Bubbles is a female robot that was involved in an underground robot-fighting ring.

Her speech patterns are formal and erudite.[1] She also does not enjoy nicknames, having rejected Faye's labelings of "Bubs, Miss Bubbles, PALKyrie" and "Large Metal Friend."[2]

Biography Edit

She suffered from PTSD after her military career; those memories were claimed to have been locked away by Corpse Witch, who held the unlock key as leverage over her,[3] although when Spookybot intervened it was revealed that the memories were accidentally lost in the process.[4]

She greeted and screened visitors and performed repairs on the fighters in Robot-Fighting Ring.[5] She did not fight,[1] and finds robot fighting "grotesque".[6]


Bubbles without her armor in Number 3475: Range Of Motion

Her armor was both a physical and a psychological defense. She has continued to wear it without any practical need and has been unwilling to take it off until a recent milestone in her recovery. Faye helped Bubbles take off her armor.[7] Since removing her armor she appears to wear a maroon bodysuit with short sleeves and legs, which is removable. She has been seen wearing a hoodie and jeans.[8]


Bubbles discusses human-AI relations with Evie in 3656

She currently works at Union Robotics, a robot repair shop she started with Faye.

Bubbles did not appreciate some of Evie's commentary about AI-sociology.[9][10]

Personality Edit

Relationships Edit

Bubbles may feel misunderstood on account of her size.[11] It is maybe related, or maybe not, that she is socially withdrawn.[12]

It took time for her to become friends with the rest of the characters. Since then she has shown concern for Faye's well-being and was sympathetic to Claire's gender dysphoria.[13]

She is extremely close with Faye. Eventually her feelings for her became romantic. She was initially unsure of what to do about those feelings because she didn't believe that Faye reciprocated them. However, after discovering that Faye had similar feelings for her too, they entered an intimate relationship.

Tea Edit


Trying tea for the first time

Although Bubbles cannot eat, she has highly-calibrated olfactory sensors- whenever visiting Coffee of Doom she will order herbal tea because she enjoys the aroma. Hannelore takes pride in brewing tea for Bubbles;[14] the resulting blends have allowed Bubbles to see a variety of mythical creatures.[15][16][17][18]

Claire once tried to make tea for Bubbles, but failed.[19]

Appearance Edit

With armor on, the abs of Bubbles are like "a slinky full of ball bearings".[20][21] Before Bubbles took off her armor, Faye sometimes hit her head on Bubbles' chest plate.[22][23][24]

Bubbles styles her hair herself.[22][25]

Equipment Edit

Bubbles has an olfactory system tuned to detect chemical and biological weapons.[14] Her muscles are triple-reinforced myomer. Her armor is a metallo-ceramic material, possibly Chobham armor, and can resist a 3 cm APFSDS round. Also, her armor can be removed[26]. She is capable of a top running speed of 30 km/hr and a 3-meter vertical leap[27]
