This article is about the former ghost. For the Steeper Wisdom customer, see Chuck (Wu's Teas).
“Okay, I'll just call you "Chuck." Look, Chuck, I know you think you're Yang's student, and maybe you were once, but now you're his prisoner. Don't you see? He's not your friend. He's your captor. You gotta shake off his spell. Then, we can stop him. Together. You and me.”
Cole to Jerahn, "Day of the Departed"

Jerahn[1] is one of Yang's former students, who received the nickname "Chuck" from Cole while he briefly stood guard over him.

History[]

Background[]

At an unknown point in time, Jerahn was among the students taken under Yang's teachings, with Yang becoming infamous for his strict methods on him. However, when Yang tried to use the Yin Blade on himself, he accidentally cursed the Temple of Airjitzu, transforming himself and his students into ghosts. At some point after that, Yang used the Yin Blade to enslave them to his will.

The Temple on Haunted Hill[]

As the morning came and the curse on Yang's Temple started to take effect on the ninja, he showed himself, revealing the student to be chained up, as he was imprisoned by Yang. The ninja then quickly fled to the entrance, not wanting to suffer the same fate as him and the other students. They manage to reach the entrance, but Cole dropped the scroll mid-way and thus had to go back in to retrieve it, which caused him to turn into a ghost. Fortunately, he escaped the temple before he can meet the same fate as the students.

Wishmasters[]

After Yang's temple was torn out of Ninjago to help construct Djinjago, he and the others left Yang's temple while Yang angrily confronts Nadakhan, claiming domain. However, the latter, unimpressed, promptly ordered Dogshank to shoot water at the students, forcing them to abandon the temple.

Day of the Departed[]

Yang later ordered Jerahn to capture Cole and stand guard over him while he set out to open the Rift of Return; Cole named him Chuck during this time and attempted to convince him to help him defeat Yang. The enslaved student proved deaf to Cole's pleas, forcing Cole to defeat him and set out to stop Yang alone. Jerahn later joined the others in battling Cole at Yang's command, but proved no match for him and was later freed after Cole overcame Yang. Jerahn and the others, as well as Cole then used the Rift of Return to return to human form.
