Lol The Rock became a megastar cause of his look and promos, which couldn’t be duplicated or matched by D-Lo or anyone else.
Foley got over as a heel and face cause of his brilliant promos and creative abilities as well as the crazy bumps he would take and he was already a wrestling legend before he got to WWF.
The Big Show always has a role just like Andre always has a role cause this two were the only true giants in wrestling, and he was a former WCW champ. There have been other people similar to Kurgan’s size.
The Austin-Harris brothers isn’t even worth addressing
Outside of Big Show who was just big, you named 3 guys (Austin, Rock, Foley) that were savants at understanding how to connect with the audience and created their own characters.
Triple H just looked the part and made friends with the right people. There’s nothing he did that Val Venis or Billy Gunn couldn’t have done if booked in his role.
