Dear  is a Janitor and a member of Team Child. Despite never being shown to speak, Dear has shown an ability to communicate exclusively with facial expressions and noises. Dear appears to be a generally irritable and intimidating individual, the messages read by Bro Santa seeming to display annoyance more often than not. He has shown irritation at Brot implying he’s shown some interest in Rudo, almost to the point of anger.

Dear also seems to despise being called nicknames (though this may be an annoyance with being called little) as when Bundus suggests calling him “Little Dear”, he is visibly angered. Despite his outwardly dismissive demeanor, Dear has shown no hesitation in displaying worry or concern when faced with a unique or dangerous adversary.
