User LM
User LM is one of the Users. He lived in a palace in the sky, and drummed his fingers while wondering when the Architect and MakutaKlak would notice his posts.
He rarely deigns to show himself - indeed, his interactions with Perseus indicate he considers knowledge of the Users to be anathema.
His goals are unknown - though theories have been thrown around that he desires the eradication of all knowledge of the Users.
He does not know Poe's true origins - all he is aware of is that being's awareness of User MK's situation - as a result, he has sent Prime, the embodiment of his will, to destroy Poe.
During the Ascension arc, BBB kicked User LM into a stasis chamber in his own palace and froze him. He was later unfrozen and returned to BZPB with the other Users.
