Basic animations:
Entrance: Summoned out of a Pokeball like the other Pokemon
Walk: A small set of water emerges from beneath Primarina, and she casually surfs the small wave
Dash: Similar to the walking animation, except this time, Primarina leans her body forward so that she can surf faster.
Jump: A wave of water appears beneath Primarina and surges upward, allowing Primarina to gain some elevation. If used in the air, this wave can push any nearby foe away similar to the normal water effect in Smash.
Double Jump: Primarina does an acrobatic flip in the air similar to that of a circus performer.
Tech: Primarina has a unique tech where if she techs, she will enter in a pose where she keeps her arms outstretched when she gets up.
Normal Attacks:
Jab 1: Sings a small tune, and the tune is represented with a single musical note that appears in front of Primarina and damages foes that are in range of it.
Jab 2: Similar to the first jab, except a second musical note appears after the first one.
Jab 3: Similar to the first two jabs, except a third musical note appears after the second one. When the three jobs are done together, the rhythm is similar to that of a "Do-Re-Mi."
Dash Attack: Primarina slides into the opponent with her arms outstretched.
Tilt Attacks:
Foward Tilt: Does a brief tail slap forward the front.
Up Tilt: Raises both of her arms upward as if she is trying to gain the attention of the crowd, dealing damage to anything above her.
Down Tilt: Shoots a small propulsion of water while crouching.
Aerials
Neutral Air: Performs an aerial cartwheel that damages anyone around Primarina.
Forward Air: Moves her tail forward while raising her hands in the air to look like a performer. A strong attack overall.
Back Air: Moves her tail backward while raising her hands in the air to like a performer. It is similar in strength to the forward air.
Up Air: Does a circular swimming-like motion. The attack hits twice: one from Primarina's body, the other from her tail. Her tail can even create a sweetspot that delivers strong damage and knockback, sending the opponent diagonally downward, if it makes precise contact.
Down Air: Moves her tail downward, creating a meteor spike if it hits the opponent underneath her at a sweetspot.
Throws
Grab: Shoots out a single bubble that can trap a single foe within it.
Pummel: Gently kisses the bubble that is trapping the opponent to deliver small amounts of damage. The attack can be delivered pretty fast, so its possibly to get a number of kisses for the duration of the grab.
Forward Throw: Slaps the opponent, breaking the bubble and dealing decent damage and knocking the opponent forward.
Back Throw: Moves the bubble trapping the foe behind her using her hands. Once the bubble has move behind Primarina, she sings a loud tune to pop it, dealing decent damage and knocking the foe away from her.
Up Throw: Sings a brief tune to raise the bubble trapping the opponent toward the air. Once it reaches a small distance into the air, Primarina sings a loud tune to pop the bubble, dealing decent damage and knocking the foe diagonally forward.
Down Throw: Slams her tail to the ground, breaking the bubble and delivering strong damage for a throw while throwing the opponent forward.
Smash Attacks
Forward Smash: Primarina releases a large powerful Bubble in front of herself that is bigger than the one used for her grab. The pop from the bubble delivers strong damage and knockback.
Up Smash: Primarina throws her arms in the air and creates a sphere of water above her. This sphere of water delivers strong damage to anyone caught within it, and the sphere of water transforms into a Rainbow Flourish when the attack ends. Visually, this attack strongly resembles Water Kirby's Rainbow Rain attack.
Down Smash: Primarina swims around in circles while crouching down. Those caught within the Down Smash will be trapped and end up receiving strong damage and knockback. Those that aren't caught within Primarina's attack will be pushed back thanks to the water that is being splashed from underneath the Pokemon.
Specials
Normal Special: Sparkling Aria
Primarina's signature attack. It's a chargeable attack where blue energy appears above Primarina as she starts to sing. Depending on how much you charge determines the strength of the attack. When you stop charging, the blue energy explodes thanks to a powerful song, creating a set of blue energy-like explosions all around Primarina. The strength of these explosions will depend on how long you charge the attack
Side Special: Disarming Voice
Primarina releases a song that is projected as a beam of ring-shaped hearts from her mouth. The longer you hold the B button for this attack, the longer the beam travels. Much like Thoron, it can damage multiple opponents when caught within the beam's range. You can even direct the beam upward or downward depending on where Primarina is standing.
Up Special: Aqua Jet
Primarina enshrouds herself in water and shoots herself forward at a fast rate just like a rocket. As she moves, she twirls within the the water. If she makes contact with a foe, the attack will deliver some strong damage and knockback. Visually, the attack looks similar to how it is used in the anime. Mechanically, the attack works similar to Corrin's Dragon Lunge. Much like Corrin and Rosalina's Up Specials, Aqua Jet travels in a small slant by default, but you can control how you want Primarina to fly in the air using the D-pad, even directing Primarina in a way that you can have her shoot herself vertically straight.
Down Special: Hyper Voice
A chargeable attack where Primarina puts both of her arms at her throat, doing some vocal practice to prepare to let a loud cry. How long you charge determines on how strong the attack will be. When she releases her cry, transparent circles come out of her mouth and push foes away much like what some water attacks do in Smash. Overall, this attack is very similar to Mario's F.L.U.D.D.
Final Smash: Oceanic Operetta
Primarina's Z-move. Primarina stands up and starts singing as water starts to rise and surrounding her. The water forms one giant bubble above her. She then moves the bubble around in a sort of “gentle push” like motion just like in the games. You can control where you want the bubble to move, but it will move slowly. She then sings one powerful tune, causing the bubble to fall, and once it reaches an opponent or the ground, it delivers huge damage and knockback to those it makes contact with. Water from the bubble then rains on Primarina as it bows just like in the games when it finishes its Z-Move.
Taunts
Up Taunt: Primarina stands up and extends her arms while singing a lovely tune outward similar to the games
Side Taunt: Primarina sings out a very small bubble that pops shortly afterward
Down Taunt: Primarina faces the camera and bows
Victory Animations
Animation 1: Primarina twirls around, then stands up and throws her arms in the air while singing a tune.
Animation 2: Primarina bows towards the left and right sides of her, and then she bows towards the camera.
Animation 3: Primarina gracefully jumps on several floating bubbles and then lands gracefully from the final bubble.
