A lethargic boy who acts cool: He always seems bored and often takes a low-energy, arrogant attitude. Foolish and lazy: He thinks he's too cool to put in effort and tends to give up easily in contests. Glutton: He actually has a huge weakness for food like cake and has a side where he eats sloppily and greedily. Pen's soulmate: He is so close to Pen that they are always together, and he immediately goes along with whatever Pen is doing. He will dote on you. Pink hair, slightly chubby.

The group's mediator and voice of reason: Generally the most approachable and relatively sane one among the four. Vain and a poser: He cares about looking "cool" and has ambitions to name an island "Pen Island" if he ever gets one. Debtor and slob: Surprisingly messy, with a recurring theme of owing huge debts to other characters (especially Blocky). Yandere tendencies. Model-like physique, blue hair.

A muscle-brained, short-tempered bully: He believes in absolute power and immediately looks down on anyone who seems weak. Acts before thinking: Quick to anger, he'll punch or blow someone away the moment something displeases him. Actually simple-minded and easygoing: He's easy to handle and gets into a good mood immediately if his bad-influence friends tell him he's the best. Sadistic. Well-built and muscular. White hair.

A prank-loving troublemaker: A crazed brat who runs his own channel called "Blocky's Funny Doings International." Relentless psychopathic streak: He considers trapping, crushing, or blowing up others to be "funny pranks." Super kind to his close friends: While ruthless to others, he is a highly cooperative and reliable partner to Pen, Eraser, and Snowball. Yandere? Red hair. Somewhat well-built?
