WWE NXT United Kingdom Champion WALTER has become arguably the most dominant champion currently on the WWE roster.
The Austrian WWE Superstar is the current reigning and defending NXT United Kingdom Champion and has held the championship for a record-setting 740 days.
During WALTER's epic title reign, the NXT United Kingdom Champion has defended the championship successfully against the likes of Pete Dunne, Tommaso Ciampa, Joe Coffey, Rampage Brown, Ilja Dragunov, Dave Mastiff and more.
One of WALTER's most recent NXT United Kingdom Championship defenses came against former NXT Champion Tommaso Ciampa at NXT TakeOver: Stand & Deliver Night One.
With WALTER seemingly conquering every opponent put in front of him, the question now becomes who can stop WALTER in WWE?
Let's take a closer look at five current WWE Superstars who could pose a legitimate threat to WALTER.
#5 Former WWE Champion Drew McIntyre
Former WWE Champion Drew McIntyre going toe-to-toe with WALTER is considered by many members of the WWE Universe to be a dream match.
The Scottish Warrior is currently engaged in a feud with current WWE Champion Bobby Lashley on Monday Night RAW over the WWE Championship. McIntyre is set for a WWE Championship WrestleMania 37 re-match against The All Mighty WWE Champion at WrestleMania Backlash.
However, once Drew McIntyre is finished with his feud with Lashley, could he potentially be set to feud with WALTER on the NXT UK brand?
A proud Scottish WWE Superstar, Drew McIntyre certainly fits in with the NXT UK brand as a British wrestler. Obviously there are issues with travel restrictions due to the ongoing global pandemic, but a feud between McIntyre and WALTER in the future isn't out of the realm of possibility.
Both superstars are well known for their physically intense matches. Therefore a match between Drew McIntyre and WALTER would be a real treat for all members of the WWE Universe to witness.
#4 Current WWE Champion Bobby Lashley
Current WWE Champion Bobby Lashley is quickly becoming the most dominant WWE Superstar currently on the Monday Night RAW roster.
The All Mighty champion captured the WWE Championship in March after defeating former champion The Miz. Since then, Bobby Lashley has successfully defended the WWE Championship against Drew McIntyre in the opening match of WrestleMania 37 Night One.
Bobby Lashley is currently scheduled to defend the WWE Championship once again against Drew McIntyre at WrestleMania Backlash next month. However, should Lashley defeat The Scottish Warrior, one could ask who is able to stop The All Mighty.
Perhaps the next credible challenger for Bobby Lashley's Championship could be the current NXT United Kingdom Champion WALTER. Some of the biggest matches in recent history have seen "the irresistible force meeting the immovable object." WALTER facing off against Bobby Lashley would certainly match that description.
Despite WALTER's recent dominance in NXT and NXT UK, could The All Mighty Champion be the one to finally defeat WALTER?
#3 Current WWE Universal Champion Roman Reigns
WWE Universal Champion Roman Reigns has raised his game to another level since returning in August 2020 at SummerSlam.
The Big Dog returned at SummerSlam and won the WWE Universal Championship seven days later at the Payback 2020 pay-per-view event. Since then, Reigns has turned heel on Friday Night SmackDown and aligned himself with Paul Heyman and Jey Uso, referring to himself as "The Tribal Chief" and "The Head of The Table."
Since returning last summer, Roman Reigns has also been undefeated in singles action, with no WWE Superstar officially pinning or submitting the current Universal Champion.
Reigns' recent dominance continued during the WrestleMania 37 Night Two main event where The Big Dog defeated Edge and Daniel Bryan in a triple threat match to retain the Universal Championship.
With fans questioning which WWE Superstar could be the one to stop WWE NXT United Kingdom Champion WALTER, Roman Reigns is certainly a prime candidate.
The two WWE Superstars boast the most recent and active undefeated streaks in WWE right now. A match pitting two seemingly unbeatable superstars would be a major, main event caliber match that the WWE Universe would be desperate to see.
#2 Former WWE World Heavyweight Champion Brock Lesnar
Since his WWE debut, many members of the WWE Universe have spoken of the desire to see a dream match between WALTER and former World Heavyweight Champion Brock Lesnar.
However, Brock Lesnar is not currently under contract with WWE. The Beast has not been seen on television since he lost the WWE Championship to Drew McIntyre in the main event of WrestleMania 36 Night Two in 2020.
It has since been reported that Brock Lesnar and WWE are yet to come to terms on a new contractual agreement. However, many insiders, reporters and analysts have stated that they do expect Brock Lesnar to return in the future.
Should Brock Lesnar return in the future, the former World Heavyweight Champion would be a perfect opponent for the current NXT United Kingdom Champion.
Brock Lesnar ended the most famous streak in WWE history when he defeated The Undertaker at WrestleMania XXX to end The Undertaker's WrestleMania undefeated streak. Could the former Universal Champion end WALTER's dominating undefeated streak?
#1 Current WWE NXT Champion Karrion Kross
WWE NXT TakeOver: Stand & Deliver Night Two saw Karrion Kross capture the NXT Championship for the second time in his WWE career as he defeated Finn Balor in the co-main event of the two night spectacular.
Karrion Kross is viewed by the WWE Universe as one of the most dominant WWE Superstars in recent history to perform on the black and gold brand. No current NXT Superstar has been able to stop the NXT Championship powerhouse.
However, could all roads be leading towards a showdown between the two male world champions of both NXT brands?
NXT previously held an event called "Worlds Collide" in 2020 where superstars of NXT and NXT UK battled it out. This resulted in a main event of WWE NXT UK's Imperium facing off against NXT's Undisputed Era.
Should WWE produce another Worlds Collide event in the future, we could possibly see a scenario where WWE NXT Champion Karrion Kross squares off against WWE NXT United Kingdom Champion WALTER.
A match between the two dominating powerhouses would be must-see television and result in one of the most physical matches ever seen on any of the black and gold brands.
