Azumarill

A river rabbit with a body as round as a float and ears turned into antennae. The Pokédex entries focus on its hearing before anything else: those long ears act as sensors and detect the movement of living things on the riverbed, with the water in between. The oval pattern on its belly isn’t just decoration — it helps camouflage it while swimming.

It spends almost all its time in the water, and on clear days it comes out to float on the surface and sunbathe. The behaviour mentioned most often is that of a caretaker: it makes air bubbles, uses them to cover Azurill when they play in the river, and also to keep any Pokémon that is about to drown breathing. The official category, Aqua Rabbit Pokémon, doesn’t quite cover all that.

It is 80 centimetres tall and weighs 28.5 kilograms, an unusual density for its size: it is short, solid and full of water. It completes a three-stage line that starts with the baby Azurill and passes through Marill, and it is the only one of the three to lose the ball-with-tail look.

The stat spread is deceptive. 50 Attack is the sort of figure you’d expect from a harmless Pokémon, and that’s the whole point: Huge Power doubles its Attack, so that 50 behaves like a base 100, with the advantage that items and stat-stage boosts are applied after the multiplication. Around that, it has 100 HP and 80 in each defensive stat, enough to take neutral hits, and a Speed of 50 that condemns it to move second against almost everything.

Water and Fairy split the work nicely. The immunity to Dragon comes for free, the resistances to Fire, Water, Ice, Bug, Dark and Fighting stack up, and it only leaves three openings: Electric, Grass and Poison. Thick Fat halves damage from Fire and Ice; Sap Sipper, its hidden ability, simply removes its Grass weakness and even raises its Attack when opponents try to exploit it. Three abilities, three different plans.

It has no shortage of moves: Play Rough at level 25 and Aqua Tail at 21 give it both physical STAB moves at 90 power each, Superpower arrives at 50 for anything that resists Fairy, and Ice Punch is taught by TM. The special side is the one to leave alone. Hydro Pump comes in at level 40 with 110 power, but it runs off a Special Attack of 60 with no ability to back it up: in practice, it hits less hard than almost any of its physical attacks.

What holds it back is its pace. Without anything to fix that 50 Speed, every exchange starts with it taking a hit, and against an Amoonguss or a Ferrothorn — both of which resist its two types — it has no way to force them out.

It belongs to the Water 1 and Fairy Egg Groups, a combination that lets it breed with both riverside wildlife and a good chunk of the Fairy-type catalogue. The gender ratio is the standard 50 and 50, so the female isn’t the usual bottleneck found in other evolutionary lines.

Ten incubation cycles are about 2805 steps, putting it among the shorter stretches in the Pokédex. It’s worth knowing that Scarlet and Violet assign it no Egg Moves: everything it learns comes from levelling up or TMs, and the list is long, with Misty Explosion, Misty Terrain and Liquidation among the useful options.

The evolution has no trick to it: Marill reaches level 18 and that’s it. The previous step does, because Azurill only becomes Marill when it levels up with friendship at 160 or higher, and like all babies, it has to be hatched from an Egg by breeding the adults. Its base friendship, 70, leaves quite a bit of ground to cover.

In the wild, it appears along the water’s edge, and its catch rate of 75 puts it in the middle ground: considerably more forgiving than the starters’ 45, but nowhere near the 255 of a first-route Pokémon. It grows at a fast rate and gives 3 HP effort points when defeated.
