Cyan, as a teenager (in Mr. Erratum) is 8'0''. Fully grown he is 8'6''. This is how he looks after his partial order in both HWHBB and FiaDD unless stated otherwise. His clothes might change, but his body won't. The only thing that might change is height in FiaDD depending on where he lands. The same goes for the others.

He usually has a cold and serious look on his face, unlike before when he had a bubbly and happy one (even if it was fake later on in life). He is very protective over his friends and loved ones because of everything that has happened to him and others.

I hope that everyone enjoyed seeing him!
