Terry is a Shlorpian.
Terry originates from planet Shlorp, and belongs to the Shlorpian race and was recognized as a pupa expert despite cheating in most of his classes. When his planet discovered that is was going to be destroyed by an asteroid, he was partnered with Korvo, and they and their replicants, Jesse and Yumyulack, boarded a ship and escaped the doomed planet. After some time in space, they discovered earth, and, believing the planet to be uninhabited, made a crash landing, only to discover that earth was already overpopulated and that the ship was too damaged to fly, forcing them to settle in hopes of making a decent living. They are, for the most part, not fully adjusted to Earth's customs - and Terry and his family try to overcome the challenge of being immigrants to a relatively unknown planet. Because of their inexperience, the Shlorpian family gets themselves in wacky hi-jinx.
Terry is an alien called a Shlorpian, which originates from the planet called Shlorp. His skin colour is lime green, and he has dark green spots on his forehead. Terry tends to dress in casual attire. He is mainly shown wearing a orange shirt with the label, "All About That Base", burgundy shoes with a blue light on them, and black shorts. He also has a knack for wearing shirts which contain references to pop culture, like "All About That Base" (a reference to Meghan Trainor's "All About that Bass"), "Got Diff?" (a reference to Got Milk?), and many more.
Terry is a very laid-back, open-minded and friendly alien. Unlike his partner Korvo, he is fairly optimistic about his entry onto planet Earth, and seems very indifferent about the fact that there are many forms of sentient life on Earth.
Despite being an immigrant to Earth, he is very open-minded about Earth's customs. He takes a liking to some customs in Earth - like purchasing lottery tickets, watching TV (shows like Funbucket), going to dog parks, dogs, and donating money. His outlook seems to be that he wants to have as much fun as possible on Earth and to seek cheap thrills from the planet.
Terry is also shown to be very caring and kind to those he cares about. Although Korvo tends to dismiss Terry's cries for affection, Terry is constantly shown complimenting him and even goes as far as to cheer Korvo up about the fact that their planet got destroyed.
Terri was Terry's lifemate back on Shlorp.
- In the pilot episode "The Matter Transfer Array", Terry is shown to be left-handed when he is eating ice cream
