[Marvel] Where does Juggernaut live? What does he do when he's not running through things and punching people?
gpt
SHIELD data seems to indicate that Cain Marko spends a significant amount of time using various civilian guises to live as a normal human when not actively being a supervillain. He's fond of going to bars, watching sports, and other mundane activities. He does cause far more barfights than most. He tends to use money from supervillaining to support these cover identities, which eventually either dries up or gets revealed, causing him to blow the cover and return to a life of running through things and punching people. He'll also occasionally crash with his hetero life mate Black Tom Cassidy in Ireland. It is assumed that Black Tom Cassidy is the one who arranges the false identities that Cain uses, as they stand up to sufficient scrutiny that he is able to use them for months at a time. 

As an occupational hazard, most heroes who fight the Juggernaut try to banish him to other dimensions or deep in space or the such because physically defeating him is nigh impossible, so he also spends significant amounts of time off world. But as he can not be stopped, he inevitably returns. 

He has had one short stint as an X-Man, having infiltrated the team claiming to have reformed, a longer stint as a member of the British super team Excalibur, during which time he lived in London but was an active superhero, but then fell back into old habits.
