I'd actually take Adam, and I don't consider what happened in WW3 jobbing because Black Adam is Captain Marvel's equal at normal power levels. If Captain Marvel Or Superman had gone on that same rampage everyone of the detractors in this thread would be hailing it as a top feat.
Well... I thought Black Adam sacrificed a portion of his power to heal Osiris in 52, who was subsequently killed without ever really returning the power and then Isis used her power to heal a dying Black Adam. I wasn't aware that she healed him from near-death and then amped him. Scans?
Black Adam gave a portion of his power to Osiris. Osiris died and the power came back (it's the same thing Billy has been doing for years). In fact, I remember Osiris's power flowing into Adam when he died, and this was the sign that he died.
Dying? I don't recall this.
Isis's power went into Adam when she died.
I'll look. Either way, I remember Adam being fueled by seven Gods as opposed to six.
^ You may be right. I'd still appreciate scans though. Y'know if they had not convuluted 52 with so many garbage storylines other than Booster Gold's, Question's and Black Adam's story, I might remember it better. It was definitely Black Adam's time to shine and it was just handled poorly. 52 could have truly culminated into a real World War III rather than the rush job it turned out to be. A shame. Only good thing was the resolution to Booster Gold's story. Too bad Jurgens couldn't keep up that momentum a year into his solo series.
It's been a while since I've read that story also. IIRC, Isis was independently powered by an artifact that Teth gave to her whereas Osiris received a portion of Black Adam's power. After their deaths Teth received the portion of power he'd given to Osiris back as well as the power he'd given to Isis (which was independent of his own power).
^ Well Osiris' power definitely returned to Black Adam. And that lightning bolt could be construed to be Isis' power flowing into Black Adam. But I'd be convinced by Black Adam stating that he was powered by seven gods rather than six.
