Time for natsu. Sorry this may be long, I like to do everything in depth and a short bullet point list just won't do for our ninja princess. Natsuloverxoxo ^_^
Natsu
Play style- speed, punishment, wall/ring out pressure
Execution- medium/high. A:6 and PO a:6 are essential. Some -10 a:6punishes are difficult and getting a consistent i8 4a+ba is demanding as well.
Pros- speed; fastest AA in the game at i10 with a B followup for 48 damage. i10 a:6 for punishment, knockdown/ring out/wall splat. i8 4a+ba and 2Ba for interrupts and interesting frame traps. Also guaranteed on 2a hit and PO B block.
Damage- her wall damage is insane with her standard combo, mid screen damage is respectable off of 3b, bomb combos, 22a ch, and 66b/BE
Wall/RO pressure- once you have your back to the wall she can herd you and fish for a ch 22a for the ring out. Blocked 22a leads to reverse mixup where a good read can put you out just as easily. Step after a blocked 22a eats an a:6 or ch Aab. Has a variety of moves to ring out with from all angles.
Jg game- with a:6 almost any move on just guard can be punished for chunky damage. It may to be as high as a stab from the Pyrrhas but the frequency with which you can land a:6 makes up for it.
Evasion- natsu has a great variety of tech crouch/step/jump moves. 22a both tech crouch and tech step and leads to good reward on hit and great reward on ch. 66b can go under and around most AA and BB at slight negative frames(-4 to-6) leading to nice damage with ch bonus(pray for clean hit). 3b has a nice tech crouch and tech step on it, has some specific uses such as in the pat matchup after blocked 236 a it will punish raw 236 a and interrupt the b for mid air a:6 combo. Great tech jump moves in 8ka( big damage, confirmable, 8k only -4 on block). a+b far reaching knockdown with reverse mixup on block, and 8a mid knockdown push out move. Also has 3_9 b+k to get away from ring edge pressure.
Cons- can be zoned fairly easily. Has a hard time catching good backstep at range 2 or beyond. Has to commit to 66k which is -16. Only advisable to spam in certain matchups with weak punishment.
Poor throw range. Have to be right up in their face to attempt a throw. Compound this with the fact that against characters like nm and cervy who shrink their hurtbox when they guard and it can be frustrating to land throws. Kind of on the same note natsu extends her hurtbox when she guards so she can be thrown from further away than her neutral stance. A throw without meter does 38 damage so a person committed to breaking b has to eat 7 throws in a round to be killed unless you want to burn meter.
Some may not agree but I would argue poor lows.
1k has abismal range compared to many other characters 2k.
2kk is decent but slow for a poke and can be jg'd on the second hit with practice, poor tracking as well.
1a should be blocked on reaction though it does have merit for super tc, range, ring out, and hard to punish when spaced at max range.
Bombs should be blocked jumped on reaction so their use as a mixup is 0, they still prove useful as oki/step/block punishes due to the damage potential.
4a is an insane round ender that is fast, doesn't suffer guts system, tracks to one side and has the PO brave edge if they block it. Outside of ending rounds though its not terribly good. Some characters (natsu with 66b and apat with 3b) have a universal move to beat all options post 4a hit. Failing that other characters can backstep and do a tech crouch move and deal with most options that way.
PO b+k is slow since you have to do the PO transition to access it, doesn't track well, no range. Nice damage and ring out though, decently safe if blocked.
11a is decent in that it has range and is hard to see. Still not very fast so can suffer ch. Meh damage that suffers from guts. If opponent gets ch during a TC move you won't get the knockdown and instead can be punished for landing a CH.
Combine the poor lows and poor throw rage and it can be hard to get an opponent to duck for her nice mids. She has great frame traps to cover this and ok guard damage game with po b, 8a+b, 6ka among other things.
In conclusion she da bes.
