Duplicant
A Duplicant is one of the tiny, frustrating, but also endearing clones that the player manages in Oxygen Not Included. Each are printed with unique traits and have needs that must be fulfilled so they can survive. New games begin with a selection dialog where the player has to select three randomly generated Duplicants.
As the game progresses, a player may get more of them from the Printing Pod. You can also get a Duplicant from a Cryotank 3000 in the Spaced Out! DLC.
Duplicant Selection
New Game Menu
At the start of the game, as the last step of the Game Settings, three Duplicants are to be selected as the starting team. The player may reroll any Duplicants any number of times. Players can also select one interest for a Duplicant to guarantee they will have the selected interest when rerolling. The Duplicant can be renamed in this menu.
Printing Pod Menu
After the Printing Pod's cooldown timer is finished after 3 Cycles, it will become ready, giving the opportunity to either receive a new Duplicant or a Care Package. Unlike the start of the game, the Duplicants cannot be rerolled[1]. If no Duplicants are deemed suitable for the colony, you can reject all options. Exiting the dialogue will not reject the printing options and can be re-entered at a later time. The cooldown of the printing pod will not start until a Duplicant has been selected or rejected.
Starting Bonuses
When a Duplicant is rolled, one to three random interests will be chosen. Each interest provides a starting bonus to the related attribute. The amount depends on the number of interests that were chosen. One interest will result in a +7 bonus, two interests a +3 bonus, and three interests a +1 bonus to each attribute.
Extra points based on the Duplicant's traits may be applied. These can be found in the Traits section under the "Interest Attribute Modifier" column. If a Duplicant has more than one interest, the extra points are randomly divided across each of them.
In this example, the Duplicant has three interests which gives +1 to their associated attributes. The Unempathetic trait grants a +2 Interest Attribute Modifier. One of those is added to the Construction attribute and the other is added to the Digging attribute.
Note that Supplying and Tidying have the same corresponding attribute Strength. The bonus to Strength does stack, but the UI incorrectly displays the total bonus for both interests. If a Duplicant is rolled with both Supplying and Tidying, they will receive a +3 bonus to Strength for Tidying and +3 bonus to Strength for Supplying. This means the Duplicant will start with a Strength of 6. However, the UI will display "+6 Strength" next to both interests implying the Duplicant will get a +12 bonus which is not the case.
Duplicant Properties
Properties are aspects of Duplicants that aren't leveled and can't be intrinsically changed (as opposed to Skills). However, many Properties have positive and negative Traits associated with them.

Attributes
Each Duplicant has 11 different attributes. These attributes define how effectively Duplicants will perform those errands. Upon creation, Duplicant attributes are determined by their interests and certain traits. A negative Trait may lower a Duplicant attribute or prevent them from performing a specific errand.
All attributes can be trained by running related errands. This can increase an attribute by a maximum of 20 and is added on top of other modifiers.

Interests
Each Duplicant can have between 1 and 3 interests. Interests give bonuses to their related attributes, give a +1 Morale bonus for related Skills, and raise experience gain from associated activities, enabling skill points to be earned faster.
| Building | Cooking | Decorating | Digging | Doctoring |
| Farming | Operating | Ranching | Researching | Suit Wearing |
| Supplying | Tidying | Rocketry |
Traits
Inborn traits (traits duplicants start with) give bonuses or penalties to duplicants attributes. Negative traits may also make it impossible for a duplicant to perform certain Skills. Traits gained through certain skills mainly allow for the duplicant to use certain stations and perform certain errands.

Ownership
Individual duplicants can have ownership of certain structures: Cots, Comfy Bed, Mess Tables, Massage Tables, Med Beds, Lavatory and Pharma Chambers. Each Duplicant can only be assigned to one, and they can be reassigned by the player at any time. They will automatically select them for themselves if left unassigned, or the duplicant becomes sick.
Emotions
Duplicants occasionally express emotions or reactions to things around them. This indicates their status in ways that the player can keep track of.
