hola guys!..any suggestions on what the headline should be?

If por headline tu mean the tagline-type thing under the name of the club, I'm glad it's being changed. Suggestions...
The World's Greatest Criminal
The First to Challenge L
The Only Human To Possess Shinigami Eyes From Birth (a little long, but I'm just suggesting)
Antagonist of the L.A.B.B Cases

Somethin' like that. And if the icono was changed to, I'm sure a number of fans would appreciate it... he's not a cannibal, and that icono and the current headline kind of go together.
He usually looks better than that.
