Audiences have a natural tendency to root for the underdogs. There's always something special about watching an individual overcome countless setbacks before winning the biggest prize. It's a frequent theme in all forms of media, but one that never loses its luster.

Underdogs can take a beating and move on to the next level undeterred. Their victories can feel like our victories while we sympathize with their losses. This list will cover the 10 most believable underdogs in WWE today.

10 Rey Mysterio

Often considered the greatest luchador of all time, Rey Mysterio has enjoyed a successful career spanning 25 years. His size and agility have allowed him to topple even the largest of adversaries. Whether plying his trade in ECW, becoming the face of WCW's Cruiserweight division or winning world titles in WWE, Mysterio has done it all.

The Masked Marvel made a triumphant return to WWE in 2018. He has had stellar performances against the likes of AJ Styles, Andrade, and Samoa Joe. His pedigree will always ensure a fighting chance in the eyes of fans.

9 Liv Morgan

Hard work doesn't always pay off in WWE. However, the crowd will always get behind those who persevere and give their all. Liv Morgan is just the latest example of that.

In the Riott Squad, she always took major risks in an effort to ensure victory. People have always rooted for her but she has never been taken seriously as a prominent star. With an overabundance of determination, Liv may rise through the ranks and achieve her goals.

8 Mustafa Ali

Mustafa Ali didn't come from a famous wrestling family or had connections in the business. He started out in the independents while working as a police officer. Despite losing in the first round of the Cruiserweight Classic, this would not be the end of his journey.

Ali's impressive 205 Live performances earned the attention of Vince McMahon, leading to his SmackDown debut. He has defeated many top-level stars and even lasted 30 minutes in the Royal Rumble. No matter where he lands, this thrilling superstar will always light the way to success.

7 Jeff Hardy

Jeff Hardy laughs in the face of danger and adversity. Going from a skinny teenager to a master of the ring, he took any risk imaginable to become the best. He is well known for his highly successful tag team tenures with his brother, Matt.

The Charismatic Enigma eventually went solo and captured several championships. He even took a daring step into the world title picture, defeating Triple H and Edge for the WWE Championship at Armageddon 2008. Jeff has made it a habit to defy the odds every time he steps in the ring.

6 Becky Lynch

Becky Lynch has been underestimated throughout her entire career. As a result, she was forced to take matters into her own hands. The Irishwoman rapidly made her mark on the WWE landscape, securing the Raw and SmackDown Women's Championships at WrestleMania 35. 

The Man went on to become the longest-reigning Raw Women's Champion, fending off numerous challengers. Her loudmouth style and fierce in-ring arsenal make her one of the most dominant women in WWE history.

5 Chad Gable

Chad Gable has more to offer than his booking allows. Underdogs exist in WWE not because of their height or determination, but the will of fans who want to see their favorites overcome the odds. Being on the losing end of feuds does not help his cause.

Whether it's in tag teams or in solo endeavors, Gable has proven that he has what it takes to become a major star. The company just has to get behind him first.

4 Kofi Kingston

Kofi Kingston spent most of his early years as a prominent yet underused mid-carder. He was often deemed a transitional champion, holding multiple Intercontinental and United States title reigns. His career dramatically changed when he joined forces with Big E and Xavier Woods.

The New Day has amassed 8 WWE Tag Team Championship reigns in their many years together. Kingston made some history of his own when he became the first African-born WWE Champion. It just goes to show what the power of positivity can do.

3 Johnny Gargano

Johnny Gargano has heard the word "no" more times than he can count. He was often deemed "too small" to become a contender in the wrestling world, even encountering an initial rejection from WWE. After a few unofficial appearances for NXT, he signed with the brand in early 2016.

Joining forces with Tommaso Ciampa as #DIY, the two brought NXT's tag division to new heights. He eventually went on his own and achieved limited success with the brand's top titles. In spite of his misfortunes, Gargano will never abandon his goals.

2 Sami Zayn

Sami Zayn used to be one of the most honorable, fun-loving competitors in WWE. By the time he finally won the NXT Championship in December 2014, it was taken from him in record time. His intensity only increased when he joined forces with his old rival Kevin Owens in pursuit of revenge.

Five years after his main roster debut, Zayn finally won his first Intercontinental title. It was taken from him in two months. It's very difficult to make him a villain when he has encountered so much hardship.

1 Daniel Bryan

Daniel Bryan was handpicked by the fans, not the WWE, to become a star. Years as a regular underdog and the "Yes Movement" led him to become WWE World Heavyweight Champion at WrestleMania 30. Two years after his initial retirement, DB took a darker turn after beating AJ Styles for the WWE Championship.

The American Dragon found himself in the fans' good graces once more after assisting Roman Reigns. He was later haunted by Bray Wyatt in a brief feud. Bryan is a relentless performer with a fighting spirit, and anyone who doubts him will face dire consequences.
