Ice hits for ×2.56 — Hydrapple's Grass/Dragon typing is double-weak, so those attackers outperform their score gap.
Watch its Grass/Dragon/Rock moves — counters like Kyurem (White) and Eternatus take super-effective damage from them.
Snow weather boosts Ice moves ×1.2 — the best time to battle Hydrapple.

Rankings are estimated cycle DPS (attack stat × move damage ÷ cycle time, with STAB and type effectiveness). Not a full battle simulation.
