Pin

Pin has light brown hair sticking out from under his cap and blue eyes. He usually wears a brown pilot's hat with goggles.

Pin is a Catholic, as in some episodes he recites the Latin prayer "Santa Maria" and crosses himself from left to right. Since childhood, Pin has been raised under strict discipline. Pin says of his homeland that anyone there will quickly become "as soft as silk." Therefore, he always follows strict instructions. Pin recalls going to bed immediately on command. Perhaps because of this strict upbringing, Pin differs from his friends. He sleeps little, but works hard, and also has a strange sense of humor—his jokes are not funny. It should be noted that Pin himself hardly approves of this upbringing, as he is very gentle with his "son" and does not welcome even such punishments as "standing in the corner."

Very sympathetic and kind, always ready to help a friend, and very understanding. Pin only gets angry at himself or his inventions when they fail again. Then it's really best to leave the inventor alone—he either lashes out angrily or becomes depressed. Because of such intense emotions over trivial matters, he has heart problems. In times of danger, Pin remains calm and acts coolly, without panicking.

A realist. Passionate about physics, he reads exclusively technical literature, rarely making exceptions. (Like comics)

Pin has a very busy schedule, so he rarely finds a moment to relax with friends. Pin is extremely honest and fair. He will never lie or try to shift the blame. Despite the fact that Pin's house, his hangar, and the junkyard are a complete mess, Pin believes there must be order in the universe.

Pin is very strong—after all, constant hammering and carrying all sorts of heavy parts couldn't help but take its toll. Pin also knows how to play soccer and hockey, and enjoys it.
