Progenitor God Ruptured Heaven is Byleth's Final Smash. It has made its debut alongside Byleth in Super Smash Bros. Ultimate.

Byleth begins by lashing forward with his/her sword, shouting "I'll finish with this!". The game then shows Sothis in the background giving Byleth power, turning his/her hair green, and Byleth readies his/her sword, before extending it into its whip form, and lashing out once more with extreme force.
