Ninjago Head Canons

Sick

My theory is that when the ninja are sick their powers get a bit out of control (Rewritten)-

 Kai: has the unfortunate side effect of when he sneezes fire shoots from his nose and sometimes hands. Making it a bit dangerous if anything nearby is flammable. He also always tends to run a high temperature but her personally always feels like he's cold making it a complication with trying to get him to cool down.  

Jay: becomes extra shocky, his constant electric touch can cause anyone's hair to stand on end, and creates lil electricity with the blankets he covers himself with. His least favorite side effect is the problem of shocking the electronics, causing quick electric shortages, or entirely frying the item if it's small enough. 

Cole: Has shaken the whole house before when he sneezes and one time it was rumored he was the cause of a baby sinkhole that appeared in Ninjago after he had an intense sneeze. He often has the problem where his skin feels extra dry when he's sick, like dry, itchy sand. 

Nya: gets very sweaty, lots of cold, and hot sweats struggling with keeping a balanced temperature. She also has where randomly she'll move the water around her subconsciously, whether it's the tea in Wu's cup or the shower water, the water around tends to do what it's not supposed to. 

Zane: Like the others the sneezes tend to get the best of him whenever he sneezes, he sneezes snowflakes and sometimes solid ice causing things to fully freeze into solid ice; one time he even froze Jay by accident. Kinda like how Kai gets highly overheated, Zane becomes very shivery, and being a nindroid this causes his inner workings to process and move slower. He also is often followed by a small cloud of flurries. 

Lloyd: is the one who has the worst side effects when he's sick, having the elements of the other ninja, besides water. Lloyd finds himself in a constant roulette of element side effects. Randomly, he'll be shocky and cause static towards everyone, other times he too is followed by lil snow flurries and he also struggles with the intense temperature days. It's never a fun time when he gets sick, luckily for all the ninja Wu tends to always have the perfect tea to help them feel better.
