Lord is nothing more and nothing less than the physical form of the demon of greed Mammon.

He is a character that is characterized by appearing randomly in Sonic Adventure and Advance cartridges, he does what seems to be shows where he shows his best moves with his puppets and sings with his ominous voice, this is just a trap so that the boy who sees him falls hypnotized and gives him his soul, turning him into his eternal slave and jester for eternity that will help him get more souls and power

He can kill but he will only do it if he is not respected or if he sees you as useless

I miss the quiet
