Undertale: The Musical Voice Actors
heyjude for Flowey the Flower/Asriel's Final Form
Flowey is the first character Frisk meets. He seems nice, but is actually soulless. He wants to obtain your soul to regain his real form and take over the undergroound. He is evil, manipulative and a bit maniacal.
Asriel's Final Form is seen for very little in the story. Frisk encounters him after Asriel utilizes the power of all 6 human souls and the monster souls. His goal is to kill Frisk, take their soul and destroy the world.
He sings a bass part
Clever. Verrrryyy clever. You think you're really smart, don't you? So you were able to play by your own rules. You spared the life of a single person.
I can feel it... Every time you die, your grip on this world slips away. Every time you die, your friends forget you a little more. Your life will end here, in a world where no one remembers you…
(0:21 to 0:32 of His Theme. The words match up with the lead track of the song)
CHARA, PLEASE JUST LET ME GO.
THOSE TIMES WERE LONG AGO.
YOUR DEATH IS NEAR, DON'T YOU KNOW?
JUST LEAVE ME ALONE.
