The Undertaker, Brock Lesnar and Giant all made big impressions on me the first time I saw them. Mostly due to their size. I was just a kid when Giant and Taker debuted in WCW and WWF respectively, so it really made a huge impression back then.
First time I watched a CM Punk match was his ECW debut, thought he was really good and been a fan ever since. Same also goes for Steve Austin, he was a Hollywood Blonde at the time I first saw him and was a fan of his long before he was Stone Cold, same goes for Pillman, he was great back then and also had that edgy attitude like Austin.
Those are just a few.
