Nowadays, pro wrestling fans casually throw around the term "underrated." However, there's been only a handful of truly underrated and underappreciated performers throughout wrestling history. One of those performers was certainly Mick Foley. During his career, Foley brought unmatched versatility to the table.

As Mankind in WWE, Foley toed the line between a deranged schizophrenic and a loveable underdog beautifully. Foley even had incredible comedic timing. Despite being a huge star during The Attitude Era, Mankind was easily overshadowed by stars like "Stone Cold" Steve Austin, and The Rock. This may have led some fans to forget some pretty interesting things about the Mankind character.

10 Skipped Raw After The Montreal Screwjob

In November 1997, the entire wrestling world watched in shock as Vince McMahon screwed Bret Hart out of the WWE Championship on his last night in the company. At the time, it was the biggest controversy to ever hit pro wrestling. Internally, many WWE performers were extremely upset, as many of them had immense respect for Hart.

The Undertaker and Mankind were reportedly among the most upset performers. However, it would be Mankind who would go as far as skipping the following night's Monday Night Raw. Mankind claimed he needed time to process the incident. Luckily, there was never any backlash for Mankind missing the show.

9 Teamed With Vader

Some rivals have such great chemistry together that they go on to make incredible tag team partners. Mankind and Vader fall into that category. In WCW, Cactus Jack and Big Van Vader had worked predominantly as rivals. Their hard-hitting WCW matches still hold up today.

When the pair crossed paths in WWE in 1997, it would be as partners. The former rivals would form a formidable team and would even challenge Owen Hart and The British Bulldog for the WWE Tag Team Championships at WrestleMania 13. Unfortunately, Mankind and Vader's quest for gold wouldn't be successful. They'd eventually break up before Vader left WWE in 1998.

8 Chef Boyardee Spokesperson

Pro wrestling has perhaps never been hotter than it was in the late 90s. At the time, it seemed as though anything WWE touched turned to gold. During this time, guys like Steve Austin and The Rock had become household names and got plenty of endorsement opportunities because of it. They weren't the only ones though.

Believe it or not, even Mankind got in on the fun as a spokesperson for Chef Boyardee. Mankind would star in commercials and appear in advertisements and cardboard cutouts. The Attitude Era was a fun and lucrative time for many performers, including "Mrs. Foley's baby boy."

7 Only One Reign As Hardcore Champion

Throughout wrestling history, some championships have become almost synonymous with certain performers. Much like The British Bulldog and the WWE European Championship, Mankind is closely associated with the WWE Hardcore Championship. Much like Bulldog, Mankind was the inaugural champion.

What many fans forget though is that Mankind only had one brief reign as Hardcore Champion and never held the title again. He never even won the title in the first place. It was gifted to him by Mr. McMahon. Regardless, Mankind remains one of the performers most closely associated with that championship.

6 Called Goldust "Mommy"

To say that the Mankind and Goldust characters were shocking during their initial years in WWE would be a gross understatement. Upon debuting in the mid-90s, both characters made the WWE audience a bit uncomfortable. That was by design however as both characters were supposed to push their respective boundaries a bit.

Individually, both men excelled in their eccentric roles. When they joined forces though, things got a little weird. At one point during their alliance, Mankind started calling Goldust "Mommy." Mankind would also go on to call Sable "Mommy" during a brief program with Marc Mero. The whole ordeal was a bit odd but it fit the deranged Mankind's character at the time.

5 Had Different Entrance & Exit Theme Music

Since the 80s, entrance music has been a huge part of pro wrestling. Stars like Hulk Hogan and The Road Warriors could send fans into a frenzy with just the first few chords of their entrance themes. By the mid-90s, picking an entrance theme was part of developing a new character. When Mankind debuted in WWE in 1996, his musical choice, or choices, were interesting.

Mankind's entrance music would be an eerie, almost deranged tune. When Mankind won a match though, Ode to Freud would play as the maniacal Mankind rocked back and forth. Giving Mankind two different themes was such a simple component of the character but it helped enhance it greatly.

4 He Had A Mini

In the early 90s, it became apparent that WWE's magic carpet ride from the 80s was over. The company was losing a lot of steam and could no longer draw the same crowds it once did. This led Vince McMahon to try just about everything he could during the 90s to jumpstart his promotion.

This included bringing in some Lucha Libre elements in 1997 such as mini performers. It wouldn't be the first or last time WWE used mini-performers. This was the first time they ever portrayed full-sized WWE performers though. There would go on to be mini versions of Mankind, Vader, Goldust, and Paul Bearer. Not surprisingly, the mini-wrestlers never caught on.

3 Starred In Beyond The Mat

Today, pro wrestling documentaries are all the rage. Television networks like A&E and Vice have regularly pumped out well-received WWE documentaries over the last several years. WWE themselves produces hundreds of hours of documentary footage each year. In the late 90s though, wrestling documentaries were virtually unheard of. That is until Beyond The Mat was released in 1999.

The gritty film is still considered by many fans to be the greatest pro wrestling documentary ever. The film surprisingly featured some WWE performers like Mankind. The documentary paints a scary yet accurate picture of the dangers of the wrestling business. It's fair to assume that had Vince McMahon known what the film would turn into, Mankind wouldn't have been allowed to participate in it.

2 Guest Starred On Boy Meets World

Mankind was all over pop culture in 1999. That year, Mankind was surprisingly allowed to be featured in the wrestling documentary, Beyond The Mat. In early 1999, Mankind would also make his way to network television as a guest star on ABC's hit sitcom, Boy Meets World.

Mankind wouldn't be the first pro wrestler to be featured on the show. Vader had been a reoccurring guest on the program and Jake "The Snake" Roberts and Brother Love had even made a cameos once. Still, it was great to see Mankind get some well-deserved exposure on such a popular sitcom.

1 36 Total Days As WWE Champion

Becoming World Champion is the pinnacle of the pro wrestling business. It's the reason every performer gets into the business. To be a champion. Nothing affects a pro wrestler's legacy more than having won a World Championship at some point during their career. What many fans overlook is the length of the championship reigns. That fact seems to almost be irrelevant.

Mankind is a great example of how little the total number of days as champion means. Mankind is a former three-time WWE Champion. However, his three reigns only totaled 36 recognized days as champion. Regardless, Mick Foley's career is looked at differently because he's a three-time World Champion. That just goes to show how much winning a World Championship means compared to never winning one, in the eyes of fans.
