Get the sephiroth mug.
A badass/popular/coolest villain fromFinal Fantasy 7who's doing anything to destroy the world with meteor and he made the main character/hero Cloud became angsty with taking away the person whom Cloud loved,Aerith by stabbed her from behind.Also he has a cool theme song "One Winged Angel".

Before Sephiroth was a good/sane guy and a hero until he went to Nibelheim together with Cloudand Zack,accidentally he found a Jenova's project there, his heart had torn into small pieces,hatred,pain,and sad for knowing the truth that he's nothing more than just an experiment,so misunderstanding happened when he thought that Jenova was his mother plus of his loneliness,finally,Sephiroth had chosen the wrong path where he ended up himself as a villain,and died in a fresh young soldier's hand.

Sephiroth is potrayed as a tall,long silver haired,slender and handsome/masculine figure.

In reality many fangirls like him because of his looks, and fanboys like him because of his badassness..
Sephiroth is a tragic villain...

The greatest game character of all time. He tried to use Meteor to damage the planet so he could absorb its energy to become a god, Safer Sephiroth is as close to a god he ever was he even had a kick ass theme song in this form (one-winged angel). In kingdom hearts some queer assholes played a cruel prank by casting Lance Bass as Sephiroth.
Sephiroth = teh master of all evil

An expression used in a Real Time Strategy to explain the One-Unit-Army, pretty much unstoppable unit of your force.
Dude...why does that thing have 200000 health, 100000 shields, and a firing range of half the map? Bit of a sephiroth you have there...

The bad-ass main villain of Final Fantasy VII.

In Advent Children, they made him look like a crack addict. Fuck them all.
If Sephiroth fought Master Chief, who'd win? - me

The best damn video game villain of all time and one of the hardest to beat. Sephiroth is an extreme hippie who's will do anything to save the plant even if he has to blow the motherf***er up to do so. One of the hardest things to beat is a villain who thinks he is the good guy
I still want to know who the f**k had the bright idea of having Lance Bass be Sephiroth in Kingdom hearts. Well atleast they got George Newbern for KH2

The god of all FF games period. The baddest villian ever to grace the videogame world. The One-Winged Angel. The guy with the 6' long sword that can utterly obliterate your ego in 5 seconds flat. He makes you feel so small.
"Aww man! Sephiroth just beat the CRAP out of me again!" "Dude, just give up. It's hopeless."
