			The shots from the turrets are able to collide with missiles and super missiles in ways that can be unexpected. This is because enemy projectiles and Samus' projectiles detect collisions with each other based on whether or not they're in the same 32 pixel x 32 pixel grid, rather than whether the two hitboxes collide.

	If Samus is struck by a turret shot, it will produce a cloud that lingers in the air for around a second. This cloud can consume a Missile or Super Missile if one comes in contact with it, which is more reason to be careful when firing at MB1 in lower-percentage categories. There is a group of white pixels that will appear in the air as long as this cloud is present.

	After MB1 has been defeated, the screen will scroll directly onto Mother Brain so she can begin transitioning into her second phase. Although you can minimize the time the game spends scrolling the screen by being closer to Mother Brain right when the scrolling occurs, doing so does not save time as Mother Brain will always take approximately the same amount of time to transition regardless of the time spent scrolling the screen.

-If you are above a certain threshold after the first rainbow beam, Mother Brain will fire shots at you until you're below that line, possibly including additional rainbow beams. For Gravity Suit this threshold is 100, for Varia Suit it's 180, and for Power Suit it's 340. It's possible, though rare, for Mother Brain to kill Samus during these additional damage-down shots under certain conditions. The most common death scenario is when Mother Brain drops a bomb when Samus is between 101 and 120 health, then shoots a volley of two rings. The bomb hits for 40, then the rings hit for 20 each, then the bomb can double-hit with its explosion for 20 each.

The reason why the resulting swifter cutscene happens is related to Mother Brain's head. How it shifts during the cutscene directly determines how long the cutscene takes.

	The "more forward" foot position ~~seems~~ to ~~only happen~~ when Mother Brain steps slowly backward before firing redbeam.		The "more forward" foot position was theorized to occur when Mother Brain steps slowly backward before firing redbeam. Observations made in April 2022 by ShinyZeni and ProfessorSchool suggested that Mother Brain's behavior could be manipulated to force the "more forward" foot position. The required manipulation is performed during Mother Brain's second phase when her health is reduced below 25% and the redbeam ability is gained. For the manipulation to work, the damage that puts Mother Brain below 25% must occur as she is stepping forward. After taking this damage, she will step backwards. If the manipulation worked three things will occur:

	~~Below is~~ a ~~comparison of various [[Tool Assisted Speedruns\|tool assisted speedruns]]' cutscenes~~ to ~~demonstrate~~ the ~~potential difference in speed~~.		1) Mother Brain will step backwards and her foot will be in the "more forward" placement. <br>
			2) The length of the backwards step will be abbreviated from a normal 13 frames to 3 frames, making it easy to notice. <br>
			3) Mother Brain will sit down approximately 3 seconds earlier in the ensuing cutscene than if no manipulation was performed.

			The manipulation is demonstrated in the video below.

	The reason why Cpadolf's 100%, in particular, is so much faster than the others is because Samus is able to influence Mother Brain's head movement, independent of her prior foot placement. Saturn's GT Classic would have been able to do the same, but did not influence her as effectively, as perhaps it was not known at the time that it was possible to do so.

			Being airborne, for example using Space Jump, then landing at different times while the Baby is draining Mother Brain's energy, will impact the length of time it takes for Mother Brain to crouch during the cutscene. Specifically, being airborne before Mother Brain turns blue, and landing shortly after blue Mother Brain begins walking forward appears optimal. Landing later or staying on the ground throughout Mother Brain's transition to blue each result in an extra 1-3 seconds before Mother Brain crouches. This was tested empirically and is demonstrated in the video below.

	For categories where the player is unable to perform the Standup Glitch, the primary factor that will determine how quickly Mother Brain will crouch down is actually her foot placement. If Mother Brain's foot is placed a few pixels more forward compared to what is normal, this will cause her to spend less time being attacked by the Super Metroid before crouching down, thus resulting in a swifter cutscene.
