Alright, my husband works at nintendo and I’m kinda mad at them for firing him, so I’m gonna leak everything he told me
>Porky Minch from the Mother/Earthbound series joins the battle as a powerful and somewhat large fighter that is easy to read, almost like a boss fight. He uses his design from Mother 2/Earthbound in the spider mech, the same one used in Earthbound's semi final boss, but he does have a skin that makes his skin colors and face match Mother 3, as well as have a pig mask symbol(a pig nose) on his mech. His attacks include long jabs with his spider like legs, he can release gas that stuns the foe,tear into other fighters with a sharp jab of his leg, and use his legs to boost himself high up into the air. What I mean by him being telegraphed like a boss is that, for example, his Neutral Special, Gas Cloud, has his robot charge up energy, showing his mouth open like he's sucking up energy, and then after about 2-3 seconds of charging, he releases. You can not only easily outrun this in the time he charges, but if you attack his glass shell during this, it cancels the attack and deals extra damage. Or, his Up Special, spider bounce, has him crouch the machine down, then boost up, but if you hit well he is crouching, it sends him downward. He is fairly frail to compensate for the power of his attacks. He can be ko'd by pretty much any smash attack at 60% or higher.
>Golisopod from Pokemon is a new character. Yes, of all the new Pokemon, it seems Sakurai added Golisopod. This Water and Bug type is somewhat sluggish but is primarily based around quick attacks and getting away. For example, it’s dash attack is a quick swipe, but at any point in the animation you can press a again to dash back about 2/3rds the length of one battlefield platform. It’s Neutral Special is literally based around this, being U-Turn. Golisopod glows green and dashes forward, but if the attack connects, Golisopod goes backward. It’s rather bulky, and decently strong, especially since its Side Special, Razor Shell, can temporarily lower a foes defenses. If it weren’t for its sluggishness, it might be a pretty good character, as it has some great strengths such as easily being able to escape from a foe, and having a decent amount of long ranged moves like Water Pulse as a forward smash and Sludge Wave as a down air, making spacing not be a problem. Arguably it’s most unique feature is First Impression. The first 3 attacks they use do twice as much damage and if hit on the sweet spot, can spike. It is because of this that I have seen some players back at the treehouse sometimes SD in order to get some strong attacks in.
>Susie from Kirby is added as Sakurai has heard about the complaints that only Kirby content from his games is in, so he added her as she is from Planet Robobot, the newest Kirby game at the time Ultimate started development, it wasn’t even quite out yet, actually. She is a tech based character, with attacks like a tazer that does damage and stuns foes for about as long as Zero Suit Samus’s Neutral Special as her Side Special, or a multi-hitting drill attack has her back air. She is a fairly speedy character, but also somewhat frail. She uses attacks from the Robobot itself in her moveset, explained in smash that she somehow installed it’s attacks onto herself as her outfit is rather technological. This includes a chainsaw as her Forward Smash, a long burst of fire as her Up Smash that can even set foes on fire, dealing gradual damage for a few seconds,unleashing a loud sound wave for her Down Smash, growing wheels for her Dash Attack, dashing forward and growing jetwings for the animation of her forward air, a strong and lengthy electrical jab as her Neutral Special, a turbo charged spinning Parasol as her Up Special, and even dropping a contact based bomb as her Down Air.
>Banjo and Kazooie are one of two (non echo) third party fighters added to this game. They’re a lot like Duck Hunt in that they can have 2 sources of attacks at once, like their Down Smash, Breegul Bash, which not only damages from the shock wave it causes, but also Kazooie herself. They have 3 jumps, two from Banjo and one from Kazooie, and of course can then recover with Beak Bomb. Their Neutral Special involves shooting eggs from Kazooie, which can be charged. Simply pressing the button or pressing for less than about a second or 2 shoots a regular, blue egg. Holding from then on up to about 3 seconds shoots a spotted, fiery red egg. Charging past that will instantly shoot, regardless of whether you release the button or not, a green, lined Grenade Egg that creates a small explosion, stunning the target. One of their more interesting attacks is their Side Special, Wonder Wing, which lasts for about 2 seconds(or less, ends if you let go) where they cannot be harmed and hurt enemies. However, to compensate for how useful this move is, they have an un-cancelable opening up animation where they slowly open up, stand up with their arms out, stretch them a bit and close, which takes about 2 seconds. This animation does end if they are attacked but that’s obviously not ideal. One detail I imagine was hard to implement is that when dashing Banjo rides on Kazooie, often known as the Talon Trot. People will likely be happy to hear there are zero nuts and bolts references within their moveset.
>The final (unique) newcomer, Phoenix Wright from Ace Attorney. His moveset is mainly about exposing weak spots and finding good opportunities to strike. His Neutral Special, Objection, has him point his finger and say the iconic phrase, along with the text bubble showing up as he stuns any foe touched by his finger. His Down Special, Examine, has him guide a small square to a spot on the screen and examine it. If it’s a fighter, it will either do nothing, or within a small hitbox on every fighter, designed to be near the middle of their model, it will make them have a thick red outline, and when attacked, they will take double the damage and knockback they would normally for just one attack. One of the coolest aspects of his moveset is how he references various objects and items throughout the series, such as dropping the Sacred Urn for his Dash Attack, whacking foes with the Thinker for his Up Smash, or even stabbing with the Samurai Spear as his Forward Aerial. For being a Lawyer however, some of his moves are a bit wacky, such as his Up Special involving him bouncing off a desk that appears midair, or his Side Special throwing evidence whether it be papers, a banana, or a cup of coffee. His skins are actually pretty inspired, being based off other Ace Attorney characters, mainly(but not exclusively) other lawyers, like a red and white coat for Apollo, a scarlet coat for Edgeworth, but also things like a green coat for Gumshoe and a purple coat for Maya.
