A player can equip up to 3 evolved bacteria Evolved Bacteria at one time, but there are no limitations as to how many evolved bacteria Evolved Bacteria can be owned.

The evolved bacteria Evolved Bacteria that are equipped provide bonuses to production, increased critical strike chance and multiplier, reduced research time, and other positive effects.

When entering a [[Black Hole]], there is a default 90% possibility that an evolved bacteria Evolved Bacteria will die. Before entering, the player can secure two bacteria Bacteria that will definitely survive.

When the player destroys the fifth planet after the first Black Hole, '''[[Research#Bacteria Irradiation|Bacteria Irradiation]]''' is unlocked. It is accessible from the Research Lab and can increase the black hole survivability of an evolved bacteriaEvolved Bacteria.

:::::::Evolved bacteria Bacteria can be '''leveled up''' through [[Research#Bacteria Mutations|mutation]] at the [[Research|Research Lab]].

Higher level and higher rarity bacteria Bacteria are always stronger, but same level and rarity bacteria Bacteria aren't always equally powerful.

The number of stats that a bacteria Bacteria can have depends on its rarity, but not on the level:

|More gene strandsGene Strands

|Increases the chance that a tap will result in a [[Critical Hits|critical bacteriaCritical Bacteria]] by X percent.

|Increases the effect of the critical bacteria Critical Bacteria by X percent.

|Increases the speed the bacteria Bacteria are spreading in the population when attacking a planet by X percent, therefore, reducing the number of bacteria needed to destroy the planet.

|Reduces the duration of all [[Research|researchesresearch]] by X percent.

Level 1 evolved bacteria Evolved Bacteria can be discovered through '''Bacteria Evolution''' at the [[Research|Research Lab]].

Higher level evolved bacteria Evolved Bacteria can be obtained through [[Research#Bacteria Mutation|'''mutation''']] at the [[Research|Research Lab]]. Bacteria mutation is unlocked after the fourth planet.

Mutation requires two bacteria Bacteria of equal level and gives one bacteria Bacteria of a higher level as a reward. The rarity of the mutated bacteria Bacteria is the same as the rarity of the used bacteriaBacteria. If they are of different rarities, the mutated bacteria Bacteria will have a random rarity in the same range, so it is not possible to obtain a higher rarity bacteria Bacteria through mutation.

Each evolved bacteria Evolved Bacteria has a default 10% Black Hole survival probability. It can be raised through [[Research#Bacteria Irradiation|'''Bacteria Irradiation''']] at the [[Research|Research Lab]]. It is unlocked when the fifth planet after the first [[Black Hole]] is destroyed.

Viewing the survival probability of a bacteria Bacteria is possible after the first Black Hole. To do this, open the list of evolved bacteria Evolved Bacteria and tap on a bacteria Bacteria of your choice. The survivability should be visible just below the bacteriaBacteria's stats.

Evolved bacteria Bacteria can be deleted in the list of evolved bacteriaEvolved Bacteria. Deleting an evolved bacteria Evolved Bacteria doesn't give the player any reward.
