M was a hivemind businessman in the video game industry, partnering with the Rockstar Daddy Dearest in the early 90s, he and Dearest earned millions each year, but Dearest betrayed M and sealed him in one of his own games, and there he laid for over 30 years. Now, he’s found out that Dearest has retired and had himself a wife and daughter, and Dearest’s son in law was a singer, so he shipped his game to them, and sucked them into his world, where he killed them. M is a cold killer, too.
