Yes, but even in the child timeline he has fearsome powers...

Touching the Triforce has something to do with it, but even before that he had extroadinary powers (like knocking young Link on his back with an energy ball). And I think he sometimes could turn into Ganon even before touching the Triforce.

I don't remember if he ever touched it in TP. Did he?
