I'm bored so I'm going to give a brief overview of the characters I play and their MUs competitively.
Solid high tier but gets overshadowed a lot by better, easier characters. He has THE best neutral in the game and good combo trees but a pretty average recovery and disadvantage state, light weight and bad kill power. He can be good against characters who give a lot of the cast trouble like the rats and other vortexers, fighting game characters and a few top/high tiers like Peach and Pokemon trainer. This is due to amazing projectile zoning and f4 Nair and Dair covering him well vs characters without disjoints. However he has a bad disadvantage state vs characters with big disjoints due to all his projectiles losing to hitboxes, small hitboxes on his attacks and average mobility with no escape burst options. Curiously he does pretty well vs reflectors since most of his projectiles have little cooldown and he can sheild if they get reflected or angle them so they don't return to him. YL's worst MUs end up being swordies like Aegis, Hero due to bounce and accelerate, Cloud etc as well as some characters who just outclass him like Wolf and Joker.
another solid high tier. Byleth has great kill power off a strong advantage state with big hitboxes but a mediocre neutral due to slow attacks. She usually wins MUs by having higher reward for landing reads than the opponent. She struggles the most vs vortexers who can slip past her midrange zoning and stay on top of her like the rats and Inkling.
Although he's bottom tier he's still a very threatening character due to high damage and kill power on hit. Proof that Ultimate has no truely bad characters, just characters who are worse than others. With that said he does have to outplay pretty much everyone to win. If his recovery wasn't complete trash he'd be able to hang with other heavyweights like Incineroar but he gets gimped so easily. His worse MUs are probably characters like Minmin who can keep him away safely.
Always an underrated character, upper mid tier. KRool is the second best super heavy after Bowser imo. He is extremely heavy and has a lot of clutch factor moves to steal games. Unfortunately he suffers from having the second biggest hurtbox in the game and relatively small hitboxes. IMO he actually beats several lower ranked characters but gets outclassed by top tiers who don't have these huge weaknesses. His worst MUs tend to be weird CP characters who have specific tools that destroy him: Belmont keeps him in disadvantage forever and Villager steals his crown with pocket, zones him with sling shot F/Bairs and destroys his recovery with bowling ball Fsmash. ROB is really bad too.
To be continued...
I’m also quite bored, so I might as well do my opinions on the MU’s as Hero.
Vs.
: Quite an odd MU. While it is quite clear that Hero should win on paper, Hero can have some struggle with Young Link. The main objective for Young Link is to smother Hero at mid range projectiles and box him most of the match in order to prevent Hero from buffing. Hero on the other hand is mainly trying to fish for bounce and approach/bait aerials, spacing with forward air and getting early edge guards with acceleratle. The main issue is fire arrow. It can reliable force Hero out of menu, and it is possible to get bounce in menu, but fire arrows interrupt you before you can identify bounce is there. This leads to Hero needing to win neutral at least once or twice to get his buffs, but as you said, Yink has the best neutral in the game so it can be a tall order for Hero if he doesn’t wanna eat all his mana. Not to mention that when Hero does get a chance to obtain buffs, he has a tough choice. Obtain buffs, or edge guard? Hero is excellent at edgeguarding Yink, with giant disjoints beating up B like fair, bair, dair, and zap spells. He also could do ledgedrop kaswoosh at like 50% and kill Yink. Yet that’s also risky. If the Yink mixes his recovery, Hero gets a net MP loss due to needing to recover and also dealing with ledge traps. But when hero gets going,
he gets going. Hero can reliably camp him when he has the lead with excellent projectiles and menu spells, Yinks approaches are very predictable in general and Hero has one of the best anti-approaching tools in the game (Frizzle, zap, zapple, forward tilt, jab, retreating bair and fair). He is also quite capable of making a comeback. Due to Yinks struggle with killing, and Heros ridiculous kill power, Yink will often get Hero to the late 150%’s to 170%’s, forcing them kill with weak nairs and forward throws. Hero can start killing Yink as low as... 30%? If Hero can get both damage buffs he can easily condition shield. Forcing a Young Link to leave shield is extremely powerful, and it leads to Hero being able to just spam fair and bair since they
will kill at 50%. That’s not even mentioning the million other kill options Hero will have against Young link, (decently easy edgeguards. Kazan reads, snooze, half of menu in general).
There’s not even a point going over acceleratle. With it active he is the best character in the game...
Vs.
: This one is quite easy to explain in one sentence. “Onstage good, offstage bad.” Hero has a decent neutral against Byleth, surprisingly. While he has much less Sword reach than Byleth, zapple and projectiles easily beat areadbhar moves. Hero still does have the range to space out Up B as well. Hero also has decent speed, so he can run into Byleth and shield to mess with his spacing, forcing Byleth into an unfavorable scrapping situation. Not even nair can save Byleth, as it is punishable by woosh, (Nair is -10, woosh is frame 7) Once Hero is offstage Byleth can easily edge guard kaswoosh, though not zoom. Hero on the other hand struggles with traditional edge guarding. Instead, he can ledgedrop kaswoosh and confirm into a Bair for an easy kill. However Byleth can wait offstage and reel in once kaswoosh finishes. Hero can instead read this with swoosh, which will hit Byleth as swoosh falls. There is still more to be said, but it generally falls along normal MU stuff (ie. How well can Byleth ledge trap Hero, can Byleth kill Hero early, etc...)
Vs.
: This is probably one of the worst MU’s for Ganon, period. Hero can spam zap almost comically easily. I do not joke when I say that it is possible to beat Ganon with only zap, throws, and fair, without even breaking a sweat. Zap beats
EVERYTHING. I am not exaggerating. Ganon has no option that can beat it, nor can he punish it OOS. Ganon simply can’t get it. If he does get in however, Hero can lose very quickly. Ganon can ledgetrap and edge guard Hero reliably with Down tilt and fair, barring zoom. But... that’s about it. Hero can also do that, alongside every character in the game. He can ledgedrop kaswoosh and kill ganon at 20%.
Acceleratle.
I don’t really know what to say about this beyond just, it’s Ganon. Beating Ganon is just something that nearly everybody does.
Vs
: Another decently easy MU. One of the few characters Hero can straight out frame data and combo, Hero hits K rool and doesn’t let him go. Neutral is quite easy for Hero, since crown armor, a usually good tool, is entirely beaten by Zapple and frizzle, some of the most common spells thrown out. When the King does get his mitts on Hero though, he can really dig in and beat on Hero. Heros poor options from ledge allows K rool to abuse him at ledge. However, Hero can do so as well, and edge guard him better. Down air cleanly beats up b, ledgedrop kaswoosh is ridiculously easy, and ledge trapping K rool is predictablely easy.
Bounce is decently easy to find and abuse, krippling the poor kremlin king and his neutral. Acceleratle. Oomph and psych up can be big trouble for K rool due to up air combos. Hero can do a down throw up air, up air, up air, up air for something like 40%
base.
Acceleratle
Overall a pretty good MU for Hero, but with some frightening moments.
Thoughts?
