10 Best WWE Ruthless Aggression Era Feuds

The Ruthless Aggression Era - beginning in 2002 after WWE lost its legal battle with the World Wildlife Fund, and ending six years later when they went all kid-friendly on us - will forever be known as the one after the (all things considered, much better) Attitude Era.

It derived its title from a segment shortly after the first brand split, in which Vince McMahon implored his roster to start showing some "ruthless aggression", a call answered by John Cena - who would, fittingly, go on to become one of the period's biggest stars.

And whilst it didn't have the same edge as the years that preceded it, no-one can say that it was lacking in high-quality wrestling. In fact, we probably got more of it than ever before, after SmackDown - particularly under Paul Heyman in 2002 and 2003 - became a decidedly more wrestling-based show.

Many of the Attitude Era stars (notably Stone Cold and The Rock) were gone, but in their place new stars - slowly but surely - emerged, and the feuds they fought were memorable enough, at least, for us to still be talking about them today.

Edge became the originator of the smash-and-grab Money in the Bank cash-in at New Year's Revolution in 2006, when he interrupted John Cena's post-match celebrations to win his maiden WWE Championship.

When he lost it back a month later at the Royal Rumble, paving the way for the Cena-Triple H match at WrestleMania 22, some feared that the Rated-R Superstar's moment in the sun had been and gone.

But he was back in pursuit of the title in the summer, and that's when his feud with Cena - culminating in one of the all-time great Tables, Ladders & Chairs matches at Unforgiven, in which the Champ beat his opponent at his own game (of course he did) - really came into its own.

Just don't mention that segment with Lita.
