Nah, he died when Sakurai touched him and put him in Brawl.
"Every character I touch who won't have a new game coming up is mine now." ~ Sakurai, when adding ROB in Smash 4.
Before, Wario was an anti-here, but he was also a crazy bounty hunter who could anything for money. With funny plateformers, Wario had a lot of success.
But then, Wario Ware came up. Wario was now a fat and lazy man, who rides a weirdly shaped motorcycle since he's not like any human being. He was weird, but still had his greedy personality.
And one day, one man came up. Creator of the Kirby series, Masahiro Sakurai decided to put Wario in his next Smash game, and decided to "remake the character a bit".
The result ? Wario is now known as a disgusting fat man, who farts on people, eats anything he sees and wants to stomp everyone with his bike. His bounty hunter days are gone now. The final nail of his coffin was in, thanks to Sakurai.
Wario is now a joke who'll never have a real game.
Why am I writing this anyway ?
