What it does
Huge Power doubles the holder's Attack stat. The calculation runs as though the holder has twice its listed Attack, then applies nature and EV bonuses on top of that doubled base. A 50 Attack Pokémon with Huge Power effectively operates at a 100 Attack base before EVs — and Azumarill at 50 base Attack becomes equivalent to roughly 135 after the doubling, eclipsing most dedicated physical attackers.
Diggersby sits at 56 base Attack and reaches the equivalent of about 146. Both of them look like they shouldn't hit hard. They do.
Huge Power multiplies the stat value, not the damage output directly — items and type bonuses stack on top normally.
Who runs it
Azumarill (96%) is the most recognisable Huge Power user in Champions. Water/Fairy typing gives it blanket coverage in both directions — Fairy blocks Dragon-type threats, Water hits broadly, and the doubled Attack turns Play Rough and Waterfall into genuinely threatening moves on a Pokémon that also has 100 HP to work with. Aqua Jet is the closer: priority Water move off an effectively massive Attack stat, excellent at picking off weakened targets.
Diggersby (99%) hits even higher usage rates. Normal/Ground gives it Earthquake and Quick Attack, and the 56 base Attack becomes brutally high once Huge Power enters the equation. It can run a Belly Drum set — losing half its HP to max out Attack — and between the drum and Huge Power the total multiplier approaches ×8, which ends games.
How to use it
The core discipline is knowing your damage benchmarks. Opponents consistently underestimate how much Azumarill hits for; use that. Before clicking an attack, check whether the target survives — if it does, think about whether you want to commit or pivot.
Choice Band pushes damage output to absurd levels but locks you into one move. Assault Vest patches up Special Defense so Azumarill can absorb hits from both sides — tougher to wear down, tougher to ignore.
With Belly Drum: you need a safe setup turn, then Aqua Jet to clean up. Without that setup turn, Belly Drum loses you half your HP for nothing. Get the entry right.
Tips & strategy
Neither Azumarill nor Diggersby is fast. Priority moves — Aqua Jet, Quick Attack — are how they deal with faster threats. If you're running a Huge Power set without priority coverage, you need speed control or a weakened opposing field.
Will-O-Wisp halves Attack after burning. Combined with Huge Power, the net effect cancels out — the holder ends up at roughly normal Attack levels. Switching out is the only clean answer; keep that in mind when Ghosted- or fire-type support is on the opposing side.
Pure Power is mechanically identical — same doubling, just a different ability slot name on different Pokémon.
