The irony here is that I know a Pikachu main who posts in this thread who has essentially stated this before.
Sooooooooooooooooooooooooooooo
Whoops.
Maybe you should ask "former" Pikachu players about these things
But this was pre-patch and they may actually have faith in Pikachu's merits again; Sheik isn't strictly better in 95% of game play anymore (and Meta Knight moving down a peg doesn't overtly ensure he's vastly better in nearly every threatening ability while sharing similarities).
I wasn't planning to make a Pikachu post, but since I've been "summoned," might as well.
Pikachu's niche in the game was great edgeguarding (ability to go deep with multiple aerials due to recovery distance/quick recovery) combined with long-range, spacing-disruptive shenanigans in Quick Attack, an amazing disadvantaged state (multiple aerials to escape, Thunder, recovery, QA to land, short frame/b-air). Sheik had better edgeguarding, a better long-range game (lol Needles), and a better disadvantaged state. Truthfully there was no reason to play Pikachu while Sheik existed. He didn't do, well, *anything* that she couldn't do better.
Most characters were overshadowed by prepatch Sheik, of course, but the attribute comparisons were never quite as direct as with Pikachu.
After the patch it's a little different. Pikachu's hard read tools are now better than Sheik's since her grab reward's been toned down (before Sheik "hard-reading" you just consisted of her predicting that you would be shielding and grabbing you, lol, which was so ridiculously safe), so you can feasibly use Pikachu instead if you are skilled at making reads. Sheik is still obviously the better character, though.
People misunderstand Pikachu frequently. If you take a look at some of the weaknesses Pika has been stated to have just in this topic alone in the last 2 or 3 pages, you'll find:
- low range
- weakness to swords
- low weight/survivability
- lack of kill confirms
- lack of mid and high % combos
- low damage output on single attacks
- predictable/avoidable edgeguarding
and then some that people missed:
- mediocre shield pressure and grab range
- above-average landing lag (though mitigated by use of generous autocancels)
- lack of a killing aerial
- some average/mediocre mobility parameters, like air speed, initial dash->shield, foxtrot
To me these weaknesses when combined outline/form the trappings of a bottom 10 character.
"But Solid! Pikachu can't possibly be bottom 10!"
He isn't, but with the way people (with the intention of fighting back against perceived Pikachu overhype) talk about him, especially in this thread, he sure seems bottom 10. But people seem hesitant to follow through to the logical conclusion of their observations. Posts about Pikachu will frequently top off a list of his weaknesses with "But he's still a solid high tier." What makes him high tier? That part always just goes unsupported.
If I were to make a case for it I'd probably mention his disadvantage, f4 jumpsquat combined with quick startup on aerials and tilts, and good walk/crawl/run which allows him to mix up other characters.
Some of those weaknesses are definitely exaggerated, too. For instance, I don't think that Pikachu has much of a problem with swords/disjoints because there are two sides to every coin. It's too shallow to say that "sword vs. low range, sword must win." This is the same line of thinking that causes people to underrate Mario. Once Pikachu is "in," he's very hard to get out again. With the best roll/spotdodge data in the game, he also gets in very easily. roll in -> up-tilt is an actual thing that works, for instance. pivot up-airs are also great against swordsmen in the same vein. Also, most swordsmen like trapping their opponents in advantage, but Pika escapes/ignores a lot of traps by resetting to the ledge with QA.
His swordsmen MUs are not too bad. Marth and Lucina were never really problems for him, and neither was Roy. Corrin's manageable, and even Cloud is fine (Pikachu probably loses, but it's not a roflstomp). Ike's the hardest of the swordsmen for Pika, but it has nothing to do with the sword and everything to do with Ike's shield game being very potent. Pikachu loses to grabs, jabs, and shields in this MU, not to Ike's massive disjoint (I mean, of course, disjoint is always better than no disjoint, that's just trivially true, but it doesn't affect the MU nearly as much as other factors).
If I had to prioritize his weakneses, it'd go something like:
#1 Pikachu
does have a problem killing, with no killing aerial or real confirm (d-tilt -> n-air? lol)
#2 shields work pretty well against him, as his shield pressure tools aren't amazing (watch ZeRo shield a lot against ESAM, for instance, almost as much as he shields against Nairo's ZSS, which is a tether grab character).
#3 Pika's neutral isn't that great. He doesn't have a safe poke, and tjolt is almost entirely useless nowadays since everyone powershields and then just does whatever (though you can use it to cover your approach in certain situations/MUs); it's too slow to actually do anything consistently. His grab range is kind of mediocre too.
Quick Attack is not a good answer to Pika's problems in neutral, despite how many people seem to get hit by/fall for it. It starts moving on f15, and the hitbox doesn't appear until f18, so it's definitely way more than reactable. People trying to predictively shield it probably have the wrong approach in mind. Your best option against QA is to take advantage of Pika's extended hurtboxes and throw out a devastating attack like a Rosa up-smash or Ganon n-air or something.
Sure, sometimes, Pika will react to your hitbox while moving and choose a safe location to retreat to with the second part of QA, or he'll move in a way that goes through you and then punish you. But the risk:reward here is always in your favor, because if you do manage to hit him (which will happen about a fourth to a third of the time), he just dies, and he's a character that has trouble sealing the stock himself, so reclaiming leads is difficult for him.
In 1.1.5 i think pikachu now outclasses sheik. sheik has superior frame data on her aerials, but now she's only 2 points heavier than pikachu, who actually has a kill confirm that's guaranteed unlike sheik.
This confirm doesn't work as a confirm.
Yes, you can just barely react and catch DI but you can only be ready to read
two directions at a time--either forward and no DI, or behind and no DI. It's more of a 50:50 than a kill confirm, and even that's assuming that your reaction time is just amazing; it's 1/3 if it's not. And even if it were guaranteed, it isn't overwhelmingly powerful especially from centerstage, so it's not nearly as good as some of the other kill confirms in the game.
I would be very happy to be proven wrong about this confirm, but as far as I can tell, there's no evidence to suggest that you can get it consistently, although I appreciate the effort that Pikachu mains are putting into the character.
