STORY: As the new goddess council forms, they send Oliver to the depths of Mount Ebot. There, he falls into the underground filled with misery and vengeance. As he walks through the underground, he runs away from most monsters until the fight with Toriel, which reminds him of his mother Hera (Queen of the gods) and kills her in anger. After this, he goes on a rampage, killing every monster and corrupting his soul with each murder. Every time he kills a boss, a flower appears on his body and his soul. He eventually kills dust-sans and Chara; becoming the ruler of the underground and reforming the monsters into shadows.
The story took a long time to make, but the sprite matches. DISCLAIMER: This is not the final concept!! Just a draft concept for the sprite, the story is the same but the sprite will change soon.
