Nightmare the Ex-guardian of negativity.

Nightmare was the guardian of negativity along with his brother who was the guardian of positivity, who is named Dream. Nightmare protects the negativity side of the tree of feelings and Dream protects the positive side of the tree.

Nightmare was hated for being the guardian of negativity - the same as his backstory - so after years of bullying he had finally had enough.

He grew jealous of Dream and decided to 'give up' by eating his own apples, causing him to corrupt the tree and make them completely negative.

Nightmare got corrupt by the apples and that painfully destroyed himself, until only hints shown through his left eye. The eye that was covered by the corruption.

'Nightmare' turns Dream into stone and he kills his bullies. He cuts the tree of feelings to the ground and looks around. *cool movie fade out*
