Much like his companion Uzi, Thad has a streak of bravery that most other Worker Drones lack. While this first showed itself in his willingness to speak to Uzi (while others wrote her off as a weirdo), he was also willing to stand up to Disassembly Drones despite how their combat ability outclassed his in every conceivable way. 

It is perhaps this willingness to act that led him to be so disgusted with the Worker Defense Force after they froze up when confronted with a genuine problem - one that couldn't be solved with their doors. He also appeared to have believed the various posters tacked within their colony and was shocked when Uzi's own father left her to die instead of making any attempt to assist her at all. 

Thad is also quite the loyal friend, leaving the safety of the colony just to give Uzi back her railgun, which she had previously left behind after departing on a self-imposed exile. He also accompanied her and N to investigate the enigmatic disappearance of a Worker Drone, and after being captured by the culprit and freed by the duo, he even speaks disparagingly to his former captor. 

Generally, his behavior is similar to that of a high school jock, though is noticeably kinder than his peers. -Moashbolt (Voice reference) https://youtu.be/C5DnV6_J85Y?si=4toCk44tWjdq9vEa
