It evolves from Milcery while holding a Sweet when its Trainer spins and strikes a pose. The form it takes upon evolving depends on the time of day, the length of the spin, and whether the Trainer was spinning clockwise or counterclockwise. Its appearance is further determined by the type of Sweet that is held.
Milcery evolves into:
Vanilla Cream Alcremie after spinning clockwise for less than 5 seconds during the day.
Ruby Cream Alcremie after spinning counterclockwise for less than 5 seconds during the day.
Matcha Cream Alcremie after spinning clockwise for less than 5 seconds at night.
Mint Cream Alcremie after spinning counterclockwise for more than 5 seconds at night.

Salted Cream Alcremie after spinning counterclockwise for less than 5 seconds at night.

Caramel Swirl Alcremie after spinning clockwise for more than 5 seconds during the day.
Rainbow Swirl Alcremie after spinning counterclockwise for more than 10 seconds during the evening (between 7 and 7:59 PM in real-time in SwSh).
Alcremie has a Gigantamax form which is the same regardless of Alcremie's form.
Alcremie is a vaguely anthropomorphic Pokémon with a body made of whipped cream. Its head resembles several clumps of whipped cream styled like hair, with a large crowning blob flanked by two loop-like "bangs." Each of these bangs is topped with the Sweet Alcremie was given to hold as a Milcery when evolving. Alcremie's lower body is similarly composed of two dollops of whipped cream resembling a robe or a dress. It has two stout arms with three fingers each extending between the dollops of its body.
Alcremie's flavor and color are wildly variable and dependent on the time of day, direction, and duration for which it was swirled while it was a Milcery. An Alcremie's flavor affects the color of its body, which can be any of several pastel shades. Its eye color matches the color of its sweet. There are nine known flavors of Alcremie.
When a Trainer gains Alcremie's trust, Alcremie will treat them to Berries with cream. The content of Alcremie's cream can become richer and sweeter, the happier it feels. Due to the cream it makes being very delicious, many pastry chefs seek to have Alcremie as a partner. If attacked, it will throw a sweet-scented cream to distract or blind the opponent in order to escape. The cream's effect is powerful enough to make an opponent soothed and lose the will to battle if eaten.
In its Gigantamax form, Alcremie's body resembles a towering, five-tiered cake. The apical tier of the cake resembles Alcremie's regular body, though it's wearing a bow and its whipped-cream "hair" is styled into a flamboyant swoop. Each layer of the cake features a variety of sweets that can be used to evolve Milcery. The bottom tier of its body is frosted yellow and adorned with an alternating row of star sweets and dotted frosting. The second tier is frosted pink and features a magenta bow topped with a clover sweet. The third tier is frosted blue and encircled with a row of flower sweets featuring a berry sweet arch. The fourth tier is frosted pink and encircled with love sweets and three red clouds, with the central sweet being larger than the rest. Lumps of whipped cream surround Gigantamax Alcremie's body between each of its tiers. Gigantamax Aclcremie's cream is said to be endlessly pouring.
When the cream gets hit by a strong impact, the cream hardens depending on the blow. This allows Gigantamax Alcremie to be resistant to most physical attacks. Moreover, the decorations on Alcremie's body are as hard as diamonds. When attacking, Gigantamax Alcremie unleashes missiles made of cream, each one filled with 100,000 kilocalories. Anyone who gets hit by one of these cream missiles will be filled with energy and euphoria, but will become extremely confused and dizzy at the same time.
Alcremie has the most different recognized forms of all Pokémon, with 64. This consists of nine named forms, each with seven variants corresponding to the type of Sweet, plus a Gigantamax form.
Despite having the most different recognized forms, Alcremie only has nine Pokédex entries (one for each named form), making it the Pokémon with the second-most Pokédex entries for a single Pokémon as of Generation IX.
Prior to the release of Pokémon HOME, Alcremie was tied with Minior as being under the most Pokédexcolor groupings, with a total of six. The distinction is now held by Vivillon, with nine Pokédex color groupings.
Alcremie appears to be based on whipped cream, or eton mess, a British dessert made of fruit, meringue, and whipped cream. Its Gigantamax form may be based on a wedding cake.
Alcremie may be a combination of alchemy and cream, crème, or creamy.
Mawhip may be a combination of 魔法 mahō (magic) and ホイップ whip (whipped cream).
