Jeff spent most of his time with the WWE as one half of the popular Hardy Boyz, before branching out into a fairly successful singles run including a few midcard title reigns. He never seemed destined for stardom, however, until suddenly catching fire after his return from a stint with TNA in the mid-2000s. Out of nowhere, Jeff was the hottest commodity on the Smackdown brand, proving especially popular with women and children - an alternative answer to John Cena. He was never able to capitalise on this with a huge WrestleMania moment, however, his career falling victim to personal demons despite an amazing feud with CM Punk. Most Likely Opponent: Triple H. The pair shared a fair amount of interaction during Hardy's rise to prominence, the two babyfaces offering one another a wary respect. The Game is no stranger to putting younger stars over at 'Mania - just ask Batista and John Cena.
