Mr. Higsby is obsessed with rare battle chips, and goes out of his way to collect them. When Lan and Ms. Mari show Higsby it’s wrong to harm others of commit crimes to obtain them, he opens up a battle chip shop as a way to show his love of battle chips, however he gets poor business as he refuses to sell his customers his rare chips. Even when supporting his friends, he will not surrender any chips that are worth anything, such as when he gave Lan a hand full of Mini Bomb chips during the N1 Grand Prix.
He is madly in love with Ms. Mari, and is a rival for her affection with Maysa, and the two often get into impassioned fights over her when the two meet, though when it comes to talking to her or confessing how he feels, Higsby freezes up and stutters.
He is poor at athletics, as shown when he wins bowling tickets and invites Ms. Mari to bowl (who invites Lan and Maylu Sakurai, much to his dismay), and uses NumberMan to cheat. He is also shown to be poor at directions, as shown when he gets lost with Shuko Kido while attempting to make a deal for rare chips.
Despite showing a spotty moral compass at times, Higsby does have a sense of compassion and comradery, as he often aids Lan and the others when they are in need, and uses his knowledge on battle chips to steer them away from dangerous ones. He also took Shuko in as an employee, despite her tendency to feel sorry for herself, as he saw her going through many of the same problems he has had with self-esteem.
In the Japanese version of the show, he often ends his sentences with “demasu”.
