Jump Guardian

Dark Samus 1

Power Bomb Method

If you already have the early power bomb from Temple Grounds, then Dark Samus can be killed in one hit with a power bomb. The most consistent method is to morph immediately when the fight starts (without pressing any direction), then roll to the left and around the center pillar until you roll into Dark Samus. Plant a power bomb just as you touch her, as she will use her force field attack and stay in place.

No Power Bomb Method

If you did not get the early power bomb, or are doing 100%, then you will have to actually fight Dark Samus.

The best way to deal damage is to repeatedly use fully charged power beam shots. As the power beam travels somewhat slow, you want to stay close to dark samus as much as possible.

Dark Samus will almost always use her force field when a missile is fired within her vicinity, or if Samus herself is almost touching Dark Samus. This is very useful for manipulating her AI and making her stay still. Occasionally, the missile will actually hit Dark Samus, stunning her and dealing damage, which is good. By manipulating her to put up her force field, she stays still, giving enough time for you to charge a power beam charged shot and hit her before she jumps away.

In the first phase of the fight, stay close to Dark Samus as much as possible, as you want to avoid using missiles because they do waste time; only use missiles if Dark Samus is far away. (If you have trouble staying close though, then feel free to use missiles).

The second phase is where missiles become important, as Dark Samus has two attacks where she is completely invincible for several seconds. You want to constantly make sure she has no opportunity to use these attacks by firing a missile at her, then shooting a charge beam, then shooting a missile at her again to keep her in place, and so on.

Grapple Guardian

Phase 1

First scan Grapple Guardian. You can't lock on to his eye if he is not scanned.

Three normal light beam shots in the eye stuns Grapple Guardian. When he is stunned, strafe around him, and shoot his back with a fully charged light shot. Try to sneak in a few normal light beam shots on his back while he slowly turns around after the charged shot. Then repeat; this round should go down in 3 sets of attacks on his back, if done properly.

If Grapple Guardian attempts to grapple you, then let him grab you and shoot a single normal light beam shot into his eye. This will instantly stun him, and you can damage his back more quickly.

Phase 2

Phase 2 starts when Grapple Guardian goes into an animation where he roars in pain and loses the armor on his back. While waiting for this animation to end, you can use a power bomb to blow up the gate at the dark door as you generally should be leaving that way.

Try to stay close to his front to manipulate him into try to attack you with his horn. You want to avoid him using his grapple attack, since if he grapples you and you stun him, you can't damage him for several seconds. If he does grapple you, let him reel you in and hit you, as it's faster than either letting him miss repeatedly, stunning him, or letting him grapple a pillar. Of course, don't do this if your health is low.

Stun him with three shots in the eye again. Immediately after the third shot, charge your light beam and hit his eye with it as soon as possible. Usually he will have a sliver of health left; if you were fast enough, you can sneak in an extra light shot or two to finish him off.

After Grapple Guardian is dead, morph near his body as the game warps you by where Grapple Beam spawns anyways, and when Samus is morphed, all of his drops move towards Samus in this part of the game.

Dark Samus 2

You should be fighting Dark Samus 2 in 100%, as echo visor is skipped in any%.

This fight is mostly straightforward. Charged Dark Beam Shots are key to defeating Dark Samus 2 as quickly as possible, as she is weak to dark beam (ironically), and charged dark beam deals much more damage if the chasing ooze hits her as well. As such, try to stay close to her to manipulate her into using her force field attack so she stays still while you hit her with the charged dark shot (meaning the ooze will damage her).

If Dark Samus morphs, use a charged dark shot to break her out of her boost attack (you can only do it AFTER she's done morphing).

Every time Dark Samus returns from Dark Visor Mode, when she's in the air, shoot a charged dark shot the moment she lands. She is vulnerable at this moment, and standing still, so the ooze damage can deal extra damage.

Quadraxis

Quadraxis can be skipped by wallcrawling past him.
