Some of the greatest stories that have been told on WWE TV over the years have involved real-life family members. This is because the closest relations often know the best ways to envoke a reaction and are able to put on a fantastic show.
When siblings make it to WWE together, it's always their dream to have a feud against one another, which is why more often than not WWE will allow family members to split apart so that they can then embark on a deeply personal feud against one another.
Here are just five real-life siblings who have had the opportunity to feud on WWE TV in the past.
New Champs in WWE! More RIGHT HERE
#5 Matt and Jeff Hardy went to war in WWE in 2009
Matt and Jeff Hardy lived the same dream for a number of years, since the two youngsters from Cameron, North Carolina started wrestling in their back garden from a very young age. The two brothers debuted on WWE TV together as The Hardy Boyz and went on to have differing success throughout their careers until they finally came to blows back in 2009.
In the build-up to WrestleMania 25, the two men had one of the most intense feuds after Matt cost Jeff his WWE Championship at The Royal Rumble. It was later revealed that Matt had set Hardy's house on fire and killed his dog.
This all came to a head at WrestleMania 25 in an Extreme Rules match that Matt Hardy won. The older brother then went on to win a stretcher match a few weeks later before the two men settled their rivalry in an I Quit match at Backlash that was won by Jeff.
This was ahead of Hardy's departure from WWE in the summer of 2009, which perhaps preventing the feud from going on for much longer.
#4 Humberto Carrillo and Angel Garza have fought many times in WWE
Humberto Carrillo and Angel Garza have only recently been introduced to WWE's main roster, but the real-life cousins have already faced off a number of times. Carrillo was on the side of Rey Mysterio when he debuted on Monday Night RAW before Zelina Vega brought Garza up to go against his real-life family member.
Garza got the better of his cousin in the feud and Carrillo was recently written off WWE TV for a number of weeks. The former NXT star made his return this week on RAW whilst Garza has most recently been part of a storyline with Andrade where the duo is looking to pick up the RAW Tag Team Championships.
Before being signed to a contract by WWE, Garza and Carrillo worked together on the Indy's a number of times which could be why the two men always deliver when they are given the chance to face off. Ahead of their main roster debut, the two men also wrestled on 205 Live where WWE must have seen their obvious potential.
#3 Nikki and Brie Bella fell apart following WWE SummerSlam
Nikki and Brie Bella rose to fame when they audition for WWE's annual Diva Search competition. They have since become the most recognizable female wrestlers in the world as former Divas Champions, WWE Hall of Famers, and the faces of Total Bellas.
Whilst Nikki and Brie have been able to turn their careers around since their return to WWE back in 2013, the two women were also given the chance to face off in a feud in 2014.Nikki turned on her sister Brie as part of her match with Stephanie McMahon at SummerSlam and what then ensued was a reality show level feud between the two sisters.
The feud wasn't on the level of many other sibling rivalries already mentioned on this list and at one point Nikki even told her sister Brie "I wish you died in the womb." The rivalry between the two women was seen as so bad by many wrestling journalists that it was voted the worst feud of the year for the whole of 2014.
#2 Tamina and Naomi
Tamina originally made her debut on WWE TV alongside her real-life cousins The Usos, since Snuka is related to The Usos and Roman Reigns via marriage. The fact that Tamina is related to The Usos means that she is now also related to fellow WWE star Naomi since she married Jimmy Uso back in 2014.
Naomi and Tamina's WWE careers have always been very closely linked together, since the two women were part of Team BAD alongside Sasha Banks back in 2015 and then went on to be part of their own team on SmackDown.
Even though they have shown that they are family and will always be on the same page inside and outside of the ring, the two women have had their own fair share of issues which has led to them facing off on WWE TV.
Back in 2014, Naomi was seen as one of the women on the side of Total Divas whilst Tamina was on the other side of the Women's Division which made the two women natural rivals.
#1 The Undertaker and Imposter Undertaker at WWE SummerSlam 1994
Throughout his career, The Undertaker was believed to be the brother of fellow WWE star Kane. This was because Paul Bearer was able to tell quite a believable story regarding the two men's upbringing and they then went on to have a fantastic feud.
In reality, Kane and The Undertaker are not related, but The Deadman has been able to feud with his cousin as part of the rivalry in WWE between The Phenom and the imposter Undertaker back in 1994.
Undertaker was missing after his loss to Yokozuna so Ted DiBiase managed to find "The Undertaker" and convinced him to join The Million Dollar Corporation. When the real Undertaker returned and defeated the imposter Undertaker at SummerSlam later that year, the storyline was dropped and Brian Lee was released from WWE.
Throughout the feud, there were many fans that noted the fact that both men looked very similar and this was because the man behind The Undertaker and the man behind fake Undertaker Brian Lee were cousins in real life.
