It is possible to kill all Zebetites except the first using precisely 10 missiles.

Zebetites have exactly 1000 health, and missiles deal 100 damage. Usually, Zebetites gain health for every frame they are on screen. Thus, one would initially expect this is impossible: Even if the Zebetites are manipulated to be on screen for as little as possible, they will still be on screen for some finite amount of time. However, Zebetites do not gain health for 5 frames after damage has been dealt. Thus, if a Zebetite is moved on screen for fewer than 5 frames, its health will never increase.

Therefore, by carefully manipulating the screen position, it is possible to: (1) Fire a missile while the Zebetite is off-screen, (2) move the Zebetite on screen for fewer than five frames while the missile hits; (3) repeat with remaining missiles.

==Current best RTA setup==

The current best RTA method for this is the following:

{{#ev:vimeo|652937875}}

This involves the following steps:

(1) Initially setup the camera to be as far away from the Zebetite as possible.

(2) Moonwalk back to the correct pixel.

(3) Moonwalk back one additional frame: If Samus does not move, good; if Samus moves, then walk (or roll) back right and start over. The goal is to get onto the back half of this pixel, so in step (2) when nearing the pixel you should attempt very small moonwalk movements.

(4) While facing right, crouch, turn-around, jump, and turn-around in the air.

(5) Repeat step (4) two more times.

(6) While facing right, crouch, turn around.

(7) Fire a missile, jump, and turn-around: There is a five frame window for this turn-around. If successful, you should hear the Zebetite get hit.

(8) Repeat steps (1) - (7) for all remaining missiles.

Since this is about very precise camera manipulation, any other movement (other than vertical movement, like jumping or morphing, or movement you can undo, like turning around) will mess up the setup. If the Zebetite has not been moved on screen, you can move back to the right and start over at step (1).

In particular, getting hit (by Rinkas or turret shots) will very frequently jolt the camera left and back very quickly: This will usually move the Zebetite on screen briefly, and thus will usually ruin the attempt. Thus, this entire very slow method has to be done basically without getting hit by any Rinkas or turret shots.

It should be noted there is a faster setup, without the dancing in steps (4)-(5). It requires moonwalking back to the correct pixel (a different pixel than what one ends up on after dancing). The issue is that you must be on the front half of the pixel, which is harder to recognize. The above method was developed to maximize the frame window for firing the missile while also allowing for all cues to be entirely visual.

==Double kill==

The above setup works on all Zebetites.

However, the second and third Zebetite can be double killed. This is accomplished by hitting the second Zebetite after it has died, but before it has exploded. What you hit the Zebetite with can be any projectile: In particular, it can be a beamshot.

Thus, while killing the second Zebetite, you should repeat the setup for an eleventh shot of a beamshot. This will then kill both Zebetite 2 and 3.

==First Zebetite==

The first Zebetite cannot be moved off screen, so cannot be killed in 10 missiles.

==First and last shot of the kill==

In theory, the first and last shot would not need the full setup.

For the first shot, it doesn't matter if the Zebetite is on screen beforehand. Thus, in theory, one can fire the missile with it on screen, and then quickly move it off screen. A setup would have to be developed.

For the last shot, it doesn't matter if the Zebetite is on screen afterwards. Thus, in theory, one can fire the shot with it off screen, and then just run to put it on screen as the shot would hit. It was attempted to find a good setup for this with a beamshot (for the double kill), and it seemed to fail more often than the complete setup. However, this could simply be due to improper timing.

==13%: The major consequence==

The major consequence of this method is that 13% with (Charge, X-Ray) as a base is possible. The above clip is of a segmented run for 13%, confirming this to be the case.

This 13% category requires L+R.

This could also lower the percent of any low% category allowing L+R, e.g., low% RBO.

==Minor Consequences==

If L+R is not allowed, this opens up a couple new 14% categories. These are:

* GravPb: (Charge, Gravity, Power Bomb). Use a Puyo to get a power bomb drop while CF clipping to Botwoon. Use this method to get past Zebetites.

* xGravity: (Charge, X-Ray, Gravity). Use R-Mode for pre-Botwoon. Use Gravity for the rest of Maridia. Use this method to get past Zebetites.

* xGrapple: (Charge, X-Ray, Grapple). Copy the 13% method, but use Grapple in Mt. Everest and Halfie Climb Room.

* xBoots: (Charge, X-Ray, Hi-Jump Boots). Copy the 13% method, but use underwater wall jumps instead of L+R.

* xSpring [PAL]: (Charge, X-Ray, Spring Ball). Copy the 13% method, but use mid-air spring ball jumps to climb Halfie Climb Room. Getting to Spring Ball under these conditions requires G-moding from Aqueduct. Getting to Aqueduct requires crossing Mt Everest. To Jesuswalk Mt Everest on NTSC requires L+R. Thus, this category is PAL-only.

* Gravboots [PAL]: (Charge, Gravity, Hi-Jump Boots). There is a PAL-only method to get past pre-Botwoon with Gravity, Hi-Jump Boots, and a Reserve Tank. This is used there. Gravity is used for the rest of Maridia. The above method is used for the Zebetites.

+==Current best RTA setups==
-The current best RTA setup is as follows:
+The current best RTA setups on NTSC and PAL are very similar. They involve taking a hit by a Rinka (to avoid the turrets sniping during the setup), performing a quick mid-air morph and unmorph (to be in unmorphed state before hitting the ceiling:  You cannot aim down before the ceiling), downbacking onto the Zebetite platform (making sure to downback into the wall to keep the positioning normalized), and then turn-around spin jumping to the left.

+The final parts of the setup are different on NTSC and PAL, in order to get to the correct screen position. See the below videos to get the precise steps.
-This is on PAL. You can get this setup to work on NTSC by dancing on the pillar you jump right onto, but then the turrets have a lot of time to shoot you so it's pretty RNG dependent.
+After the setup, the process is again the same:  When crouched on the ground facing right, turn left and fire a missile, jump in the air, and turn right in about a 3 frame window. Then jump in the air, turn left, and turn back right on the ground to get back to where you started. Repeat.
-The setup is as follows:
+===NTSC Setup===
-(1) Initially moonwalk left to scroll the screen as much as possible. I am unsure how much this is required, but it does move the left turret off screen which helps.
+{{#ev:vimeo|789322973}}
-(2) Make sure the Rinkas are in a favorable position. Shooting the bottom then the top as quickly as possible works.

-(3) Run into bottom Rinka just before it hits you.

+This also simplifies analysis of low% categories, in this and rom hacks that do not significantly modify Mother Brain. Specifically, Mother Brain 1 needs 20 ammo, so 10/10 ammo works. It being possible to defeat the Zebetites with only 10 Missiles means that no special consideration needs to be given to the Zebetites. This means if you are thinking about something like low% RBO or low% map completion, you can ignore the Zebetites.

 However, if you mess up the first jump, you will be far to the right. It will be difficult to get back left without accidentally moving the zebetite on screen.

	Note getting hit by the Rinka takes 220 damage, if going for the double kill (and you have Varia but not Gravity). This means you either need two Energy Tanks for this setup, or you need to use some reserve health. Getting hit by the Rinka is not actually necessary, so you could skip it. But then on the jump over and back, you can get hit by turret shots. So it is more dangerous to skip it.

		+	It should be noted that getting hit by the Rinka is not actually necessary for this strat. With the Rinkas well-positioned, you can simply jump over them and then jump back.

If you want to run 1+2 Energy+Reserve Tanks, then you could do the first couple of missiles without taking damage and then switch over.
