-Mother Brain's 2nd phase has 18000 health, and in low ammo situations must be defeated primarily with [[Charge Beam]]. In its absense, she requires ammo ranging from 180 Missiles to 60 Super Missiles (the latter number only obtainable in randomizers and other mods). Combined with ammo required for MB1 and the glass jar gives requirements of ammo between 216+0 and 0+76 to get through the fight. Typically seen Missile + Super Missile capacities include the following:

 all of which have 400 damage of lenience. With Zebetite Skip, they allow an approach already from Rinka Shaft using one Super Missile on the door. Loadouts from 100+40 up are sufficient for clearing of doors and Zebetites + a single ammo refill, in the absense of a Zebetite Skip option.

 To completely destroy the jar using one or more Super Missiles is never strategically optimal. This can still be situationally optimal if MB ends up being reached with between 13 and 17 Missiles, between 1 and 5 Super Missiles, and a maximum Missile cap between 20 and 30 — such that immediately backtracking to refill would not provide sufficient ammo for ''both'' breaking open the jar and defeating MB1 in one round. This however implies Missiles were earlier either missed, or used on Zebetites where Super Missiles should have been, at least for purposes of DPS.
-:<small>E.g. 17+5 ammo, with a Missile cap of 20, allows using 17+1 ammo to destroy the jar, then returning after refill to defeat MB1 with 18+4 ammo. This however implies 3 Missiles, and at least 2 Supers, were spent after the previous refill on the approach to MB, to defeat at least one Zebetite. Using instead 0+4 ammo on this Zebetite, followed by 18+0 ammo on the jar, would have been more effective.</small>

 Combinations in red will never come up in optimal play: using ammo to destroy the jar would call for additional Super Missiles having been available earlier, and end up using altogether ''more'' ammo than it would to merely break the jar and defeat MB1 in one go. Put otherwise: any ammo loadout between 8+10 and 0+18 would allow destroying the jar, but since 10 Super Missiles suffice to defeat MB1, the player should simply do this instead. Indeed some loadouts too low to fully destroy the jar but high in Super Missiles, such as 6+10 or 0+16, are seen to suffice also.
