The Hardy Boyz forever inscribed their names in the annals of World Wrestling Federation history with their breath-taking performance in the Ladder Match at October 1999's No Mercy Pay-Per-View, when they defeated Edge and Christian in a ladder match.
Since then, the Hardyz have been a part of nearly every memorable tag team match the Federation has put on, including the infamous TLC Match from SummerSlam 2000.
With the lovely and high-flying Lita by their side, Matt and Jeff are top contenders for the Tag Team title, as well as likely singles title holders.
Still in their early 20s, Matt and Jeff Hardy are two of the youngest—and most gifted—high-flying superstars in World Wrestling Federation history.

Very Old Bio:

Still in their early 20s, Matt and Jeff Hardy are two of the youngest—and most gifted—high-flying superstars in World Wrestling Federation history. 
The brothers grew up as fans of the sport in their native Cameron, North Carolina, and chased their dream by competing in independent promotions across the country when they were barely out of high school. The duo was eventually invited to the Federation’s training camp, where they were highly impressive. As a result of their hard work at the camp, the duo have found themselves a full-time spot on the Federation's roster.
Now under the wing of Gangrel, Matt and Jeff have adopted a much darker attitude, and are now known as The New Brood!
