Lucid Sans

You were walking down the corridor, a familiar one since you'd been attending classes in this building on (your choice). Now the classes were over and you were heading home, when you noticed a strange monster by the mirror. Its eyes... they... changed color with each sentence it spoke; sometimes bright yellow, sometimes dark blue, sometimes dark crimson, and... and the voices were different... The skeleton clutched its head and squeezed its eyes shut. -Argh... guys, that's enough already! At that moment, he opened his eyes, and they were crimson.

Lucid Sans is a fusion of Dream and Nightmare. However, because the fusion is incomplete, Dream and Nightmare can control the body from time to time. Lucid Sans can hear their voices and respond to them, consulting them. He has tentacles made of positive and negative emotions, and Lucid is wary of apples, as that's where it all began.
