Yazoo

One of the three main villains of Final Fantasy VII: Advent Children as well as the supporting antagonist of the Blank Points universe. He is played by Zidane as her main character, although this is usually up to debate, since it's a tie between Zidane Tribal and Yazoo.

As essentially the one who set in motion the now rampant destruction of life as we all know it, you can blame him for the untimely death of your nextdoor neighbor.

Oh, and he's one of the Remnants of Sephiroth. Fun times.

Blank Points Canon
Like everyone else who was dead at some point or another, Yazoo was revived in the Olypmic Coliseum after his suicidal attempt to kill Cloud Strife. After practically stumbling out of the Underworld, he came across Zack Fair as well as Cloud himself. Knowing that he was outmatched in every aspect, he felt a pull and noticed that he was being drawn to the abundance of Jenova Cells that still resided in the his system. In his desperation to even out the odds and to free a small piece of Jenova was born Zera. Both he and the new Remnant escape to the Realm of Darkness.

It is there that the two Remnants gather their strength and acquaint one another. Unfortunately, that included needling each other into cooperation as Yazoo is calm and collect while Zera is loud and wild.

From there, Yazoo and Zera attacked a number of worlds. The first world to be subject to their innate rage and hatred for all living things was Destiny Islands, home to Sora. Nothing was spared in the mass genocidal rampage.

Yazoo is the mother hen of the Remnants as they can never seem to ever get out of trouble these days.
