The first power is electrical resurrection, of either myself or others. The second power is anaerobic respiration.
While being able to live without breathing may be a bit more useful in everyday life, I'll pass it over compared to the other one. Even if I am unable to resurrect those whose bodies have been damaged extensively, being able to bring people back from heart failure, choking, drowning, and other low-damage deaths would be quite a nice ability to have.
It also means we could just sew the wound back up before I resurrect them, giving a higher chance of survival.
Much like Frankenstein, but instead of creating life, I would merely preserve it. And look pretty cool while doing so.
