Death's vastness holds no peace. I come at the end of the long road. Neither human, nor devil... all bends to my will.
The Demi-fiend, also known as Hitoshura, is a bad potential newcomer for Super Smash Bros. for Nintendo 3DS and Wii U. He is the protagonist of Shin Megami Tensei: Nocturne, the ultimate boss in Shin Megami Tensei: Digital Devil Saga (known as one of the hardest RPG bosses of all time) and is also set to appear in Shin Megami Tensei X Fire Emblem, proving his relevancy and relation with Nintendo.
Spoiler Warning!: Important plot details regarding Shin Megami Tensei: Nocturne will be mentioned here!
The Demi-fiend was originally an ordinary, unnamed Japanese high school student living in Tokyo. One day he decided to visit one of his teachers who was sick in hospital, when suddenly things went horribly wrong and he witnessed the end of the world. Mysteriously surviving, he was ingested with a parasite, becoming a demon and granting him the ability to recruit other demons. He then went on to explore Tokyo and discover his purpose within the new world.
Within the now spherical Tokyo, multiple organisations exist that each wish to rebuild the world in its own image. The player can decide in which way the Demi-fiend can rebuild the world, but in one path, he can side with Lucifer. If he does so, the Demi-fiend along with his demons kill Metatron, God's personal messenger and then later destroy creation itself. After that, the Demi-fiend is challenged to a fight by Lucifer himself and guess what, the Demi-fiend wins, becoming the Devil's greatest General. These important facts, along with all the other demons and people he defeated, most notably Dante, Son of Sparda and even Thor, prove that he is worthy of being a fighter in the Super Smash Bros. series.
