Seán

Seán is a part of JackSepticEye, and is the protagonist of The BOSS is Nothing and the antagonist of The BOSS.

Appearance
Sean looks identical to Jack, except his hair is brown instead of green. He has stubble and blue eyes, and he is seen wearing a grey hooded sweatshirt and jeans.

Personality
Seán is significantly more depressed and apathetic than Jack. He is the embodiment of JackSepticEye's more mellow and calm side. He describes how he feels like a sort of hole in him as if he's incomplete. He seems to get angry when the subscribers call out to "Jack", completely ignoring his existence. As a result of this, he seemed to be angry and vengeful during his fight with Jack in The BOSS.
