Occasional references to a character being a "slut"/"tralk" (in alien language).

Some scenes of bondage/BDSM (one with a character being under the influence of a drug).

A scene of sexual assault is played for laughs.

One scene has Chiana ask a 13 year old boy why he hasn't had sex yet, out of curiosity.

In the last season, one of the characters is repeatedly forced into a sexual relationship whilst intoxicated. Not graphic, but considered to be rape (off-screen) by most.

Frequent sexual references, occasional scenes of sexual activity with no nudity. Implied oral sex offscreen in a few scenes.

Mostly mild sci-fi violence. Some episodes feature more gruesome scenes including burned and melting body parts, beheadings, and loss of limbs.

Some scenes in which sexual assault is suggested. One of these scenes is sexual assault on a male character.

Moderate language such as "bitch", one "shit" in the episode "The Locket," and some crude dialogue. Most profanity is substituted with made up words e.g. frelling.

Characters sometimes get drunk or high on (fictional) drugs. One character uses a drug from her sweat to seduce male characters.

Certain animatronic characters are gruesome, some being genetic anomalies or characters made up of different alien body parts.

At times the show can be very dark, intense and suspenseful. Some major characters are killed.
