animal from squeak squad

or drill

Martian Madness drop - Robobot Mech Mount

From Kirby's Planet Robobot

Edit: I should have posted this in ideas but I'm too lazy to move it.

Corrupt (from Eaters of Souls and other applicable Corruption enemies)

LMB to fire Vile Spit
Passive: Immune to Darkness and Weakness

Crimson counterpart functionally identical, the projectiles are just blood-themed instead

If an upgrade system for abilities like Forgotten World's is on the table, consider having the upgraded versions of these inflict their associated debuffs (Weakness / Ichor) or gain an additional attack (Cursed Flames / Golden Shower projectile)

(This is a long list, sorry if it's too big.)

Fighter (melee)

Hammer (melee)

Archer (ranged, since it's a bow as well, can be boosted w/ Archery potions)

Ranger (ranged, gun)

Bomb ("ranged", and maybe Dynamite for an upgraded version)

ESP (magic)

Missile (honestly idk)

Wheel (melee, probably)

Spark/Plasma (magic)

Water (magic)

Cutter (ranged/melee)

Sleep (it'd be funny to add something useless, though you can try using the version from Kirby Battle Royale as well)

Cook (maybe melee, can be used as support)

Yo-Yo (melee, can be buffed with yoyo buffs)

Doctor (probably neutral, Doctor can count for melee, ranged, and magic)

Bubble (magic)

Mirror (magic)

Jet (probably neutral? or whatever you'd give Missile)

UFO (magic or ranged, can prob be inhaled from Martian Madness

Animal (melee, increase mining speed)

Artist (summoner finally, can make art allies)

Circus (summoner?)

Bell (dunno, maybe summoner)

Whip (summoner, gets buffed by whip buffs)

Again, apologies for the big list, it's just ideas I have for at least copy abilities from official Kirby games. And plus, some copy abilities might be better off as something else that doesn't take up your ability slot. Like Jet/Wheel being mounts or whatever.

get a placeable ability of bosses when defeated

Super abiltys like:
Ultra sword
Flare Beam
Grand Hammer
Snow Bowl
Monster Flame

I know someone else mentioned the martian invasion for robobot armor, but what about the search drone that starts the event when it scans you. What if when you inhale it, you just straight up get the UFO ability?

Also, maybe find a way to work in the Master ability from Amazing Mirror. You could make it a post plantera/golem thing

Spider, since no-one remembers it and it could be funny. Making 'lil trampolines and shooting sticky-slowing webs.

Wind ability which can be get from winged entities

C O M B I N I N
G COPY ABILITIES

a few terraria specific abilites, could be a fun addon

What if from the blood moon minibosses you could get some kind of blood surfing Ability that you can temporarily fly with and damaging blood rains down from under where you're surfing? Might be a bit morbid for kirby but it's terraria so yeah.
