-Byakuya Kuchiki (Bleach)

-Itachi Uchiha (Naruto)

-Ky Kiske (Guilty Gear)

-Mitsuru Kirijo (Persona)

-Noob Saibot (Mortal Kombat)

-Sesshomaru (InuYasha)

-Vergil (Devil May Cry)

That's pretty much it and in case you wonder about Byakuya, Itachi, Noob Saibot, Sesshomaru and Vergil. It's pretty much whole the sibling rivalry/brother problems thing.
