Chapter 2: Page 71 (Patreon)

Let me tell you a little bit about Malik's energy here.  If you have ever heard of the sensation "phantom Limb", that is basically what he has. His arm was cut off from the rest of his body, but his energy still flows. He's learned to control his energy very well and even move it around. Hence him creating this illusion of his arm-- his "phantom Limb". 

Also the color yellow-- we are going to learn later on-- is a very unnatural color for aliens. That's why Luca (and most aliens) dislike it.

Malik did not always have this yellow colored energy. But you will find out later as to why he does now. >:)

Malik can sense Luca...
