — clearer than the per-pokemon move toggle.
Fixed Never-Melt Ice not applying its 1.2x Ice boost (item name mismatch).
Team exports now include "Level: 50" explicitly — Showdown was treating exports as level 100.
Added 13 missing moves to data: King's Shield, Light of Ruin, Sparkling Aria, Pin Missile, Thunder Shock, Bite, Low Sweep, Thrash, Aurora Beam, Shadow Punch, Magic Powder, Aqua Cutter, Rage.
Patched 53 missing moves into pokemon learnsets from tournament usage data — Drampa now has Earth Power, Rotom forms have their appliance moves, Kingambit has Sucker Punch, etc.
Fixed scraped-tournament move typos: Protject→Protect, Sludge→Sludge Bomb, Huricane→Hurricane, Dark Pukse→Dark Pulse, Match Gotcha→Matcha Gotcha, sword dance→Swords Dance.

v1.2.10

Fixed Champions Pokemon loading with all-zero SPs — now pre-fills 32/32/2 offensive or defensive spreads based on base stats.

v1.2.9

Added Accelerock (was missing entirely) and gave it to all three Lycanroc forms.
Applied Pokemon Champions move changes: Growth is now Grass-type, Crabhammer 90→95 acc, Bone Rush 25→30 BP, First Impression 90→100, Spirit Shackle 80→90, Trop Kick 70→85, Apple Acid 80→90, Grav Apple 80→90, Infernal Parade 60→65.

Shadow Claw and Dragon Claw are now slicing moves (boosted by Sharpness).

v1.2.8

Added Basculegion-F and Gourgeist-Small/Large/Super.
Swapped Patrat out for Watchog in the Champions legal pool.
Removed bogus mega stubs (Raichu-Mega-X/Y, -Mega-Z entries, Magearna megas).

v1.2.7

Reg Ma usage data now derived entirely from the Pokemon Champions First Tour (532 teams).
Champions mode now shows move / item / ability usage percentages on cards and in the move explorer.
Mega forms in team pastes now correctly merge into the base species.

v1.2.6

Fixed Solar Beam and Solar Blade not having their base power halved in Rain, Sand, and Snow. Previously the calc could show ~2× the real damage against Drizzle/Sand Stream/Snow Warning users.

v1.2.5

Added a Reset button to the field bar that clears weather, terrain, screens, Tailwind, Trick Room, turn counter, and all +/- stat stage boosts on both teams in one click.

v1.2.4

Champions mode now shows real Reg Ma sample usage percentages for top Pokemon, computed as a 50/50 weighted average of Pikalytics Champions Preview and the Pokemon Champions First Tour (2026-04-09, ~1,021 entrants). Data covers the top ~16 meta Pokemon.
Pokemon Explorer in Champions mode now shows a usage % badge on each card and defaults to sorting by usage.

v1.2.3

Fixed conditional ability toggles (Zero to Hero, Guts, Multiscale, Proto/Quark, etc.) not persisting across page reloads — the state sanitizer was stripping abilityActive and the saved form data. Also restores a healing migration for Palafin stuck in Hero form.
Helping Hand move toggle now also persists across reloads (same root cause).

v1.2.2

Fixed Hard Stone not boosting Rock-type damage (was missing from the type-booster item list).
Fixed speed stage boosts (+/- buttons) not affecting the Speed Order panel.
Speed Order panel now applies weather-dependent speed abilities: Sand Rush, Swift Swim, Chlorophyll, Slush Rush, and Surge Surfer.

v1.2.1

Main damage table now shows KO chance under each damage % (OHKO / 2HKO / NHKO, with roll probabilities where applicable). Hidden for multi-hit moves.
Fixed Snow weather not applying the 1.5× Defense boost to Ice-type defenders (Gen 9 Snow mechanic).
