There was an old topic about items speculation and discussion, but this one excludes entirely Assist Trophies and Pokeballs/Masterballs, so we can increase the focus on different items.
Put down bellow items you think would be nice to see in SSF2.

Besides the absent Cucco, there are a few I could think off:
A simple Checkpoint, it could be from the Sonic Series;
A Random Item Capsule, a collection of capsules from the Sonic Series;
The Coconut Shooter, from the Donkey Kong Series;
The Tracing Bomb, a bomb that appears on Super Bomberman 5, for SNES, from the Bomberman Series;
The Sentry Gun, a gun from the Worms Series;
Bub, the main protagonist from the Bubble Bobble Series, a character working as an item would be something really unique for SSF2.
And of course, I would like to see some of the items that appear on the other Smash games as well: The Fake Smash Ball, a POW Block, a Bullet Bill and the Banana Peel.

With how we have a Screw Attack item that makes your character "equip" it instead of simply holding it on their hand, I can imagine a "Franklin Badge" could be added in aswell

I think the Staff and Rage Gun from Ultimate could be good items. A new item should be the Stopwatch from Castlevania (when picked up, it freezes opponents for 3 seconds).

That would be a good item indeed, I never played Castlevania, but it sounds cool and unique.

The Evoker from Persona 3, it will boost your stats and give each character a Persona.
Oh and there's an animation of each character shooting themselves in the head.

Bring back Boost Pads and BAN Hammer.

Maybe an item that teleports you somewhere?

One I'd love and would be quite easy to implement:
Coconut Gun
Basically reusing the same code of the Ray Gun, replacing the sprite for a Coconut Gun sprite, as well as the ammo. Also lowering the ammo from 12ish to 6 or 8, and have the Coconuts hit harder.
Since every character is programmed to function with the Ray Gun, this wouldn't need as much work into it

This one is already in the first picture of the topic , I'm personally against replacing and removing stuff

The Coconut gun wouldn't be replacing/removing anything. It'd be another separate item that just reuses some of Ray Gun's code.

That kinda works like the Timer (not exactly the same way, though) or more closely to the paralyzing effect from Silver.

Honestly?
If more anime franchises that weren't playable were allowed
I think the Stone Mask from Jojo's Bizarre Adventure would have worked wonders, maybe have it as an item that gives you the Vampire status from Special Smash, and lets you heal from every attack you land on someone

Hey, it's only anime characters that aren't allowed. We can still get items and stuff. Remember, Paine?
