That's only regen unless stated and shown otherwise. Like Deadpool only has high-end regen because he can regenerate from massive attacks that still harm him--same with Mephiles.

Being immortal is the inability to die through different means. Mephiles, at best, has immortality types 1 (Because he is basically a copy of Shadow) and 3 (Due to his regen).

It can still be overwhelmed regardless.
