Tinker has had enough experiences in the past that shaped his circuit-brain's way of thinking. He is aware of its vast knowledge and isn't hesitant on making others know that, especially his owner Aru Law. However, he cares greatly for Aru Law and also others that have come to know him. Tinker is kind by nature and usually follows Aru Law around happilly, always asking others if they want caf. When it comes to action, and he is asked to do something, he almost always has a thing or two to say about it, and will not obey a direct order unless he actually thinks its the best way to do it.

Tinker has a light blue color as his main color around his body. Its legs are of a darker blue and the end of its legs are black. Dividing the main body and the head, Tinker has a dark orange stripe. On Tinker's center in the main body, there's an imprint of a sabacc card containing the number 0 in dark orange as well. Tinker's occular lenses are black but sometimes emit a bright red light when he's mad. On the lower part of its body, there are small detailed drawings in dark orange, including Arcona's and Qel-Droma's symbol, and a quote in Aurebesh that says: "There's more than one way to do it, even if it means cheating"

A basic toolkit has been integrated into Tinker, allowing it to perform easy or small repairs on other droids and technology
