I could make a tier list sure. But wouldnt call it the consensus yet, cause we're not all the knowledge there is about this subject. We're simply the only ones left. I miss a lot of old faces here who had great arguements for certain characters.
If I had my saying I'd make my tier list like this:
SS Tier: Basically untouchable by most of the cast.
*
Am not too knowledgeable about Bayonetta however. I've done a little research and it seems she belongs somewhere high. Not sure how she'd fare against the others here, but am sure she beats anyone below.
Mewtwo, Samus and Sonic also stomp the rest below easily and each would give the other a tough time. Personally I say Mewtwo beats the others, but it's all very close.
Some further explanation why these characters deserve SS Tier placement:
Regular Mewtwo alone deserves a placement over the rest purely because of his natural learned moveset. It just gives him so much to work with, he easily hacks his place up here with that alone. Psychic powers are mostly always regarded as the most powerful and useful 'super power' in just about any universe. Mewtwo proofs why. And this is with careful consideration. First of all, he's extremely adaptable and intelligent. So that gives an edge.
But with given restrictions, Mewtwo isn't as flexible as it looks like. Four Move Limit is a damn curse in this regard. But ironically, Mewtwo is versitile and powerful enough to even with with these restrictions. He's got Mega Evolution to help boost his offensive powers whenever needed, Recover, Calm Mind, Me First, Psystrike, Protect, Amnesia.. Let not alone release the beast of RBY Mewtwo ; Amnesia, Recover, Psychic / any move you like...
Mewtwo is all incarations of any generation is an awful beast that nobody wants as an enemy. He can float, stall with teleporting and Recover / Calm Mind to set up.. He has different Mega Evolutions to boost physical of special attacks... He's basically a Dragon Ball Z character, no joke. He could probably beat a couple of them as well. It all depends on what restrictions are applied, cause with Pokemon there's a lot to consider. Does he lose TM moves cause NoTrainer? Does he keep Four Moves Restriction? Or does he have acces to all moves naturally learned by leveling up (this seems the most logical). With full restricitons, I still say he beats Samus. It's just the other stuff that he needs to deal with Super Sonic, and especially Bayonetta. The rest of the cast cannot touch him even with restrictions.
Wild Level 70 Mewtwo is probably about B tier however.
Chaos Emeralds, Super Sonic, able to move super sonic speeds... Need I say more? Am no Sonic expert. But he belongs here. Regular Sonic is beatable, Super Sonic is like Mewtwo, a Dragon Ball Z character. That's the best way to describe them. Easily makes him beat everything below. The only matchup he should fear are Bayonetta, non restricted Mewtwo, and Samus.. Well, she also runs super sonic speed. Would be a very interessting one.
Regular Sonic is probably about A- Tier i imagine?
Samus doesn't joke around. While she's not an absolute planet buster directly, she's a highly trained one woman army. Intergalatic one woman army. She gets paid to let humanity survive. She deals with high intelligent alien species on her own, has extremely powerful weaponary and has far above super human agility, durability and strenght. She fires stronger shots than a whole futuristic army, runs as super sonic speeds with Speed Booster. Hyper Mode in Metroid Prime also doesn't joke around... Diffuse Ice Missiles, Screw Attack, Power Bombs, all her types of beams and missiles. How doesn't she earn her place here?
Apperantly a destroyer of Gods, demons and angels. Not a friendly one this lady. I need to do more research, but she seems extremely powerful.
S Tier: Extreme powerhouses
*
Planetary levels are still reached here. These guys (and girl) could easily take down a Arwing. Think thats quite an acchievement. These fighters all got insane feats and equipment (especially the case of Meta Knight and Pit) that puts them higher than the rest. Some argued Kirby to be God tier, I say the puffball is a little too frail to be up there. But these all could indeed hold a fight against the SS Tier and not go down shamefully I'd say.
Also maybe Shulk belongs here too? Not sure if the powah of the Monado is enkugh to bring him here.
New Adition: Rosalina and Luma.
Added Rosalina to the S Tier because of her feats in Mario Galaxy. She's a sort of cosmic guardian of the Mario universe. So that and surviving the universe's collapse and being able to create black holes puts her up here.
New Adition: Bowser
Bowser also gets here, but he actually shouldn't be up here considering he is destined to be beaten always. Mostly by story purposes however, or a special Mario-only power up. He should be considered of a lower power level than most of the others, but his phenominal strenght easily makes him deserve this tier. If we go by Bowser's Inside Story's Bowser, the Giant Bowser from that game poses enough trouble for even the SS Tier. Considering this, he might actually be higher up, but story purposes and overal bad strategy makes him lower.. He's bound to Bad Guy Syndrome.
New Adition: Dark Pit.
He benefits from Pit's placement. Because that's only logical. He'd probably be somewhat weaker overall, but the matchups Pit wins, Dark Pit wins. And they are close enough in power to share about 90% of matchup results.
S- Tier: Super Heroes Tier
Mario is an interesting guy. He's bound by the Good Guy Syndrome. He's sort of destined to meet any challenge. But he lacks extreme feats, and is often heavily reliant on team work. He does have a lot to work with however, depending on which game you chose his abilities from. So he's pretty damn versitale. He's atletic and jumps very high and his stomp is mighty. Then he also got Mega Mushrooms and tons of other power ups. Could maybe even win matchups from characters higher up than him, in fact, Bowser is ranked higher and Mario beats him. So there's that.
Luigi is up here cause he's at least equal to Mario. Or is he? He doesn't know... I don't know. You don't know. But don't underestimate him. The perfect Element of Surprise.
He's bound to be at leat equally as strong as Mario, and is also heavily versitale. And above that, extremely powerful, as he can singlehandly punch a huge comet serving as the Moon down to his enemy's face. He easily adapts to any sort of enviorment and he's a terror up close. Donkey Kong might actually be the strongest character of this tier, am pretty sure. Mario vs Donkey Kong sort of shows how Mario cannot beat DK straight up in a fair fight... In Jungle Beat, DK is an absolute beast that tears down enemies 10 x larger than him in a heart beat, a violent an swift heart beat. He cannot handle super natural abilities well I imagine, so that's why he loses to the upper tiered characters. That's why he's placed here. In King of Swings he also has the abilty to heal through bananas and invincibility with crystal coconuts.
I will admit, Diddy barely makes it here but he's well deserving of this tier placement overall. He's weaker than Donkey Kong, and that's mostly due to DK making a solo appearance in Jungle Beat. But Donkey Kong doesn't rely on that appearance alone for his placement. Like Luigi benefiting from Mario's placement, so does Diddy here. He wouldn't win a fight with any character mentioned above. But he would win from character's below. And that's cause he's able to hold his own against the Star Fox crew I imagine. He's also like DK extremely adaptable to natural enviorments, always finding weapon to work with.
He's got Orange Grenades for the explosives, the Barrel Jet with Peanut Popguns to hold an aerial fight, and healing abilities with bananas due to King of Swings, as well as invincibility with crystal coconuts. That makes him win the aerial fight with the Arwings. As well as his projectiles being sort of leaded missiles, he will hit more often and can endure hits with healing and invincibility. If the Arwing crashes and the fight continues on land, Diddy has the obvious egde. Unless a Landmaster is also available? I doubt it, but if it arives it could take time, which Diddy could optimise.
Anyway, Diddy holds his own. His overall matchup results would make him deserve his placement. Even though it takes longer for him to defeat his enemies because he relies on equipment and atletics mostly and not strenght like the rest. Even with that considered, looking at the attack patterns of the DKC2 bosses and given Diddy dodges direct canonball fire, who's to say anything can easily hit him in the first place?
Cloud should probably belong somewhere around here.. But I know next to nothing about him. So this is a honorary position.
(Hero of Time)
What can we say about Link? A lot. I put him down this high mostly because of his Ocarina of Time appearance. But I think many other Link incarations deserve to be up here too. I say definitely the Hero of Time should belong here because of his magic arsenal. Nayru's Love and Light Arrows are powerful stuff. I think he might just beat Diddy, but not the others. Breath of the Wild Link also deserves a mention and to be ranked up here I guess, as he also does cool tricks and is highly adaptable. I think if you can destroy several Guardians with ease, you can handle Arwings. Anyway, that guy is not in Smash as of yet. Link of the Past Link, shout out to you too. Or are you a Young or Toon Link? Anyway, the Hero of Time seems his strongest incaration, so there he is.
I'll probably adress the other Links who made an appearance in Smash individually as well. Those be; Young Link (OOT / MM) Toon Link (WW) and Twilight Princess Link.
(Majora's Mask)
Yeah didn't think that last part through. Anyway, you know of Fierce Diety Link? Yes? Okay. Well that's the only actual reason that Young Link from Majora's Mask is up here. Might actually be stronger than the rest of the tier. I could see him beat Kirby, Meta Knight and maybe others.. Could he beat Mewtwo and Samus? He seems like a contender... For now, he's ranked here.
He's regarded as the most powerful Hero in his lore. He's the Goddess slayer of Telius, the Hero of Blue Flames, leader of the Greil Mercenaries, Ike. If we take his blessing from Yune literally, not many would be able to even hurt him. He'd maybe lose to Fierce Diety, but unless you carry divine blessing, Ike ain't touched. So along with DK, I say he's leader of the tier. He'd take down Palutena easily. And also Pit most likely. But he loses to the rest.. Maybe.. He could take Lucas. Aether ain't nothing to mess with either! With Ike, you need to beat him swift before he beats you. The longer it takes, the better for him, as Aether will probably be a game changer.
Placeholder...
S-- Ganon
The Great King of all Evil, Ganondorf. Yes I rank him this low because he's losing to the divine and psychic abilities of most of the cast up here. He will probably beat DK and Diddy in the upper tier, but they instead beat others that Ganondorf cannot handle. I put him in a special lower Tier because he would also probably lose to characters from the Fire Emblem cast. They seem very specifically equiped to handle Ganondorf, but he does beat Arwings. Still, considering how Ganon is one entity, I can say with Breath of the Wild's Ganon that Ganon can be beaten with weapons that are not exactly "blessed". That's why he'll fall to Samus's beams for example, and Mewtwo and the MOTHER kid's psychic abilities. Super Sonic and Bayonetta also beat him, and so do the Mario Bros., Rosalina, Pit, and many others. He'd probably beat Palutena however due to sheer force. And if you wanna go game mechanics, maybe his Dark type magic is super effective against Mewtwo?
A+ Tier: Zero Suit Samus
She still has acces to the beams of regular Samus and the Screw Attack in some of her playable appearances. If we go soly by Metroid Zero Mission ZSS, she drops drastically. But with the Screw Attack and beams alone she should be good. IF we use creative liberty of Smash, we can argue she can use the Grapple Beam as well thanks to the whip-gun-sword in Smash, but I still stand convinced that Screw Attack and Beams is enough. If minimally equiped, expect B- tier or so.
A Tier: Elemental Animals and Wizard
Came to a new conclusion that these characters would all rank togheter very nicely. Robin has story related mechanics that make him very interessting, but his 'Robin' incaration seems pretty defeatable. Still, he's got lots of skills that help him. And magic like Nosferatu. He can change classes, so that would make him very hard to handle for the rest of the Fire Emblem cast, except for Ike.
Now the Pokemon cast. These are all extremely powerful Pokemon in their own right. All have a stronger form, even if Greninja cannot Mega Evolve, there's this Ash Greninja who got stat buffs. Charizard X and Y and Mega Lucario are also not to joke with. They enjoy a lot of gimmicks due to Pokemon hax, but not quite enough like Mewtwo. Still, the matchups he wins outrightely are also probably in advantage to them. Mostly with Lucario and Greninja due to speed. However, I expect Mega Charizard X with enough time to set up Dragon Dance able to tear down anything in this tier.
A- Tier: Basically Arwing Tier
These guys are intergalatic mercenaries and gangsters. Well trained and armed, expect them to be able to deal with a lot of **** handled at them. Don't have a lot of defensive abilities except for barrel rolling, but their fire power is strong. Being airbone gives them the edge above the other characters below. However, the Landmaster of Fox and Falco (and since Brawl, also Wolf of course) would still give a whole lot of trouble.
A-- Tier: Pika Tier
Pikachu in his own tier. Why? He's a glass canon. Hits hard but cannot take them. That's why he loses to everything up here, but he's at least able to take down a lot of their 'HP' before going down. Thunder Wave paralysis also gives a lot of trouble. Pikachu is simply a treat that needs to be dealt with as quickly as possible. His lightning would be able to take down the Arwings, but the Arwings are overall more durable thus placed higher.
A--- Tier: The Blue Falcon
He just drives... A very fast car. He basically can do infinitive Final Smash against everyone below, because he just goes fast. What a cheater.....
B+ Tier: The Hero of Winds and the Hero of Twilight
Master Sword and Light Arrows carry you places. He's weaker than the Hero of Time, and lacks his magic, but he's more equiped than the Fire Emblem cast below. Versitality wins here, plus his Boomerang is nasty. Am convinced he's still worthy of this placement.
Toon Link might have Light Arrows, but this more adult and realistic version has Bomb Arrows and a whole lot of secret sword tricks to compensate. I say in physical strenght alone, TP Link stomps Toon Link. But we cannot ever know this for sure. They both beat Ganondorf with the help of Zelda. I say they are pretty damn comparable. All depends on if Toon Link is able to hit with the Light Arrows... Which should be hard as TP Link as an edge in sword fighting, and the arrows can be reflected with a shield.
B Tier: Fire Emblem Heroes
*
Corrin might rank higher due to dragon insanity, but I know next to nothing about Fates. So I rank Corrin here as a place holder mostly.
Doesn't matter all too much cause Marth and his upgrated alternate costume clone and DLC semi-clone have weapons that are especially powerful against dragons. Noticed that Fire Emblem Heroes reference? Well that's exactly what has been happening a lot in my playthroughs. So Corrin might be stronger to the rest of the cast, but they get beaten like a pulp by the rest of the tier.
Marth deserves special status due to FE1 Falchion hax. If we count that, he goes higher up. There's also the Dark Orb, and the Shield of Seals that give him a lot. Anyone played FE12? You should. Cool game.
Lucina is probably a lot stronger than the others if we go by recent appearances. She might potentially be near-Ike level. But she likely loses to the same matchups and loses a few more because no Yune blessings. Still, she's not one to take lightly. Should be with Robin sitting higher, but with her sword alone she cannot easily deal with the technological advanced characters up. She does beat Pikachu and maybe the other Pokemon however? Mega Charizard X wouldn't like to meet Falchion am sure... Lucario and Greninja are a different story.. She might get a promotion later on. Do think she can beat Ganon however.
Roy has the Sword of Seals. It's a very strong weapon you know. Shoots fire and kills dragons. Not too impressive? Well he goes and defeats a whole lot of ancient dragons with it. And he beat Zephiel in canon. From all the Fire Emblem units he's probably the weakest overall.
B- Tier: Team Underdog
