The monster, closely resembling him, didn't make him ask twice.
ROOOAR!
A sound blast exploded from its mouth, revealing its long translucent fangs in the process. Jake snorted, but stood still, letting the shockwave pass through him without flinching. His golden-silver hair was briefly slicked back, flapping as the gust of wind swept through it before falling down smoothly.
Then, Jake pointed two fingers at the creature's left eye, forming a gun with his hand, and an Air Bullet condensed with his mind hit the Digestor's forehead with a resounding bang. Like earlier, his head was thrown back, but his forehead was covered with a film of metal.
When the sparks from the impact disappeared, the metal layer disappeared, but his clone was no longer roaring with anger. If it hadn't tilted its head an inch to the side, the Air Bullet would have pierced its eye and reached his brain.
You may have noticed that I switch from "it/its" to "him/his" when referring to the clone.
Two reasons for this. The first is for readability. In some actions, if there were only him/his, it would be hard to know who is doing what.
The second reason is because it is a way for me to show how Jake perceives his clone. Sometimes he sees it as a monster, an alien, sometimes he sees him as a human being who looks a lot like him.
If it's confusing for some, I can stick to it/its for the following chapters.
