Only their presence is intimidating; size does matter, but there's more.
The total package includes charisma, a well-done gimmick, at least one World Title reign, unreal strength, amazing endurance, and that little something.
All the wrestlers who made list reached the main-event level and most of them have headlined WrestleMania.
The following behemoths didn't make the list despite their size: Big Daddy V, Giant Gonzales, Mark Henry, Kamala, Snitsky, Earthquake and Mike Knox...
...so who are the most intimidating wrestlers of the last 30 years? Who's the intimidation total package? All of them have some of the requirements, but only one is the total package and he's No. 1.
At 7'1" and 420 pounds, he got the size, the unreal strength and a well done gimmick (when heel); but doesn't have the charisma, the endurance or that little something.
Still, he's a hero in India and he got a World Title in his record book.
He was not that tall, but he was a real bully. At 6'5" but weighing a solid 458 pounds, he could squash almost anyone.
He didn't win a single title in WWE, but his reputation was well known with his three WCW World Heavyweight Championships.
However, he marked WWE with his feuds with HBK and with The Undertaker, to help them building a part of their legacy.
Currently the largest athlete in the world, Big Show is now only the shadow of his legacy from his time in WCW and his beginning in WWE.
In 1999, he won the Tag Team Title twice with the Undertaker and his first WWF World Title.
Too bad he can no longer use his 7'0" frame and his 485 pounds to be the dominating heel he used to be.
At 6'9" he had an amazing psychotic gimmick and he was feared by all.
With his reputation earned from his run with Ric Flair's Four Horsemen and his NWA World Heavyweight title won against Sting, he later managed to win the WWF Championship twice to dominate the WWE in 1996-97 before his last run in WCW.
In his last years, from 1999 to 2001, he has been WCW Champion for some time before his major injury (broken leg - ED).
Since then, The Master and Ruler of the World only battled a few times in almost unknown rings.
The heaviest wrestler in WWE history deserves to be on that list.
He squashed jobbers and mid-card wrestlers from his debut in November 1992 to his Royal Rumble victory in January 1993; the same year, he won his first WWE World Title at the coming WrestleMania.
Yokozuna is even known at the one who ended Hulkamania, The Immortal (who left for WCW).
He has been involved in feuds with legendary wrestlers such as Mr. Perfect and Bret Hart, but after his storyline with The Undertaker, he slowly disappeared from the super stardom that only lasted a bit more than one year.
Call him Big Daddy Cool or Kevin Nash, his stint in WWE as Diesel has been one of the biggest push ever; in less than one year, he won the Intercontinental belt, the Tag Team championship and the WWF World Title.
He was certainly the most dominating wrestler between 1994 and 1996.
He had more than an impressive size at 6'11" with 320 pounds of muscle; he also had a huge charisma and that little something.
He has been in WWE at the right time, being associated with a rising star named Shawn Michaels.
In his prime, from 1997 to 2003, he was the most feared wrestler.
The Big Red Monster was the first to really physically dominate The Undertaker and he always been his nemesis in their feuds, when they were not together as the Brothers Of Destruction.
He's the only one to have made The Undertaker look human.
But, since the famous unmasking in June 2003, he is now called, by many, the Big Red Jobber.
Only the nostalgic fans will remember him as the wrestler who owns the record of 11 (the most in history) eliminations in one Royal Rumble match.
This mastodon is the best squashing machine ever. Unless he faced Hulk Hogan or Andre The Giant, he was unstoppable.
However, his biggest accomplishment in WWE is only the record he has set at the first WrestleMania; he pinned SD Jones in nine seconds for the shortest match in WrestleMania history.
Also, he is known, in his squashing gimmick, to ask the referee a five-count instead of the usual three-count.
The ultimate giant. He's a legend. Only he has ever been unbeaten for 15 years.
Then, the immovable object faced Hulk Hogan at the most famous wrestling match of all times at WrestleMania III. We all know the result; he made history in creating Hulkamania.
He then won the big title and tag team belts, but his legacy was already behind him.
When we talk about Andre the Giant, we talk about intimidation by size only; fortunately, he had awesome managers so he could be entertaining in his last run.
The Deadman, The Phenom, The Lord of Darkness; these are a few of his nicknames. Nothing can match the famous gong and the lights turning off.
The Undertaker built the best and most durable gimmick of all times. His legacy is based on intimidation; 18-0 at WrestleMania counts more than any amount of championships.
In addition, his promos are certainly the most intimidating in WWE history; the showdown leading to the 1994 Royal Rumble is probably the most intimidating one.
We could also only think about his entrance, the only one that can give the chills to everyone in any arena.
