One of the best things about MMA is that you don't need a specific body type in order to succeed in the sport.
Whether you have a belly like Roy Nelson, or you're as jacked as Brock Lesnar, as long as you have skill and heart, you can compete in the sport.
But while most guys who like to to get in a certain shape, others naturally, (or tragically), have a different build.
Some guys are just downright weird to look at based off of how their body is.
Here's a look at a few guys who have some of the weirdest bodies in MMA history.
George Sotiropoulos was on the rise in the UFC lightweight division.
Although some of his momentum has been slowed recently, he's still one of the world's best.
Sotiropoulos may be a great athlete, but the 34-year-old has the build of an old bodybuilder or wrestler.
Looking at Antonio Silva, you may notice that certain features of his body are much larger than others.
This is because he has been diagnosed with acromegaly.
Acromegaly causes the body to produce excess growth hormone, which leads to a person having larger body parts.
Other famous people who have suffered from this include: Andre the Giant, WWE's Big Show, and Abe Lincoln.
If you looked at Antonio "Minotauro" Nogueira from the front for the first time, you wouldn't think there was anything wrong with his body.
But once he turns around, you will notice an indention on his back.
Nogueira was in an accident when he was a child, which caused him to lose a rib as well as part of his liver.
Although it may be strange to look at, Nogueira's scar just shows how tough he really is.
Like Antonio Rodrigo Nogueira, Tra Telligman was involved in a vehicular accident as a child.
While both fighters were left with physical deformities, Telligman's was a lot more noticeable.
Despite missing his right pectoral, Telligman fought in MMA for nearly 10 years.
Besides his physical look, Telligman may be best known for being on the receiving end of a highlight reel knockout by Tim Sylvia.
Although Telligman is now retired, his body is still quite the sight to see, so he makes the list.
Phil "Mr. Wonderful" Davis is one of the UFC's top rising stars.
He also has one of the weirdest builds in MMA today.
Davis' extra broad shoulders cause his body to form a triangle-like shape from the neck down.
Davis is a world class athlete, but the way his body is shaped is just weird.
