They really are amazing; I love L, though I haven't gotten to watch the entire Death Note series yet. I also haven't been able to read the manga or anything, but I've looked into the anime itself quite a bit. I've never heard of Beyond Birthday, but I looked it up -- apparently, Beyond Birthday was supposed to be the second child who was to be the successor of L if he died?
Kane was always one of my favorite wrestlers; dark and brooding. I also love The Undertaker, but prolly not as much as Kane ever since he got his mask back. Speaking of dark wrestlers, have you ever heard of Abyss, Rellik, or Judas Mesias? They all used to be pretty big stars on TNA and all wore masks at one point; they're also all sinisterly badass as fuck.
