Five of each, huh?
Characters:
Captain Toad:
See this video I did a year ago prior to Ultimate's reveal. Swap the plant for a more traditional grab, the mudtroopers for some Boos and we done.
Note; his aerials can be performed by running into a weaker neutral B, lifting him off the platform and giving some air time.
Meowth: Specifically the Team Rocket Meowth. Meowth has a heap of weird gadgets and gizmos, not dissimilar to Bowser Jr. He has a move that throws James Bottle Caps to perform 'Pay Day'. Final Smash is a Mecha Meowth.
Impa: Uses a combination of light, shadow, water and fire magic, through a giant blade and a nagianta. Very quick and summons her other various incarnations for her Final Smash to help beat down the opponent.
Dixie Kong: Strong aerial game and has a walkable grab. She can summon a few of the animal buddies for some of her smash moves such as Enguarde(uses a sword...fish). Final Smash, she rocks out on her guitar riding on the back of Espresso...not Rambi though as he's saved for later...
Bandana Waddle Dee: Spear fighter(dur), charge the spear to ignite the tip and penetrate through walls with your long pokey stick. Has a chargable Megaton Punch that, similar to Joker, can absorb a ton of damage during charge before release. Final Smash: Possessed by Dark Matter and corrupted into Bandana Waddle Doo. Beam energy seismic tosses the opponent into the floor.
Five Assists:
King Boo: A huge intangible creature that floats through the stage and harasses you with paralysing licks.
Bubbles: Several pins are set up around the stage. Bubbles builds up speed by bouncing off of each. When she reaches max speed she can KO midweights at 85% damage.
Rambi: Here he is. Rambi does exactly what you think he'd do and charges around the stage with reckless abandon. A more powerful Gogoat.
Soren: Soren performs Rexclaibur, which targets an opponent encasing them in ice. When the ice shatters it turns into several whirlwinds. These whirlwinds behave similarly to the Hyrule Castle stage, blasting the poor schmuck in the middle skywards.
Gooey: Gooey can copy an opponents ability. Whilst he's out Gooey will grab an opponent with his tongue and copy that characters neutral B move until he disappears similarly to Kirby.
Five Pokeballs
Alakazam: Alakazam creates a temporary shift in the gravity with his strong telekinesis, causing all opponents to be forced to float in the air. Whilst they can still fight, they cannot hit solid ground. Beware using your Up + B specials!
Machamp: Machamp is the king of muscles. This Machamp charges at the opponent and unleashes a flurry of punches not dismiliar to DK's new Final Smash. KO's Midweight fighters at the low percentage of 30%.
Shiftry: Much like Soren, Shiftry plays with whirlwinds. The only difference is Shiftry launches multiple whirlwinds at once and doesn't target any opponent with this move.
Lopunny: Kicks skywards whoever comes near it as it bounces around the stage. Get hit too many times and expect a Chun Li style barrage!
Oranguru: Oranguru easily changes the tide...when summoned he summons TWO Pokeballs himself. It's a two for one Pokeball deal!
Five bosses:
Vaati: Vaati is a two stage boss. He starts in his small Toon Link-esque form, whipping up whirlwinds and trying to push opponents off the stage with his windboxes, however after taking enough damage he transforms into a giant eyeball monster. Every part of this form of Vaati bar the eye is immune to damage. His whirlwind attacks are now mixed up with lightning attacks and dark magic too.
King Bob-Omb: Particularly vulnerable to grabs, King Bob-Omb will try and throw you off the stage. He's immune to most attacks bar grabs, grapples, throws and special throws such as Incineroar's side B or Yoshi's egg lay. Upon taking enough damage he'll ignite and then the boss battle is a race against time!
Medusa: This particular boss starts off at Palutena's size but grows to an enormous size during phase 2. Beware her petrification which will freeze you in place and leave you EXTREMELY vulnerable to Medusa's follow up assault.
Andross: A shooter style boss, Andross appears at one end of the stage as you try and 'fly' around the various projectiles he shoots at you, similar to the credits game in Ultimate.
Master and Crazy Hand: Standard stuff. Gotta have the hands. Let's have them both at once again...*shudders*
Five stages:
Glitz Pit: Paper Mario gets a second stage, complete with a cheering audience of paper wrestling fans. Watch out for Rawk Hawk as he dives off the stage to try and get involved with YOUR personal brawl. You may even see some famous Paper Mario partners in the audience! (Hazards can be turned off)
Wingo's Watch Tower: A huge castle that occasionally gets assaulted by a big angry avian sorceror shooting down lightning bolts, windboxes and...giant turnips? The turnips can be used as items to throw at the opponent. KO'ing Wingo will net you an additional KO, similar to an assist kill. (Hazards can be turned off)
Kakariko Village: A (mostly) peaceful Sheikah village. Purah yells words of encouragement to you from the background and at night fireflies light up the skies. Watch out for villainous Yiga harassing the peaceful sheikah. KO them and be rewarded with a visit from the Great Fairy Cotera who watches over the village...and will drop fairy bottles from the sky. (Hazards can be turned off)
[NAME REDACTED]: ARMS gets it's first stage(perhaps unfairly before it's first character). Welcome to Dr. Coyle's lab. The glass capsules are breakable, and the conveyor belts could trip you up...you may see a few of the famous ARMS fighters in the background cheering you on. Guess they're glad to not be the ones having to fight this time! (Hazards can be turned off)
Busted Bayou: Come to this gorgeous part of Donkey Kong Island where characters are reduced to silhouette form. It may take a little getting used to, but this stage flattens the characters to a shadow puppet form with some highlight colours for their character. Outside the art gimmick, the stage is pretty standard; mostly flat with a few platforms to play on and no hazards.
Okay, I could go into tracks but I think I've given people enough to read.
