Introduction

The damage of an enemy means the amount of damage contact with the enemy's body will deal to Samus. For damage values on this page, "P" stands for Power Suit, "V" stands for Varia Suit, and "G" stands for Gravity Suit.

The damage values for enemy attacks and bosses are currently not listed. Check out the Damage Sources page for that information.

For Space Pirates, the word in parenthesis further indicates the kind of Space Pirate it is. For Tourian, "All" means that the data applies to any of its kind (standing, wall, fighting).

How Drops Work

To make understanding this information easier, item drops will be explained as existing within the following tiers:

  • Tier I - Small Energy, Large Energy, Missile, "nothing"


Tier I items affect whether each other item in Tier I will drop proportionally to the size of their drop rates. For example, a Waver has a 2%, 24%, 24%, 24%, 24%, and 4% chance to drop nothing, a Missile, a Small Energy, a Large Energy, a Super Missile, and a Power Bomb respectively.

If you are full on Missiles but are not at full energy, the drop rates will change as follows:

  • Nothing - 2% -> 4%
  • Small Energy - 24% -> 35%
  • Large Energy - 24% -> 35%

The 24% chance was distributed at a ratio of 2 : 11 : 11.


If you are at full energy but are not full on Missiles, the drop rates will change as follows:

  • Nothing - 2% -> 4% -> 6%
  • Missiles - 24% -> 46% -> 68%

The 24% chances were distributed individually at a ratio of 2 : 22.


Tier II items can also affect the drop rate of Tier I items. Having full Super Missiles or Power Bombs will cause their drop rates to be evenly distributed through Tier I.

For example, if you are full on Super Missiles but are missing both energy and Missiles, then kill a Waver (drop rates referenced earlier), the drop rates will change as follows:

  • Nothing - 2% -> 8% (+6)
  • Missiles - 24% -> 30% (+6)
  • Small Energy - 24% -> 30% (+6)
  • Large Energy - 24% -> 30% (+6)
  • Power Bombs - 4% -> 4% (+0)

The chance for Power Bombs to drop will not increase as unfortunately, the chance for Tier II items to drop cannot be increased by any means. For example, if you are full on everything except Power Bombs and kill a Metroid (which has a 12% chance to drop Power Bombs), that 12% chance is not increased - effectively, everything is converted to nothing. Ultimately, the drop rates for Super Missiles and Power Bombs are constant - they are not affected by Tier I, but can affect Tier I as explained previously.


If an enemy does not have a chance to drop "nothing", then the drop chance will be directly converted (spread) between items. For example, if you killed a Zeela while at full energy but missing Missiles, then the drop rate of Missiles would change from 50% to 82%. In that scenario, if you were full on Super Missiles (or had not yet obtained them), then the drop rate would instead become 102% (100%).

The specific drops that spawn are determined on the frame the enemy's explosion animation occurs (or in the case of bosses, the frame the drops themselves spawn). This information is only reasonably useful for tool assisted speedruns where you have the ability to manipulate drops by killing an enemy on different frames until it drops what you want.

Bosses can only drop a maximum of seven Super Missiles or Power Bombs, and having a boss spawn seven of either is extremely rare. Bosses are not capped in terms of how many energy or Missile drops they can spawn; however, certain bosses are incapable of dropping small energy upon their defeat.

Bosses will drop "nothing" if Samus has full energy and full Missiles on the frame their drops spawn; otherwise, bosses are incapable of dropping "nothing", and being capped on one of either energy or Missiles will cause the drop chance to entirely roll over to the other.

In the event that your energy goes below 30, it will cause all enemies in the game that drop items to attempt to provide you with energy instead of any other drop until your energy goes above 50 and another drop is generated.

If you receive an energy drop that puts you above 50 energy, but then dip below 50 energy again (even if you dip below 50 energy but not 30 energy) before the next drop is generated, you will still receive energy as the next drop. This is because the game only changes the flag for energy drops upon a drop being generated.

Although the low energy alarm does begin at 30, the game will not force energy drops upon you until it goes below 30.

The amount of items that certain enemies will drop changes depending on how they are killed. For example, if you destroy a Geruta, a Magdollite, and a Metroid with a Power Bomb, they will drop up to two items, three items, and one item (instead of up to one item, one item, and six items) respectively. These are the only cases of death via a Power Bomb causing a different amount of drops than the typical amount.

Finally, here is an explanation of drop generation by itsblah using hexadecimal values.

Why is the drop rate out of 102%?

The game stores nearly everything as a hexadecimal value and the drop chance for an enemy can have 2 characters at most. Theoretically, this means that if an enemy were only able to drop nothing, the chance of it dropping nothing would be FF accordingly. FF as a hexadecimal value equals 255 in the standard decimal system.

To make the numbers more readable, every number after being converted into decimal is then divided by 2.5. 255 divided by 2.5 equals 102, which is close enough to 100. Additionally, all of the numbers only go to the tenths place (at most) when dividing by 2.5.

To give an example, a Sciser has a 40% chance (out of 102%) of dropping big energy, and if it were out of 100%, then the chance would be 39.2157%, which is a negligible difference.

Bosses

Having a look at the drop table one can see that all non-Torizo Bosses own a uniqe drop table. All other bosses own a standartized drop table. Most notable the fact, that thoose 3 unique drop tables of Sporespawn, Crocomire and Botwoon have a chance to have nothing as drop.
