Which wrestler do you immediately think of when I say: "Streak"?

Yes, the one answer was exactly right and correct but The only one famous and more popular in this industry of wwe becasue Tatanka no longer exist in wrestling, I prefer more the Streak of Goldberg (173-0), I know that tatanka is strong and he have good technique But Goldberg is better and stronger, the stroy of andre the giant is pretty good and more good than tatanka, So what is my conclusion now... The Undertaker is the only one who appear in wrestling in these moments today and now. So immediately The Streak of the undertaker 18 - 0 at WrestleMania. The bookers gives undertaker any wrestlemania a victory so undertaker victorious and he's never lost at WrestleMania.
