Doomslug the Destroyer, or more commonly just Doomslug, is a taynix that Spensa Nightshade found on Detritus in the cave with M-Bot.[2][3] Spensa nicknamed her Doomslug the Destroyer and adopted her as a mascot.[4] She frequently accompanies Spensa on flights and is known to replicate nearly any sound she hears.[3]

Appearance and Personality[edit]

Doomslug is a yellow slug with blue spikes along her backside. She does not appear to have eyes, a mouth, or any of the components of a face, but her behavior reminds Spensa of a chipmunk.[3] When pleased, Doomslug emits a flutelike trill from her spikes.

Attributes and Abilities[edit]


As a taynix, Doomslug has the ability to travel at faster-than-light speeds by accessing the nowhere and can distract the delvers from the cytonic hyperjump so that they won't be drawn into the universe.[5] It is unclear whether or not Doomslug has or could learn any other Cytonic powers. As of Cytonic, she also has the ability to shapeshift and disguise herself as other objects, as seen when she transforms into Spensa's father's flight pin.


Doomslug can replicate any sound she hears with impeccable precision, though there is always a "distinctly fluty" sound to it.[3] She is also capable of slightly modifying the sounds she mimics, as shown when she accidentally corrects Spensa's grammar by saying "By whom!" in response to the question "By who?"


Doomslug is covered in blue spikes, which would make handling her difficult, and provides protection from predators. Her bright colors also lead Spensa to believe the possibility that she might be poisonous.[6] She is also capable of resisting minor increases in gravitational forces.


Early Life[edit]

Almost nothing is known about Doomslug's life prior to meeting Spensa.

Meeting Spensa[edit]

Doomslug took up residence near M-Bot after he was hidden by Commander Spears, who had flown his ship to Detritus in search of taynix slugs.[5] After Spensa arrived, the slug observed her, but engaged in minimal interaction. As their relationship progressed, Doomslug became more open, often enthusiastically repeating words and eventually complex phrases spoken by Spensa and Rig, as well as trilling in enjoyment when rubbed on the head.[6][7]

When Spensa began her first flight with M-Bot, Doomslug took residence in the seat behind Spensa.[8]

Adventures to Starsight[edit]

While undercover at Starsight, Spensa finds out that Doomslug is a taynix and has the capability to hyperjump ships.


Work? Work! Gone!

  • Doomslug is the Skyward-inspired cosplay Brandon is most excited to see in the future. [11]
  • Her diet consists of "mushrooms, among other things" and is rather plot-relevant.[12]
  • Brandon jokingly offered to give Doomslug a bow.[13]
  • M-Bot does not find Doomslug to be an engaging conversationalist.[13]
