Caleb Koch, age 16, resides in Canberra, Australia.

"Jeph is Dead"
Caleb became very distraught when he discovered that his brother Jeph was murdered whilst travelling in Texas. He planned to run away from home, but instead met Ryan who took him under his wing and consoled him. When they stumbled upon a crime scene, they were pursued by a mysterious stranger. This stranger asked for their 'help,' but when he pulled a gun on Caleb, Ryan intervened, using his cryokinesis. They escaped, but soon after, Katy Brooks, accidentally ran over Caleb's foot.
Convinced to make it up to him, Katy offered to buy Caleb lunch and the two began to form a romantic attachment. Ryan left the pair, and while at Katy's house, Caleb discovered that his substitute brother was on the run from the law.

Joshua
From an early age, Caleb found solace in an imaginary friend he named Joshua. Joshua was the same age and had the same appearance - as everyone around him said that when he talked to "Joshua," he was talking to himself, Caleb made it so.
Caleb never got out of the habit of talking to Joshua. Upon discovering his powers, he began to realise that Joshua was actually an early manifestation of his power.

Powers
