Thanos use his "life drain" on Mr Imortal
so Thanos use life force drain or w/e on Mr Imortal, wut happens?
IMO 4 things possible
1) Thanos drain all o his life, and he dies for good (cuz no more life force to sustain him)
2) Thanos drain all o his life, he dies but then he resurect & has new life (and Thanos can do it again (and again (and again......)
3) he has infinite life force so Thanos can keep on drainin 4ever like unlimited energy supply or somethin (a bit like Galactus vs Hyperstorm)
4) life drain trick dont work so Thanos dont drain anything
