Kelviin tries desperately to fit in with Humans and other common humanoids. To this end, he tries to model his behavior and appearance to blend in as best as possible. This obviously becomes difficult with his inability to speak Basic. To compensate, he relies on his datapad to run a text-to-speech program. Without his datapad, however, he can easily struggle to communicate with anyone who doesn't understand Shyriiwook, which can lead to him becoming easily flustered.

Every legendary story seems to have at least one charming and optimistic character. If that's the case, then it only makes sense that Kelviin has decided to be that person. After all, if everyone is too busy whining and groaning about the negatives, how will anyone ever reach the positive? True, Kelviin's constant belief that things will get better can be terribly grating, especially to pessimists or those just level-headed enough to realize when things truly are going downhill, but Kelviin's constant positive outlook can serve to sometimes spur others to action when it feels like the world just wants them to lay down and die.

Kelviin is a lateral thinker, and when he encounters problems or dilemmas, he is very good at improvising and coming up with alternative solutions. This allows Kelviin to find ways out of situations others might give up on. While these solutions are often not so obvious to others, Kelviin can typically explain and lead others through his plan...as long as they are patient and willing enough to trust him outside thinking.

Kelviin is mesmerized by anything shiny and can easily spot shiny objects from a distance. This makes him good at finding things of importance or value, but he may also be distracted by pretty baubles.

While not particularly good for direct combat in any way, Kelviin tries very hard to contribute his often unique and alternative perspective to a skirmish. If forced to fight, he will try to use his size and an array of gadgets and weapons in an unpredictable manner. For this reason, he favors the gaderffii stick because at the very least he can typically bludgeon things without having to rely on combat technique. He takes pride in being helpful, even if he's usually making things up as he goes.

Fond of staying alive and prepared, Kelvin Farrenhyte keeps several gadgets and blunt tools hidden on his person at all times and in all different locations. Kelvin Farrenhyte switches these locations periodically as they are used, modified, or broken. This constant cycling of items causes him to lose track of where he's stored things and often misplaces the tool he needs for a task.
