Not sure who a Fighter would be given most of the characters function the same as regular Pokemon and have no real distinction other than speaking and maybe clothing if you're lucky, but there's not many standouts, so I'll exclude it for now.

Potential Stage Ideas:
Great Canyon
Sky Tower
Treasure Town
Temporal Tower
Glacier Palace
Tree of Life

Items:
Seeds: Appear using their overworld appearance from the PMD series. The Seed can be a wide variety of different Seeds, but it cannot be ascertained which is which until picked up.
Plain Seed: Does nothing, acts as a regular item you can toss. Will disappear after a while or if thrown a number of times.
Totter Seed: When picked up, stuns the fighter similar to Deku Nuts, leaving them open for attack.
Quick Seed: Gives a speed boost to the fighter who picked it up, consuming the item like a food item.
Hunger Seed: Upon consumption, will slow down the fighter's movement speed and decrease jump height. Moves will also move more sluggishly. This will wear off after a short while.
Sleep Seed: Acts as a throwable item. If it hits an opponent, will put them to sleep and cause the item to despawn. Sleep will last longer the more damage done to the opponent prior to being put to sleep.
Blast Seed: Acts like a Plain Seed in that it's a regular item you can throw, but when thrown, creates a massive explosion that deals heavy damage and knockback to whoever it hits. Is a rarer Seed thanks to its blistering power.
Reviver Seed: The rarest Seed. When consumed, it will automatically heal all damage done to the one who used it, resetting them back to 0%.

From Kirby's Dream Land 2 comes the embodiment of darkness....
(Boy who coulda guessed this was coming)

Overview:
Dark Matter slinks out of the shadows once again, this time to help Kirby out. He's attempted to cover Dreamland in darkness multiple times, but Kirby and his Animal Friends managed to save the day! Who knows why he's here to help Kirby out this time, but Kirby can never say no to a new friend! Regardless, Dark Matter Blade uses all of his shadowy repertoire to stop whoever's in his path, no matter who stands in his way. Using the power of the Rainbow Sword and his Dark Matter abilities, it sure doesn't look like anyone's going to stop him......

Moveset:
Unique Mechanics/References: Dark Matter can fly in the air. His blade has the sword clash effect, similar to Meta Knight and Sword. He'll change into Dark Matter True Form for certain aerial attacks.
Dark Beam: B (Dark Matter fires a brief shot of energy forward. These act as projectiles.)
Dark Charge: Hold+B (Begins charging Dark Barrage. A dark orb will appear above Dark Matter's sword as he does this.)
Dark Barrage: Release+Dark Charge (Releases, releasing a fast barrage of multiple Dark Beams.)
Energy Shot: Up+B (Generates a ball of energy above his sword, which then releases. The orb fly rapidly away, and will bounce upon hitting walls or floors. It and Energy Barrage give the Zap element.)
Energy Charge: Up+B+Hold (Charges up a stronger Energy Shot)
Energy Barrage: Release+Energy Charge (Releases Energy Charge, sending three of the orbs flying around. They act the same as Energy Shot, except there's more of them.)
Dark Spheres: Down+B (Summons four orange orbs from Dark Matter True Form, and surrounds itself with them. Any enemies who touch Dark Matter will instead be hit by the spheres instead of Dark Matter taking damage. It and Dark Sphere Home In give the Sizzle element.)
Dark Sphere Home In: Down+B during Dark Spheres (Sends the spheres flying directly in front of it, homing on the nearest enemy and damaging them. If no enemies are around, they just fly straight ahead.)
Dark Thrust: Side+B (Rams straight forward with sword pointed out. Has Cutter effect applied.)
Dark Thrust Charge: Side+B+Hold (Charges a stronger Dark Ram)
Dark Ram: Dark Thrust Charge+Release (Dashes straight forward, except with far futher distance and power.)
Dark Slash: Dash+B (Repeatedly slashes directly in front of itself, dealing damage to all it touches. Has a Cutter effect applied, allowing it to cut grass and vines.)
Dark Shot: Midair+B+Directional Input (Shoots a dark beam of energy forward, similar to Gooey's Mock Matter Laser. However, Dark Matter has the advantage of being able to send it in any direction. They all have different inputs but I'm lazy to list them out so they're merged together.)
