Find that picture on internet, its probably most popular of all and its strange that one is not on this site. So i just decided to upload, hope you enjoy.
Beyond Birthday (also known as Rue Ryuzaki/B, BB) was the 2nd child taken in at Wammy's House, in an attempt to create a successor for L, and was the serial killer behind the Los Angeles BB Murder Case.
Beyond Birthday has never appeared in the manga, anime, or film series to date, but the BB Case was briefly alluded to in both manga and anime. He was born with Shinigami Eyes, which allowed him to see and know when exactly people around him would die, as well as knowing their full names. He uses this ability to pick his victims and kill them when they would have been destined to die.
Little is known about B, though he and A (real name unknown) were the first two children in line to succeed L. The pressure of Wammy's House proved to be too great for A,which caused A to commit suicide, while B wound up running away at some point.
His whereabouts remained unknown from May 2002 to the beginning of the story, L having tracked cases around the world to search for him. Beyond Birthday came up with a plan to surpass L, as the "World's Greatest Criminal", giving L a case that B hoped he would be unable to solve.
On August 22nd, Naomi arrives at the location where the next BB murder will be committed, and comes to realize that Rue Ryuzaki, the mysterious private investigator she has been working with, isn't what he seems. After figuring out several clues, she finds that Ryuzaki is in fact Beyond Birthday, and that the final murder is actually his attempted suicide. She manages to stop B from burning himself to death, and arrests him.
A year and a half later, on January 21st 2004, Beyond Birthday dies of a heart attack in prison, presumably one of the many criminals killed by Kira. (If the events of this novel are canon to the anime as well, he would have died in 2007).
