Specs is almost always seen with a serious demeanor. He is shown to be very anxious, which he tries to conceal to the best of his ability. Specs is shown to have a wide array of knowledge regarding Turf Wars, Ranked Battle modes, and various weapons, but he gets upset when others don't listen to the advice he gives. Like Headphones, Specs is shown to dislike the random shenanigans that Goggles gets himself into, like getting naked in public and pulling down the pants of various Inklings.
Relationships
Specs is shown to mostly get along with his teammates until Goggles or Bobble Hat goof off. He doesn't like when people think that Goggles is the leader of the team.
Trivia
Specs is the actual leader of Team Blue despite Goggles being the mascot of the manga.
Specs is near-sighted, as shown by the bonus manga for Volume 7.
It is possible that Specs is jealous of Gloves, as when Gloves often gets attention, Specs can be seen, flustered, in the background.
In the Square King Ranked Tournament arc, Specs is attacked by bees and is replaced by Emperor, similarly to Army.
