Pit v Olimar guide, by Yin

Generally, Olimar is mostly going to be grounded, zoning you out with Fsmash and SideB, alongside punishing whiffs and such with grab
The main cases Olimar is gonna be out of the air is to gain extra distance on SideB, or a surprise nair.
You can sorta figure which one he's going to do depending on the next Pikmin in line, which you can see if you're attentive to the arrow pointing at the next Pikmin
For example, Olimar is rarely going to be using a purple pikmin Fsmash with the intention of spacing you out, and will generally be using it to SideB if your percent is too low for a kill.
Get yourself familiar with what each Pikmin does, and you'll be able to see what most are intended for.
If you don't wanna look it up yourself, just to list how each work
I'll go in the order of Pikmin plucks for this, so RBYWP
Red has the standard 8%, and has the strongest aerials out of all the Pikmin, alongside an immunity to fire
Pretty in Pink :sparkling_heart: | Yin ~ ☆ - Last Sunday at 1:00 AM
Blue has an extra 3 HP from the standard (11%), doesn't drown in water, and possesses the strongest throws of the Pikmin, having the most range of them, alongside having potential as a kill throw with Uthrow, although that thing can be very rage dependant(edited)
Yellow has the standard 8 HP, and possesses the most range and hitstun out of the Pikmin in terms of normals. Yellows shoot at a much higher arch in comparison when used for a SideB, which can be a bit easier to avoid, but also a lot harder to catch and avoid at times depending on the situation. This one is immune to electric attacks, meaning something like Electroshock actually won't break it.
Whites don't do as much in terms of attacks, and is a lot more easily killed than the other Pikmin (7 HP), but they make up for it, thanks to having a slightly longer grab than standards, alongside the strongest pummel in the game. However, where the fun starts comes in SideB, due to how fast and far this thing goes in comparison to other Pikmin, and how this racks up way more damage upon latching than all the other Pikmin
Purples are the heaviest among the Pikmin, and while short ranged all around in comparison to everything else, it's the only thing that deals knockback with SideB, is the most durable of Pikmin (13 HP), and has the strongest smash attacks. However, by being the heaviest, it's the easiest to hit on the way back, and slows down Olimar's recovery the most of the Pikmin
With that out of the way, now you can probably get a basic idea of which ones are going to be used for what in the neutral
However, there's one thing that can complicate the neutral from your side, and that's SideB.
Whenever a Pikmin is latched onto you, they also lag any hitbox you throw at you
this becomes very noticable with your multi-hits
So if you're gonna be killing the Pikmin off, don't use things like nair or fair
Generally, you kinda have to be patient for an opening
It's worth noting that all of Olimar's Pikmin have projectile properties, meaning they can't trade, can only win or lose.
Oh it's fine lol
but if you're already doing it, might as well
Alright, back on track
Since they can only win or lose, you don't have to worry too much about breaking through them with things like dash attck if they're getting really trigger happy with things like SideB'
You can also usually punish things like whiffed grabs, but it's still sorta weird at times
However, if you do force a shield, go nuts, as Olimar does not have great OoS options
Just be aware of which Pikmin he has next, as it limits what he can immediately do
Now that you can find room for openings, the minute you touch him, don't let him touch the ground again
Which is actually very easy, as Olimar is one of the worst characters at landing
Even if you can't carry for that long, just putting him away from the stage is fantastic, as he has a hard time regaining stage
If you put him offstage in that case, even better
As his recovery is fairly bad.
Mostly because while he can use a hitbox, it forces freefall afterward
So generally, he can't fend you off with a hitbox during his recovery, meaning you can freely swat him away till the fuel in UpB dies, as it doesn't come back till he returns to the stage
There's a very popular thing among Olimar mains as of late, which is avoiding ledge entirely, and floating just above you with a nair
This is really easily punishable if you see it coming, so take notes if you see an Olimar doing this
If he goes for ledge, he really only has one or two mixups from the ledge, and both are generally meh if you see through them
The first is ledgehop purple pikmin SideB
This one is okay since it forces shield, but you can usually catch him on the way down.
The second is another UpB, into that falling nair situation I explained earlier(edited)
Similar deal as last time
Other than those, all Olimar can do is the standard ledge options, which can be punished on reaction.
Generally, depending on percent, I mostly just reset the situation till I can convert a kill off of it, or put him in an even worse spot, like recovering again.
I think that's about all I wanna say about the MU
