"He is a being alone in space, trying his best to find love in a vessel where he is the only one of his species." ― Norm Macdonald, voice of Yaphit[source]Yaphit is a gelatinous Lieutenant and Engineer aboard the USS Orville. According to Admiral Halsey, Yaphit was already an Engineer on the Orville prior to the arrival of Ed Mercer as Captain. In April, 2420, Yaphit is passed over for promotion to Chief Engineer of the Orville, for which he was considered next in line, in favor of Navigator John LaMarr.
Yaphit's voice is provided by Norm Macdonald.
Much of Yaphit's past prior to joining the Orville is unknown. Yaphit was "born" and raised on an unnamed home world. The way Yaphit came into being was somewhat convoluted. His mother created a novel Jelly being via mitosis and, later, the novel gelatin split via mitosis into Yaphit and his brother. 
Yaphit enlisted as an officer in the Planetary Union once he reached adulthood.
Yaphit is first seen in September, 2419. Shortly following the launch of the Orville, Captain Mercer accidentally tramples through Yaphit in a rush to the Shuttle Bay. Yaphit assures the worried Captain that he is unharmed.
For most of his tenure aboard the Orville, Yaphit works directly under Chief Engineer Steve Newton in Engineering. By measure of experience, Yaphit is the top Engineer of the ship, aside from Newton himself, and is considered next in line for promotion to Chief Engineer when Newton leaves in April, 2420.
To Yaphit's dismay, that promotion would never come. When Commander Kelly Grayson discovers that Navigator LaMarr boasts some of the highest performance scores in Union history, she becomes John's strongest advocate. She convinces Captain Ed Mercer to place John at the head of a joint Science and Engineering task force to research a nearby spatial anomaly. 
Yaphit quickly picks up that John is being tested for Chief Engineer - otherwise Yaphit would be in charge of the task force. He files a complaint with Captain Mercer, claiming discrimination against gelatinous persons.Meanwhile, the spatial anomaly turns out to be a pocket of two-dimensional space. With enemy Krill destroyers advancing from all sides, Yaphit comes up with the idea to escape into two-dimensional space by placing the Orville inside a quantum bubble that preserves three dimensions inside. While the plan initially works, but the "aperture" allowing the Orville to exit two-dimensional space closes early, leaving the ship stranded inside the spatial anomaly. Worse yet, the Orville is unable to preserve the quantum bubble. John convinces the Captain to project the bubble from a shuttle, and the shuttle would tow the Orville to a new distant aperture to return to normal space.
John's plan works brilliantly. Unfortunately, the crisis could not have come at a worse time in Yaphit's career. His idea to enter two-dimensional space was perceived as a mistake by the rest of Engineering, and sharply criticized. Even though John defends Yaphit by saying that he approved Yaphit's idea, and thus shares responsibility, Ed promotes John to Chief Engineer as soon as they return to normal space.
Conflict and relationship with Claire FinnEdit
Since Doctor Claire Finn's arrival at the Orville, Engineer Yaphit develops a profound romantic interest in her, often singing to her with a guitar or giving her gifts. After all, Yaphit prefers sexually and romantically Human women of color. Claire, on the other hand, finds Yaphit's persistent wooing to be uncomfortable and annoying.
In November, 2419, Yaphit begins feigning illness as an excuse to meet Claire in Sick Bay and ask her out on a date, which he attempts three times over the span of a week. After she turns him down, he makes a crude, sexual pass, after which she angrily demands he leave. His persistence grates on Claire, eventually acknowledging that she hates him.
In January, 2420, Yaphit learns that Doctor Finn's shuttle did not arrive as scheduled at Arboreus Prime, distressing Yaphit to know the object of his affections has gone missing. Claire's shuttle was damaged after a trip through an uncharted spatial anomaly and she is forced to crash-land on a nearby moon. Yaphit urges LaMarr not to get them lost as John leaves to search for her using star charts in lieu of the navigational array. Claire is later rescued.
A month later, Yaphit tries once again to woo Doctor Finn, and she rejects him - further insisting she will file a complaint if his unwanted advances continue. However, Yaphit had bumped into Darulio on his way to see Claire. Unbeknownst to Yaphit and Claire, Darulio, a Retepsian, produced powerful pheromones that sparks sexual attraction between carrier and recipient. Yaphit transmitted the pheromones to Claire, creating a powerful romantic and sexual interest in Claire towards Yaphit.
Claire and Yaphit begin a sexual relationship lasting several days until the pheromones wear off. During that time, Claire grows increasingly obsessed with the Engineer, which becomes dangerous during the Navarian-Bruidian conflict. Claire detains Yaphit at gunpoint from erecting a special barrier between the Navarian and Bruidian war fleets. Claire avoids punishment as she was under the overwhelming influence of alien pheromones, but Yaphit leaves Claire alone after the incident.
Based on comparisons with the original script and pre-production sketch, Yaphit is one of the least changed characters. He was based on an original sketch by creator Seth MacFarlane, which were fleshed out by Howard Berger. According to Executive Producer Jason Clark, "[MacFarlane] wanted to know if we could feature a CGI character that is essentially a gelatinous blob with a sloppy mouth hole." Armed with MacFarlane and Berger's designs, Clark approached Tippett Studios to turn the drawing into a fully-fledged, renderable model. Once Tippett's model of Yaphit was ready to be used, visual effects supervisor Luke McDonald made a 3-D printing of Yaphit for final approval.
According to Penny Johnson Jerald (Claire Finn), production staff places an object where Yaphit will be added during editing so that actors have a sense of where to look. At Jerald's request, an object was not used for scenes between Claire and Yaphit.
