Fou-Lu

Fou-Lu is a playable character who appears in Breath of Fire IV. He is an Endless, improperly summoned to the world by the Fou Empire, and is the other half of Ryu. Due to this, both share similar (although polar opposite) abilities and strengths. While initially a playable character during a few segments, he eventually becomes the game's primary antagonist and final boss.

When he was summoned to the world, the summoning ritual was incomplete, so the soul of Fou-Lu was parted in two. The other part arrived in the world six-hundred years later than his alter-ego. Once Fou-Lu founded the Fou Empire, he fell into a deep slumber, awaiting the arrival Ryu.
