The Man under the bed can be a friend if they are approached nicely. But. it will start being an enemy and try to kill if the thing that approached then was being rude. It uses He/Him pronouns and a very tall figure with claws for fingers. But knows how to be careful with theｍ．

A very nice thing to note : The Man under the bed will not attack children but will instead watch over them. It might even crawl out of the bed to hum or read a story to said child to sleep if it will not sleep.
