Zekrom is one of the legendary dragons mentioned in the myth of Unova’s founding, and represented Unova’s ‘Ideals’. Many years ago, it has turned itself into the Dark Stone for some reason, which was later uncovered by Clay at Desert Resort. Despite the Gymleaders’ efforts to safeguard it, Team Plasma eventually obtained the Dark Stone, and N resurrected Zekrom into its true form at the Dragonspiral Tower. Convinced by N’s ideals, it chose him as the hero and became its companion.
