Meowscarada is a humanoid feline Pokémon with light green fur covering most of its body — stopping just above its long, dark green legs — and a short, fluffy tail. The fur is especially longer around its ears, thighs, and arms, the latter resembling poofy sleeves. Its face has lazy pink eyes and a small pink nose, and is covered in a four-pointed mask-like shape, with a pattern of three green diamonds on it. Each of its hands has three fingers tipped with green claws, as well as a pink paw pad. On its neck is a pink collar resembling flower petals. This collar holds together its cape, which grows from the leaves it had around its neck as Floragato. The cape is lined with reflective fur, is black on the outside and green on the inside, and splits into two near the base, with both parts of the cape ending in fleur-de-lis shapes.
Meowscarada carries a four-petaled green flower, whose stem is hidden by the reflective fur on its cape, creating the illusion of floating. The flower can blossom into a round, pollen-filled flower bomb, with a two-tone green and black zigzag pattern on the outside, and six petals adorning the top. In a battle, Meowscarada uses skillful misdirection to stealthily plant these flower bombs onto various surfaces around its unaware foes before setting them off, catching their opponents off guard.
Meowscarada has a proud, showy personality; however, it is also sensitive and prone to jealousy. It can often be very attached to its Trainer, and it will become upset if its Trainer gives attention to other Pokémon.
Meowscarada is the only known Pokémon capable of learning the move Flower Trick.
Meowscarada appears to be based on a feline — possibly the Iberian lynx — and a magician, with its high Speed and Dark typing likely inspired by the sleight of hand needed to create a convincing act. Its category and signature move seem to be inspired by the magic trick of making flowers appear. It also seems to take inspiration from a masquerade ball or the holiday Mardi Gras, which often involves participants wearing masks. Mardi Gras and its decorative masks are especially popular in New Orleans, which was once under Spanish rule.
Meowscarada may be a combination of meow and mascarada (Spanish and Portuguese for masquerade).
Masquernya may be a combination of masquerade and ニャー nyā (onomatopoeia for meowing).
