#1 Finn Balor - 190lbs
The lightest Universal Champion of all-time only weighs 190lbs. The main reason is that he's extremely fit and shredded, which helps him to maintain his unique look.
Sculpted like an action figure, Finn Balor is one of the main roster's best wrestlers and is loved by most of the WWE Universe. He hasn't found as much success in the WWE as he deserves, though he could still go on to make it big sooner than later for the company.
Balor has previously performed for a few promotions, and his Bullet Club has been one of the most recognisable factions in the wrestling world. He has further gone on to create his own Balor club within the WWE too!
Finn's weight helps him perform some extraordinary moves and become a real threat to his opponents since he's both very agile and extremely talented.
