steven cuz he died for pokemon.
i did not know that
Yeah, I didn't realize either, but according to the manga, he does die, and then gets revived by Celebi.
Apparently, they had taken steps to prevent Kyogre and Groudon from being resurrected - one of which was to seal the undersea chamber, the other was to have the Regis scattered in such a way that they could be retrieved with the appropriate keys to the locks - the relicanth, wailord, and the various acts.
Knowing he might suffer trauma, Steven stepped down and promoted Wallace to the champion (he rightfully was the champ, just didn't want the position or something). Anyway, controlling the Regis was a bit much, and he died wielding the power.
(Just felt I should make a mention).
