Dimorus

Dimorus (also called Dimorus IV) is the fourth planet in the Dimorus system/Tarod sector which was the homeworld of the Dimorusians, a race of poisonous dart-shooting rodents.

History and specifics[]

This class M planet lacked an ocean. Complex underground reservoirs of water on Dimorus IV fed dense underbrush and forests throughout the surface. (ST reference: The Worlds of the Federation)

It had at least one moon. Animal lifeforms included six-legged Dimoran butterflies and small four-legged dinosaur-like reptiles with pointed spikes along their backs.

Dimorus was considered a recent discovery in the 2250s. Starfleet oversaw a six-month orbital study, but when results were inconclusive, a seven-member Human survey team visited the surface for three weeks in 2254 to clandestinely observe the natives. (TOS comic: "Gary")

In 2265, the starship USS Enterprise orbited Dimorus and beamed down a landing party. (TOS episode & Star Trek 8 novelization: Where No Man Has Gone Before, TOS - My Brother's Keeper novel: Enterprise)

Most sources reported that the planet was inhabited only by natives. However, the Enterprise visited in response to a distress call from a Federation colony there, in TOS novel: Captain's Peril.

After inspecting a seemingly empty rodent village, the landing party was ambushed by aggressive natives. Pete Rossi was hit by a dart and died within seconds. (TOS - New Visions comic: "Strange New Worlds")

Lieutenant Commander Gary Mitchell was shot with one of the poisonous darts, which was intended for his friend Captain James T. Kirk. (TOS episode & Star Trek 8 novelization: Where No Man Has Gone Before, TOS - My Brother's Keeper novel: Enterprise)

According to a conflicting account, the incident occurred in 2255, not long after Lieutenant Kirk's visit with Tyree on Neural. The USS Farragut responded to a distress call from an anthropological team sent three weeks earlier to study the natives. In this account, the Dimorusians were Human-sized, and the incident was resolved peacefully, with Mitchell cured by the natives. (TOS comic: "Gary")

Several other expeditions have visited Dimorus for botanical laboratory research. (ST reference: The Worlds of the Federation)

The Federation eventually quarantined the planet due to dangers posed by the natives. (ST references: The Worlds of the Federation, Star Trek Maps; FASA RPG module: The Federation)

In 2268, a non-corporeal version of Gary Mitchell re-enacted the poison dart incident as a shared illusion for Leonard McCoy and Spock, with McCoy in the role of Mark Piper. (TOS - New Visions comic: "Strange New Worlds")

In one alternate reality, Kirk was not present during the incident. Three darts hit Mitchell and left him with a permanent limp, enough to deny him further starship duty. A retaliatory strike killed a large number of the natives. (TOS - Myriad Universes - Infinity's Prism novella: A Less Perfect Union)

The incident may not have occurred in the Kelvin timeline. Instead of mentioning it on Delta Vega I as he did in the prime reality, Gary Mitchell showed James T. Kirk illusions of the Iowa bar and taking exams at Starfleet Academy. (TOS - Where No Man Has Gone Before comic: "Part 2")
