May I ask who do you think is the worst character in game? Samus has okish moves that don't flow together well. Same goes with Zelda.
The question is... what she has going for herself? Is she good at recovering? Okish, but when it comes to landing... Well she cannot land safely. Getting thous % rise? Well she is ok in that. Approaching? Hehehee... Hee... Killing? Yeah... No. Ofc she has her Charge Shot, but it isn't that reliable.
Sorry for my arrogance, but I simply cannot see her above bottom 5. If she isn't THE WORST, then she is 2nd worst character atm. Results eh? She is mostly carried by good players and most of the people lack MU knowledge when it comes to fighting Samus.
Who is the worst character in the game according to me, hmm... That's a tough decision for me. See I can play nearly all the characters in the game decently well, save about 5, so I know standard combos and options for nearly every character. If I had to choose one, I probably couldn't, but I would say the bottom 5 would be Gunner, Sword, Palutena, Zelda and Jiggs, with Ganon and Dedede close by (no specific order, Mii's assumed 1111 medium).
And no, you're not being arrogant, that's fine. I intend to just enlighten you on what Samus can do.
Ok, recovering. Remember recovery isn't just about distance you get with your Up B for example (i'm not implying you meant this, just making myself clear). Samus has multiple options for recovery. Recovery Options > Recovery Distance is usually the case. Bombs to stall fall speed and increase vertical distance slightly (as bomb jumps aren't nearly as useful as before, I find it better to use bombs to help give you a slight boost sideways), a Zair, and an Up B with a hitbox. Tie this in with a great weight, and good aerial mobility and Samus survives longer than most characters.
Landing you are correct with, Samus has a slight issue with this. However, people don't use bombs enough when coming down, and its also just as safe to go for the ledge, which you can grab safely with Zair. Getting off the ledge isn't as bad for Samus compared to most characters. Fair is good, Zair is great, and if you have a Charge Shot, this is great too, and the new shield mechanics only make this option safer than before.
Approaching. Zair. Enough said. Zair is a great option for both approaching and retreating. Literally no landing lag from it makes it relatively safe too. Dash Attack is also decent, as it can cross up shields too. But to be honest, Samus doesn't need to approach. I find Samus much more threatening when you force the opponent to approach, through clever use of Zair and missiles.
As regards to killing, Samus has plenty of killing options. I'll say that you have to be good at using/landing them, but she certainly isn't short of killing moves like in Brawl. Charge Shot, as you mentioned, kills. Not overusing it is key (as with any character really). Fsmash sweetspot kills early, and the sourspot still kills at reasonable percents. Up Smash is powerful and links better than it's ever done before, especially thanks to patches. Bair is also really powerful. The sweetspot is rather big, has good range, and is also relatively safe on shield if it is SHFF, even more so thanks to the shield changes. Samus also has a great Dair, which is very easy to land. It's powerful, and is good off stage. Nair is also good off stage, as it can now kill, and thanks to 1.1.1, is easier to land. And Samus also has a powerful ledge trump game. Reverse Charge Shot and Bair are powerful, and you can even hang from the edge with Zair to trump the opponent (not always the best idea, but its an option, an option not every character has).
People also forget that Samus actually has usable combos. Dash Attach launches at a combo friendly angle. Dthrow works. Uair can string into itself and then a Screw, or you can go Uair into 2 Bairs at low percent. Utilt also works at lower percents if the opponent doesn't tech.
I want to move on to matchups as I finish, as Samus certainly beats most of the characters around her at the bottom. Ganon and Dedede for example. In general, Samus has a better matchup spread than most characters at the bottom, being able to compete with lots of higher up characters like DK, Bowser, and even high tiers like Falcon and Luigi, who the latter is considered to have a disadvantageous matchup to Samus. No other low tier has this distinction.
Samus has a few hitbox and moveset problems, and its due to this that people who know nothing about her just label her as the worst character in the game. I usually get "jab doesn't link, it sucks". Well why use Jab when you can use Dtilt, which is much safer? Samus has plenty of kill options this time, so people saying that she has no killing options are very naive.
I don't want to come across as saying Samus is a fantastic character, no. She still has a few things that could be tuned up, but what she has currently works, and is certainly not at the bottom of the tier list. All this is just one way to play Samus. A lot of her moves can set up tech chases. If you have miss a tech against a Samus with a Charge Shot, you may be on the receiving end of one.
